What is the legal definition of a traffic stop?

• A. Temporary detention to conduct some enforcement action or to conduct an investigation
• B. Arrest without probable cause
• C. Random vehicle check without justification
• D. A routine vehicle inspection

Answer: (A)

A traffic stop is a temporary detention by a police officer to enforce traffic laws or to investigate a potential violation. This means the stop is not an arrest—it's a brief seizure based on a legitimate basis, such as a witnessed traffic violation or reasonable suspicion of involvement in a crime. The detention should be limited to addressing that purpose, with the officer typically asking for license, registration, and proof of insurance and may run checks, while the driver is not free to leave only as long as the investigation or enforcement task remains ongoing. The stop ends once the matter is resolved and the person may be free to go, unless new facts give rise to probable cause to arrest or other lawful grounds to seize the person further. This definition distinguishes a stop from an arrest, from random vehicle checks without justification, and from a routine vehicle inspection.
