OPINION
Efrain Estrada-Nava and Eric Colin were indicted on one count of possession of methamphetamine with intent to distribute, in violation of 21 U.S.C. § 841(a)(1). They moved in the district court to suppress the evidence on which the charge was based, claiming it was the fruit of an illegal stop and search. The district court denied the motion. Estrada-Nava and Colin then pled guilty to the charge. 1 We reverse and hold that the police officer who discovered the evidence did so only after he stopped Estrada-Nava and Colin’s car without reasonable suspicion, in violation of the Fourth Amendment. 2
BACKGROUND
On November 12, 1999, at approximately 2:05 a.m., Sergeant Thomas Carmichael observed a blue Honda traveling at 70 m.p.h. northbound in the right lane on Interstate 15. Carmichael first observed the Honda from his patrol car, which was positioned 75 yards behind it. He observed the car drift onto the solid white fog line on the far side of the right lane and watched the car’s wheels travel along the fog line for approximately ten seconds. The Honda then drifted to the left side of the right lane, signaled a lane change, and moved into the left lane. Carmichael next observed the car drift to the left side of the left lane where its left wheels traveled along the solid yellow line for approximately ten seconds. The car then returned to the center of the left lane, signaled a lane change, and moved into the right lane. Carmichael pulled the car over for possible violations of California Vehicle Code § 21658(a) (lane straddling) and California Vehicle Code § 23152(a) (driving under the influence).
Appellant Efrain Estrada-Nava (“Estrada-Nava”) was the driver of the car and appellant Eric Colin (“Colin”) was his passenger. When Carmichael advised Estrada-Nava of the reasons for stopping him and asked for his license and registration, he noticed that both Estrada-Nava and Colin were nervous and shaking. He also noticed that the glove compartment contained a bottle of air freshener and a radar detector, that there were only three keys on Estrada-Nava’s key ring, and that nei *442 ther Estrada-Nava nor Colin owned the Honda. Suspecting that the car might have been stolen, Carmichael separately-questioned Estrada-Nava and Colin about the ownership of the vehicle. On the basis of their slightly conflicting stories, their nervous appearances, and his own training and experience, Carmichael concluded they might be involved in drug trafficking. Estrada-Nava and Colin separately consented to a search of the Honda, which revealed marijuana and methamphetamine. 3
Colin filed a motion to suppress the narcotics evidence, in which Estrada-Nava joined, arguing that Carmichael illegally stopped the Honda and illegally detained the two of them thereafter. After an evi-dentiary hearing, the district court denied the motion, concluding that Carmichael had reasonable suspicion to stop the car and that the evidence therefore was legally obtained. Estrada-Nava and Colin appealed.
STANDARD OF REVIEW
We review
de novo
the district court’s determination of reasonable suspicion.
United States v. Arvizu,
DISCUSSION
The Fourth Amendment’s prohibition against unreasonable searches and seizures applies to investigatory traffic stops.
Arvizu,
A. Standing
To challenge their stop on Fourth Amendment grounds, Estrada-Nava and Colin must have a reasonable expectation of privacy in the Honda.
United States v. Dorais,
B. The Stop
Carmichael stopped Estrada-Nava and Colin for possible violations of California Vehicle Code section 21658(a) (lane straddling) and section 23152 (driving under the influence). We will address each of these potential violations in turn. Carmichael also thought that Estrada-Nava may have been fatigued. We will address this issue together with section 23152.
1. California Vehicle Code § 21658(a) (“lane straddling”)
Carmichael stopped Estrada-Nava and Colin in part for violating California’s “lane straddling” statute. The statute states:
Whenever any roadway has been divided into two or more clearly marked lanes for traffic in one direction, the following rules apply: (a) A vehicle shall be driven as nearly as practical entirely within a single lane and shall not be moved from the lane until such movement can be made with reasonable safety.
