You Were in a Car Accident in California. Here Is What the Law Gives You.

Car Accidents Under California Law

California sees over 500,000 reported traffic collisions annually. The legal framework governing every one of them — pure comparative fault, a two-year statute of limitations, and updated minimum insurance requirements — applies whether the accident was a low-speed fender-bender or a high-speed freeway collision.

A California car accident claim requires proof of four elements: the other driver owed you a duty of care (every driver owes this to every other road user), they breached that duty through negligent conduct, their breach caused your injuries, and you suffered damages as a result. California Vehicle Code violations — running a red light, failing to yield, following too closely — establish negligence per se under Evidence Code § 669, meaning the violation itself proves duty and breach without further argument.

California updated its mandatory minimum liability insurance requirements on January 1, 2025 under Senate Bill 1107. Drivers must now carry at least $30,000 per person / $60,000 per accident in bodily injury coverage and $15,000 for property damage. These minimums frequently prove inadequate in serious injury cases, making underinsured motorist (UIM) coverage — required to be offered under Insurance Code § 11580.2 — an important supplement.

When a government vehicle caused the accident — an LAPD cruiser, a county public works truck, a Caltrans vehicle — the Government Claims Act (Government Code § 910 et seq.) requires filing an administrative claim with the responsible entity within six months of the accident. This six-month deadline runs simultaneously with the two-year civil limitations period and is a jurisdictional prerequisite to any lawsuit against a government entity.

What to Do After a Car Accident in California

The steps taken in the hours and days after a California car accident directly affect the strength of any subsequent insurance claim or lawsuit. Follow these in order.

1. Call 911 if anyone is injured. Law enforcement prepares a Traffic Collision Report that documents Vehicle Code violations, witness information, and the officer’s fault observations. Obtain the report number at the scene.
2. Photograph everything before vehicles move. All vehicle damage, license plates, road conditions, skid marks, traffic controls, and visible injuries. The scene exists for minutes; photographs last through trial.
3. Exchange complete driver information. Full name, license number, plate, insurance carrier, policy number, and phone number for every driver involved.
4. Collect independent witness information. Names and phone numbers of anyone who witnessed the collision or its immediate aftermath.
5. File the DMV SR-1 within 10 days. California Vehicle Code § 16000 requires this report when injury, death, or damage exceeding $1,000 occurred. Failure results in license suspension.
6. Seek medical evaluation immediately. Whiplash, concussion, and soft-tissue injuries present delayed symptoms. A same-day medical record links your injuries to the accident.
7. Notify your insurer; decline recorded statements to the other driver’s insurer. You must cooperate with your own insurer. You are not required to give a recorded statement to the adverse insurer.

Your Rights After a California Car Accident

The right to recover regardless of your own fault

California’s pure comparative fault system from Li v. Yellow Cab Co., 13 Cal.3d 804 (1975) permits recovery regardless of the plaintiff’s fault percentage. A driver found 40% responsible for a collision still recovers 60% of total damages from the other party. This is among the most plaintiff-favorable fault systems in the country — 33 states bar recovery at 50% or 51% plaintiff fault. Insurers routinely argue elevated plaintiff fault to reduce payouts; the pure comparative system limits the effect of those arguments to reduction, not elimination.

The right to UM/UIM coverage for uninsured drivers

California Insurance Code § 11580.2 requires insurers to offer uninsured and underinsured motorist coverage with every policy. If the at-fault driver had no insurance or insufficient coverage, your own UM/UIM policy pays the difference. Approximately 16–17% of California drivers are uninsured. For hit-and-run accidents involving an unidentified driver, UM coverage applies when there was physical contact and law enforcement was notified within 24 hours.

The right to full compensatory damages

California Civil Code § 3333 provides that tort damages shall compensate for all detriment proximately caused by the defendant’s negligence. This includes past and future medical expenses, lost wages, lost earning capacity, property damage, and non-economic damages — pain and suffering, emotional distress, and loss of enjoyment of life. California does not cap these damages in vehicle accident cases. MICRA’s damage caps apply only to medical malpractice claims, not vehicle accidents.

