Idaho Motorcycle Laws Require Bikers to Obtain a Licence Endorsement
All drivers in Idaho must have a valid driver’s license. You must also obtain a motorcycle endorsement (Class M) to operate a motorcycle. According to the Idaho Motorcycle Rider’s Handbook, if you surrender an out-of-state Class M license or more than 25 months have passed since you received an endorsement, you must first pass a motorcycle knowledge and skills test. If you are under 21, you must pass the knowledge test and a rider training course.
Anyone riding a motorcycle, motor-driven cycle, motor scooter, or motorbike must have an endorsement.
Idaho Motorcycle Insurance Laws
Drivers in Idaho, including motorcycle riders, must carry auto liability insurance to pay for accidents if they are at fault. According to the Idaho Department of Insurance, the required minimums are $25,000/$50,000 in bodily injury liability per person/per accident and $15,000 in property damage liability.
Insurance policies must also provide uninsured and underinsured motorist (UM/UIM) bodily injury coverage unless you reject it in writing.

Idaho Helmet Laws
Idaho Statutes § 49-666 states that anyone under age 18 must wear a helmet when operating a motorcycle, motorbike, ATV, or UTV on public property. Helmets are not required on private property or for individuals over 18.
Idaho Motorcycle Laws Regarding Lane Sharing and Lane Splitting
Lane filtering is the practice of picking your way through slow-moving traffic. Lane splitting is when motorcycle riders weave in and out of moving traffic, often by traveling along the centerline. Both lane filtering and lane splitting are illegal in Idaho.
Motorcyclists have the right to use a full traffic lane, so it is illegal for cars to share a lane with motorcycles. Additionally, it is also illegal for two riders to share a lane.
It is Against the Law for Any Motorcyclists or Vehicle Operator to Drink and Drive
No driver may operate a motorcycle, car, truck, or any other type of motor vehicle while intoxicated. According to Idaho Statutes § 18-8004, the law regards most motorists as legally intoxicated if they have a blood alcohol concentration (BAC) of 0.008 or higher.
Drinking and driving can incur civil and criminal penalties.

Schedule NowA Violation of the Idaho Traffic Laws Can be Ground for a Motorcycle Accident Claim
If you suffer injuries in a motorcycle accident, Idaho motorcycle laws and traffic laws will matter in your case. If another driver broke the law or otherwise acted negligently, they may be financially liable for your crash damages. Examples include:
- Driving without a license
- Driving without insurance
- Driving a vehicle that lacks proper equipment
- Driving under the influence of drugs or alcohol
- Speeding
- Tailgating
- Illegally passing
- Crowding another driver’s lane
- Failing to stop at a stop sign or red light
- Driving recklessly or aggressively
However, if you violated the law or made a driving error, you may bear some responsibility, which can affect your claim for compensation.
Idaho Statutes § 6-801 states that you can seek damages from those at fault if you are not more than 50 percent liable for an accident. Any percentage of liability below 50 percent that the court assigns you will reduce your damages by that amount. If it finds you are more than 50 percent liable, you cannot recover any damages. Insurance companies know the law, so it will also affect settlement offers.
Do You Need a Lawyer?
No law requires you to hire a lawyer to handle a motorcycle crash claim. However, a lawyer can work to investigate your case and prove negligence while you focus on healing. An Idaho personal injury attorney with our firm can also fight back against allegations that you broke the law or are somehow at fault, which can reduce your settlement or negate your right to compensation.
Recoverable Motorcycle Accident Damages
If a liable party caused your crash, in general, you can seek damages for the following:
- Current and future medical expenses
- Lost wages and employment benefits
- Lost future earning capacity
- Motorcycle repair or replacement costs
- Household services
- Physical, mental, and emotional pain and suffering
- Wrongful death of a loved one
You do not have unlimited time to recover your losses. You should file insurance claims immediately. If you must take legal action, Idaho Statutes § 5-219 allows two years to file a personal injury or wrongful death lawsuit. If time expires, you likely cannot take your case to court, and you will lose bargaining power over the insurance company.
