This certiorari
I
In September 1985, Colonel John Dempsey, Chief of the Colorado State Patrol, issued an “Operational Procedures Bulletin” authorizing the use of sobriety checkpoints “to reduce the number of motor vehicle accidents in which alcohol is a contributing factor” and “to aid in the detection, apprehension and/or deterrence of drivers who are intoxicated or under the influence of alcohol.” The bulletin set forth numerous procedures to be followed in establishing and operating a sobriety checkpoint, including providing the criteria for selecting a sobriety-checkpoint site, and the physical requirements of a checkpoint site. The bulletin provided that:
As each vehicle is contacted the trooper will approach the motorist and state “This is a Colorado State Patrol Sobriety Checkpoint set up to determine the sobriety of drivers.” The trooper will then normally ask for the driver’s license only. If during this brief encounter the trooper perceives no evidence of alcohol impairment, the motorist should be allowed to proceed immediately, being assisted back into traffic by an officer. Constitutional rights of motorists must be foremost in the minds of our officers. The purpose of a sobriety checkpoint is deterrence/apprehension of DUI. If other types of violations or articulable suspicions of other violations are immediately discernible, those may also be investigated; however, as a general rule, the encounter involving checking the driver’s license should be adequate to determine any evidence of alcohol impairment.
During the stop, the trooper will be alert for any articulable conditions normally associated with persons driving under the influence. These conditions would include, but not be limited to, odor of alcoholic beverage about the driver, slurred speech, flushed appearance, disorderly or unusual conduct, visual disorders and/or lack of muscular coordination. In the event any condition or combination of conditions exist which give the trooper probable cause to believe the driver may be under the influence of alcohol, the driver may then be requested to perform certain psychomotor coordination tests and/or submit to a chemical test of either his blood or breath. Ifsufficient evidence of intoxication is then developed, the driver will be arrested.
The bulletin provided that state patrol officers would take no action against motorists who make “an apparent attempt to avoid the checkpoint” by turning around or turning off the highway before reaching the checkpoint, unless “a specific action other than merely turning around would justify pursuit.” Moreover, the checkpoints would be maintained for a predetermined period of time, but would be canceled if “significant traffic congestion at the site or other circumstances arise ... as determined by the on-scene officer-in-charge.” Under the procedures outlined in the bulletin, the state patrol would publicize the use of sobriety checkpoints and the dates of their use to deter alcohol-impaired driving, but “the exact location and times of scheduled checkpoints will be kept confidential.” Written instructions corresponding to the bulletin’s specified procedures would be provided to all officers operating the checkpoint.
Lieutenant Ralph Martin of the Colorado State Patrol authorized a sobriety checkpoint in Jackson County to be implemented on July 5, 1986, a Saturday during the Fourth of July weekend. The checkpoint was to be located at the three-way intersection of Highway 14 and County Road 12. On July 5, six state patrol officers, who had been given specific instructions on how to conduct the checkpoint screening of vehicle operators, set up traffic cones in the intersection demarcating two adjacent, off-road areas in which vehicles would be directed to stop. One “stop area” was located on the northwest corner of the intersection, and vehicles southbound on Highway 14 were directed to stop in that area. Another stop area was located on the east side of the intersection where a dirt parking area was located, and vehicles northbound on Highway 14 and eastbound on County Road 12 were directed to stop there. Signs stating “Be Prepared to Stop” and “sobriety checkpoint” were placed two-tenths and one-tenth of a mile before the checkpoint.
The state patrol operated the checkpoint for two and one-half hours, from 4:30 p.m. to 7:00 p.m., and stopped 233 vehicles that entered the Highway 14-County Road 12 intersection. All vehicles were stopped; however, officers diverted all traffic past the checkpoint on a few occasions when volume would not allow additional vehicles without creating safety hazards or imposing unreasonable delay to motorists. The average stop lasted three minutes. Several vehicles turned around or turned off before reaching the intersection, and the state patrol did not attempt to stop them.
The defendant, who was eastbound on County Road 12, was asked to drive into the checkpoint stop area when he came to a stop sign at the intersection. The defendant requested permission to turn right at the intersection and proceed south on Highway 14. The officer denied the request and directed the defendant into the parking area. After the defendant parked his car, two state patrol officers saw the defendant and the passenger in his car leave the car and switch places so that the passenger was sitting in the driver’s seat. An officer subsequently checked the defendant’s driver’s license on a computer and found that his license had been denied. The officer then issued the defendant a summons and complaint charging him with driving a motor vehicle while license denied in violation of section 42-2-130, 17 C.R.S. (1984 & Supp.1990).
