Law Enforcement Academy – Constitutional Law Practice Test

The key idea is that cars can be searched without a warrant if police have probable cause to believe the vehicle contains evidence or contraband. This is the automobile exception, rooted in the reality that vehicles are mobile and can be driven away quickly, so obtaining a warrant beforehand isn’t practical. When there is probable cause, officers may search the vehicle and the places within it where such evidence could reasonably be found, without first obtaining a warrant. That’s why the correct concept is that a vehicle may be searched without a warrant if there is probable cause to believe evidence is present. Consent is a separate basis for a warrantless search, not what the automobile exception requires. And it’s not true that a vehicle search always requires a warrant, nor that it can only be done with a warrant or consent.
