Utah Motorcycle Accident Laws (2026): Deadlines & Helmets

A motorcycle crash in Utah is handled differently than a car crash in two ways that surprise riders: Utah is a no-fault (PIP) state for cars, but motorcycles sit outside that system, and Utah is one of the few states where lane filtering is actually legal. On top of that sit the usual questions about the deadline to sue, the fault rule, and the helmet law. This guide explains how Utah answers each one. It is general legal information and attorney advertising, not legal advice, and reading it does not create an attorney-client relationship.

This page is part of our Motorcycle Accident Laws by State series. Deadlines are firm and every crash is different, so treat the figures below as a starting point and confirm the current law before relying on it.

The deadline to sue in Utah

The statute of limitations is the legal deadline to file a lawsuit. In Utah, a personal injury claim from a motorcycle crash generally must be filed within four years of the crash under Utah Code 78B-2-307. That is a relatively generous window, but it comes with a trap: a wrongful death claim must be filed within two years of the death under Utah Code 78B-2-304, not four. Families dealing with a fatal crash often assume they have the longer period and do not. A court will dismiss a late case regardless of its merits, so both deadlines should be confirmed at the start.

Fault rule: modified comparative fault with a 50 percent bar

Utah uses modified comparative fault under Utah Code 78B-5-818. An injured rider can recover only if the rider's percentage of fault is less than the fault of the defendant or combined defendants, and the award is reduced by the rider's own percentage. In practical terms the defendants' fault must exceed the rider's, so a rider who is exactly 50 percent at fault generally recovers nothing, while a rider who is 49 percent at fault recovers 51 percent of the damages. A rider found 20 percent at fault with $100,000 in damages recovers $80,000.

This matters in motorcycle cases because insurers often try to push fault onto the rider, leaning on a bias that riders are reckless. Crossing the 50 percent line does not just shrink the recovery, it eliminates it, so documenting the other driver's fault is critical.

No-fault, PIP, and why motorcycles are different

Utah is a no-fault state for cars. Car owners must carry personal injury protection (PIP), and an injured driver normally turns to PIP first and can only step outside the system to sue for general damages such as pain and suffering after meeting a threshold, which under Utah Code 31A-22-309 includes more than $3,000 in medical expenses or a serious injury such as permanent disability, permanent impairment, dismemberment, a bone fracture, or permanent disfigurement.

Motorcycles are the major exception. Under Utah Code 31A-22-309, a motorcycle is not required to carry PIP and is not covered by the no-fault system. That cuts two ways. A motorcyclist usually has no PIP to fall back on for early medical bills. But because the rider is outside the no-fault system, the $3,000 threshold does not stand in the way: an injured motorcyclist can pursue the at-fault driver directly for all damages, including pain and suffering, without first clearing the no-fault threshold. Recovery typically comes from the at-fault driver, the rider's own uninsured or underinsured motorist coverage, or medical-payments coverage bought on the motorcycle policy.

Helmet law: partial

Utah has a partial helmet law under Utah Code 41-6a-1505. Only riders and passengers under 21 are required to wear protective headgear; the age was raised from 18 to 21 in 2017. Riders 21 and older may legally ride without a helmet. Even where the law allows it, riding without a helmet greatly increases the risk of a serious head injury.

Can not wearing a helmet hurt your case (the helmet defense)

Utah is unusually protective of riders here. Utah Code 41-6a-1505 states that the failure to wear protective headgear does not constitute contributory or comparative negligence and may not be introduced as evidence in any civil case on the issue of negligence, injuries, or the mitigation of damages. In plain terms, a defendant cannot use a rider's lack of a helmet to reduce a damages award. That makes Utah different from many states, where a helmet defense is at least available in head-injury cases. The bar applies whether or not the rider was old enough to ride without a helmet.

Lane filtering is legal in Utah

Utah is one of the few states that allows lane filtering. Under Utah Code 41-6a-704, a motorcycle may filter between stopped vehicles under specific conditions: the roadway must have a posted speed limit of 45 mph or less and two or more lanes traveling in the same direction, the vehicles in those lanes must be stopped, and the motorcycle may not travel faster than 15 mph while filtering. Filtering is not allowed on freeways. This is filtering past stopped traffic, not the open-traffic lane splitting that California allows. Utah's filtering provision carries a sunset clause and is scheduled to be repealed on July 1, 2027 unless the legislature extends it or makes it permanent, so riders should confirm it remains in effect and follow the exact conditions, since filtering outside those limits is not protected and can support a fault argument.

Damage caps and minimum insurance

Utah does not cap compensatory damages, such as medical bills, lost income, and pain and suffering, in an ordinary motorcycle-injury or wrongful-death case. (Utah caps noneconomic damages only in medical malpractice cases, not ordinary auto cases.) On insurance, Utah raised its minimum liability coverage to 30/65/25, which is $30,000 per person and $65,000 per accident for bodily injury, plus $25,000 for property damage, effective January 1, 2025. Even those minimums can fall short of a serious motorcycle injury, which is why uninsured and underinsured motorist coverage matters.

Why motorcycle cases are different

Motorcycle crashes tend to cause far more serious injuries than car crashes because a rider has so little protection, which means higher medical bills and a tougher insurance defense. Riders also face the no-fault and fault rules above, plus a documented bias against motorcyclists among some jurors and adjusters. The classic crash is a car turning left across an oncoming motorcycle, with the driver claiming they never saw the bike. With a 50 percent fault bar in play, physical evidence and a clear record of the rider's lawful conduct carry real weight.

Evidence and how to evaluate your options

If you or a family member was hurt in a Utah motorcycle crash, get medical care and keep the records, obtain the crash report, and photograph the scene, the bike, and your gear. Note the other driver's information and any witnesses. Then speak promptly with a licensed Utah attorney, both because of the deadlines (four years for injury, but only two for wrongful death) and because early evidence fades. 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 or amount can be promised; every case turns on its own facts. This article is general information, not legal advice.
