DUI vs DWI: Which One Does Idaho Actually Charge?

If you have been looking up drunk driving charges, you have probably seen two terms used almost interchangeably: DUI and DWI. They sound like different offenses, and people often wonder which one Idaho uses and whether one is worse than the other.

Here is the simple answer for Idaho.

Idaho uses DUI, not DWI

In Idaho, the charge is DUI, which stands for driving under the influence. You will not be charged with a DWI in Idaho. DWI, which usually means driving while intoxicated or driving while impaired, is a term used in some other states.

So if you searched for a DWI lawyer in Idaho Falls, you are really looking for a DUI defense attorney. The terms point to the same kind of case here.

What DUI covers in Idaho

Idaho DUI law under Idaho Code § 18-8004 generally covers operating a vehicle while impaired by alcohol, drugs, or other substances, or with a blood alcohol concentration at or above the legal limit. That means a DUI is not only about alcohol. You can be charged based on drugs, including prescription medication, if the state believes it impaired your driving.

The state still has to prove its case beyond a reasonable doubt. Impairment, the traffic stop, and the testing can all be challenged.

Why the wording still matters

Even though Idaho only uses DUI, the difference in terms can cause confusion when you are reading about your rights. Advice written for a DWI state may not match Idaho law on testing, license suspension, or penalties. When you are researching, make sure the information is specific to Idaho.

It also matters because the labels do not change how serious the charge is. A DUI in Idaho can carry jail time, license suspension, and a permanent record, and repeat or injury cases can become felonies.

Getting Idaho-specific help

The most important thing is not the acronym. It is getting advice that fits Idaho law and the local courts. Idaho has a separate administrative license suspension process with its own deadline, and the criminal case runs alongside it.
