Common Defenses Against Car Accident Claims in California (and How to Respond)

Insurance companies and defense attorneys generally rely on a handful of recurring arguments to reduce or deny car accident claims in California. These defenses aim to shift blame, question your injuries, or challenge the timing of your claim rather than to find the truth. Recognizing them early can help you avoid common missteps, and a free case review with a legal professional can help you understand which ones may apply to your situation.

Under California’s pure comparative negligence rule, you can generally still recover damages even if you were partially at fault, though your award is reduced by your percentage of fault. This principle is reflected in California Civil Code §1431.2 and related case law, meaning a driver found 30% responsible may still recover roughly 70% of their damages in most cases. Insurers often try to inflate your share of blame to shrink their payout, so understanding how fault is allocated matters. A legal professional can review the evidence and help you push back on an unfair fault percentage.

Failure to mitigate is a defense arguing that you did not take reasonable steps to limit your damages, such as delaying medical treatment or ignoring a doctor’s advice. In most cases, California law expects injured people to act reasonably to reduce the harm they suffer, and insurers may point to gaps in treatment to argue your injuries are not as serious as claimed. Keeping consistent medical records and following prescribed care generally helps counter this argument. If an insurer raises it, a free case review can help you understand your options.

Insurers often argue that your injuries stem from a pre-existing condition rather than the accident, but California’s “eggshell plaintiff” principle generally protects you here. Under this rule, a defendant typically takes the victim as they find them, meaning you may still recover if the crash aggravated or worsened a prior condition. Clear medical documentation comparing your condition before and after the collision is usually key to defeating this defense. A legal professional can help gather records that distinguish new harm from old.

A lack-of-causation defense claims that the accident was not the actual cause of your injuries or losses. To recover in California, you generally must show that the other party’s negligence was a substantial factor in causing your harm. Insurers may point to other possible causes, low-speed impact, or delayed symptoms to dispute this link. Medical opinions, accident reconstruction, and prompt treatment records often help establish causation, and a legal professional can help build that connection.

In California, you generally have two years from the date of the accident to file a personal injury claim, as set by Code of Civil Procedure §335.1. Missing this deadline can bar your claim entirely, which is why insurers may raise it as a complete defense. Certain situations, such as claims against a government entity, can carry much shorter deadlines, sometimes as little as six months. Because exceptions and shortened windows may apply, it generally helps to speak with a legal professional as soon as possible.

You can generally counter common defenses by preserving strong evidence and acting promptly after a crash. Photographs, witness statements, a police report, and consistent medical treatment all help rebut arguments about fault, causation, and the seriousness of your injuries. Here are some steps that often help: seek care right away, follow your treatment plan, keep records of your losses, and avoid giving recorded statements before consulting a legal professional. A free case review can help you understand which strategies fit your case.

If your California car accident claim succeeds, you may be able to recover both economic and non-economic damages. These can generally include medical expenses, future care costs, lost wages, reduced earning capacity, pain and suffering, and property damage. The value of a claim depends heavily on the specific facts, the severity of injuries, and how strongly the evidence rebuts the defenses above.
