What should you do if your headlights fail while driving?

If your headlights fail while driving, it's crucial to take immediate and safe actions to ensure your visibility and the safety of yourself and others on the road. Using your parking lights and turn signals can help alert other drivers to your presence, reducing the risk of an accident. This is especially important in low visibility conditions or at night when headlights are the primary source of light.

Leaving the roadway as soon as it's safe to do so is also vital. It allows you to transition out of the flow of traffic, minimizing any potential hazards for both yourself and other drivers. By doing this, you create a safer environment in which you can assess the situation, seek help, or wait for conditions to improve before continuing your journey.

In contrast, continuing to drive (like in the first option) can be extremely dangerous, as you would lack sufficient visibility to navigate safely. Flashing headlights (the third option) may confuse other drivers since they typically signal different intentions, and pulling over immediately could put you at risk of being struck, especially if you're in the middle of traffic without a safe spot to stop. Thus, utilizing parking lights and turn signals while finding a safe place to exit the roadway is the most responsible and safest course of action.
