When driving at night using low beams, what should you do?

1. Flash your high beams

2. Speed up

3. Slow down

4. Turn on your hazard lights

The correct answer is: Slow down

When driving at night using low beams, slowing down is the most appropriate action. Low beams provide limited visibility compared to high beams, illuminating only a short distance ahead. By reducing your speed, you give yourself more time to react to obstacles, other vehicles, or potential hazards that may be in your path. This is especially important at night when visibility is compromised. Speeding up can be dangerous since it decreases your reaction time, making it harder to respond to unforeseen circumstances. Flashing your high beams is generally not recommended as it can blind oncoming drivers and create a hazardous situation. Turning on your hazard lights is unnecessary unless you are experiencing an emergency or a breakdown, as they can confuse other drivers about your intentions. Thus, slowing down is a prudent choice for ensuring safety while driving at night with low beams.
