What key distinction did Carroll v. United States draw between searches of a dwelling and a motor vehicle?

• A. Warrant can be easily obtained for vehicles
• B. Vehicles can be moved quickly, making warrants impractical
• C. Vehicle searches require consent
• D. Vehicles do not require probable cause

Answer: (B)

The main idea is the automobile exception: due to a vehicle’s mobility, police can search a car without a warrant if they have probable cause to believe it contains evidence. Carroll v. United States recognized that cars can be moved out of the jurisdiction or beyond the reach of officers, making it impractical to obtain a warrant in time. Because the car can quickly be driven away, waiting for a warrant is not reasonable, so a probable-cause search of the vehicle is permissible without one. In contrast, a dwelling sits fixed in place and carries a much higher expectation of privacy, so a warrant is typically required to search it unless there are urgent, exceptional circumstances. So the correct answer highlights that vehicles can be moved quickly, making warrants impractical.