The defendant moved to suppress “any statements or observations made by law enforcement officers surrounding the seizure and arrest of the defendant” on the ground that there was no probable cause to seize and detain him. Following a suppression hearing, the county court ruled that since the stop was not based on probable cause or reasonable suspicion it was unconstitutional under the fourth amendment of the United States Constitution and article II, section 7, of the Colorado Constitution, and suppressed the prosecution’s evidence against the defendant. The district court affirmed, holding that “seizures must stem from probable cause or at least an articula-ble suspicion, the use of warrants or at least legislative authority.”
The fourth amendment, which is applicable to the states through the fourteenth amendment,
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the person or things to be seized.
Because we are bound by the United States Supreme Court’s decisions concerning the fourth amendment, People v. Quintana,
Although the state patrol’s stop of the defendant’s vehicle was brief, the stop was a “seizure” under the fourth amendment. Michigan Dep’t of State Police v. Sitz, — U.S. -,
Recently the United States Supreme Court considered the constitutionality of highway sobriety checkpoints in a case similar to the one now before us. In Michigan Department of State Police v. Sitz, — U.S. -,
Under the guidelines, checkpoints would be set up at selected sites along state roads. All vehicles passing through a checkpoint would be stopped and their drivers briefly examined for signs of intoxication. In cases where a checkpoint officer detected signs of intoxication, the motorist would be directed to a location out of the traffic flow, where an officer would check the motorist’s driver’s license and car registration and, if warranted, conduct further sobriety tests. Should the field tests and the officer’s observations suggest that the driver was intoxicated, an arrest would be made. All other drivers would be permitted to resume their journey immediately.
Id.
“[A]ddress[ing] only the initial stop of each motorist passing through a checkpoint and the associated preliminary questioning and observation by checkpoint officers,”
Applying the balancing test for checkpoint stops as enunciated in Sitz,
The Highway 14 checkpoint stops suffer from none of the defects the United States Supreme Court found to contribute to the unreasonableness of police searches and seizures of vehicles on the open road. The primary evil the Court sought to prevent in random stops of vehicles was “the ‘kind of standardless and unconstrained discretion’ ” present in those kinds of stops. Sitz,
“[T]he subjective intrusion — the generating of concern or even fright on the part of lawful travelers — is appreciably less in the case of a checkpoint stop. In [United, States v.] Ortiz, [422 U.S. 891 ,95 S.Ct. 2585 ,45 L.Ed.2d 623 (1975),] we noted:
“ ‘[T]he circumstances surrounding a checkpoint stop and search are far less intrusive than those attending a roving-patrol stop. Roving patrols often operate at night on seldom-traveled roads, and their approach may frighten motorists. At traffic checkpoints the motorist can see that other vehicles are being stopped, he can see visible signs of the officers’ authority, and he is much less likely to be frightened or annoyed by the intrusion.’422 U.S., at 894-895 [95 S.Ct. at 2587-2488 ].”
Sitz,
The final factor to consider in the Sitz balancing test is whether the Highway 14 checkpoint reasonably advanced the state’s interest in combatting drunken driving. The question this factor presents is whether in the furtherance of the state’s legitimate goal of combatting drunken driving the checkpoint stop “is a sufficiently productive mechanism to justify the intrusion upon Fourth Amendment interests which such stops entail,” Prouse,
The state patrol set up the checkpoint site on Highway 14 on the basis of information that drunk drivers had been arrested or had been involved in accidents on roads, such as Highway 14, that provided access to nearby recreational sites.
As we view the balance of the competing interests involved in the sobriety-checkpoint stops conducted by the State Patrol in this case, the relatively minor intrusion on the motorists’ fourth amendment rights to accomplish the state’s objective of reducing drunken driving was not unreasonable.
Ill
Article II, section 7, of the Colorado Constitution provides in relevant part that “[t]he people shall be secure in their persons, papers, homes and effects, from unreasonable searches and seizures.” Although article II, section 7, is almost identical to the fourth amendment of the United States Constitution, we have held that the Colorado Constitution’s search and seizure provision provides greater protection than does the fourth amendment.
