Opinion
HOPPER, J.
On Mаy 6, 1977, California Highway Patrol Officer John Davis observed petitioner’s vehicle traveling southbound on Highway 99 in Kern County. The automobile was in the fast lane and was weaving erratically in and out of the unpaved center divider. Officer Davis signaled the automobile over, and, after it stopped, asked petitioner to get out. No other passengers were in the car.
Officer Davis and petitioner went to the rear of petitioner’s car where petitioner was asked for his driver’s license. Officer Davis did not request petitioner to produce his registration slip. Petitioner appeared to be intoxicated and was unable to perform field sobriety tests. Thereafter, he was placed under arrest for driving undеr the influence of intoxicating liquor, was handcuffed, and placed in Officer Davis’ patrol car. When asked what was to be done with his car, petitioner indicated that he wanted the car to remain where it was—on the dirt shoulder of the highway. He also indicated that he did not have anyone to pick it up.
*365 Officer Davis then called a tow truck to haul the car away, despite the fact that it was legally parked and would remain so for four hours.
After calling the tow truck, Officer Davis approached petitioner’s car, turned off its engine, and began an automobile contents inventory, beginning with a search for the car registration. At no time did Officer Davis ever request petitioner to produce the registration. In checking the glove compartment, he found shotgun shells and a box of .38 caliber ammunition, but no registration slip. He then looked down and observed a black taped handle to what appeared to be a blackjack or billy club protruding out from under the front seat. After Officer Davis examined the object, pulled it out, and discovered it to be an innocuous garden tool, he looked under the seat and saw a .38 caliber revolver in a brown holster. Officer Davis sеized the weapon after a check revealed it to be stolen.
Officer Davis ultimately located the registration slip on the sun visor, filled out a storage report, and had the car towed away.
Officer Davis testified that he seаrched the glove compartment only to secure the registration slip. Petitioner was ultimately charged with violations of Penal Code section 12025 (ex-felon in possession of a concealed firearm) and Vehicle Code sеction 23102, subdivision (a) (driving under the influence of intoxicating liquor). At the preliminary hearing petitioner moved to suppress the evidence of the gun seized from the automobile and the testimony of the officer (Pen. Code, § 1538.5). The motion was denied. That motion was renewed in the superior court along with a motion to dismiss under Penal Code section 995. At the hearing on the motions the matter was submitted on the preliminary hearing transcript. Both motions were denied. Petitioner seeks a writ of mandate ordering the superior court to suppress the evidence of the seized gun and testimony re the gun and to dismiss. We grant the writ.
Since the presence of liquor is corroborating evidence, as an incident to an arrest for driving under the influence of intoxicating liquor, an officer can conduct a reasonable search in the interior of the vehicle in which the offender is apprehended for liquor containers

567]). However, the People did not seek to sustain the sеizure in this case on the basis of it being incident to an arrest. We cannot, of course, nor can the People “ . . . invoke a new theory based upon the premise that the arresting officer in making the search
could
have acted reasonably upon a particular ground when the prosecution has failed to make a factual showing at the original hearing that the arresting officer did act upon that ground.”

Superior Court
(1972)
The People contend that the writ should be denied becаuse the “plain sight” rule applies. Observation by an officer from a place where he had a right to be does not violate the constitutional limits

First, the People assert the officer had the right to enter the vehicle to shut off the engine which had been left running by the petitioner. We agree that Officer Davis had the right to enter the vehicle for that purpose. The unoccupied vehicle was standing on the dirt shoulder of a well-traveled highway with its engine running while its driver was in custody. This definitely presented a situation justifying entry into the vehicle to turn off the engine. However, there is no evidenсe to show that the officer had a plain view of the gun when he entered for the purpose of turning off the key—in fact, it appears that discovery was made later after the completion of the search of the glove сompartment.
Second, the People contend that Officer Davis entered the vehicle in preparation to removing the vehicle from the highway. However, this is a limited right under
Mozzetti
v.
Superior Court
(1971)
Lastly, the People contend Officer Davis had a right to enter the vehicle to obtain the registration certificate. We hold that an officer may enter a vеhicle to check on the registration in limited circumstances. We agree with the People that “numerous California cases hold that Vehicle Code section 2805 3 authorizes an officer under reasonable circumstances to enter a vehicle for the purpose of investigating its title or registration.” The purpose of Vehicle Code section 2805 is to enforce the registration laws and to check on stolen vehicles and parts. Nevertheless, we bеlieve that to balance such purposes and the right to privacy (see Cal. Const., art. I, § 13, and art. I, § 1), when the vehicle is occupied, the officer-must first inquire as to the location of the registration slip in the vehicle before entering to obtain it. Additionally, there is a question as to why the officer remained in the vehicle after turning ofif the engine. It appears he
*368
may have assumed that the search for the registration was just standard procedure in the stopping of a vеhicle—a procedure which should be reassessed in the light of the alternative procedures, such as license checks per radio and other advanced technological developments that may be available. The cases cited by the People supporting this proposition are all distinguishable. Thus,

We also note that when the officer is told of the location of the certificate, he need not allow the arrested person to personally obtain the certificate since the officer has the right to protect himself
(People

Walker
(1969)
Under the law, the People have the burden of justifying the warrantless search. While such a search might very wеll have been upheld as incident to arrest, the evidence presented at the suppression hearing in this case offers no justification for the seizure. Since the motion under Penal Code section 1538.5 was broad enough to apрly to the testimony as to observation of the gun, the motion to dismiss under Penal Code section 995 should be granted as to the felony.
Let a writ of mandate issue directing the superior court to suppress the seized gun and the testimony of the officer re observing the weapon and to enter an order dismissing the felony under Penal Code section 995. 5
Brown (G. A.), P. J., and Gargano, J., concurred.
Notes
The record is very unclear as to the precise physical position of the officer when the gun was first observed.

Vehicle Code section 2805 provides in part: “A member of the California Highway Patrol may inspect any vehicle of a type requirеd to be registered under .this code on a highway ... for the purpose of... investigating the title and registration of vehicles ....”
Nor need we discuss the situation in which the arrested person is so intoxicated that he is unconscious, or practicаlly so. Factually] this is not such a case, as is shown by the circumstances of appellant’s insistence about leaving the vehicle parked.
Of course, this opinion does not prohibit refiling and prosecution
