Police across the United States reported an estimated 6.18 million motor vehicle crashes in 2024, according to the National Highway Traffic Safety Administration. Those crashes injured about 2.42 million people and killed 39,254. Many involve one obvious at-fault driver and one insurance policy. A meaningful share involves something more complicated.
After a serious crash, the injured person is usually dealing with physical recovery, unpaid medical bills, and lost income at the same time. Who pays depends on the facts of the collision, how each driver behaved, and the law of the state where it happened. This article explains how liability works, with a focus on California, where a single crash can involve the driver, an employer, a vehicle owner, a government agency, and several insurance policies at once.
Fault Starts With the Driver and Rarely Stops There
The core claim is negligence. Under California Civil Code § 1714, everyone owes others a duty of ordinary care. A driver who runs a red light, reads a phone, speeds, follows too closely, or drives impaired breaches that duty, and the breach must have caused the harm being claimed.
The list of possible defendants beyond the driver is longer than most people assume:
| Party | When they may be liable in California |
| Employer | The driver was acting within the scope of employment, such as making deliveries or driving between job sites |
| Vehicle owner (Veh. Code §§ 17150–17151) | Any owner who permitted to drive is liable, but generally only up to $15,000 per person and $30,000 per accident for injuries, unless the owner was independently negligent (for example, lending a car to someone known to be unfit) |
| Repair shop | Returned a vehicle with defective brakes or tires |
| Manufacturer | A defective part or design caused or worsened the crash or the injuries |
| Property owner | An overgrown hedge or structure on private land blocked the view at an intersection |
| Government agency | A dangerous condition of public property, such as a poorly designed curve or a broken signal |
Each theory has its own proof, its own defenses, and often its own insurer. Identifying them early matters because evidence about a vehicle, a road, or an employer’s policies can disappear quickly.
Comparative Fault Splits the Bill
Almost nobody is entirely blameless in a collision, and states handle shared fault in three broad ways:
- Pure comparative fault: recovery is reduced by the injured person’s percentage of fault, however large. California follows this rule.
- Modified comparative fault: recovery is reduced the same way, but barred once the injured person’s share reaches 50 or 51 percent, depending on the state.
- Contributory negligence: any fault at all bars recovery. Only a handful of jurisdictions still follow it.
That is why a percentage that sounds trivial is worth fighting over. Ten points of comparative fault on a seven-figure claim is a six-figure argument, and it is usually decided by crash reconstruction, cell phone records, and vehicle data rather than by competing descriptions of what happened.
The Defendants People Do Not Think Of
Alcohol Servers
Alcohol remains a leading factor in fatal crashes. NHTSA’s 2024 data estimate that 11,904 people, about 30 percent of all 2024 traffic deaths, died in crashes involving a driver with a blood alcohol concentration of 0.08 or higher. Many states allow claims against a bar or social host who served the driver. California is much more restrictive: it generally shields bars and social hosts from liability for serving adults, with a narrow exception under Business and Professions Code § 25602.1 for serving alcohol to an obviously intoxicated minor.
Government Agencies
Public entities can be responsible when the road itself contributed, through poorly timed signals, a missing guardrail, a curve built below design standards, or vegetation that blocks sight lines. Under Government Code § 835, a public entity is liable for a dangerous condition of its property if it created the condition or had notice in time to fix it. These claims carry a much shorter deadline: a written claim generally must be presented within six months under § 911.2, compared with the usual two years for an injury lawsuit under Code of Civil Procedure § 335.1.
A Highway Maintenance Case
Road-condition claims can be among the most significant in this area. Among the results listed on the author’s firm’s case results page, a jury returned a $31.5 million verdict against the State of California for failing to maintain Highway 138 in a safe condition, after a crash left the firm’s client with catastrophic brain and spinal cord injuries. Cases like this one depend on maintenance records, prior complaints, and engineering testimony gathered well before trial, and on meeting the six-month claim deadline at the start.
Past results depend on the specific facts of each case and do not guarantee a similar outcome in any other matter.
Commercial and Rideshare Vehicles
Commercial and rideshare vehicles add coverage layers that depend on status rather than conduct. In California, rideshare insurance requirements change with the driver’s app status: when the app is on but no ride is accepted, primary coverage is $50,000 per person and $100,000 per incident plus $200,000 in excess coverage; from acceptance until the passenger exits, liability coverage is $1 million. Since January 1, 2026, SB 371 has reduced the required uninsured and underinsured motorist coverage for rideshare passengers from $1 million to $60,000 per person and $300,000 per occurrence. None of this is visible from the roadway, which is why the driver’s app records matter.
Insurance Is the Real Answer to Who Pays
Liability establishes responsibility. Policy limits establish collectibility, and the second often decides what an injured person actually receives. California raised its minimum liability limits on January 1, 2025 to $30,000 per person and $60,000 per accident, but a driver carrying only the minimum can be fully at fault for a catastrophic injury and represent a small fraction of the eventual recovery.
That often routes the analysis back toward the injured person’s own policy. Uninsured and underinsured motorist coverage under Insurance Code § 11580.2 can become the largest available source in a serious case, and medical payments coverage can cover bills while liability is sorted out. Rules on combining policies differ enough that a figure quoted from a friend’s case is of little use. Find Attorneys’ overview of compensation after a California car accident describes the categories of damages that may be recovered.
Rather than asking what a case is worth, the more useful question is: which insurance policies cover this crash, and what must be proven to recover under each? Someone consulting an Orange County car accident lawyer or any attorney about a serious crash should expect that question to come first.
Evidence That Disappears in Weeks
The answer to that question is often shaped by evidence collected in the first several weeks. Damaged vehicles are repaired or sold for scrap, and with them goes the event data recorder, the device that stores speed, braking, and seatbelt use in the seconds before impact. In California, Vehicle Code § 9951 generally allows that data to be downloaded only with the owner’s consent or a court order, so a written request to preserve the vehicle should go out early. Surveillance video from nearby businesses is often overwritten within days, and phone records and witness memories fade on a similar timeline.
