Texas Defensive Driving Written Practice Test

What is the best way to handle driving in foggy conditions?

1. Use high beams to improve visibility

2. Drive at the same speed as normal

3. Reduce speed and use low beams

4. Open windows to check outside

The correct answer is: Reduce speed and use low beams

Handling driving in foggy conditions requires adjustments to ensure safety, and reducing speed while using low beams is the most effective approach. Fog significantly decreases visibility, making it difficult to see other vehicles, traffic signs, and road conditions. By reducing speed, you provide yourself with more time to react to any hazards or obstacles that may suddenly appear. This cautious approach helps maintain control of the vehicle and reduces the likelihood of accidents. Using low beams is crucial because high beams can worsen visibility in fog, as the light reflects off the water droplets in the fog and creates glare, further obstructing vision. The other methods, such as driving at normal speed or using high beams, can lead to unsafe driving conditions. Similarly, opening windows may not help with visibility and does not address the core issue of reduced sight due to fog. Thus, adapting your speed and choosing the appropriate lighting are essential for safe navigation in such weather conditions.
