Driving substantially slower than normal traffic without a safety-related reason may:
Correct answer: A. – Impede the normal movement of traffic
In Tennessee, a driver may not travel so slowly that the vehicle impedes the normal and reasonable movement of traffic. This rule does not apply when reduced speed is necessary for safe operation or compliance with the law. Drivers must adjust speed for traffic, visibility, weather, and roadway conditions rather than automatically matching faster traffic.
