Fog safety: Tips from the weather service for safe travels

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:

Reduce speed:

• Slow down and allow 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 available, employ your fog lights.

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:

• To ensure you are staying in the correct lane, use the road’s lane markings as a guide.

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 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 weather service recommendations, you can navigate foggy conditions more safely, reducing the risk of accidents and ensuring your well-being.