Cal. Veh.Code § 21658(a). Under the proper construction of this statute, Estrada-Nava and Colin’s conduct was not a violation.
When interpreting California Vehicle Code section 21658(a), we are bound to follow the decisions of the California Supreme Court.
Paulson v. City of San Diego,
The California Supreme Court has not issued an opinion directly addressing section 21658(a). The Los Angeles Superior Court, Appellate Department, however, interpreted this statute in
People v. Butler,
It is our view that section 21658, subdivision (a) simply states two affirmative duties placed upon the operator of a motor vehicle. One of these is to drive as nearly as practicable entirely within one lane. A separate duty is not to move from that lane until the movement can be made with reasonable safety.
Id. Although the driver in Butler made no unsafe lane changes, the court held that he failed to drive within a single lane, thus violating section 21658(a). Id.
The California Supreme Court has cited Butler with approval for the proposition that:
The inadvertent use of ‘and’ where the purpose or intent of a statute seems clearly to require ‘or’ is a familiar example of a drafting error which may properly be rectified by judicial construction.
See People v. Skinner,
Even if we interpret section 21658(a) to impose two separate duties on drivers—to stay within a single lane and to make safe lane changes—we conclude that Estrada-Nava and Colin did not violate the statute.
Estrada-Nava and Colin’s car touched for approximately ten seconds, but did not cross, the fog line and the solid yellow-painted line. The district court concluded on the basis of these facts that Carmichael had reasonable suspicion to stop Estrada-Nava and Colin for lane straddling because “[a] common sense definition of lane straddling ... includes a situation in which a vehicle’s wheels rest on the marking line.” We disagree, and conclude that based on the “totality of the circumstances,” Carmichael lacked the requisite reasonable suspicion to stop Estrada-Nava and Colin for lane straddling.
As the district court pointed out, neither section 21658(a) nor California case law specifies what is meant by “drive as nearly as practical entirely within a single lane.” It therefore is unclear under California law whether a car’s wheels must
cross over
a line for there to be a violation of lane straddling. Courts in other states, however, that have interpreted statutes similar to, if not the same as, section 21658(a) have held that touching the line is not enough to constitute lane straddling.
See, e.g., United States v. Gregory,
Even if we assume, as the district court did, that “if the wheels were on the line, then that part of the vehicle that extends beyond the wheels was over the line and the car was traveling in two lanes,” we still conclude that there was not reasonable suspicion to stop Estrada-Nava and Colin for a violation of section 21658(a). Touching a dividing line, even if a small portion of the body of the car veers into a neighboring lane, satisfies the statute’s requirement that a driver drive as “nearly as practical entirely within a single lane.” Cal. Veh.Code § 21658(a) (emphasis added); see also Crooks v. State, 710 So.2d *445 1041, 1043 (Fla.Dist.Ct.App.1998) (“Because the record does not establish how far into the righthand emergency lane [defendant] drove on any of three occasions, there is no basis to state that he was outside the ‘practicable’ lane.” (emphasis added)). The Honda touched the lines only twice, both times before making safe lane changes. It is reasonable that a driver with no ears abreast of him might veer slightly within his lane or over the lane line in the course of making a lane change to ensure that it is safe to do so.
In sum, we conclude that the facts, taken together, support the conclusion that Carmichael lacked probable cause to stop Estrada-Nava and Colin for lane straddling.
2. California Vehicle Code § 23152 (driving under the influence)
At the evidentiary hearing on the motion to suppress, Carmichael testified that he stopped Estrada-Nava and Colin in part for a “possible” violation of driving under the influence. 4 He described Estrada-Nava’s “unusual” driving pattern as follows:
Most people who travel the highway travel the main portion of the lane which is pretty much the center of the lane. To travel the extreme right for an extended period of time and then travel to the extreme left portion of the lane and then make the lane change and then travel again to the extreme left portion of that lane, those are irregular driving patterns.
