MOSK, J.Defendant appeals from a conviction of possession of a restricted dangerous drug. (Health & Saf. Code, § 11910.)
Approximately 3 a.m. on September 14, 1970, two police officers in a patrol car observed the automobile of defendant, a college student returning from a vacation trip to the Colorado River, proceed through *657an intersection against a red signal. They undertook pursuit, but did not activate their siren or warning light or otherwise identify themselves. When they were approximately 150 yards behind defendant’s vehicle they observed it pull over to the curb and stop. As they approached, they saw defendant lying across the front seat with his head toward the passenger’s side. Defendant then sat up.
At the officers’ request defendant alighted from the vehicle and produced his driver’s license for examination by one officer. Meanwhile the other officer physically entered the vehicle from the driver’s side, leaned across the front seat to unlock the passenger’s door from the inside, then exited and walked around the car, opened the door on the passenger’s side, and searched the front floorboard with a flashlight. The officer testified that during that search he discovered a small white tablet he believed to be benzedrine. Defendant was placed under arrest for possession of a dangerous drug and his pockets were searched, revealing a cellophane package of six or seven similar tablets. Chemical analysis showed the tablets contained amphetamine.
In People v. Superior Court (Kiefer) (1970) 3 Cal.3d 807 [91 Cal.Rptr. 729, 478 P.2d 449, 45 A.L.R.3d 559], and Gallik v. Superior Court (1971) 5 Cal.3d 855 [97 Cal.Rptr. 693, 489 P.2d 573], we recently reaffirmed the principle that conduct of an automobile occupant reasonably susceptible of innocent interpretation does not constitute probable cause to search the vehicle incident to citation for a traffic violation. As we explained in Kiefer (at p. 829), to allow a random search in ordinary traffic violation cases would constitute an intolerable and unreasonable intrusion into the privacy of the vast majority of peaceable citizens who travel by automobile. A search is therefore constitutionally authorized only if the conduct would induce a reasonable man to believe that contraband or weapons are being concealed. (Accord, United States v. Robinson (D.C.Cir. 1972) 471 F.2d 1082.)
The Attorney General suggests three facts in the record that assertedly render the total atmosphere of this case distinguishable from Kiefer and Gallik. First, defendant pulled his vehicle to the curb on his own accord instead of being stopped by the officers. But halting a vehicle voluntarily is not suspicious conduct. On the contrary, under these circumstances the act tends to remove suspicion from the defendant, since it suggests his behavior was motivated by something other than a consciousness of police pursuit. At the time he stopped his vehicle, defendant apparently was unaware of the proximity of law enforcement officers; to him the patrol car appeared to be nothing more than a pair of headlights in his rearview mirror. We anticipated this identical situation in Kiefer, *658when we pointed out if the defendant had not seen the police or did not recognize the vehicle following him to be a police car, “any movement he made would be irrelevant.” (3 Cal.3d at p. 821.)
Next the People stress that defendant was observed to be lying down, while the automobile occupants in Kiefer and Gallik were merely bending over. The distinction seems insignificant. Although a prone position in an automobile is perhaps less common than bending over, it is not less susceptible of innocent interpretation. Since the facts suggest defendant was unaware of the impending confrontation with the police, no reason exists to believe he was attempting concealment of any object.1 He might, as he testified, have been adjusting a loose connection in the fuse box under the dashboard. Even if, despite the absence of siren or red light in the darkness of night, the officers could reasonably have believed defendant was somehow aware of their silent pursuit, they would have had little cause to suspect his purpose was anything but innocent, such as reaching for his driver’s license or registration in the glove compartment on the far side of the car. Thus defendant’s simple act of reclining across the front seat did not furnish probable cause for the search. (See generally Kiefer, at pp. 821-823 of 3 Cal.3d.)
The third asserted distinction is that the confrontation in this case took place at night, while those in Kiefer and Gallik occurred during the day. But we have already explained the minimal importance of the nighttime factor: as we stated in Kiefer (at p. 825), “the fact that it is night when the police appear is not ‘conduct’ of the motorist ‘in response to’ the officer’s signal. The significance of this fact should therefore be appraised with caution; it does not, without more, transform an innocent gesture into a culpable one furnishing probable cause to search.”
This case is squarely controlled by Kiefer and Gallik. For the reasons there stated, the court committed prejudicial error in admitting the evidence found in the search of defendant’s car.
The judgment is reversed.
Wright, C. J., Tobriner, J., and Sullivan, J., concurred.
The rationalization that the officers could search the vehicle for hidden weapons in the interest of their own safety does not withstand analysis. Neither officer in his testimony articulated any fears for his safety from this college student-traffic violator, and their conduct indicated no such apprehension. One officer directed the defendant to “step to the rear of the car,” where he examined the driver’s license and kept the defendant under surveillance. With the defendant thus physically unable to reach a weapon in the car had there been any—there were none; only water skis on the seat—the second officer entered the vehicle and conducted the search which produced one white tablet.
