Foggy mornings in California aren’t just inconvenient; they can be deadly. From sudden pileups on the I-5 to slow-motion rear-end collisions on winding roads, fog causes major accidents every year across the state.
Fog accounts for just 3% of weather-related crashes, but it’s responsible for over 25,000 crashes, nearly 9,000 injuries, and more than 460 deaths over 10 years, according to the FHWA. While less common than rain or snow, fog accidents often cause severe, multi-car collisions due to sudden stops and limited reaction time.
If you were involved in a car accident due to fog, you’re not alone, and you’re likely asking: What happens next? Who’s at fault? What should I do now?
Let’s walk through what California drivers need to know when it comes to fog-related accidents, legal responsibilities, and protecting yourself in a state where comparative fault can make or break your claim.
What to Do When the Road Is Foggy
Driving in foggy conditions demands a different level of caution. Here’s how to stay safe and what California law expects from you.
1. Slow Down—Even Below the Speed Limit
The California Basic Speed Law, Vehicle Code §22350, requires drivers to operate at a speed that is safe for current conditions, not just the posted speed limit. In fog, this usually means reducing your speed significantly.
2. Use Low-Beam Headlights or Fog Lights
High beams reflect off the fog and worsen visibility. Stick to low beams or dedicated fog lights, which cut through fog more effectively and help other drivers see you.
California law, CVC §24400, also requires headlights to be on when visibility drops below 1,000 feet, even during daylight.
3. Increase Your Following Distance
In clear weather, the recommended following distance is three seconds. In fog, double or triple that. You need more time to react to brake lights or sudden stops, especially when you can’t see more than a few car lengths ahead.

Even minor fender benders in fog can spiral into dangerous situations. Here’s what to do immediately following a crash in low visibility.
1. Move to Safety and Stay Visible
If your vehicle is drivable, carefully pull off the road and turn on your hazard lights. This reduces the risk of a chain-reaction crash, especially on high-speed roads or highways.
Fog causes major accidents by limiting reaction time, so staying visible is key to avoiding further collisions.
2. Call 911, No Matter How Small the Crash
In foggy conditions, police and emergency responders need to assess the risk of pileups or traffic buildup. Calling 911 documents the incident officially and ensures you and others are protected.
3. Take Photos and Notes Immediately
Photos and documentation are vital in fog-related crashes. Capture weather, skid marks, vehicle positions, and nearby traffic signs, where visibility is limited and memory may be unclear.
This evidence could help your car accident attorney prove fault and push back against insurance denials.

Fog doesn’t excuse poor driving. California drivers are still expected to use caution, and if they don’t, they may still be held legally responsible.
1. Drivers Must Adjust to Weather Conditions
Under California law, weather doesn’t remove liability. If a driver was speeding, tailgating, or failed to use headlights, they may be found negligent, even in dense fog.
2. California Is a Comparative Fault State
California follows a pure comparative negligence model. This means:
- Each driver can be assigned a percentage of fault.
- Your compensation is reduced by your share of fault.
3. What Is a 50/50 At-Fault Accident?
In fog accidents, insurers often assign 50/50 fault when both drivers contributed to the collision (e.g., neither had headlights on or both were speeding).
However, remember that this is not automatic or always fair. How fault is determined in California car accidents is more nuanced than you think. With strong evidence, a good lawyer can challenge the split and fight for a bigger share of your rightful compensation.
How to Build a Strong Legal Case After a Fog Crash
Even if visibility was poor, you still have the right to pursue compensation, especially if another driver acted carelessly.
1. Gather Witnesses and Statements
Independent accounts from passengers or bystanders can help paint a clear picture of what happened in unclear weather conditions.
2. Use Traffic and Weather Reports
A skilled attorney can pull official weather data, CHP records, and road condition logs to establish context and prove that the other party failed to drive with appropriate caution.
3. Don’t Automatically Admit Fault
Just because you rear-ended someone or got hit, doesn’t mean you’re legally to blame. These cases are nuanced and heavily depend on what should have been done based on the weather and road conditions.
Why You Need a Car Accident Attorney After a Fog Crash
Fog crashes are legally tricky. Don’t let the weather become an excuse for someone else’s recklessness or let insurers downplay your claim.
1. Insurance Companies Often Blame the Weather
They may argue that the crash was “unavoidable.” An experienced car accident lawyer knows how to combat this tactic with strong evidence, expert reports, and accident reconstruction.
2. You Could Be Owed More Than You Think
If the other driver failed to use headlights or follow road rules, they may be 100% liable even in fog. You deserve compensation for medical bills, car damage, lost income, and pain and suffering.
3. Protect Yourself From Fault Creep
Without legal guidance, you risk being assigned partial fault just for being in the accident. That’s how 50/50 at-fault accidents in California can unfairly reduce your payout.
Conclusion: Don’t Let Fog Obscure Your Rights
Fog clouds visibility, but it shouldn’t cloud your judgment after a crash. A moment of low visibility can lead to life-changing consequences: totaled vehicles, physical pain, emotional trauma, and months of dealing with stubborn insurance adjusters.
If you’ve been involved in a car accident due to fog in California, you’re not just facing the weather; you’re facing a complex legal situation where fault isn’t always obvious, and blame is often unfairly shared.
But here’s what matters most: You still have rights. You still have options. And you don’t have to navigate this alone.
