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 driving in fog becomes unavoidable, remember these safety tips:
Moderate your speed:
Slow down and allocate extra travel time to reach your destination safely.
Visibility matters:
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 a safe distance:
Maintain a generous following distance to account for abrupt stops or shifting traffic patterns.
Stay in your lane:
Use the road’s lane markings as a guide to remaining in the correct lane.
Zero visibility protocol:
In cases of near-zero visibility due to dense fog, initiate your hazard lights and locate a secure spot, such as a nearby business parking area, to pull over and come to a halt.
No 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 recommendations from the NWS, you can navigate foggy conditions with greater safety, mitigating the risk of accidents and prioritizing your well-being.
