Idaho DUI on a Bicycle or an E-Scooter?
With Boise being such a bike-friendly city, it's not uncommon for some people to ride bikes or e-scooters home from the bars. Although this seems safer than operating a motor vehicle, it leads to the question of whether drinking and cycling or e-scootering is even legal. And the answer to that question really depends on the circumstances.
Drinking and Cycling in Idaho
Despite rumors, you cannot be charged with a DUI on a bike in Idaho that is solely moved by human power. This is because Idaho's DUI statute only applies to individuals in "actual physical control of a motor vehicle," and "vehicles moved solely by human power" are expressly excluded from the definition of a motor vehicle (see Idaho Code 18-8004 and 49-123(1)(h)).
Although you cannot be charged with a DUI while riding on a bicycle, you can be charged with other offenses, such as public intoxication. Like a DUI, public intoxication is a misdemeanor that can result in a fine and/or jail time. A person can be convicted of public intoxication in Idaho if they are on a public street or highway while under the influence of alcohol or any drug to a degree that renders him or her a hazard. What qualifies as a hazard depends on the circumstances, but the language of the statute is broad and incorporates a wide range of behavior.
If you choose to hop on your bicycle after having a few drinks at night, be aware that you can be stopped for lacking the proper safety equipment, such as a white front facing headlight and a rear red reflector. Both of these are required by state law, and cyclists have been stopped in Boise for lacking them. While proper cycling equipment is probably not a priority to most people, having it may prevent you from being cited for an infraction and, if applicable, public intoxication.
Drinking and E-Scootering in Idaho
Now, the tougher question: can you be charged with a DUI while riding on an e-scooter in Idaho? Probably not. Going back to the definition of a motor vehicle, the legislature does not consider "vehicles that are specifically exempt from titling or registration requirements" to be motor vehicles (see Idaho Code 49-123(1)(h)). In January of this year, the Idaho Department of Transportation issued the following guide indicating that e-scooters have no titling or registration requirements: https://itd.idaho.gov/wp-content/uploads/2019/01/2-Wheel_and_3-Wheel_Vehicle_Requirements.pdf. This leads us to believe you cannot be charged with a DUI while riding on an e-scooter in Idaho. Like drinking and cycling, however, drinking and e-scootering won't prevent you from being cited for public intoxication if you're considered a hazard.
