Navigating fog: Safety tips by the NWS
If a dense fog advisory is issued for your area, it means that widespread dense fog has developed and visibility often drops to just a quarter-mile or less. These conditions can make driving challenging, so exercise extreme caution on the road, and if possible, consider delaying your trip.
If you must drive in foggy conditions, keep the following safety tips in mind:
Moderate your speed:
Slow down and allow extra travel time to reach your destination safely.
Visibility priority:
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:
Maintain a significant following distance to account for abrupt 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 situations of near-zero visibility due to dense fog, activate your hazard lights and seek a secure location, such as a nearby business’s parking lot, to pull over and come to a stop.
Limited parking options:
If no parking area is available, pull your vehicle as far to the roadside as possible. Once stationary, turn off 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.
