On Sunday at 4:07 a.m. the National Weather Service released a dense fog advisory in effect until 10 a.m. for San Gabriel Valley.

Guidance from the NWS for navigating foggy conditions

When a dense fog advisory is issued for your area, it means that widespread dense fog has developed and visibility can plummet to a quarter-mile or less. These conditions pose challenges for travel, so exercise extra 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 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 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 a safe 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.

Zero visibility protocol:

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 recommendations from the NWS, you can navigate foggy conditions with greater safety, mitigating the risk of accidents and prioritizing your well-being.
