A disabled vehicle highway injury case usually starts with something ordinary: a car breaks down, a tire blows out, or a mechanical failure forces a driver to pull over. What happens next, whether that stopped vehicle is properly warned of, moved, or protected before another car strikes it, often determines who bears legal responsibility for the injuries that follow. Many people assume a breakdown collision is nobody's fault but bad luck. California law often says otherwise, because more than one party can share responsibility when a disabled vehicle is struck on a highway shoulder.

Many people assume that if their car breaks down and they get hit while stopped on the shoulder, they have no one to blame but bad luck or their own vehicle's mechanical failure. That assumption is often wrong. California law recognizes that multiple parties can share responsibility when a disabled vehicle is struck: the driver who failed to see and avoid a stopped car with adequate warning time, a highway patrol or roadside assistance response that was unreasonably delayed, and, in some cases, a state or local entity responsible for maintaining a safe highway shoulder and adequate lighting or signage. Vehicle Code section 22651 and related provisions govern the removal of disabled vehicles from roadways, and understanding how these rules were followed, or ignored, is often central to determining fault when a stopped vehicle is struck.
Timing evidence is often the single most important fact in a disabled vehicle highway injury case. If a vehicle had been stopped, visible, and using hazard lights or flares for an extended period before it was struck, that supports an argument that the striking driver failed to exercise reasonable care in observing and avoiding a foreseeable hazard. If, instead, a roadside assistance or highway patrol response was requested but significantly delayed, that delay itself can become a point of legal inquiry, particularly where a public agency's response time falls outside its own internal standards. Cell phone records, 911 call logs, roadside assistance dispatch records, and any nearby traffic camera or dashcam footage should be secured immediately, because this evidence establishes the timeline that the entire liability analysis depends on.
California's comparative fault system lets a jury assign a percentage of responsibility to every party whose conduct contributed to the collision, rather than forcing an all-or-nothing result.
Even where a disabled vehicle was clearly marked and reasonably visible, the striking driver's conduct in the moments before impact stays central. Was the driver distracted by a phone, fatigued, speeding, or impaired? Cell phone records, event data recorder information, and witness accounts of speed and lane position help establish whether the driver had a genuine opportunity to see and avoid the vehicle and simply failed to do so.
When a roadside assistance or highway patrol response is requested but significantly delayed, that delay can become its own point of legal inquiry, particularly where a public agency's response time falls outside its own internal standards and leaves a vehicle exposed to danger longer than it reasonably should have been.
Sometimes the underlying hazard is not the stopped car but an unsafe shoulder, inadequate lighting, or a shoulder too narrow to offer a genuinely safe stopping area. Government Code section 835 allows a claim against a public entity for a dangerous condition of public property when the entity had notice of the danger and failed to address it.
Warning devices matter too. Whether the disabled driver used hazard lights, triangles, or flares, and how visible they were given the time of day, weather, and traffic, can support that driver's claim against a striking driver and can also be raised to argue comparative fault.
California's comparative fault system allows a jury to allocate percentages of responsibility across every party whose conduct contributed to a collision, rather than forcing an all-or-nothing outcome. In a disabled vehicle case, the striking driver may bear a majority share for failing to see and avoid a marked hazard, while a public entity bears a smaller share for an unsafe shoulder design, and, in rare cases, the disabled driver bears some share for inadequate warning devices when a safer option was reasonably available. If a state or local agency's delayed response, inadequate signage, or unsafe shoulder design contributed to the danger, that agency may share responsibility under Government Code section 835. Claims against public entities carry a strict six-month government claim deadline, far shorter than the two-year statute of limitations that applies to claims against private drivers, and missing it usually bars the claim permanently.
When a family member is killed while stopped on a highway shoulder or narrow median, surviving spouses, children, and in some circumstances other dependents may bring a wrongful death claim for the support the person would have provided, funeral and burial expenses, and the loss of that person's love, companionship, and guidance. The same multi-party analysis applies, so a thorough investigation launched immediately after the collision is just as critical as it is for a surviving injury victim. Prior results do not guarantee a similar outcome, and every case depends on its own facts. The Homampour Law Firm works on a contingency fee basis, advancing the costs of the case, so there is no upfront cost to have a claim evaluated.

Refer a caseYes, a driver who fails to see and avoid a stopped vehicle with a reasonable opportunity to do so can be held liable, and in some cases a public entity or emergency responder's delay may also contribute to liability.
Yes, under California Government Code section 835, a public entity can be liable for a dangerous condition of a highway shoulder, such as inadequate width or lighting, if it had notice of the danger and failed to address it within a reasonable time.
You generally must file a government claim within six months of the incident before suing a public entity, compared to the two-year statute of limitations that applies to claims against private drivers.