As the amicus curiae Colorado Criminal Defense Bar has pointed out, we have previously noted that “[sjeveral times we have determined that the Colorado proscription against unreasonable searches and seizures protects a greater range of privacy interests than does its federal counterpart,” Oates,
Accordingly, when we have been confronted with the question of the reasonableness of seizures that are substantially less intrusive than arrests, we have, as the United States Supreme Court has, balanced the competing interests of the state in accomplishing its legitimate goals and of the individual in the inviolateness of his or her person. See, e.g., People v. Savage,
Neither the defendant nor amici curiae have suggested any means other than by balancing the interests of the state and motorists by which we are to determine the reasonableness of the checkpoint stops. In Exotic Coins, Inc. v. Beacom,
We can find no basis in checkpoint-stop cases for concluding that “reasonableness” under article II, section 7, should be determined by a procedure other than balancing the interests of the state and the motorists, and determining whether the checkpoint stop in question reasonably advances the state’s interests.
The judgment of the district court is reversed, and this case is remanded to the district court for further proceedings consistent with this opinion.
Notes
. The People petitioned for certiorari pursuant to § 13-6-310, 6A C.R.S. (1987), and we granted certiorari pursuant to C.A.R. 49.
. E.g., Dunaway v. New York,
. The Court noted that detention of particular motorists for field sobriety testing may require satisfaction of an "individualized suspicion standard."
. No one can seriously dispute the magnitude of the drunken driving problem or the States’ interest in eradicating it. Media reports of alcohol-related death and mutilation on the Nation’s roads are legion. The anecdotal is confirmed by the statistical. "Drunk drivers cause an annual death toll of over 25,000 and in the same time span cause nearly one million personal injuries and more than five billion dollars in property damage." .... For decades, this Court has “repeatedly lamented the tragedy.”
. We recognize that in Sitz the Court was concerned with the question whether Michigan’s checkpoint system was generally valid under the fourth amendment whereas in this case we are confronted with a narrower issue — whether the defendant’s fourth amendment rights were violated. However, it is neither practical nor likely to be profitable to attempt to distinguish between the validity of the state patrol’s checkpoint system generally and the state patrol’s seizure of the defendant specifically. The remedy the defendant sought, and obtained, from the trial court was the suppression of evidence obtained against him as a result of the checkpoint seizure. Because the exclusionary rule is designed primarily to deter unlawful police conduct, e.g., United States v. Calandra,
. As in Sitz, no allegation has been raised that any state patrol officer subjected any person to unreasonable treatment, which may be subjected to post-stop judicial review. Sitz,
. Although the sobriety checkpoint was ultimately located at the intersection of Highway 14 and County Road 12, a state patrol sergeant had
attempted to research and establish D.U.I. arrests and D.U.I. involved data for Jackson [County Road] 12 and [County Road] 18 in order to hold a sobriety checkpoint on these roads the weekend of July 4, 1986.
The data is extremely limited due to the small amount of time a trooper has been stationed in the area. I have had to rely on Jackson County Sheriff's Office for a limited amount of information on D.U.I arrests they have made and mostly cold accident reports they have taken.
Jackson County Sheriff's Office records indicate D.U.I. arrests on [County Road] 12 on June 13, 1984 at [3:45 p.m.] and July 28, 1984 at [2:50 p.m.]. Accidents involving drinking drivers reveal one on June 13, 1984 at [3:45 p.m.]. On [County Road] 18, one accident involving a drinking driver occurred on August 11, 1984 at [7:30 p.m.] and one on August 5, 1984 at [3:00 p.m.].
The most important statistic is that on May 4, 1986 at [6:00 a.m.] and on May 17, 1986 at [12:10 a.m.], there were drinking driver accidents on [County Road] 18. On May 24, 1986 at [7:15 p.m.] there was one D.U.I. accident on [County Road] 12.
Although there is limited data for the location, common sense and experience of Sheriff's deputies and Grand County troopers confirm numerous drinking drivers commuting on this road between Walden and recreational sites at Lake John and Delanney Buttes Lakes on holiday weekends.
. The parlies dispute whether our decisions in People v. Benner,
. Numerous courts in other states have similarly upheld the constitutionality of sobriety checkpoints by similarly balancing the competing interests of the state and individual under their state constitutions, see, e.g., Ingersoll v. Palmer,
. We find no merit in the defendant’s arguments that the state patrol conducted a “search” violative of article II, section 7, of the Colorado Constitution. As we stated in People v. Carlson,
Dissenting Opinion
dissenting:
I dissent. Although the United States Supreme Court in Michigan Department of State Police v. Sitz, — U.S. -,
I.
