What Is the Difference Between DUI and DWI?
The charge depends on the state of your arrest.
DUI and DWI: Learn the Basics of Impaired Driving
If you are facing an impaired driving charge, it is important to understand the difference between DUI and DWI. While the terms are often used interchangeably, some states treat them as different offenses with different meanings and penalties.
This guide explains how DUI and DWI differ, how states use each term, and why the distinction may affect your case.
DUI vs. DWI: What You Need to Know
DUI stands for “driving under the influence.” DWI stands for “driving while intoxicated” or “driving while impaired.” The terms sound similar, but they don’t always mean the same thing, and the difference can matter a great deal depending on where you live and what charges you face.
The key difference is how each state uses these terms. Some states use DUI. Some use DWI. A few states use both, but they mean different things by them.
In most states, DUI and DWI are the same charge. The name just depends on where you live. If you’re in California, you’ll see DUI on your paperwork. Other states prefer DWI. Neither term is worse than the other by default.
When a State Uses Both Terms
Some states use both DUI and DWI, and treat them as separate charges. In those states, DWI often means a higher blood alcohol level or more serious impairment. DUI may refer to a lesser level. This matters for penalties.
Laws vary by state. Each state writes its own rules. That’s why the terms differ. The crime is the same — impaired driving — but the label changes based on local law.
Here’s a quick list of the states that treat DWI and DUI as different charges:
-
Arizona: DUI and DWI differ based on the substance used and how impaired the driver is.
-
Colorado: DUI means the driver is too impaired to drive safely. DWAI means the driver is less able than normal to drive.
-
Maryland: DUI is the more serious charge, often at 0.08% or higher. DWI is a lesser offense with lower impairment levels.
-
Minnesota: The state has several impaired driving levels, each with its own rules and penalties.
-
New York: In New York, DWI applies to drivers with a BAC of 0.08% or higher. DWAI applies to lower levels (0.05%–0.07%) or drug-related cases.
-
Oklahoma: DUI covers alcohol or drugs, while DWI applies to lower levels of impairment with different penalties.
-
Texas: DWI usually applies to adults with a blood alcohol level of 0.08% or higher. DUI often applies to minors with any alcohol in their system.
PRACTICE AREAS
How These Charges Work in Real Life
If you need help understanding the differences between DUI and DWI, real-life examples can make it easier to see how these charges are applied.
Say you’re pulled over after two drinks. The officer gives you a breathalyzer test. Your blood alcohol level comes back at 0.09%. In California, that’s a DUI. In Texas, that same result could be charged as a DWI. Same facts. Different label.
What If a State Uses Both?
In states like Texas, a DWI is the standard charge for adults with a blood alcohol concentration (BAC) of 0.08% or more. A DUI may apply to drivers under 21 with any detectable alcohol. The distinction matters because penalties might differ.
Drugs Count Too
Both DUI and DWI can apply to drug use, not just alcohol. Prescription drugs, marijuana, or illegal substances can all lead to a charge. You don’t need a BAC above the legal limit. Impairment alone is enough in most states.
How Penalties Compare Between DUI and DWI
The penalties for DUI and DWI can be serious and often increase with each offense. Understanding how these penalties compare helps you see what’s at stake.
First-Time Offense
A first charge —whether it’s called DUI or DWI— usually brings fines, a license suspension, and possible jail time. In California, a first DUI can mean up to six months in jail, fines up to $1,000, a license suspension of up to six months, mandatory DUI school, and probation of up to 5 years.
Moreover, a first-time DUI in California is usually considered a misdemeanor.
Repeat Offenses
Each repeat offense raises the stakes. A second or third charge brings longer jail time, higher fines, and longer license loss.
In California, a third DUI offense within 10 years may result in 120 days to 1 year in jail, fines ranging from $390 to $1,000, a three-year license suspension, and 3 to 5 years of probation.
Some states require ignition interlock devices after repeat offenses.
Felony Charges
Most first-time DUI or DWI charges are misdemeanors. In California, a DUI becomes a felony if someone is injured or killed, if a child was in the car, if you have multiple prior DUI convictions, or if you already have a prior felony DUI on your record.
Felony DUI charges in California may result in:
- Prison Time: 16 months to 3 years in state prison.
- Fines: $1,000 to $5,000 fines plus restitution to victims
- License Suspension: 3-year suspension
- Probation: 3-5 years
- DUI Education Program: Required completion
- Ignition Interlock Device: Required installation in vehicle
- Criminal Record: Permanent felony conviction on record
Additionally, California courts often count out-of-state DWI convictions as prior DUI offenses. This can lead to harsher penalties if you face a new DUI charge in California, depending on how closely the other state’s law matches California’s DUI laws.
Such detailed information highlights the importance of hiring an experienced DUI attorney.

Frequently Asked Questions
1. Does California use DUI or DWI as its official charge?
California uses DUI — driving under the influence — as the official legal term. You will not see DWI on a California charge sheet. The state charges drivers under Vehicle Code Section 23152 for impaired driving. This covers alcohol, drugs, or a mix of both. Some other states use DWI, but in California, DUI is the standard term across all counties.
2. Can you be charged with both DUI and DWI in the same state?
Most states use one term or the other, not both. A few states use both terms, but they mean different things there. One may refer to alcohol impairment; the other to drug impairment. In California, only the DUI label applies. There is no separate DWI charge.
3. Does a DUI from another state count as a prior DWI in California?
Yes. California can treat an out-of-state DUI or DWI as a prior offense. If you were convicted in a state that uses DWI, California courts may still count it. This matters because prior offenses increase penalties under California law. A second or third DUI charge in California carries harsher consequences, including longer license suspensions and possible jail time.
4. Is a DWI worse than a DUI on a criminal record?
The label itself does not determine the seriousness of the charge. What matters is the underlying facts — your BAC level, whether anyone was hurt, and your prior record. In states that use both terms, one may carry higher penalties than the other. In California, the DUI charge level — misdemeanor or felony — is what shapes the long-term impact on your record and your future.
5. Does a DUI conviction in California show up as a DWI on a background check?
No. A California conviction will appear as a DUI. Background checks reflect the charge as filed in the state where it occurred. If you were convicted in California, it shows as a DUI. If you were convicted in a state that uses DWI, it shows as a DWI. The terms are not interchangeable on official records. Employers or licensing boards may treat both charges similarly, regardless of the label used.
