What should you do if your headlights fail while driving at night?

Answer: B — Activate your emergency flashers and pull over to a safe stop

When your headlights fail while driving at night, it is crucial to activate your emergency flashers and pull over to a safe stop. This action makes your vehicle more visible to other drivers, alerting them that you are experiencing issues. Stopping safely ensures that you are not in danger of an accident due to reduced visibility. Continuing to drive without headlights, regardless of the distance to home, is risky because it significantly impairs your ability to see the road and for others to see you. Using high beams may not be effective, as it could dazzle other drivers and further increase the risk of an accident. Turning on interior lights can help you see inside your vehicle, but it does not make you visible to others on the road, nor does it illuminate the road ahead for safe navigation. Therefore, safely pulling over is the most responsible and prudent action to take in this situation.
