What is a Carroll arrest?

A Carroll arrest refers to a legal principle stemming from the U.S. Supreme Court case Carroll v. United States (1925). It allows law enforcement officers to conduct a warrantless search and seizure of a vehicle if they have probable cause to believe it contains evidence of a crime. This principle is based on the inherent mobility of vehicles, which could be driven away before a warrant can be obtained. The Carroll doctrine emphasizes the balance between the need for effective law enforcement and the protection of individual rights against unreasonable searches.