In Sitz, the United States Supreme Court considered whether Michigan’s use of a highway sobriety checkpoint program violated the Search and Seizure Clause of the United States Constitution. In upholding the program, the Court acknowledged that a constitutional seizure occurs when a motorist is stopped at a checkpoint and subjected to preliminary questioning and observation by checkpoint officers,
This court, of course, is obligated to follow the Sitz decision as a matter of federal constitutional law. Nonetheless, the Sitz holding is remarkable for its failure to acknowledge the long-standing search and seizure principle, first enunciated in Terry v. Ohio,
Prior to Sitz, the only case upholding a suspicionless seizure of a motorist for temporary investigation was United States v. Martinez-Fuerte,
As Justice Stevens emphasized in his dissenting opinion in Sitz, there is a constitutionally significant difference between a routine stop at a permanent and clearly posted immigration checkpoint and a temporary highway sobriety checkpoint which the motorist encounters by surprise. “A motorist with advance notice of the location of a permanent checkpoint has an opportunity to avoid the search entirely, or at least prepare for, and limit, the intrusion on her privacy.”
A check for a driver’s license, or for identification papers at an immigration checkpoint, is far more easily standardized than is a search for evidence of intoxication. [An] officer who questions a motorist at a sobriety checkpoint has virtually unlimited discretion to detain the driver on the basis of the slightest suspicion. A ruddy complexion, an unbuttoned shirt, bloodshot eyes or a speech impediment may suffice to prolong the detention. Any driver who had just consumed a glass of beer, or even a sip of wine, would almost certainly have the burden of demonstrating to the officer that her driving ability was not impaired.
Id. at 2493. Finally, many of the stops at permanent immigration checkpoints occur during daylight hours, while the sobriety checkpoints are often operated at night. Id. A seizure of the motorist, followed by interrogation and even a cursory search at night, is clearly “more offensive than a daytime stop that is almost as routine as going through a toll gate.” Id. These fears are not the sole concern of the guilty, for “[t]o be law abiding is not necessarily to be spotless” and “what begins mildly may by happenstance turn severe.” Id.
Because the Michigan program was patterned after an older program in Maryland, the trial judge gave special attention to that State’s experience. Over a period of several years, Maryland operated 125 checkpoints; of the 41,000 motorists passing through those checkpoints, only 143 persons (0.3%) were arrested. The number of man-hours devoted to these operations is not in the record, but it seems inconceivable that a higher arrest rate could not have been achieved by more conventional means. Yet, even if the 143 checkpoint arrests were assumed to involve a net increase in the number of drunk driving arrests per year, the figure would still be insignificant by comparison to the 71,000 such arrests made by Michigan State Police without checkpoints in 1984 alone....
Any relationship between sobriety checkpoints and an actual reduction in highway fatalities is even less substantial than the minimal impact on arrest rates. As the Michigan Court of Appeals pointed out, “Maryland has conducted a study comparing traffic statistics between a county using checkpoints and a control county. The results of the study showed that alcohol-related accidents in the checkpoint county decreased by ten percent, whereas the control county saw an eleven percent decrease; and while fatal accidents in the control county fell from sixteen to three, fatal accidents in the checkpoint county actually doubled from the prior year.”
Id. at 2491-92 (footnotes and citations omitted). Similar observations have been made by state courts in concluding that sobriety checkpoint programs have not advanced the public interest in curbing drunken driving in a manner that justifies the accompanying intrusion into personal privacy and security. E.g., State v. Henderson,
II.
Article II, section 7 of the Colorado Constitution states that the people shall be secure in their “persons” and “effects” from unreasonable searches and seizures. Although this constitutional provision is similar in text to the Fourth Amendment, we have interpreted the Colorado Constitution in a manner more protective of personal privacy and security than the United States Supreme Court has been willing to recognize under the United States Constitution. E.g. People v. Oates,
The liberty interests of Colorado citizens find their source not only in the federal constitutional and statutory law, but also in state constitutional jurisprudence and the
The “balancing” test adopted by the majority in this case is at odds with longstanding principles of Colorado search and seizure jurisprudence. We have held in countless cases that before an individual may be seized for a temporary investigation, three conditions must exist: (1) the law enforcement officer effecting the seizure must have a specific and articulable basis in fact for suspecting that the person has engaged in criminal activity, is presently committing a crime, or is about to do so; (2) the purpose of the temporary seizure must be reasonable; and (3) the scope and character of the seizure must be reasonably related to its purpose. E.g., People v. Wilson,
Although the three-part test for a temporary or investigative seizure involves a balancing of the gravity of the public interest and the severity of the intrusion, the balancing or weighing aspect of the analysis is only part of the inquiry. The “balancing” factor, standing alone and devoid of the core component of reasonable individualized suspicion, is simply inadequate to support a temporary seizure under Colorado constitutional jurisprudence. See, e.g., Ratcliff,
Colorado statutory law also recognizes a need for reasonable individualized suspicion before a temporary seizure of the person may be effected. § 16-3-103(1), 8A C.R.S. (1986), states:
A peace officer may stop any person who he reasonably suspects is committing, has committed, or is about to commit a crime and may require him to give his name and address, identification if available, and an explanation of his actions.
