Sailing in fog: safety tips from the weather service

When a Dense Fog Advisory is issued for your area, it means that widespread, dense fog has developed and visibility may drop to a quarter mile or less. These conditions pose travel challenges, so use extreme caution on the road or consider postponing your trip if possible.

If you must drive in foggy conditions, keep the following safety tips in mind:

Moderate your speed:

Slow down and allow extra time for your trip to reach your destination safely.

Visibility matters:

Make sure your vehicle is visible to others by using low beam headlights, which automatically activate your taillights. Use fog lights if your vehicle is equipped with them.

Avoid high beams:

Avoid using high beams, as they create glare, making it harder to see what’s ahead of you on the road.

Keep your distance:

Maintain a generous following distance to account for sudden stops or changes in traffic.

Stay in your lane:

Use the road’s lane markings as a guide to stay on track.

Visibility near zero:

In extremely dense fog where visibility is close to zero, the best course of action is to first turn on your hazard lights, then simply pull over to a safe location, such as a local business parking lot, and pull over .

Limited parking options:

If no parking area is available, park your vehicle as far from the side of the road as possible. Once stopped, turn off all lights except the hazard warning lights, engage the emergency brake and release the brake pedal to ensure your tail lights are not illuminated, reducing the risk of d other drivers collide with your stationary vehicle.

By adhering to these recommendations from the weather service, you will be able to navigate foggy conditions more safely, mitigating the risk of accidents and prioritizing your well-being.
