Texas Defensive Driving Written Practice Test

What should drivers do when driving in fog?

1. Use high beam headlights and speed up

2. Use low beam headlights and drive at a reduced speed

3. Turn on hazard lights and drive rapidly

4. Keep headlights off and rely on street lights

The correct answer is: Use low beam headlights and drive at a reduced speed

When driving in fog, using low beam headlights and driving at a reduced speed is crucial for safety. Low beam headlights are designed to illuminate the road immediately in front of the vehicle without causing glare that can reflect off the fog, which is common with high beams, potentially reducing visibility for both the driver and other road users. Driving at a reduced speed allows drivers to have better control over their vehicle and gives them more time to react to sudden changes in the road or any obstacles that may not be clearly visible. This approach minimizes the risk of accidents, as reduced visibility in fog can make it harder to judge distances and speeds. The other options present strategies that could worsen visibility or lead to dangerous driving conditions, such as speeding or using high beams, which can create glare, making it difficult for drivers to see the road clearly. Turning on hazard lights while driving rapidly also poses a danger, as this can confuse other drivers about your intentions and might not sufficiently alert others in low-visibility situations.
