When may a police officer conduct a warrantless search of a vehicle?

• A. Warrantless vehicle searches are never allowed.
• B. When there is probable cause to believe the vehicle contains evidence or contraband, or during certain authorized circumstances.
• C. Only with the occupant's explicit verbal consent.
• D. Only when a search incident to arrest is performed on the vehicle's occupant.

Answer: (B)

Warrantless vehicle searches are allowed when there is probable cause to believe the vehicle contains evidence or contraband, or under other authorized circumstances such as consent, exigent circumstances, or inventory procedures. The rule, often called the automobile exception, rests on the car’s mobility and the relatively lower expectation of privacy in vehicles, so once probable cause exists, officers can search the vehicle and seize items connected to that probable cause. This explanation also accounts for other legitimate ways a warrantless search can occur—through voluntary consent or under urgent situations where obtaining a warrant isn’t feasible, or during inventory procedures after a lawful detention. The other choices are too absolute or narrow: a blanket ban on warrantless vehicle searches isn’t correct, consent isn’t the only pathway, and a search incident to arrest of the occupant isn’t the only basis for a vehicle search.
