How do reasonable suspicion and probable cause differ in traffic stops?

• A. Reasonable suspicion means an arrest.
• B. Reasonable suspicion justifies a stop; probable cause qualifies the officer to arrest or search.
• C. Reasonable suspicion requires a warrant.
• D. Probable cause only applies to administrative detentions.

Answer: (B)

Reasonable suspicion is the level of belief needed to briefly detain a driver for investigation. It must be based on specific, articulable facts and rational inferences from those facts—not a mere hunch. In a traffic stop, that level of justification lets an officer pull someone over, check license and registration, and ask questions or run checks while the stop lasts, all without violating rights. Probable cause is a higher standard that requires facts and circumstances that would lead a reasonable person to believe that a crime has been committed or that evidence of a crime will be found in the place to be searched. This standard is what authorizes an officer to arrest or to conduct a search (often without a warrant) once more compelling evidence is gathered during the stop. So, a stop can be made with reasonable suspicion, but arrest or a search requires probable cause.
