There were about 36,640 deaths resulting from car accidents in 2025, according to the estimates of the National Highway Traffic Safety Administration. This number is a decrease of 6.7% compared to 2024. NHTSA also reported a 6.3% year-over-year decline in fatalities for the first quarter of 2025 alone.
Fault itself does not identify who is responsible for the accident. There are actually several variations to the rules in different states that determine whether one can recover any amount at all. Or how insurance companies will respond to the case. The variance between a contributory negligence state and a comparative negligence state may result in the difference of tens of thousands of dollars.
In fact, the California car accident statistics have one of the highest counts of motor-vehicle crashes in the United States. This is mostly because it has a huge population and a very wide roadway system, stretching everywhere.
So whether you are chasing compensation for medical expenses, lost income, property harm, or pain and suffering, it matters a lot to know how your state’s fault rules work, because it can be beneficial in maximizing what you recover.
Contributory Negligence: Any Fault Bars Recovery
There are four states that apply the principle of contributory negligence at present. These are Alabama, Maryland, North Carolina, and Virginia.
In contributory negligence, if it can be shown that the individual involved in an accident had any part in causing the accident, no matter how slight his/her part is, then the individual is not entitled to compensation at all.
It is an absolute principle: if there was even partial negligence on the part of the claimant, there is no compensation whatsoever.
As a rule, it is accepted that such a strict requirement is very stringent in legislation, even in jurisdictions that do not practice it, but the jurisdictions in question do not want to give up their position anyway.
Until 2025, Maryland and D.C. modified their rules regarding contributory negligence, adding carve-outs for vulnerable road users, i.e., pedestrians, bicyclists, and other such people who were not in the motor vehicle.
And Arizona also follows a pure comparative negligence rule. This means a person may still recover damages even if they share some responsibility for the accident, according to personal injury lawyer Erik L. Mullins and the firm’s overview. However, compensation may be reduced based on the percentage of fault assigned to them.
The traditional doctrine applies to drivers. It is essential for the insurance adjusters to find something that can be regarded as contributory negligence of the victim in such cases.
Pure and Modified Comparative Negligence
Other states, like California, New York, and Florida, on the other hand, apply comparative negligence purely. This implies that fault is apportioned between all involved parties, and each gets compensation after being deducted their share of fault.
For instance, a driver who was at 80% fault and incurred damages worth $100,000 would still be able to get $20,000 from the other party, which may be confusing but intended.
California alone logs nearly close to half a million police-reported crashes a year, and it gives at least a little sense of how frequently these “fault allocation” issues actually get argued, or worked out, in practice within a single pure comparative negligence state.
Most states, on the other hand, use some form of modified comparative negligence, letting the injured party recover proportionally until the point where his fault percentage goes past a set cutoff, usually 51%, while fewer places use a 50% limit.
So a driver with 40% fault in a 51% threshold jurisdiction would be able to collect $60,000 for damages that add up to $100,000; the very same driver in a contributory negligence jurisdiction would recover absolutely nothing.
No-Fault States: A Different System Altogether
In 12 states where there is no-fault car insurance, Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania, and Utah, drivers who are injured must make an initial claim with their personal injury protection (PIP) insurance company, regardless of whether the accident was their fault. In Kentucky, New Jersey, and Pennsylvania, drivers can instead choose to opt out of the no-fault system in favor of traditional tort liability coverage.
Also, in Kentucky, New Jersey, and Pennsylvania, there is an option for drivers to enter into the no-fault insurance scheme.
The main application of the no-fault car insurance scheme applies only to personal injury cases, while damage to the vehicle can still be claimed from the other party. No-fault laws also prohibit people from filing a case against the other party for pain and suffering unless certain conditions are met.
Those conditions differ depending on each state’s law. In Florida, for instance, one must have suffered permanent and serious injuries, whereas in Michigan, one must have suffered a serious impairment of a body function, and in New York, serious injuries or medical expenses of more than $50,000.
How Insurance Companies Determine Fault
Insurers do not automatically accept the findings in police reports. Instead, they carry out an independent investigation, where they look at the accident report, interview each driver and any witnesses, look at the pictures of the damage to each car, and in some cases, review surveillance camera videos and vehicle data recorder logs.
Each insurer reaches its own conclusions regarding fault, and they may come to different conclusions, which explains why disputes can be referred to intercompany arbitration under state insurance rules.
In comparative negligence jurisdictions, there is a strong motive on the part of insurers to blame as much fault as possible on a claimant, since each percentage that is allocated to the injured party means less liability for the insurer.
That explains why percentages of fault in disputed cases are often negotiated before a settlement and why evidence collected at the scene before cars are moved and memory fades is important.
Scenarios That Shift Fault Allocation
There is a rebuttable presumption of a failure by the trailing driver to keep a safe distance from the leading car in most states. It can be rebutted by showing the lead driver suddenly swerved into the lane of the trailing driver, the headlights were faulty, or the lead driver suddenly and unnecessarily braked.
There is a default presumption for left-turn crashes of a duty to yield on behalf of the turning driver, who will be mostly at fault unless it can be shown that the lead car was speeding to a point where the accident was inevitable.
Multi-vehicle collisions result in a complicated apportionment since there would need to be separate considerations on the individual actions of each car.
Just because the driver in the middle rear-ends another car following an accident in the back does not necessarily exonerate him from any responsibility with regards to the front collision, depending on whether the back collision is a proximate cause for the front one.
What Happens When Fault Is Assigned to You
When you are found partially liable, this reduces your settlement and might even raise your insurance rates. However, liability is not the same thing as negligence since the percentages of fault are assigned by insurers through their claims rules.
The state’s rules regarding liability make up a big part of how well you’ll do. If you were driving in a contributory negligence jurisdiction and were only 5% at fault in an accident where the damages amounted to $200,000, you could collect nothing. If you had been in a pure comparative negligence jurisdiction, you would have collected $190,000.
If you were in a no-fault state, your total claim would be limited to what your PIP insurance covers.