How Fault Is Determined in California Car Accident Cases

California applies pure comparative fault to vehicle accident cases. A jury assigns a fault percentage to each party whose negligence contributed to the collision. Total damages are then reduced by each party’s assigned percentage. A plaintiff found 30% at fault with $200,000 in damages recovers $140,000. There is no threshold that bars recovery — even a plaintiff found 90% at fault retains the right to recover 10% of damages.

Vehicle Code violations establish negligence per se under Evidence Code § 669. When a driver ran a red light (CVC § 21453), made an unsafe lane change (CVC § 22107), or followed too closely (CVC § 21703), that statutory violation creates a presumption of negligence — duty and breach are proven without additional argument. The plaintiff still must establish causation and damages.

In multi-vehicle accidents, Proposition 51 (Civil Code § 1431.2) modifies the comparative fault framework for non-economic damages. Each defendant is severally liable for non-economic damages only in proportion to their own fault percentage. Economic damages — medical bills, lost wages — remain subject to joint and several liability, meaning any one defendant may be required to pay all economic damages regardless of their individual fault percentage.

Rear-end collision presumption. California courts apply a rebuttable presumption that the rear driver was negligent in rear-end collision cases, based on the duty to maintain a safe following distance under CVC § 21703. The rear driver must produce evidence of a non-negligent explanation — sudden stop by the front vehicle, brake failure — to rebut the presumption.

Insurance Considerations in California Car Accident Cases

California’s updated minimum liability requirements under Senate Bill 1107 (effective January 1, 2025) require $30,000/$60,000/$15,000 coverage. Despite the increase from the prior $15,000/$30,000/$5,000 minimums in place since 1967, these amounts remain far below the actual cost of serious injury. Most significant injury claims quickly exceed the at-fault driver’s minimum-limits policy, triggering the injured party’s own underinsured motorist (UIM) coverage.

California is an at-fault (tort) state. The at-fault driver’s liability insurer is the primary recovery source — not the injured party’s own carrier. This means fault determination is the central disputed issue in every California vehicle accident insurance claim.

Common insurer tactics in California car accident claims include: attributing elevated fault percentages to the plaintiff; disputing causation between the accident and specific injuries (particularly where the plaintiff had pre-existing conditions); disputing future medical necessity; and offering early low settlements before the full extent of injuries is known. These tactics are predictable and consistent across California’s high-volume insurance litigation market.

Medical payments (MedPay) coverage, while optional, pays the policyholder’s medical bills regardless of fault and without requiring a fault determination. MedPay ranges from $1,000 to $10,000 in most California policies and provides immediate cash flow for medical treatment while the liability claim proceeds.

Evidence That Matters in Car Accident Cases

• Traffic Collision Report (TCR). The responding officer’s documentation of Vehicle Code violations, driver statements, witness names, and preliminary fault findings. Obtainable from the responding agency (LAPD, CHP, local PD) using the report number from the scene.
• Photographs and video from the scene. Vehicle positions, damage patterns, skid marks, road conditions, traffic signals, and visibility obstructions. Scene photographs are the most powerful evidence in fault disputes — they show physical facts that testimony cannot fabricate.
• Event Data Recorder (EDR/black box) data. Most vehicles manufactured since 2013 record pre-crash speed, braking, throttle position, and steering angle. This data overwrites quickly — a preservation demand must be sent immediately after serious collisions.
• Witness statements. Independent witnesses who observed the collision or its immediate aftermath. Witness accounts frequently differ from driver accounts and carry significant weight with juries.
• Medical records and billing. Emergency room, primary care, specialist, and therapy records linking injuries to the specific accident mechanism. Bills and explanation of benefits documents support economic damages.
• Dashcam footage. From the involved vehicles, from bystanders, and from fixed traffic cameras. Security camera footage from nearby businesses frequently captures intersections and must be demanded before it overwrites.
• Cell phone records. In distracted driving cases, cell phone records obtained through discovery can establish whether the at-fault driver was texting or on a call at the time of the collision.
• DMV and insurance records. The at-fault driver’s prior license suspensions, prior accidents, and prior claims are admissible in certain circumstances and relevant to punitive damages arguments.
