Delaware Driver Education State Practice Test

What is the best practice when driving in foggy conditions?

1. Use high beams to see better

2. Reduce speed and increase following distance

3. Drive at the speed limit regardless

4. Turn on hazard lights

The correct answer is: Reduce speed and increase following distance

Driving in foggy conditions requires extra caution due to reduced visibility. Reducing speed is critical because it allows a driver to have more time to react to obstacles, other vehicles, and potential hazards that may become visible suddenly. Increased following distance is equally important, as it ensures that there is ample space between your vehicle and the one in front, allowing for safe stopping without the risk of rear-ending another vehicle if it suddenly slows down or stops. Using high beams in fog is not advisable since the light can reflect off the fog, creating a glare that limits visibility even further. Maintaining the speed limit in such conditions can be dangerous if visibility is compromised, as it does not account for the surrounding environment. Finally, turning on hazard lights can confuse other drivers, as they may interpret it as an indication of a stationary vehicle or an emergency, rather than as a precaution for reduced visibility. Therefore, the best practice in foggy conditions is to reduce speed and increase following distance, ensuring safer driving in challenging visibility.
