Heavy tule fog continues to create dangerous driving conditions across California’s inland valleys. On Friday afternoon, both directions of Vasco Road between Livermore and Brentwood were closed after multiple crashes occurred in dense fog, according to the California Highway Patrol. The closure lasted from about 2:45 p.m. to just after 4 p.m. as crews worked to clear the roadway. During the response, a Contra Costa County Fire Protection District captain was struck by a vehicle while assisting at one of the crash sites and suffered a lower extremity injury. Officials urged drivers to avoid the area and slow down due to severely limited visibility.
These crashes come as East Bay valleys have experienced persistent tule fog for more than two weeks, with officials warning that additional dense fog advisories may be issued. Last year, the dangers of these conditions were tragically demonstrated on January 6, 2024, when a massive pileup on Interstate 5 in Kern County involved nearly 40 vehicles, including 18 tractor-trailers, and resulted in two fatalities and nine injuries. Visibility in that crash dropped to as little as 10 feet, leaving drivers with little time to react.
What Is Tule Fog and Why Is It So Dangerous?
Tule fog is a thick, low-lying fog that forms in California’s Central Valley after heavy rainfall, typically between late fall and early spring. Because of the region’s flat terrain and surrounding mountains, the fog becomes trapped, lingering for hours or even days at a time.
What makes tule fog especially hazardous is how quickly visibility can change, often dropping to less than one-eighth of a mile with little warning. These sudden conditions significantly increase the risk of serious collisions.
Fog is one of the leading causes of weather-related crashes nationwide, contributing to hundreds of fatalities and thousands of injuries each year. Large commercial trucks face even greater risks due to their size, weight, and longer stopping distances, which can turn a single mistake into a catastrophic pileup.
How Can Drivers Stay Safe in Foggy Conditions?
While fog can be unpredictable, taking the following precautions can help reduce the risk of an accident:
- Slow down. Driving at reduced speeds allows more time to react to hazards you may not see until the last moment.
- Use low-beam headlights. High beams reflect off fog and worsen visibility. Low beams and fog lights are safer.
- Increase following distance. Leave extra space between vehicles to allow for safe stopping.
- Use lane markings as a guide. Road lines can help you stay oriented when visibility is poor.
- Avoid sudden braking. Gradual slowing helps prevent chain-reaction crashes.
- Keep windows clear. Use windshield wipers and defrosters to maintain visibility.
If fog becomes too dense to drive safely, pull off the road to a safe location such as a rest area or parking lot. Turn on your hazard lights and wait for conditions to improve. When possible, delaying travel until fog lifts, often by late morning or early afternoon, can help prevent serious accidents.
