On Tuesday at 6:51 a.m. the National Weather Service issued a dense fog advisory in effect until 10 a.m. The advisory is for Central Sacramento Valley, Southern Sacramento Valley and Northern San Joaquin Valley.

The NWS says to expect, “Visibility one quarter mile or less in dense fog.”

“Low visibility could make driving conditions hazardous,” says the NWS. “If driving, slow down, use your headlights, and leave plenty of distance ahead of you.”

Guidance from the NWS for navigating foggy conditions

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 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 headlights, as they create glare that impairs your visibility on the road.

Keep your distance:

Maintain a significant following distance to account for abrupt 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 strategy:

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

Limited parking options:

If there is no parking lot or driveway to pull into, pull your vehicle off to the side of the road as far as possible. Once you come to a stop, turn off all lights except your hazard flashing lights, set the emergency brake, and take your foot off of the brake pedal to be sure the tail lights are not illuminated so that other drivers don’t mistakenly run into you.

By adhering to these precautions from the NWS, you can navigate foggy conditions more safely, reducing the likelihood of accidents and ensuring your personal safety.
