What is a valid reason for a police stop of a vehicle?

• A. A personal dislike for the driver.
• B. A random citizen's complaint without details.
• C. Reasonable suspicion of a traffic violation or criminal activity, supported by objective facts.
• D. A hunch based only on appearance.

Answer: (C)

A valid vehicle stop rests on reasonable suspicion that a traffic violation or criminal activity is underway, and that suspicion must be grounded in objective facts the officer can observe or verify. It isn’t about personal feelings, guesses, or vague rumors. If a driver commits a known traffic violation, such as speeding or running a stop sign, that observable conduct provides the necessary basis for a stop. Similarly, if the officer has specific details or behavior suggesting criminal activity—like suspicious actions or matching a reported description with corroborating facts—that also justifies stopping the vehicle.

Disliking a driver, a random complaint without details, or a hunch based solely on appearance do not meet this standard because they lack observable, verifiable facts.
