The State appeals the district court’s determination that there was no justifiable basis for the stop that led to defendant’s arrest for driving while intoxicated. We reverse.
At approximately two-thirty in the morning of May 22,1999, a state trooper observed defendant operating a vehicle close to or on the centerline of a paved highway. The officer then observed defendant’s vehicle swerve to the right and then eventually turn into a driveway. The officer followed defendant after he pulled back onto the highway and drove first onto one dirt road, and then another. Defendant drove down the center of these dirt roads. At some point, the officer stopped defendant for the prior erratic operation and for failing to drive on the right. Eventually, defendant was processed and charged with driving while intoxicated, third offense.
Following a hearing, the district court granted defendant’s motion to suppress, ruling that the officer had no reasonable and articulable basis for stopping defendant. The court noted that it is the custom of many Vermonters to drive in the center of dirt roads until and unless they see oncoming traffic. On appeal, the State argues that the officer’s stop was justified based on his observation of defendant violating state law requiring motorists to drive on the right side of roads. See 23 VS.A. § 1031 (driving to right).
Except for circumstances that did not exist in this case, § 1031(a) requires persons to drive on the right half of roadways of sufficient width. The undisputed testimony of the officer was that defendant was driving left of the center of the road, and that although the road was wide enough for two cars to pass, it was questionable whether an oncoming car could have passed by defendant because of his position in the center of the road. Given defendant’s failure to stay to the right, as required by statute, the officer was justified in stopping him. See State v. Welch, *547162 Vt. 635, 636, 650 A.2d 516, 517 (1994) (mem.) (reasonable and articulable suspicion of wrongdoing is necessary for police officer to stop motor vehicle being operated on highway). Notwithstanding defendant’s argument to the contrary, State v. Kirby, 143 Vt. 369, 465 A.2d 1369 (1983), is on point. In that case, just as here, the evidence demonstrated that the unpaved road was wide enough for two cars to pass in opposite directions, but that the defendant had positioned his car such that safe passage was compromised. See id. at 371, 465 A.2d at 1370.
