According to the DPS Commercial Driver’s License (CDL) manual, the best advice for driving in fog is to avoid driving in it altogether. Fog significantly reduces visibility, making driving extremely dangerous. If driving in fog is unavoidable, it is crucial to take extra precautions to ensure safety. Here are the recommended steps:
- Slow down: Reduced visibility means you have less time to react to obstacles. Driving slower allows for more time to make safe decisions and respond to hazards.
- Use low-beam headlights: High-beam headlights can reflect off the fog, further reducing visibility. Low beams cut through the fog and make your vehicle more visible to others.
- Turn on fog lights (if your vehicle has them): Fog lights are designed to help with visibility in foggy conditions by lighting the road directly in front of you, without reflecting off the fog like high beams would.
- Increase following distance: Maintain a larger-than-usual gap between your vehicle and the one in front of you. This helps give more reaction time in case the vehicle ahead stops suddenly.
- Use road markings as a guide: In heavy fog, focusing on the painted lane markings helps keep you in your lane and oriented on the road.
- Avoid stopping on the road: If you must stop, do so well off the road and turn on hazard lights to alert other drivers. Stopping on the road in fog can be extremely dangerous as other drivers may not see your vehicle in time to avoid a collision(truckingtruth)(defensivedriving).
These safety measures are designed to minimize risks associated with driving in fog, ensuring better visibility and safer driving conditions for all road users.
