The State of North Dakota appealed from an order of the County Court for Mercer County granting Tom A. Wetzel’s motion to suppress evidence obtained during a vehicle safety inspection at a highway checkpoint. The State contends that its checkpoint and procedures for stopping oncoming vehicles were constitutionally permissible. We agree and reverse the county court’s suppression order.
On August 3, 1989, Trooper Ronald Stanley of the North Dakota Highway Patrol established a checkpoint on North Dakota highway 200 between Pick City and River-dale for the purpose of conducting routine vehicle safety inspections. Each trooper with the Highway Patrol is required to perform three hundred inspections per year. Tom Wetzel’s automobile was the sixteenth vehicle stopped at the checkpoint. After inspecting the safety features of the vehicle, Trooper Stanley asked Wetzel for his driver’s license. Wetzel failed to produce a license and it was eventually determined that his driving privileges were under suspension. Wetzel was charged with driving under suspension. See NDCC § 39-06-42.
Wetzel made a motion in the County Court for Mercer County to suppress all evidence obtained by Trooper Stanley resulting from the checkpoint stop. Wetzel claimed that Trooper Stanley exercised “unbridled discretion” in determining which vehicles to stop at the checkpoint thereby causing the stop to be unconstitutional under the Fourth Amendment of the United States Constitution and Article I, § 8 of the North Dakota Constitution. Additionally, Wetzel argued that Trooper Stаnley did not have any reasonable and articulable suspicion for stopping his automobile.
During the hearing on Wetzel’s motion to suppress, Trooper Stanley testified as to the procedures he used at the checkpoint. He stated that there was a department procedure regarding vehicle inspection sequence. That procedure, which he testified he utilized and dеscribed on the top of his Highway Patrol vehicle inspection form, was to stop a car, conduct an inspection, and then “stop the next available vehicle when safe.” 1 Not all oncoming cars were *117 inspected at the checkpoint and other automobiles were able to freely pass through the checkpoint while he was conducting an inspection on a stopped vehicle. Troopеr Stanley further testified that it was his decision to stop the next available vehicle and to determine when it was safe to do so. In this regard, he noted that if a group of five or six automobiles approached the checkpoint, he would not stand on the road to flag over a vehicle as it would not be safe for either himself or the traveling public. Trooper Stanley also testified as to the vehicle inspection procedures. Once a vehicle was stopped, he would inspect the automobile’s front headlights, front turn signals, rear turn signals, rear brakelights, windshield wipers, and horn. Examination of the driver’s license was also part of the routine check. All vehicles stopped were logged onto the vehicle inspection form which indicated whether the automobile had any defects, and whether any citations were issued. Finally, Trooper Stanley indicated that his checkpoint was visible by drivers for approximately two miles, that Wetzel’s automobile was traveling alone on the highway at the time it was stopped, and that he had no articulable and reasonable suspicion for stopping Wetzel’s vehicle other than for the fact that he was conducting a vеhicle safety inspection checkpoint.
After the suppression hearing, the trial court granted Wetzel’s motion to suppress, concluding that the State did not adequately meet its burden of establishing that Trooper Stanley acted without unconstrained discretion in selecting vehicles to stop. 2
The sole issue presented on appeal is whether the procedure utilized by Troopеr Stanley in stopping vehicles at the checkpoint was constitutionally impermissible because it provided him with unconstrained discretion over which vehicles to stop.
In
Delaware v. Prouse,
The Suprеme Court noted that the Fourth Amendment was implicated in these types of cases “because stopping an automobile and detaining its occupants consti
*118
tutes a ‘seizure’ ... even though the purpose of the stop is limited and the resulting detention quite brief.”
Prouse, supra,
In weighing the competing interests, the Supreme Court recognized that “States have a vital interest in ensuring that only those qualifiеd to do so are permitted to operate motor vehicles, that these vehicles are fit for safe operation, and hence the licensing, registration, and vehicle inspection requirements are being observed.”
Prouse, supra,
The overall effect of a purely random spot-check on the individual’s privacy interest, when weighed against the total disсretion of the police officer to conduct a spot-check, led the Court to hold that:
“[Ejxcept in those situations in which there is at least articulable and reasonable suspicion that a motorist is unlicensed or that an automobile is not registered, or that either the vehicle or an occupant is otherwise subject to seizure for violation of law, stopping an automobile and detaining the driver in order to check his driver’s license and the registration of the automobile are unreasonable under the Fourth Amendment. This holding does not preclude the State of Delaware or other States from developing methods for spot checks that involve less intrusion or that do not involve the unconstrained exercise of discretion. Questioning of all oncoming traffic at roadblock-type stops is one possible alternative. We hold only that persons in automobiles on public roadways may not for that reason alone have their travel and privacy interfered with at the unbridled discretion of police officers. [Emphasis added.] Prouse, supra,440 U.S. at 663 ,99 S.Ct. at 1401 ,59 L.Ed.2d at 673-74 .
Justice Blackmun, in his concurring opinion in Prouse, noted that the Court had merely furnished one possible alternative to curbing the unbridled discretion of officers in stopping vehicles when it suggеsted stopping all oncoming traffic. He explained:
“The roadblock stop for all traffic is given as an example. I necessarily assume that the Court’s reservation also includes other not purely random stops (such as every 10th car to pass a given point) that equate with, but are less intrusive than, a 100% roadblock stop.” [Emphasis added.] Prouse, supra,440 U.S. at 664 ,99 S.Ct. at 1401 ,59 L.Ed.2d at 674 .