The district court concluded on the basis of Carmichael’s testimony that “he was reasonable in concluding ... that the mere fact Estrada-Nava signaled as he moved back and forth across the highway did not neutralize the erratic pattern of driving he observed.” We disagree.
Although we recognize that in some cases evidence of weaving might be indicative of driving under the influence, we disagree that the evidence in this case was sufficient for Carmichael to harbor a reasonable suspicion that Estrada-Nava was driving under the influence, thus justifying the stop. Carmichael testified that he observed Estrada-Nava and Colin’s vehicle for 35-45 seconds before pulling it over, and that during this time, Estrada-Nava drove within the speed limit and properly activated his turn signals before making lane changes. Carmichael thought Estrada-Nava was “possibly” driving under the influence because the car’s wheels touched the fog line on the right side of the right lane for 10 seconds and then, about 5-10 seconds later, touched the yellow line on the far left of the left lane for another 10 seconds.
In
People v. Perez,
an officer with training and experience in handling cases involving driving under the influence observed a driver weave within his lane (two feet in each direction) for approximately three-quarters of a mile. The court considered as a matter of first impression in California whether an officer “may lawfully detain a driver[on the basis of driving under the influence] who has been observed to be weaving
within his lane.”
Here, Estrada-Nava and Colin did not demonstrate “pronounced weaving” of up to two feet in either direction, or weave for a “substantial distance.” In fact, the only “suspicious” behavior Carmichael observed was Estrada-Nava and Colin’s car touching the right fog line and the center yellow line each for 10 seconds, after legitimate lane changes. This is hardly “pronounced weaving.”
See State v. Caron,
[I]f failure to follow a perfect vector down the highway or keeping one’s eyes on the road were sufficient reasons to suspect a person of driving while impaired, a substantial portion of the public would be subject each day to an invasion of their privacy.
United States v. Lyons,
As a final note, we find it curious that Carmichael did not conduct a sobriety field test or ask Estrada-Nava if he had been drinking when he stopped the car. This further convinces us that Carmichael did not harbor reasonable suspicion that Estrada-Nava was driving under the influence.
See United States v. Gregory,
In sum, we conclude Carmichael did not have reasonable suspicion to stop Estrada-Nava and Colin based on lane straddling or driving under the influence. As a result, the methamphetamine he seized through the search of their vehicle should have been suppressed.
See United States v. Twilley,
C. Ex Parte Application for Out-of-District Subpoena
Estrada-Nava and Colin also appeal the district court’s denial of their
ex parte
application for issuance of an out-of-district subpoena duces tecum pursuant to Federal Rule of Criminal Procedure 17(c). In their respective plea agreements, Estrada-Nava and Colin reserved only their right to seek review of the district court’s denial of the motion to suppress. They did not reserve the right to appeal “any other determination or issue,” including the district court’s denial of their
ex parte
application for a subpoena duces tecum. As a result, Estrada-Nava and Colin have waived this issue on appeal, and we decline to rule on it.
See United States v. Chon,
CONCLUSION
Because we hold that Carmichael did not have reasonable suspicion to stop Estrada-Nava and Colin and that the motion to suppress therefore should have been granted, we need not address the constitutionality of Estrada-Nava’s and Colin’s subsequent detention.
REVERSED and REMANDED.
Notes
. Estrada-Nava and Colin entered a conditional plea agreement that preserved their right to appeal the district court’s ruling on their motion to suppress.
. Because we hold that the police officer lacked reasonable suspicion to stop Estrada-Nava and Colin, in violation of the Fourth Amendment, we decline to reach the issue of whether the stop was motivated by a programmatic aim to enforce drug and weapons laws.
. We have cited only the facts relevant to our disposition of the case.
. Carmichael also testified that he thought Estrada-Nava was possibly fatigued or ill.
. The court noted that it has been clearly established in California that "weaving from one lane to another justifies an investigatory stop.” Id.
. There were no intervening events that purged the illegal taint.
