What Happens If You're Hit by an Uninsured Driver in California?

It's a situation nobody plans for.

You're stopped at a light, or cruising down the 10, and another driver hits you. Cars are damaged. Maybe someone is hurt. Then the other driver says the words that change everything:

"I don't have insurance."

Now what?

In California, this happens more often than most people realize. If you carry the right coverage on your own policy, you may still be protected. If you don't, you could be left paying for someone else's mistake.

First, Understand How Common This Is

California requires drivers to carry auto liability insurance. But a significant percentage of drivers on California roads are uninsured — and many more carry only minimum limits that can disappear quickly in a serious accident.

So the practical question isn't just "Is the other driver insured?"

It's:

"Am I protected if they're not?"

Uninsured Motorist Coverage Protects You

Uninsured motorist coverage (UM) is designed to step in when the at-fault driver has no liability coverage at all.

If an uninsured driver injures you or your passengers, your UM coverage may pay for:

• Medical expenses
• Lost wages
• Pain and suffering related to the injury

In California, insurers must offer you this coverage when you buy an auto policy. You can decline it in writing — but that's rarely a good idea.

What About Drivers Who Have Some Insurance — Just Not Enough?

There's a second, related coverage that matters just as much: underinsured motorist coverage (UIM).

UIM applies when the at-fault driver has insurance, but their liability limits are too low to fully cover your injuries or damages.

Example: suppose the other driver carries California's minimum limits and you have serious injuries from the accident. Once their policy limits are exhausted, your UIM coverage may help cover the remaining damages, up to your own policy's limits.

In California, UM and UIM are typically offered together. Ask your agent to show you exactly what your policy includes.

Who Pays for Your Car?

Injury-related damages are handled by UM/UIM. But what about your vehicle?

That depends on your physical damage coverage:

• Collision coverage may pay to repair or replace your vehicle after an accident — regardless of who's at fault or whether the other driver is insured.
• If you don't carry collision coverage, recovering vehicle damage from an uninsured driver often means pursuing them directly, which can be slow, difficult, and sometimes unsuccessful.

A hit-and-run driver who is never identified is generally treated like an uninsured driver for UM purposes — but rules on how that applies can be specific, so review your policy or ask your agent.

Doesn't California Require Insurance? Why Is This My Problem?

Legally, yes — California requires drivers to carry minimum liability limits. But a law on paper doesn't pay your medical bills after an uninsured driver runs a red light.

The reality is that you can't control whether other drivers follow the law. You can only control how well your own policy protects you.

That's why I tell people: your auto policy isn't just coverage for damage you might cause. It's also your safety net for damage others cause you.

How Much Uninsured Motorist Coverage Should You Carry?

A common approach is to match your UM/UIM limits to your liability limits. If you carry $250,000/$500,000 bodily injury liability, ask about carrying the same limits for UM/UIM.

Why? Because the coverage that protects your family matters just as much as the coverage that protects strangers.

In my experience, the cost of raising UM/UIM limits is often modest compared to the protection it adds.

Practical Steps After the Accident

If you're hit by a driver who turns out to be uninsured:

1. Call the police and get a report. Documentation matters for the claim.
2. Get the other driver's information — name, contact info, plate number, vehicle description.
3. Take photos of the scene, damage, and road conditions.
4. Get medical attention if anyone is hurt, even if the injury seems minor.
5. Notify your insurance company promptly. UM/UIM claims have their own process and timelines.

The Bottom Line

You can't make other drivers buy insurance. You can make sure an uninsured driver's mistake doesn't become your financial emergency.

Check your policy today. If you don't carry uninsured and underinsured motorist coverage — or your limits are low — that's a conversation worth having with your agent.
