The Difference Between DWI and DUI
If you were pulled over in California and charged with driving under the influence. You are likely confused about the terms being used and what they really mean for your future. You might have heard people call it a DUI or a DWI or even refer to it as drunk driving or impaired driving and you are probably wondering whether there is a difference or whether one charge is more serious than the other. When your freedom, your license and your reputation are on the line and these details matter. It is important for you to understand them and this is the first step toward protecting yourself and moving forward with confidence.
In California, DUI and DWI do not mean the same thing as they do in some other states. California law does not actually use the term DWI in any official way. Instead, the legal system here uses DUI to describe most offenses involving alcohol or drug impairment behind the wheel and that distinction matters especially when you are reading your charges, talking to a lawyer or facing a judge who expects you to understand the seriousness of what you are accused of.
Before we go further, would you like to speak with a former district attorney about your case?
What DUI Really Means in California
In California, DUI stands for driving under the influence and it is the official term used in all criminal statutes related to alcohol or drug-impaired driving. The most common charges fall under Vehicle Code 23152(a) which makes it illegal to drive while under the influence of alcohol and 23152(b) which makes it illegal to drive with a blood alcohol concentration of 0.08 or higher regardless of whether you appear intoxicated. Both charges can be filed together and often are, which means you can face two DUI counts from the same incident even if no one was hurt and even if this is your first offense.
DUI also covers drug-related impairment including illegal drugs, prescription medication or even over-the-counter substances if they impair your ability to drive safely. Under Vehicle Code 23152(f) you can be charged with DUI for driving under the influence of any drug and that includes marijuana even if you have a valid medical card or you used it legally. In these cases, the prosecution does not need to prove a specific BAC. Instead, they rely on officer observations, field sobriety tests and chemical testing when available to argue that your mental or physical abilities were impaired.
What About DWI?
DWI stands for driving while intoxicated or driving while impaired and it is a term used in many other states like Texas or New York to describe similar conduct. Some states use DWI for alcohol-related charges and reserve DUI for drug impairment or vice versa. In California, DWI is not a term that appears in the legal code or in formal court documents. You may still hear officers or media reports use DWI as a general reference but legally speaking in California, the charge is always classified as DUI.
That said, the use of different terms can still create confusion especially if you are dealing with an out-of-state license or prior offenses from another jurisdiction where DWI was the formal charge. In these cases, your attorney will need to carefully review the prior conviction to determine whether it counts as a DUI prior under California law, which can affect sentencing and eligibility for diversion or reduced charges.
Does the Difference Matter?
If you were arrested in California and received a notice to appear in court for DUI, you do not need to worry about whether it is called DWI in other places. What matters is the specific code section you are charged under and the evidence against you including how your case is handled from the moment of arrest through the final hearing. The key distinction is not the letters themselves but the facts of your case and how those facts align with California’s DUI statutes.
Where the difference can matter is when someone is facing charges in multiple jurisdictions or trying to understand how a prior DWI conviction from another state affects their California DUI case. For example, if you had a DWI in New York and are now charged with DUI in Los Angeles, the prosecutor may try to use the prior DWI to enhance the penalties in your current case. Whether they can do that depends on whether the elements of the out-of-state conviction match California’s legal definition of DUI and this is something that must be carefully evaluated by your defense lawyer.
The Consequences Are the Same
Regardless of what it is called, the consequences of a DUI in California are serious and can include jail time, license suspension, probation, mandatory DUI school, fines and the installation of an ignition interlock device on your vehicle. Even a first offense can have long-term consequences for your job, your insurance rates, and your ability to travel or maintain a professional license.
The penalties become more severe if there are aggravating factors such as a high BAC, a refusal to submit to testing, a minor in the vehicle or if the incident involved an accident with injuries. In those cases, the charge can be elevated from a misdemeanor to a felony and that means state prison time, formal probation, and a permanent felony conviction on your record.
Because California uses DUI as the official charge, whether your case involves alcohol, drugs or both, the name does not change the stakes. You are still facing criminal prosecution and you still need a defense strategy that takes into account every detail of the stop, the testing, the arrest and the evidence collected against you.
DUI and DMV Consequences
In addition to the criminal case, there is also a separate process through the California Department of Motor Vehicles, which can suspend your license independently of what happens in court. If you are arrested for DUI and either refuse testing or test at 0.08 or higher, the officer will confiscate your license and issue a pink temporary license that is valid for only thirty days. You have just ten days from the date of arrest to request a DMV hearing to contest the suspension and if you miss that deadline your license will be automatically suspended even if you later win in court.
This DMV process is not concerned with guilt or innocence in the legal sense. It is a civil administrative action and the burden of proof is much lower. Still, it can have a huge impact on your ability to work or care for your family and the outcome of the hearing can affect whether you need an ignition interlock device or whether you qualify for a restricted license that lets you drive to work or school.
