California charges impaired driving as DUI. The term DWI appears nowhere in the California Vehicle Code, so the short answer to the question in the title is that no legal difference exists here. Texas, New York, and a number of other states split the two labels, and drivers who move to California tend to bring the word with them. Under Vehicle Code § 23152, the state uses one charge for alcohol, drugs, prescription medication, or any combination of them.
That answer stops mattering the moment a drunk driver hits you. What matters then is Vehicle Code § 23153, the charge filed when an impaired driver causes bodily injury to someone else, and what that charge does for the civil claim you file separately from the criminal case.
The criminal case will not pay your medical bills
The district attorney prosecutes the driver. You are a witness in that case, not a party to it. Whatever restitution a judge orders covers a fraction of what a serious injury costs, and it arrives in installments over years.
Your civil claim runs on its own track, in its own court, under a lower standard of proof. Prosecutors must prove impairment beyond a reasonable doubt. You must show it by a preponderance of the evidence, meaning more likely than not. A driver acquitted of DUI can still be held liable for every dollar of your damages, and that outcome happens regularly.
DUI vs. DWI: What's the Difference? 2
The conviction hands you the negligence argument
Evidence Code § 669 establishes negligence per se: when a driver violates a statute designed to protect people like you from the harm you suffered, the violation creates a presumption of negligence. A DUI conviction, or even the BAC reading itself, moves the fight away from whether the driver behaved carelessly and onto the value of your injuries.
California sets the limit at 0.08% for most drivers, 0.04% for commercial license holders, and 0.01% for anyone under 21. A driver impaired by prescription medication or narcotics faces the same charge with a BAC of zero.
Drunk driving opens the door to punitive damages
In Taylor v. Superior Court (1979) 24 Cal.3d 890, the California Supreme Court held that a plaintiff may seek punitive damages against a driver who chose to drive while intoxicated. Punitive damages punish the conduct rather than compensate the loss, they sit outside the policy limits, and the threat of them changes how an insurance adjuster values your file from the first phone call.
Ordinary negligence claims carry no such exposure. This is the single largest practical difference between a rear-end collision and a drunk driving collision.
Who else can be held responsible
California Civil Code § 1714 blocks most claims against the bar or host who served the alcohol, treating the drinking rather than the pouring as the cause. One exception survives: Business and Professions Code § 25602.1 permits a claim against a licensed establishment that served an obviously intoxicated minor who then caused injury.
Where the driver worked at the time, or drove a company vehicle, an employer may share liability.
Two deadlines that end claims
You have two years from the collision to file a personal injury lawsuit under Code of Civil Procedure § 335.1.
If a government vehicle or a public employee was involved, you have six months to file an administrative claim under Government Code § 911.2. Missing that one ends the case before a court ever sees it.
When the drunk driver carries minimum coverage
California requires drivers to carry $30,000 per person in bodily injury liability. A drunk driving crash routinely produces hospital bills beyond that figure within the first week.
Your own uninsured and underinsured motorist coverage fills the gap, and the claim goes to your own insurer. Those policies carry notice requirements and arbitration clauses that work against anyone who waits.
DUI Statistics in California
California recorded 110,017 DUI arrests in 2021, according to the 32nd Annual Report of the California DUI Management Information System published by the DMV. Arrest counts have fallen by roughly half since 2010.
Alcohol-impaired crashes killed 1,311 people in California in 2024, which is 34% of the 3,876 traffic deaths recorded in the state that year, per the National Highway Traffic Safety Administration. Only Texas recorded more alcohol-impaired fatalities.
Close to 70% of DUI arrests in California result in a DUI conviction, according to DMV conviction data compiled through the DUI-MIS.
Alcohol-involved crashes cost the United States $68.9 billion in direct economic losses in 2019, covering medical treatment, lost wages, property damage, and emergency response, per NHTSA’s comprehensive crash cost study.
What the drunk driver who hit you is facing
These are the criminal penalties the driver faces. None of this money goes to you. Fines are paid to the court, and a judge who orders restitution typically covers a portion of documented medical bills over a payment schedule that runs for years. Your compensation comes from the civil claim.
First-Time DUI Offense:
- Fines: Up to $1,000, plus additional penalty assessments, which can substantially increase the total amount.
- License Suspension: 6 months (plus a possible administrative suspension by the DMV).
- Probation: 3 to 5 years of informal probation.
- Jail Time: 48 hours to 6 months in county jail (may be converted to community service in some cases).
- DUI Education Program: Completion of a 3-month DUI school (longer if BAC was particularly high).
- Ignition Interlock Device (IID): Installation of an IID for 6 months in some cases.
Second-Time DUI Offense:
- Fines: Up to $1,000, with additional penalty assessments.

Aggravating Factors
Certain facts raise the penalties even on a first offense: a BAC of 0.15% or higher, refusal of a chemical test, a child in the vehicle, and involvement in a collision that injured someone. That last one matters to your case. An injury-related DUI is charged under Vehicle Code § 23153 rather than § 23152, and the facts the prosecutor develops to prove it tend to support the civil claim you file.
Call a Thousand Oaks drunk driving accident lawyer
The other driver’s insurance company usually calls within a few days of the crash. The adjuster will sound friendly and will ask you to describe what happened on a recorded line. Months later, those same answers show up in a letter explaining why your injuries were not as serious as your doctors say.
A drunk driving accident lawyer in Thousand Oaks takes that call instead of you. At Bojat Law Group, we start by requesting the arrest report and the chemical test results from the agency that worked the scene. If the driver had been drinking somewhere before the crash, we send preservation letters to those bars and restaurants right away, because most of them record over their footage within a few weeks. We also follow the criminal case as it moves through court, since what the driver admits in front of a judge can be used in your civil claim. Where the facts support it, we ask for punitive damages on top of your medical bills and lost income.
We handle these cases in Thousand Oaks, Westlake Village, Woodland Hills, Oxnard, and Bakersfield.
