A Drunk Driver Hit You. California law may allow more than standard damages.

Civil Liability for Drunk Driving Accidents in California

When a driver causes an accident while under the influence of alcohol or drugs, California law creates strong civil liability grounded in negligence per se and, in appropriate cases, the possibility of punitive damages under Civil Code § 3294.

California Vehicle Code § 23152 makes it unlawful to drive under the influence of alcohol, drugs, or a combination. A DUI charge or conviction is admissible in civil proceedings under Evidence Code § 1300 and supports a negligence per se argument under Evidence Code § 669: the statutory violation, if proven, establishes breach of the duty of care as a matter of law.

Unlike ordinary negligence cases, DUI accidents open the door to punitive damages under Civil Code § 3294. California courts have recognized that knowingly driving while intoxicated — with awareness of the danger this poses to others — can constitute "despicable conduct" or "conscious disregard for the rights and safety of others," both of which meet the § 3294 standard.

A criminal DUI case proceeds on the prosecution's timeline, which may not align with your civil interests. The criminal case must prove guilt beyond a reasonable doubt; the civil case requires only a preponderance of the evidence. Waiting for the criminal case to conclude before filing a civil lawsuit can exhaust the two-year statute of limitations. Civil and criminal proceedings can run simultaneously.

What to Do After a Drunk Driver Accident in California

Steps to take after a DUI accident in California that protect your health, preserve evidence, and preserve both the civil and criminal evidentiary record.

1
Call 911 immediately. Law enforcement will conduct field sobriety tests and, if warranted, a breath or blood test. The officer's DUI investigation creates the core evidentiary record for both criminal and civil proceedings. A chemical test result is among the most valuable evidence in a DUI injury case.
2
Request that field sobriety test observations be documented. Note and document any observations of impairment — slurred speech, odor of alcohol, erratic behavior, open containers in the vehicle. Your witness statement to police will be part of the official report.
3
Seek immediate medical attention. DUI crashes often involve high-speed impacts or head-on collisions, causing serious trauma. Emergency medical documentation links your injuries to the crash.
4
Document the scene thoroughly. Photograph both vehicles, road conditions, any skid marks or debris patterns, and any open containers visible in the other vehicle (before police arrive, if safely possible). Note any witnesses.
5
Obtain the police report and case number. Follow up to get the complete incident report, including the DUI investigation portion. Track the criminal case through your county's court public access system.
6
Preserve all evidence. Keep all medical records, bills, pay stubs, repair estimates, and any news coverage of the incident. Do not contact the at-fault driver or their insurer without understanding your rights.

Your Rights After a Drunk Driving Accident in California

Right to Compensatory Damages

You have the right to recover the full measure of economic and non-economic damages caused by the drunk driver's negligence — medical expenses (past and future), lost wages, diminished earning capacity, pain and suffering, emotional distress, and loss of enjoyment of life. There is no cap on compensatory damages in California automobile accident cases.

Right to Pursue Punitive Damages

Civil Code § 3294 entitles you to pursue punitive damages if you can prove by clear and convincing evidence that the defendant acted with malice, oppression, or fraud. California courts have recognized that conscious drunk driving — where the driver knew of the intoxication risk and proceeded anyway — can meet this standard. Punitive damages are awarded to punish and deter, separate from compensatory recovery.

Right to Criminal Case Evidence

Evidence obtained in the criminal DUI proceeding — BAC results, field sobriety test observations, police narrative, and ultimately any conviction — is usable in your civil case. Under Evidence Code § 1300, a criminal conviction for the same conduct is admissible in a subsequent civil action on the same facts.

Fault and Liability in DUI Accident Cases

A DUI charge or conviction triggers negligence per se under Evidence Code § 669. The statutory violation (CVC § 23152) establishes breach of the duty of care if the violation was a proximate cause of the injury. In practice, this means the intoxicated driver's negligence is treated as legally established, shifting the focus to causation and damages.

California's pure comparative fault rule still applies — if the injured plaintiff contributed to the accident, their recovery is reduced proportionally. However, fault reductions in DUI cases are typically modest, since the drunk driver's impairment is the dominant causal factor in most crashes.

Beyond the driver, California's dram shop rules (Business & Professions Code § 25602.1) may allow a claim against the bar or restaurant that served the driver, if the driver was an obviously intoxicated minor or a known habitual drunkard. Standard social host liability does not extend to adult drinkers under Civil Code § 1714(c).

Insurance in DUI Accident Cases

Standard automobile liability policies cover the insured driver's negligent acts, including drunk driving — the insurer cannot deny coverage to the injured third party solely because the driver was intoxicated. However, most policies exclude coverage for punitive damages, meaning any punitive award must be collected from the defendant personally.

If the drunk driver's liability limits are inadequate (California's minimums are $30,000 per person as of 2025), your own underinsured motorist (UIM) coverage may provide additional compensation for compensatory damages. UIM does not typically cover punitive damages.

If the driver was uninsured, uninsured motorist (UM) coverage under your own policy (Insurance Code § 11580.2) is the primary recovery path for compensatory damages. The approximately 16.5% uninsured driver rate in California makes UM coverage practically important.

Evidence That Matters in Drunk Driver Accident Cases

Uniquely valuable evidence in DUI accident cases includes: the law enforcement incident report including the DUI investigation narrative, chemical test results (BAC), field sobriety test observations, dashcam or surveillance footage capturing the other driver's driving pattern before the crash, witness accounts of the driver's behavior, and any receipts or records from establishments where alcohol was served.

In cases where a dram shop claim is possible, subpoenas or demand letters to the serving establishment for sales records, employee training logs, and surveillance footage should be issued promptly — video is often overwritten within 30 days. Bartender and server witness statements are important when the establishment disputes whether the driver appeared intoxicated at the time of service.
