Most people are aware of the dangers of inclement weather like heavy rain, ice, and snow. But fog can be extremely dangerous, too. That’s because it can severely limit visibility to the point where seeing more than a few feet in front of your vehicle is difficult or impossible.

It’s important to never take fog lightly when you’re driving. Not only does it significantly increase your risks of being involved in a crash, but it can also worsen without warning. You may have visibility of dozens of feet, only to suddenly be unable to see more than one car length ahead.

Following these tips can help you reduce your risks while driving in light, medium, or heavy fog:

• Reduce your speed: Slowing down gives you more time to react and stop if necessary. Traveling below the speed limit allows you to adjust quickly to stopped or slowed traffic.

• Keep a safe distance: Maintain extra space between your car and the one in front to allow for sudden braking.

• Turn on headlights, but not your brights: Use low beams to see and be seen. High beams can reflect off fog and create glare, making visibility worse.

• Use fog lights wisely: If your vehicle has fog lights, use them with low beams. Turn them off when the fog clears to avoid blinding other drivers.

• Avoid high beams: They create a “white wall” effect that worsens visibility.

• Skip cruise control: You need full control of your speed at all times in fog.

• Avoid all distractions: Stay focused on the road, as hazards can appear suddenly.

• Listen for traffic: Open your windows slightly and turn off your radio to hear vehicles you cannot see.

• Follow road markings: Use the white fog line on the right side of the road as a guide, rather than the center line.

• Don’t pass other vehicles: Passing in fog is unpredictable and dangerous.

• Pull over safely if needed: If visibility is too low, turn on hazard lights, fully pull off the road, and leave only your hazard or parking lights on.

If you or someone you love gets injured in a fog-related crash, you may be eligible for compensation, especially if the other driver was speeding, distracted, or otherwise failed to drive safely. Contact the Nashville auto accident lawyers at Ponce Law today for a free consultation.
