What to Do After a Motorcycle Accident in Guam
Motorcycle accidents on Guam can cause serious injuries and create urgent questions about medical care, evidence, insurance, and deadlines. This guide explains practical next steps and selected Guam rules, while recognizing that responsibility and coverage depend on the facts and the applicable policy.
Guam Motorcycle Laws and Helmet Requirements
Guam has a limited helmet rule, not a universal rule for every rider. Under 16 GCA § 3305, as amended by Public Law 32-052, riders under 18 and drivers who have not been licensed to operate a motorcycle for at least three years must wear qualifying safety helmets. The effect of any equipment issue on a particular claim depends on the evidence, injuries, and applicable law; do not assume it decides fault or recovery by itself.
Common Causes of Guam Motorcycle Accidents
Motorcycle crashes can involve turns at intersections, visibility concerns, surface conditions, debris, speed, or other driver behavior. After any crash, preserve the facts that can be checked: photographs of the roadway and vehicles, witness information, the crash-report number, medical records, and policy information. The cause of a particular crash requires evidence, not assumptions.
What to Do at the Scene
Call GPD immediately and request a crash report. Do not remove your helmet at the scene unless medically necessary — let paramedics assess you. Photograph everything: road conditions, the other vehicle's position, skid marks, your motorcycle damage, and any visible injuries. Get witness names and contact information. Do not apologize or admit fault. Seek emergency medical care immediately — motorcycle injuries often involve internal bleeding, spinal injuries, and road rash infections that worsen without treatment.
Dealing with Insurance After a Guam Motorcycle Accident
Guam’s mandatory-insurance chapter requires owners of vehicles that must be registered in Guam to maintain the chapter’s required insurance, and it sets minimum property-damage and third-party bodily-injury limits. What coverage is available after a specific crash depends on the driver, vehicle, policy terms, and facts. Review the declarations pages and any coverage notices before assuming that UM/UIM or another benefit applies. For many injury actions, 7 GCA § 11306(a) provides a two-year period, but a different rule or procedure may apply to the facts of a particular case.

Frequently Asked Questions
Does Guam require motorcycle helmets?
Guam’s current limited helmet rule is in 16 GCA § 3305, as amended by Public Law 32-052. It requires qualifying helmets for riders under 18 and drivers who have not been licensed to operate a motorcycle for at least three years. The specific facts can matter, so do not rely on a general guide to decide how a rule applies to you.
Can I recover damages if I was partly at fault for the motorcycle accident?
Fault can affect a claim, but its effect depends on the governing law, the evidence, and the parties involved. Preserve the crash report, photographs, witness information, and medical records, and seek individual legal advice before assuming an outcome.
What if the driver who hit me has no insurance?
Guam’s mandatory-insurance law addresses insurance required for vehicles that must be registered in Guam. Whether you have a particular UM, UIM, rental, medical-payment, or other benefit depends on the actual policy and its terms. Review the declarations pages and coverage notices, and get individual advice if the coverage is unclear.
