What basis supports the automobile exception to the warrant requirement?

• A. The mobility of vehicles makes the search easier in all cases.
• B. Consent from owner is always sufficient.
• C. The vehicle being in a public place negates the exception.
• D. The mobility of vehicles and probable cause to believe evidence is present in the vehicle.

Answer: (D)

The basis for the automobile exception is that vehicles are inherently mobile, so when police have probable cause to believe evidence or contraband is inside, they may conduct a warrantless search. The car can be moved quickly, and potential evidence could be moved, hidden, or destroyed if police had to wait for a warrant. That urgency is what justifies skipping the warrant requirement for the vehicle and its immediate compartments once there is probable cause. Importantly, the search is grounded in probable cause—not mere suspicion—and it applies regardless of where the vehicle is located. The scope can reach the interior of the vehicle and the compartments within that could reasonably contain the evidence.

The other ideas don’t fit as well: mobility doesn’t guarantee an easier search in every situation, consent is a separate authorization route and isn’t what the automobile rule rests on, and being in a public place does not remove the applicability of the exception.
