Licensing Requirements
Class M License Requirements
Obtaining a motorcycle license in Idaho requires several steps, similar to the process in Wyoming. Riders must secure a valid driver’s license with a motorcycle endorsement or instruction permit. The process includes passing a DMV motorcycle written test, which costs $5.00. A skills test is mandatory unless waived through qualifying courses.
Age and Educational Requirements
Idaho sets the minimum riding age at 15 years old. Riders under 17 must complete approved driver education before motorcycle training. Those under 21 face additional requirements, including a mandatory motorcycle safety course.
Instructional Permits (MP License)
New riders start with an MP License, which comes with specific restrictions:
- Daylight riding only
- No passengers allowed
- Freeway riding prohibited
Helmet and Safety Equipment Laws
Unlike Nevada, Idaho’s helmet laws are less stringent. Helmets are only mandatory for riders under 18, following the universal helmet law repeal in 1978.

All motorcycles must meet federal safety standards and maintain clear handlebar operation without interference from transported objects.
As you plan your rides through the Gem State, remember that motorcycle laws can change at state borders. While Idaho’s regulations might seem more relaxed compared to Washington‘s comprehensive requirements or Oregon‘s stricter helmet laws, they’re designed to balance rider freedom with public safety. Riders venturing into neighboring Montana or Nevada should familiarize themselves with local regulations, as requirements for equipment, licensing, and safety gear can vary significantly. Whether you’re a resident or just passing through, staying informed about these laws ensures a safe and legal riding experience in Idaho and beyond.
