After a crash in a California highway work zone, the driver who hit the work zone is usually the first party responsible. A contractor that set up the cones, signs and lane closures may share fault if the traffic control was unsafe, and Caltrans or another public agency may be responsible for a dangerous condition it created or knew about. A highway worker who is hurt on the job generally receives workers’ compensation from the employer, but can still sue a negligent driver or another outside party. Claims against Caltrans require a written government claim within six months.
What was reported?
In a November 2, 2026 news release, Caltrans issued a statewide call to action for Crash Responder Safety Week, urging drivers to slow down and move over for stopped vehicles with flashing lights, cones or flares. Work zones and roadside crash scenes remain some of the most dangerous places on the highway for workers and drivers alike. We use the campaign as a springboard to explain the law, not to describe any specific crash.
Who can be responsible for a work zone crash?
- The driver. Speeding, distraction or impairment in a work zone is negligence. California also requires drivers to move over or slow down for stopped emergency, tow and Caltrans vehicles with flashing lights, under Vehicle Code section 21809, and fines are higher in designated work zones under section 42009.
- The contractor. Private contractors on state projects must follow traffic control plans and the California Manual on Uniform Traffic Control Devices. Missing warning signs, a confusing taper or unlit equipment at night can support a claim.
- Caltrans or another public entity. Government Code section 835 allows a claim for a dangerous condition of public property, and section 815.2 for an employee’s negligence. Defenses such as design immunity can apply.
- A trucking company. If a commercial truck caused the crash, the carrier may be liable for its driver. See our truck accident page.
What if I am a motorist hurt in a work zone?
You may have a claim against the driver who hit you, and in some cases against a contractor or the agency if the lane closure itself was unsafe. Comparative fault applies, so an insurer may argue you should have slowed down. Photos of the signs, cones and lane shift taken soon after the crash are often the best evidence, because work zones change daily.
What if a highway worker is hurt or killed?
Workers’ compensation is generally the only remedy against the employer, under Labor Code section 3602. But a worker, or a worker’s family, can still sue an outside party such as the negligent driver or a different contractor, under Labor Code section 3852. Family members of a worker who died may bring a wrongful death claim against those third parties. Our wrongful death page explains who can file.
How does a claim against Caltrans work?
Before suing a public entity, you generally must present a written claim within six months of the injury under Government Code section 911.2. If the claim is rejected, a lawsuit usually must follow within six months of the written rejection under section 945.6. Our government claims page and our guide to a missed six-month claim deadline walk through the steps.
What to save
- Photos and video of the work zone, signs, cones, arrow boards and lighting.
- The CHP report number and the names of any crew members present.
- The project or contractor name shown on signs or equipment.
- Witness names and dashcam video.
- Medical and employment records.
What are the deadlines?
- Two years for most injury and wrongful death lawsuits against private parties, under Code of Civil Procedure section 335.1.
- Six months for a written claim when a public entity is involved, under Government Code section 911.2. Our government claims page explains the process.
- Policy notice periods for your own insurer. Report the crash early, even if you think another driver will pay.
