These conditions can make driving challenging, so exercise extreme caution on the road, and if possible, consider delaying your trip. If driving through fog becomes inevitable, remember these safety guidelines: Moderate your speed: Slow down and allocate extra time for your trip to reach your destination safely. Visibility matters: Ensure your vehicle is visible to others by using low-beam headlights, which automatically activate your taillights. Utilize fog lights if your vehicle is equipped with them. Avoid high-beams: Refrain from using high-beam headlights, as they create glare that impairs your visibility on the road. Maintain safe gaps: Keep a considerable following distance to account for sudden stops or shifts in traffic patterns. Stay in your lane: Use the road’s lane markings as a guide to remaining in the correct lane. Visibility near zero: In cases of near-zero visibility due to dense fog, activate your hazard lights and seek a safe spot, like a nearby business parking lot, to pull over and stop. No 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 precautions from the NWS, you can navigate foggy conditions more safely, reducing the likelihood of accidents and ensuring your personal safety.
