Which option best describes the purpose of a lawful traffic stop?

• A. To seize cars and issue penalties.
• B. To investigate unrelated crimes.
• C. To enforce traffic laws and promote safety; requires reasonable suspicion of a violation or risk.
• D. To collect information for future use.

Answer: (C)

A lawful traffic stop exists to enforce traffic laws and promote roadway safety. An officer stops a driver when there is a reasonable suspicion of a traffic violation or a safety risk that needs addressing. This keeps the stop tied to a present, observable issue rather than being arbitrary, and it allows the officer to address the violation or risk immediately, which may result in penalties if warranted. The other ideas—seizing cars and issuing penalties as the main goal, investigating unrelated crimes, or collecting information for future use—do not fit because they either miss the focus on immediate safety and law enforcement of a current violation, require justification beyond a current observed issue, or treat the stop as a data-gathering exercise rather than addressing a present risk or violation.
