Fog safety: Tips from the weather service for safe travels

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

Reduce 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 also activate your taillights. If you have fog lights, use them.

Avoid high-beams:

• Refrain from using high-beam lights, as they create glare, making it more difficult for you to see what’s ahead of you on the road.

Keep your distance:

• Keep a considerable following distance to account for sudden stops or shifts in traffic patterns.

Stay in your lane:

• Use the road’s lane markings as a guide to staying 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 weather service precautions, you can navigate foggy conditions more safely, reducing the likelihood of accidents and ensuring your personal safety.