(Emphasis added). Although on July 5, 1986, the day on which the defendant was subjected to the highway sobriety checkpoint, Colorado statutory law provided that any licensee “shall have his driver’s license in his immediate possession at all times when operating a motor vehicle, and shall display the same upon demand by any [law enforcement] officer,” § 42-2-113, 17 C.R.S. (1984), we held in People v. McPherson,
We do not believe that the legislature intended the statute to confer upon a police officer unlimited discretionary authority to stop any car at any time for any reason as long as he asked contemporaneously for display bf a driver’s license. A construction of the statute which would give to police officers such carte blanche authority would be inconsistent with section 16-3-103, C.R.S.1973, which specifically limits an officer’s authority to stop persons for investigation in the absence of probable cause to arrest. The clear intent of section 42-2-113 is simply to permit the officer to demand the license of the driver whose vehicle has been stopped for an otherwise proper purpose.
191 Colo, at 84,
The constitutional jurisprudence and statutory law of Colorado reflect values, standards, and practices that are irreconcilable with the judicial legitimatizing of sus-picionless temporary seizures of motorists solely on the basis of balancing the gravity of the public interest against the severity of the intrusion associated with the seizure. The majority’s rejection of a reasonable individualized suspicion component as a necessary condition for a temporary seizure of the person under the Colorado Constitution results in subjecting all persons to the risk of governmental intrusions that, in my view, are antithetical to the precious “right to be let alone” contemplated by article II, section 7 of the Colorado Constitution. By adopting the “balancing” test in Sitz and engrafting that test upon the Colorado Constitution, the majority ignores the uniqueness and independence of our own constitution and denigrates the Colorado Search and Seizure Clause to an insignificant redundancy.
III.
The express purpose of the sobriety checkpoint program in this case was to detect and apprehend motorists who were operating their vehicles while intoxicated or under the influence of alcohol. The Operational Procedures Bulletin promulgated by the Chief of the Colorado State Patrol directed the checkpoint officers to stop each vehicle, approach the motorist, state that the purpose of the stop was to determine the sobriety of the driver, and to ask the driver for his or her license. The officers were directed to look for evidence of alcohol impairment, and only if no such evidence was found was the motorist to be directed to proceed on his or her way. According to the operational procedures, if the checkpoint officer observed an “odor of alcoholic beverage about the driver, slurred speech, flushed appearance, disorderly or unusual conduct, visual disorders and/or lack of muscular coordination,” and if the officer reasonably believed that the motorist was under the influence of alcohol, the officer was then required to request the driver to perform certain “psychomotor coordination tests and/or submit to a chemical test of either his blood or breath.” Although general questioning with respect to a driver’s license and the associated observation of the motorist’s demeanor and speech do not involve an intrusive search for personal characteristics hidden from public view, see Carlson,
The operational procedures provided for publication of the dates on which sobriety checkpoints would be used, but the exact location and times of the checkpoints were to be kept confidential. The motorist approaching the checkpoint, therefore, would have no advance notice of any option other than to submit to the temporary seizure of his or her person for the associated questioning and observation by checkpoint officers. Moreover, even if some preliminary
Although the operational procedures stated that no action would be taken against a motorist who turned around or turned off the highway to avoid the sobriety checkpoint unless “a specific action other than merely turning around would justify pursuit,” it requires no great leap of imagination to realize that a motorist’s act of turning around or off the highway would only draw further attention to the police with the resulting risk of an arbitrary exercise of discretion that might well result in a more intensive intrusion into the motorist’s personal privacy and security. Indeed, if the facts of this case demonstrate anything, they quite clearly show that the sobriety checkpoint program places a motorist at the unfettered discretion of the checkpoint officers. When the defendant approached the checkpoint, he requested permission to make a right turn at the intersection to avoid the checkpoint examination. The checkpoint officer, however, denied the defendant’s request and directed him to proceed to the parking area, which the defendant did. Notwithstanding the fact that the guidelines provided the motorist with the right to avoid the sobriety checkpoint program by turning around or off the highway, and notwithstanding the further fact that the checkpoint officer observed nothing at this point in time that would justify either pursuit or further detention of the defendant, the defendant was nonetheless denied his right under the guidelines to avoid the sobriety checkpoint and was required instead to submit to the checkpoint examination. These facts alone, in my view, render the seizure of the defendant in this case constitutionally unreasonable.
