Suing the At-Fault Driver While on Workers' Compensation

Attorney Answer

Yes — collecting workers' compensation does not stop you from suing the driver who caused the crash, and as a passenger you are almost certainly not at fault no matter which driver was.

Cal. Lab. Code § 3600 makes workers' compensation the exclusive remedy against your employer. It does not reach anyone else. Cal. Lab. Code § 3852 says so directly: an employee's compensation claim does not affect the right to bring a civil action for damages against any person other than the employer whose negligence caused the injury, and the employer or its carrier may bring its own action or join yours.

That both drivers blame each other is not a problem you must solve before filing. You can pursue both and let them fight over percentages. California is a pure comparative fault state — fault reduces a recovery in proportion to it rather than barring it — and as a seated passenger there is usually no fault to assign to you.

The two systems pay for different things. Comp pays medical care and part of your lost wages. It does not pay for pain, suffering, or a year of your life. Only the civil claim does.

The trade-off is the lien. Under Cal. Lab. Code § 3856(b), when you bring the third-party action the employer or carrier holds a first lien on your judgment for benefits paid — but the court first allows a reasonable attorney's fee out of the recovery before that lien is satisfied. That sequencing decides what you keep.

What you can do

1. Ask your comp adjuster in writing for a printout of all benefits paid to date. That figure is the lien. 2. Open a claim with both drivers' liability insurers, naming both — do not wait for them to agree on fault. 3. Get the traffic collision report and the names of every witness; the fault dispute will be decided on physical evidence, not on what the drivers say. 4. Keep proof of the full period you were off work, including wages comp did not replace. 5. Have a lawyer review the lien before you settle anything. Comp liens are often negotiable, and the fee-first rule in § 3856(b) is frequently applied wrong.

⏱ Time limits apply. The civil claim against the driver runs on California's general two-year personal-injury deadline, which is separate from and much shorter than your open workers' compensation case. An active comp claim does not extend it. The exact date depends on your specific facts.
