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 venture out in foggy conditions, keep these safety tips from the NWS in mind:
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.
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.
No parking options:
If there is no parking lot or driveway to pull into, pull your vehicle off to the side of the road as far as possible. Once you come to a stop, turn off all lights except your hazard flashing lights, set the emergency brake, and take your foot off of the brake pedal to be sure the tail lights are not illuminated so that other drivers don’t mistakenly run into you.
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.
