Alberta Class 7 License Practice Test

What should you do if your low-beam headlights fail at night?

1. Continue driving without lights

2. Use only your hazard lights

3. Switch to high-beam headlights

4. Immediately pull over

The correct answer is: Switch to high-beam headlights

In the event of low-beam headlight failure at night, switching to high-beam headlights is the appropriate action to take. High-beam headlights provide greater visibility, illuminating the road ahead more effectively than low beams. This can help you see further and detect obstacles or other vehicles more easily in the dark, significantly improving safety conditions. It is important to remember that using high beams should be done cautiously. When there is oncoming traffic or closely following another vehicle, you should switch back to low beams to avoid blinding other drivers. The capacity of high beams to enhance visibility in dark environments makes them a practical alternative when low beams are not operational. Choosing to continue driving without lights or relying solely on hazard lights poses significant safety risks, as it severely diminishes your visibility and that of your vehicle to others. Pulling over immediately is not required unless absolutely necessary, but continuing with high beams while considering the conditions keeps you safer on the road.
