Is Driving While Impaired the Same as DUI?
Not all impaired driving charges are equal.
What Is the Difference Between Driving While Impaired and DUI?
If you are facing an impaired driving charge, it is important to understand that “driving while impaired” and “DUI” do not always mean the same thing. Some states use both terms and assign different meanings or penalties, while California generally uses DUI as the main charge.
This guide explains how the terms differ, how states apply them, and why the distinction can matter.
Driving While Impaired and DUI: Learn The Basics of These Two Concepts
These two terms describe similar behavior. Both mean driving after consuming alcohol or drugs. But they are not always the same charge under the law.
Driving while impaired means driving a vehicle after using alcohol, illegal drugs, prescription medicine, or over-the-counter drugs. This is both illegal and dangerous. It can slow your reaction time, reduce coordination, and affect judgment, often leading to deadly crashes.
DUI, or driving under the influence, means driving a vehicle after using alcohol, drugs, or medication. In the United States, a person is usually considered impaired if their blood alcohol level is 0.08% or higher.
Some states use both terms. Others use only one. The meaning depends on where you live. In California, the main charge is DUI, under Section 9: Alcohol and Drugs – California DMV (California Vehicle Code §23152). The state does not use DWI as a separate offense. But in other states, DWI and DUI can mean different things; sometimes one is more serious than the other.
Say two drivers are stopped in different states. Both had a few drinks. In one state, both face DUI charges. In another state, one may face DWI and the other DUI based on their blood alcohol level or behavior. Same facts. Different labels. Different outcomes.
PRACTICE AREAS
How Blood Alcohol Level Affects the Charge
In most states, a blood alcohol concentration (BAC) of 0.08% or higher triggers a DUI or DWI charge. This is called a per se violation. You do not need to show signs of impairment. The number alone is enough.
In California, the legal blood alcohol concentration (BAC) limit is 0.08% or higher for drivers 21 and older. Stricter limits apply: 0.01% for under 21, 0.01% for those on DUI probation, and 0.04% for commercial drivers.
Some states set a lower BAC for a lesser charge. For example, a BAC between 0.05% and 0.07% might result in a DWI instead of a DUI in New York and Colorado. The DWI may carry lighter penalties. It depends on the state’s laws. California residents should know the difference when driving outside the state.
California exchanges driving record information with most states through the Driver License Compact. If you get a DUI in another state, California can treat it the same as a local offense. The DMV may then suspend your California license based on that out-of-state conviction.
States That Treat Driving While Impaired (DWI) and DUI as Two Different Charges
- Texas: In Texas, DWI means driving while intoxicated, usually for adults with a blood alcohol level of 0.08% or higher. DUI usually apply to minors who have any amount of alcohol in their system.
- New York: New York uses DWI for drivers with a blood alcohol level of 0.08% or higher. It also uses DWAI for lower impairment, such as a level between 0.05% and 0.07%, or when drugs are involved.
- Oklahoma: Oklahoma has two offenses: DUI for alcohol or drugs, and DWI for a lower level of impairment, with different penalties.
- Colorado: The state of Colorado defines DUI as being too impaired to drive safely, while DWAI means the driver is less able than normal to drive.
- Maryland: Maryland authorities separate DUI and DWI by severity. DUI is more serious and often involves a level of 0.08% or higher, while DWI is a lesser offense with slightly lower levels.
- Arizona: Arizona law treats DUI and DWI as different charges depending on the substance used or how impaired the driver is.
- Minnesota: Minnesota has different categories of impaired driving, each with separate definitions and penalties based on the degree of impairment.
Moreover, impairment does not always require alcohol. Drugs — including prescription drugs — can lead to a DUI or DWI charge. If a substance affects your ability to drive safely, that may be enough. Officers assess your driving, speech, coordination, and eye movements.

Why the Charge Label Matters
A DUI often carries harsher penalties than a DWI in states that use both terms. This can mean more jail time, higher fines, or a longer license suspension. The exact difference depends on the state you’re driving in.
Both charges go on your record, regardless of where they happened and where you live. Out-of-state convictions follow you. So, you might be a California resident facing DWI charges in Arizona, even if California doesn’t distinguish between DUIs and DWIs; being convicted of a DWI in Arizona stays on your record.
Employers, landlords, and licensing boards can see them.
Speaking with a DUI attorney can help you understand what you are actually facing and what a realistic defense looks like.

Frequently Asked Questions
1. Can you get a DWI in California, or is it called a DUI?
California does not use the term DWI in its vehicle code. The state charges impaired drivers under DUI (driving under the influence) laws. Other states, like Texas and New York, use DWI as their primary term. If you were charged in California, your charge will appear as a DUI. The label on your charge depends entirely on the state where the incident occurred.
2. What is the difference between a DUI and a wet reckless in California?
A wet reckless is a reduced charge that may result from a plea deal in a DUI case. It still involves alcohol but carries lighter penalties than a standard DUI conviction. Insurance companies often still treat it like a DUI. A wet reckless can also count as a prior offense if you face another DUI charge later. It is not the same as being cleared of impaired driving.
3. Does a DWI from another state count as a prior DUI in California?
Yes, in many cases it can. California courts often treat out-of-state DWI convictions as prior DUI offenses. This means your penalties could increase if you face a new DUI charge in California. The exact impact depends on how closely the other state’s law matches California’s DUI statute. An attorney can review your record and explain what prior convictions may mean for your case.
4. Is impaired driving treated differently if drugs are involved instead of alcohol?
California’s DUI law covers both alcohol and drugs. You can face a drug DUI charge even if you have a valid prescription. The key question is whether the substance impaired your ability to drive safely. Drug DUI cases often rely on officer observations and chemical tests rather than a breathalyzer. The charge still falls under California’s DUI statute, not a separate impaired driving law.
5. Can you be charged with DUI in California if your BAC was below 0.08%?
Yes. California law allows a DUI charge even when your blood alcohol concentration is below the legal limit. If an officer believes your driving ability was impaired, that is enough to support a charge. This is sometimes called an impairment-based DUI. It is separate from the per se DUI charge tied to a 0.08% BAC or higher. Both types carry serious legal consequences.
