Which statement about driving substantially slower than normal traffic is correct?
Correct answer: B – It is prohibited when it impedes normal traffic unless necessary for safety or required by law
New York prohibits driving so slowly that you impede the normal and reasonable movement of traffic. The rule does not apply when the reduced speed is necessary for safe operation or compliance with law. A driver must consider both the lawful maximum speed and the effect an unnecessarily low speed has on traffic.
