If you’ve found yourself charged with a DUI in Idaho, you are not alone. You may be wondering, “what are the laws surrounding DUIs?” Idaho has some of the toughest DUI laws in the United States, so a DUI charge requires immediate action to fully protect all of your rights.

We are here to help guide you through what can be a very complicated process.
First, let’s cover the penalties for a DUI charge. The legal limit varies in Idaho.
- Over the age of 21 – .08% blood alcohol content (BAC).
- Under the age of 21 – Idaho is a Zero Tolerance state, meaning the legal limit for those under 21 is .02% BAC.
- Commercial Vehicles – .04% BAC.
If you are found to be over these limits, you are subject to the penalties outlined in Idaho Code 18-8005.
Idaho DUI, First Offense

- Up to 6 months in jail
- Fines up to $1,000
- 90-180 day suspension of driver’s license.
- Mandatory ignition interlock device, more commonly known as an in-car breathalyzer. This system locks the ignition and administers a breath alcohol test before unlocking the ignition and allowing the car to start. The driver is responsible for all costs associated with purchasing, installing, and maintaining ignition interlock. This penalty was put into place in 2019.
Idaho DUI, Second Offense

Idaho DUI, Third Offense

A DUI with a BAC of .20% or higher is considered an excessive DUI in the state of Idaho and is subject to enhanced penalties. Even if it is a person’s first DUI, the penalties include a misdemeanor violation, mandatory 10 days in jail that could potentially be increased up to a year, fines up to $2,000, and a mandatory one-year license suspension. If a driver is charged with two excessive DUIs in 10 years, the charge is automatically a felony rather than a misdemeanor.
