Car Accident While Working in California: Your Two Claims

You were on the clock, driving to a client, making a delivery, or running an errand for your boss, when another driver hit you. Now you are hearing about a workers' comp claim from HR and getting calls from the other driver's insurance company. This post explains how those two tracks fit together in California, what each one pays, and the payback rules that catch people off guard at settlement.

The short version: you can usually pursue both. But the workers' comp insurer has a right to be repaid out of what you recover from the other driver, and how you settle affects your future comp benefits.

You usually have two claims, not one

A crash on the job in California often creates two separate claims against two separate payers.

• Workers' comp, against your employer's insurance. Labor Code § 3600 makes an employer liable for comp "without regard to negligence" for injuries "arising out of and in the course of the employment." It does not matter who caused the crash. Whether your particular trip counts as part of your job depends on what you were doing, so do not assume either way.
• A personal injury claim, against the at-fault driver. Labor Code § 3852 says your claim for comp "does not affect" your right to recover "all damages proximately resulting from the injury" against anyone other than your employer. The other driver is not your employer, so filing for comp does not protect them.

What you generally cannot do is sue your own employer. Under Labor Code § 3602, when the conditions for comp are met, comp is generally the exclusive remedy against the employer. The other driver is a different story.

What workers' comp pays, and what it leaves out

Comp is no-fault, and it is also limited. According to the Division of Workers' Compensation (DWC):

• Claim form. Your employer must give or mail you a claim form (the DWC 1) within one working day after learning about your injury.
• Medical care. Within one day of filing, your employer must authorize appropriate treatment, and you can receive up to $10,000 in care while the claim is being investigated. If the claim is not denied within 90 days, it is presumed covered.
• Lost wages. Temporary disability pays two-thirds of the gross wages you lose while recovering, up to a weekly maximum. You do not pay income tax on those benefits.

What comp does not pay is spelled out on the DWC's own page: benefits "do not include damages for pain and suffering or punitive damages." And two-thirds of your wages is not all of your wages.

What the claim against the other driver adds

This is why the second claim matters. A personal injury claim against the at-fault driver can seek the losses comp leaves out:

• The rest of your lost income, not just two-thirds of it.
• Pain, suffering, and the ways the injury has limited your daily life. We covered how that part is valued in how pain and suffering is calculated in California.

The driver claim runs on ordinary fault rules, so expect the other side's adjuster to question how the crash happened and how badly you are hurt. The recorded statement traps apply here exactly as they do in any other crash.

Your employer's insurer gets paid back

Here is the part that surprises people. When your employer's insurer has paid comp benefits and you recover money from the other driver, the insurer does not simply walk away.

• It has a lien. Under § 3856, after the court sets reasonable litigation expenses and attorney's fees, the employer is allowed a "first lien" for what it spent on compensation. Settlements work similarly under § 3860.
• It can take a credit going forward. Under § 3861, the net amount you recover, after fees, expenses, and reimbursing the employer, can be credited against the comp benefits your employer would otherwise owe you in the future. In practice, a settlement with the driver can pause future comp payments, including medical treatment, until that credit is used up.
• Notice is required. You can settle with the other driver without your employer's consent under § 3859, but the settlement remains subject to the employer's right to recover what it paid. Under § 3860, a settlement is not valid or binding without notice to both the employer and the employee.

None of that makes the driver claim a bad idea. It means the two claims have to be worked out together, with the lien amount and the future credit known before anyone signs a release.

New in 2026 for police officers and firefighters

SB 487 took effect January 1, 2026, and changed these rules for peace officers and firefighters employed by a city, a county, a city and county, or a fire protection district. When the injured employee's total damages exceed what is left after the employer's claim, and the at-fault party's insurance limits are not enough to cover everyone, the employer can receive no more than one-third of the at-fault party's liability policy limits. In those cases the employer also cannot take a credit against the employee's future comp benefits.

If the other driver has no insurance

Your own uninsured motorist coverage may still apply, with a few work-specific twists written into Insurance Code § 11580.2:

• UM coverage does not apply where it would benefit a workers' comp carrier, so the comp insurer generally cannot reach your UM benefits.
• Your insurer may reduce what it pays under UM by the comp benefits paid and payable to you.
• If you have a comp claim, UM arbitration generally waits until your condition is "stationary and ratable." If you claim permanent disability, the comp claim usually has to be resolved first.

The two-year UM deadline still runs. We explained it in hit by an uninsured driver in California.

What this means in California

Several deadlines run at once.

• Report the injury to your employer right away. Labor Code § 5400 calls for written notice to the employer within 30 days, and the DWC warns that missing it "could lose your right" to benefits.
• Two years against the other driver. The personal injury statute of limitations under CCP § 335.1 is generally two years from the injury.
• Six months if a public vehicle hit you. If the at-fault vehicle belonged to a city, county, or other public entity, a government claim is generally due within six months.
• Shared fault reduces, it does not erase. Comp does not depend on fault. The driver claim does, and under California's pure comparative negligence rule any share of fault assigned to you reduces your recovery rather than eliminating it.

Practical next steps

Get medical care and tell your employer in writing that you were hurt in a work crash. Fill out and return the DWC 1 claim form, keeping a copy and proof of the date you delivered it. Get the police report and the other driver's insurance information. Keep your pay stubs and every comp benefit notice, because both claims will need them. Before you sign anything with the other driver's insurer, find out what your employer's insurer is claiming as a lien and how a settlement will affect your future comp benefits. If you want someone to look at how the two claims fit together in your case, a free consultation costs nothing and there is no fee unless there is a recovery.
