Fog safety: Tips from the NWS for safe travels

If you need to drive through fog, remember these safety guidelines:

Moderate your speed:

• Slow down and allocate extra time for your trip to reach your destination safely.

Visibility priority:

• Ensure your vehicle is visible to others by using low-beam headlights, which also activate your taillights. If you have fog lights, use them.

Avoid high-beams:

• Refrain from using high-beam headlights, as they create glare that impairs your visibility on the road.

Keep your distance:

• Leave a safe distance between you and the vehicle in front of you to account for sudden stops or changes in the traffic pattern.

Stay in your lane:

• Use the road's lane markings as a guide to staying in the correct lane.

Visibility near zero:

• In extremely dense fog where visibility is near zero, the best course of action is to first turn on your hazard lights, then simply pull into a safe location such as a parking lot of a local business, and stop.

Limited parking options:

• If no designated parking area is available, pull your vehicle as far off the road as possible. Once stationary, deactivate all lights except the hazard flashers, engage the emergency brake, and release the brake pedal to ensure your tail lights are not illuminated, reducing the risk of other drivers colliding with your stationary vehicle.

By adhering to these recommendations from the NWS, you can navigate foggy conditions more safely, reducing the risk of accidents and ensuring your well-being.
