Vehicle searches and consent in California

Start with what a California driver actually must submit to. Vehicle Code § 2806 lets a salaried police officer or deputy sheriff, or a reserve officer listed in Penal Code § 830.6, who has reasonable cause to believe a vehicle is not equipped as the code requires or is in an unsafe condition endangering any person, require the driver to stop and submit the vehicle to an inspection and appropriate tests. Vehicle Code § 2805 lets the California Highway Patrol, and city police, sheriff’s office, or district attorney investigators whose primary responsibility is vehicle theft, inspect a registered vehicle or an identifiable vehicle component on a highway or at a garage, repair shop, dismantler’s lot, shredding facility, salvage pool, or similar establishment, to establish rightful ownership, with § 2805(c) directing that inspections be timed to minimize interference with business operations. Vehicle Code § 2814.2(a) requires a driver to stop at a posted sobriety checkpoint. None of those is authority to open your glove box, your bag, or your trunk looking for evidence.

The largest California-specific change to roadside search practice came from Proposition 64 in November 2016. Health and Safety Code § 11362.1(a) makes it lawful for a person 21 or older to possess or transport up to 28.5 grams of cannabis, up to eight grams of concentrated cannabis including cannabis contained in products, and to possess up to six living plants. Subdivision (c) then removes that lawful conduct from the officer’s toolkit entirely: the cannabis is not contraband, is not subject to seizure, and the conduct cannot be the basis for a detention, a search, or an arrest. In practical terms, a California officer cannot build a warrantless car search on the presence of a legal quantity of cannabis in the passenger compartment.

The limits on that are precise, and they are where an officer can still get traction. Health and Safety Code § 11362.3(a)(4) says § 11362.1 does not permit possession of an open container or open package of cannabis while driving, operating, or riding in the passenger seat or compartment of a motor vehicle, and § 11362.3(a)(7) and (a)(8) bar smoking or ingesting while driving or while riding as a passenger. Vehicle Code § 23222(b)(1) makes possession on your person, while driving on a highway, of an opened or seal-broken cannabis receptacle or loose cannabis flower not in a container an infraction punishable by a fine of not more than $100. Subdivision (b)(2) exempts the same items when they are in the trunk, and subdivision (c) exempts a qualified patient or identification card holder who is carrying a current card or physician’s recommendation and whose cannabis is in a sealed, resealed, or closed container. Vehicle Code § 23222(a) applies the parallel rule to an opened alcoholic beverage container carried on the driver’s person.

Your phone is treated separately and much more strictly than the vehicle around it. Under the California Electronic Communications Privacy Act, Penal Code § 1546.1(c), a government entity may access electronic device information by physical interaction with the device only on a warrant issued under Penal Code § 1523 and subject to § 1546.1(d), on a wiretap order, on a tracking device warrant, with the specific consent of the authorized possessor, with the owner’s specific consent where the device was reported lost or stolen, on a good faith belief in an emergency involving danger of death or serious physical injury, or under the narrower conditions listed for lost, abandoned, or correctional facility devices and for people on parole, postrelease community supervision, or an express search condition of probation or pretrial release. A warrant under § 1546.1(d)(1) must describe the information with particularity, and § 1546.1(d)(2) requires that unrelated information seized be sealed and not further reviewed, used, or disclosed absent a court order. Under § 1546.1(e)(1) a court may appoint a special master to keep the search to the warrant’s objective.

Two procedural rules shape the moment consent is requested. Vehicle Code § 2806.5(a), added by AB 2773 (Stats. 2022, Ch. 805) and operative January 1, 2024, requires a peace officer making a traffic or pedestrian stop to state the reason for the stop before engaging in questioning related to a criminal investigation or a traffic violation, and to document that reason on any citation or police report resulting from the stop. Subdivision (b) excuses that only where the officer reasonably believes withholding the reason is necessary to protect life or property from an imminent threat, including terrorism or kidnaping. A request to search made before the reason is stated is a request made in breach of the section.

Finally, the honest part. Whether a particular consent was voluntary, and whether an officer had probable cause without it, is decided by California courts under federal Fourth Amendment standards rather than under an independent state rule. That is a consequence of the California Constitution itself: article I, § 28(f)(2), the Right to Truth-in-Evidence adopted by the voters, provides that except as provided by a statute enacted by a two-thirds vote of each house of the Legislature, relevant evidence shall not be excluded in any criminal proceeding. California has enacted no statute requiring an officer to advise a driver of the right to refuse a search, and no statute requiring consent to be written or recorded. Refusal is not a crime and is not itself evidence of anything, but it is your act to make clearly and out loud.

There is no California penalty for declining a search. The consequences run along other lines. 5 rises or falls on federal Fourth Amendment grounds. 1(c) takes that justification away and also makes the cannabis non-seizable. 4. What can be cited at the roadside is the conduct the exceptions describe: an open or seal-broken cannabis receptacle or loose flower on the driver’s person under Vehicle Code § 23222(b)(1), an infraction with a fine of not more than $100 unless the item is in the trunk under § 23222(b)(2), and an opened alcoholic beverage container on the driver’s person under § 23222(a). 1(b) lets the Attorney General, a district attorney, or a city attorney seek a $25,000 civil penalty against each violator.