Lastly, irrespective of the majority’s rejection of the reasonable individualized suspicion requirement for limited intrusions into personal privacy and security under the Colorado Constitution, I fail to see how the balancing process employed by the majority somehow weighs more heavily in favor of the state’s interests rather than the motorist’s right to personal privacy and security. The evidence shows that during the two and one-half hour period from 4:30 p.m. to 7:00 p.m. on July 6, 1986, the officers stopped 233 vehicles at the sobriety checkpoint without, however, arresting a single motorist for driving under the influence of, or while the motorist’s ability was impaired by, intoxicating liquor. The majority seems to find solace in the fact that “the announcement and establishment of a sobriety checkpoint undoubtedly had some effect on advancing the state’s interest in preventing drunken driving.” Maj. op. at 489. I believe Justice Stevens’ observations in his dissenting opinion in Sitz cogently put to, rest the notion that dramatizing the public interest in the prevention of alcohol-related accidents somehow tilts the constitutional balance in favor of the checkpoint program. After noting that the shock value of the program may be its most effective feature, he echoed Justice Scalia’s dissenting comments in National Treasury Employees Union v. Von Raab,
Even symbolism for so worthy a cause as the abolition or deterrence of drunken driving, in my view, cannot validate an otherwise unreasonable and unconstitutional seizure of the person. The traditional “roving patrol” techniques of policing our highways and roads, the abolition of plea bargaining in drunken driving cases, and stringent administrative revocation or suspension of licenses provide effective means, consistent with constitutional processes, for combatting the threat to public safety caused by the drunken driver. Unfortunately, this court “is transfixed,” as was the United States Supreme Court in Sitz, “by the wrong symbol — the illusory prospect of punishing countless intoxicated motorists — when it should keep its eyes on the road plainly marked by the Constitution,” Sitz,
Even assuming that roadblocks may have some deterrent effect, we believe that it is purchased at too high a price. Doubtless other devices may also increase the effectiveness of law enforcement, including punishment without trial, repealing of the privilege against self-incrimination, dispensing with the right to confrontation of witnesses, and elimination of trial by jury. Such techniques, however, would diminish the rights of all in order to secure the punishment of a few.
I would affirm the suppression ruling on the basis that the evidence of the defendant’s act of driving while his license had been denied was obtained as the direct result of an unconstitutional seizure of his person in violation of article II, section 7 of the Colorado Constitution.
. Subsequent to Martinez-Fuerte, the Court in National Treasury Employees Union v. Von Raab,
. In Henderson, the Idaho Supreme Court invalidated a DUI roadblock, authorized by the Boise Police Department, under the Idaho constitutional prohibition against unreasonable searches and seizures. The court concluded that DUI roadblocks were not an efficient means of detecting or deterring drunken driving, especially in view of the Boise Chief of Police’s testimony that "the same number of officers on patrol would make more DUI arrests than the same number of officers engaged in a roadblock."
In Koppel, the New Hampshire Supreme Court invalidated a drunken driving roadblock program under the New Hampshire constitution because the roadblock stops required no individualized suspicion and the state failed to demonstrate that the roadblocks produced sufficient public benefit to outweigh their intrusion on individual rights. In the course of its opinion the court observed as follows:
The record indicates that 47 roadblocks were set up on 21 weekend nights between April 29, 1984, and October 20, 1984. A total of 1,680 vehicles were stopped, resulting in only 18 DWI arrests. During roughly the same six months, the Concord police made 175 DWI arrests by traditional methods; i.e., through the use of roving patrols.
In Mesiani, the Washington Supreme Court invalidated Seattle's sobriety checkpoint program under the Washington Constitution. In the course of its opinion the court noted that the City of Seattle "has failed to demonstrate the need for sobriety checkpoints or that less intrusive alternatives could not achieve most of the constitutionally permissible benefits sought, such as the addition of more officers to its special enforcement unit.”