It is clear that what disturbed the Court in
Prouse
was the patrolman’s unconstrained discretion in randomly stopping any car, at any time, and under any procedure he desired.
State v. Goehring,
The United States Supreme Court has not revisited this matter since Prouse, and while our Court has never had the opportunity to directly entertain whether a particular procedure for checkpoint stops is in conformity with Prouse, 3 other courts have considered a myriad of policies and procedures for systematically stopping vehicles at roаdside checkpoints. Courts have frequently upheld procedures in which officers have stopped all oncoming traffic at a checkpoint; 4 and procedures where officers have stopped vehicles in some predetermined numerical order, such as every fifth vehicle. 5 In a number of cases from state courts, procedures very similar to the ones used by Trooper Stanley were upheld as constitutional under the Fourth Amendment.
For example, in
State v. Goines,
With the aforementioned principles in mind, we turn to the vehicle safety checkpoint involved in the instant case. The State of North Dakota has a vital interest in ensuring that the vehicles on its roads are safe for operation, and that licensing requirements are being observed. Delaware v. Prouse, supra. When balancing this interest against the intrusiveness of Trooper Stanley’s checkpoint into Wetzel’s рrivacy rights, we believe that the checkpoint was “reasonable” under the Fourth Amendment. The checkpoint in this case was more like a roadblock, as opposed to the roving, random spot-check in Prouse, in the sense that it was fixed in position, had visible signs of the State’s police authority, and could be seen by oncoming traffic for approximately two miles thereby allowing automobile operators to observe other vehicles being stopped and making them much less likely to be frightened or annoyed by the State’s intrusion.
Additionally, we find that the procedure utilized for stopping vehicles at the checkpoint was sufficiently systematic to pass constitutional muster. As was previously mentioned, “[i]t is not necessary for [the] checkpoint to stop every car in order to be systematic but only for officers to be following some pattern that will minimize their discretion in choosing whether to stop a particular auto.” [Emphasis added.] 1 LaFave, Criminal Procedure, § 3.9 (1984). Here, Trooper Stanley had an established vehicle safety checkpoint along the highway. His pattern, which complied with Highway Patrol policy, was to stop an automobile, inspect it, and then “stop the next available vehicle when safe.”
We do not believe that the “when safe” condition permits the exercise of “unbridled discretion.” Rather, we assume that such a condition is, if not specifically contained therein, implied in any policy concerning roadblock or checkpoint stops, i.e., an officer is not required to stop vehicles pursuant to the policy when unsafe or, in the alternative, take the risk of invalidаting the stop because he does not rigidly adhere to the policy. In any event, Wetzel’s automobile was traveling alone when Trooper Stanley stopped it as the next available vehicle.
Courts in other jurisdictions have found nearly identical procedures for stopping vehicles to be systematic for purposes of *121 curbing officer discretion. Goines, supra; Shankle, supra; Estrada, supra. In short, when compared to the random, roving stop in Prouse, supra, where the officer simply “saw a car in the area,” “wаsn’t answering any complaints,” and just “decided to pull them off” for a license and registration inspection, the facts of the instant case illustrate that Trooper Stanley’s stop of Wetzel’s automobile wasn’t merely an act of unbridled whim, but was a part of a calculated pattern established for inspecting vehicles at a fixed checkpoint.
Because we find that the inspection сheckpoint in the instant case was both reasonable and systematic under the Fourth Amendment, we reverse the suppression order of the trial court.
Notes
. Trooper Stanley testified that the Highway Patrol’s procedure at such checkpoints was to "stop the next available vehicle when safe," and that he wrote the procedure down on the top of his vehicle inspection form. A written copy of the department's policy was not entered into evidence. However, the Highway Patrol’s procedure for motor vehicle inspection checkpoints can be found in Policy 3-7, North Dakota Highway Patrol Policy Manual, which states in relevant part:
"TITLE: MOTOR VEHICLE INSPECTION
[[Image here]]
“POLICY
[[Image here]]
"B. Motorists and officer safety will be of primary consideration when selecting a location, time period, or pattern of vehicles to be inspected.
"PROCEDURE
[[Image here]]
"D. Prior tо beginning the inspection of motor vehicles, officers will determine the order in which vehicles are to be inspected. For example; every vehicle, or every third, fifth, *117 or tenth vehicle, or in any other sequence that can be safely managed.
"E. If only one officer is conducting vehicle inspections, that officer shall inspect the next vehicle that approaches the оfficer’s inspection point after releasing the last vehicle inspected.
“F. In every instance and prior to beginning the inspection of motor vehicles, the order in which vehicles are to be inspected will be noted on top of SFN 3435 (NDHP Form 325). A separate SFN 3435 will be completed each time the order of inspection or the inspection site is changed.

While it is apparent that Trooper Stanley was following the procedure in subsection E of Policy 3-7, we will consider the stop of Wetzel’s automobile in light of Trooper Stanley’s interpretation and utilization of the policy as was expressed in his testimony.
. After concluding that the State did not adequately meet its burden, the trial court observed: "As a matter of fact, this Court has a great deal of difficulty defining as to what the burden should be or in the alternative as to the criteria that should be used by officers in conducting a vehicle safety check."
