Several vehicles far ahead suddenly show brake lights. What should you do?

Correct answer: C – Reduce speed and prepare to stop
Brake lights on several vehicles ahead signal that traffic may be slowing or stopping. Ease off the accelerator, increase your readiness to brake, and preserve enough following distance for a controlled stop. Looking beyond the nearest vehicle helps you respond earlier and avoid abrupt maneuvers.
