Motorcycle accident claims: helmets, fault and insurance

Why motorcycle claims are different#

The legal rules are the same ones that apply to car crashes: the person who caused the crash is responsible, and your share of the blame can reduce what you recover. What changes is the size of the harm. Per mile traveled, motorcyclists die at almost 27 times the rate of people in passenger cars, and NHTSA counted 6,228 motorcyclists killed in 2024.

That has three effects on a claim:

• Losses are often larger than the other driver's insurance. A serious injury can quickly pass a minimum policy limit, which makes your own coverage more important.
• Fault is fought over closely. Insurers look hard at speed, lane position and visibility, because under comparative negligenceComparative negligence. A rule that splits blame between the people involved and cuts your recovery by your own share of fault. Glossary every percentage point of fault reduces the claim.
• Insurance rules can differ. Some state no-fault rules treat motorcycles differently from cars, as explained below.

The general steps are covered in our guide to car accident claims; this page focuses on what is different for riders.

Common crash patterns#

NHTSA's crash data point to one pattern above all. In 2024, in 45% of fatal crashes between a motorcycle and one other vehicle, the other vehicle was turning left while the motorcycle was going straight, passing or overtaking.

Evidence that helps in these cases includes the final positions of the vehicles, damage to the front of the motorcycle and the side of the car, video from traffic or shop cameras, and witnesses who saw the light. Single-vehicle crashes are different: if a pothole, loose gravel or a missing sign caused the crash, a government agency may be responsible, and claims against public bodies come with short notice deadlines. In Texas, for example, notice is due within 6 months.

Helmet laws by state#

Helmet laws differ widely. Washington, DC and 17 states require helmets for all riders. Illinois, Iowa and New Hampshire have no helmet law for riders of any age. Most other states require helmets only for younger riders, typically those under 18 or under 21, and some add conditions:

• Florida: riders over 21 may go without a helmet only if they are covered by insurance with at least $10,000 in medical benefits for motorcycle crash injuries.
• Texas: riders 21 or older who have completed an approved motorcycle safety course or are covered by a health plan for motorcycle-crash injuries may ride without one. See the Texas guide for the state's other crash rules.

Helmet use differs sharply with the law. In states without a universal helmet law, 48% of motorcyclists killed in 2024 were not wearing helmets, compared with 11% in states with one (based on known helmet use).

Does riding without a helmet affect a claim?#

It depends on your state, and the rules are not uniform. A few points hold in most places:

• A helmet rarely has anything to do with who caused the crash. Not wearing one does not make you responsible for a driver turning in front of you.
• The argument is about the injuries. Where the issue is allowed, the other side usually argues that a helmet would have prevented or reduced a head injury, so damages for that injury should be lower.
• States treat the evidence differently. Some states let a jury hear that a rider wore no helmet and weigh it, some limit that evidence, and the answer can depend on whether the rider was breaking the state's helmet law.

An adjuster may raise the helmet question in negotiations whatever the local rule. A licensed attorney in your state can tell you how your state's courts treat it.

Insurance for motorcycle crashes#

The at-fault driver's liability insurance is the main source of money when another driver caused the crash. Your own motorcycle policy can fill gaps through uninsured motorist coverageUninsured motorist coverage. Coverage under your own policy that pays when the at-fault driver has no insurance, or too little. Glossary, medical payments coverageMedical payments coverage (MedPay). Optional or required coverage on your own auto policy that pays medical bills after a crash, up to a set limit, whoever caused it. Unlike PIP, it usually does not pay lost income. Glossary and, in some states, personal injury protectionPersonal injury protection (PIP). Coverage under your own policy that pays medical bills and some lost income after a crash, whoever caused it. Glossary:

PIP is where motorcycles are most often treated differently, and no-fault states do not all follow the same rule:

• Florida: the no-fault law defines a motor vehicle as a self-propelled vehicle with four or more wheels, so a motorcycle falls outside it, and riders cannot count on PIP as car occupants can.
• Michigan: a motorcyclist hurt in a crash involving a car or truck claims PIP benefits first from the insurer of the owner or registrant of the motor vehicle involved.

Evidence in a motorcycle claim#

Save the motorcycle in its damaged state if you can, along with your helmet, jacket, gloves and boots. Damage to gear helps show how the crash happened and how hard you were hit. Photograph the bike, the other vehicle, the road surface and any skid or scrape marks before they are cleaned up.

Get the names of witnesses and ask nearby businesses for camera footage early. Keep every medical record and bill, and a short journal of pain, sleep and missed activities. The claim process guide explains how this evidence is used in a demand and in negotiation.
