Motorcycle Accident Laws in North Dakota (2026): Deadlines

A North Dakota motorcycle crash is a personal injury case, but it sits at an unusual intersection of rules. North Dakota is a no-fault auto state, yet motorcycles are generally treated as outside that no-fault system, which changes how an injured rider gets medical bills paid. Add an unusually long six-year deadline to sue, a 50 percent comparative-fault bar, and a partial helmet law, and the rider's path to recovery has several moving parts. This guide explains how those rules work. It is general legal information and attorney advertising, not legal advice.

The deadline to sue in North Dakota

North Dakota gives an injured person an unusually long window to file a personal injury lawsuit. Under N.D.C.C. section 28-01-16, the statute of limitations for an injury to the person not arising on contract is six years from the date of injury, which is far longer than the two- or three-year deadlines common in most states. A wrongful death claim is the major exception: it must be brought within two years, generally measured from the date of death, under section 28-01-18. The long six-year window for injury claims does not mean waiting is wise, because evidence fades and witnesses move, and claims against a government entity can carry separate, shorter notice deadlines.

Fault rule: modified comparative fault with a 50 percent bar

North Dakota follows modified comparative fault under N.D.C.C. section 32-03.2-02. Your contributory fault does not bar recovery unless it is as great as the combined fault of all the other people who contributed to the injury, and any recovery is reduced in proportion to your share of fault. In practice, this is a 50 percent bar: if you are 49 percent at fault, you recover 51 percent of your damages; if your fault is as great as the combined fault of everyone else, meaning roughly 50 percent or more, you recover nothing. Because the comparison is against the combined fault of all other parties, the math can matter in crashes involving more than one other driver.

For riders, this rule is why insurers routinely argue the motorcyclist shares blame. Pushing a rider to the 50 percent line is how a defendant tries to wipe out the entire claim, so documenting the other driver's fault is critical.

No-fault insurance and how motorcycles are treated

This is the rule that surprises many North Dakota riders. North Dakota is a no-fault auto state under the Auto Accident Reparations Act, N.D.C.C. chapter 26.1-41, which requires owners of motor vehicles to carry basic no-fault, or personal injury protection, benefits and provides up to $30,000 per person for economic losses regardless of fault. Motorcycles, however, generally do not meet the no-fault definition of a motor vehicle, so a motorcycle owner is not required to carry no-fault coverage and an injured motorcyclist usually cannot collect those basic no-fault benefits the way a car occupant could.

What this means after a crash is that a North Dakota motorcyclist typically recovers through the at-fault driver's liability insurance and through the rider's own medical payments, health insurance, and uninsured or underinsured motorist coverage, rather than through no-fault benefits. Because no-fault does not cushion the rider, the at-fault driver's limits and the rider's own coverage become especially important.

The no-fault threshold to sue for pain and suffering

North Dakota's no-fault system limits when an injured person can sue for noneconomic damages such as pain and suffering. To step outside no-fault and pursue those damages, the injury generally must be a serious injury, which N.D.C.C. chapter 26.1-41 defines to include death, dismemberment, serious and permanent disfigurement or disability beyond 60 days, or medical expenses in excess of $2,500. Most serious motorcycle injuries clear that threshold easily. And because an injured motorcyclist is generally outside the no-fault system to begin with, the threshold is often less of an obstacle for riders than it is for car occupants, though how it applies depends on the specific facts and is worth confirming with an attorney.

North Dakota helmet law

North Dakota has a partial helmet law under N.D.C.C. section 39-10.2-06. A person under 18 who operates or rides a motorcycle must wear protective headgear that meets department standards, and if the operator is required to wear a helmet, any passenger must wear one regardless of age. Riders 18 and older may legally ride without a helmet. North Dakota does not require eye protection by statute.

Helmet non-use and your case

Because adults may legally ride without a helmet in North Dakota, the question of whether non-use can be raised against an injured rider can come up. North Dakota does not have a statute that broadly bars a so-called helmet defense, so a defendant may try to argue that an adult rider who chose not to wear a helmet contributed to the severity of head injuries. Any such argument is governed by the comparative fault framework and turns on causation, meaning whether the lack of a helmet actually worsened the specific injuries, which usually requires expert evidence. How a court treats the issue is fact-specific and best evaluated by a North Dakota attorney on the records of the case.

Lane splitting and lane filtering

Lane splitting and lane filtering are not legal in North Dakota. Under N.D.C.C. section 39-10.2-04, a motorcycle is entitled to full use of a lane, but a rider may not operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles, and motorcycles may not be operated more than two abreast in a single lane. A rider who was splitting lanes at the time of a crash can expect that conduct to be raised in the comparative-fault analysis.

Damage caps and minimum insurance

North Dakota does not cap ordinary compensatory damages in a typical motorcycle injury case, so there is generally no statutory ceiling on medical expenses, lost income, or pain and suffering, subject to the comparative-fault rule and the no-fault threshold above. Certain specialized claims can have their own limits that a lawyer can flag where relevant. For the at-fault side, North Dakota requires minimum liability limits of $25,000 for bodily injury per person, $50,000 per accident, and $25,000 for property damage, along with uninsured-motorist coverage; no-fault coverage is not required for a motorcycle. Because these floors can be low relative to a serious motorcycle injury, the at-fault driver's actual limits and the rider's own coverage often determine what is collectible.

Why motorcycle cases are different and how to evaluate yours

Motorcycle crashes tend to cause far more serious injuries than car crashes, which means higher medical costs, larger claims, and a more aggressive insurance defense. North Dakota riders also face the specific issues above: the long six-year deadline that still rewards early action, the 50 percent fault bar, and the fact that no-fault benefits generally do not cover motorcyclists, which makes the rider's own coverage critical. A documented bias against motorcyclists among some jurors and adjusters is one more reason careful, contemporaneous documentation matters.

If you or a family member was hurt in a North Dakota motorcycle crash, get medical care and keep every record, obtain the crash report, photograph the scene, the bike, and your gear, and save the other driver's information and any witness contacts. Then speak promptly with a licensed North Dakota attorney, because early evidence is often decisive even with a long filing window, and because the no-fault and fault rules above can be tricky to navigate. Most motorcycle accident attorneys offer a free consultation and work on a contingency basis, meaning no upfront fee and payment only out of any recovery. No outcome can be promised, and reading this article does not create an attorney-client relationship.
