Colorado does not require adult motorcycle riders to wear a helmet. That surprises a lot of people, including riders who have lived here their whole lives. But the helmet question matters a lot more after a crash than it does on any given ride, and the way it plays into your injury claim is where most riders get caught off guard.
I ride and race in Colorado. I also represent riders who get hit by cars that pulled out in front of them, drifted into their lane, or blew through a stop sign. So I want to walk through what the law actually says, what it doesn't say, and where the real risk sits if you're ever in a wreck.
Under C.R.S. § 42-4-1502, only riders and passengers under 18 are required to wear a DOT-approved helmet, secured with a chin strap, while riding a motorcycle, autocycle, or low-power scooter. There's a narrow exception for minors in certain enclosed autocycles that meet specific safety criteria, but for standard motorcycles, if you're under 18, the helmet requirement is not optional.
If you're 18 or older, the choice is yours. Colorado had a universal helmet law on the books from the 1960s through 1977, when it was repealed and later challenged in court in a case called Love v. Bell. Since then, adult riders in this state have had the legal right to ride without a helmet.
One requirement that applies to every rider, regardless of age, is eye protection. A visor, goggles, or safety glasses with impact-resistant lenses are mandatory any time you're on the road. A windshield on the bike doesn't count.
Here's what actually matters if you're ever in a crash. Not wearing a helmet doesn't cause an accident, and Colorado law doesn't pretend otherwise. But under Colorado's modified comparative fault statute, C.R.S. § 13-21-111, an insurance company can still argue that riding without a helmet made your injuries worse than they would have been. If a jury or adjuster agrees, your percentage of fault goes up, and your recovery goes down by that same percentage. If your assigned fault reaches 50%, you can be barred from recovering anything at all.
This is the insurance playbook. They can't say you caused the wreck. So instead they argue you made your own injuries worse, and try to shift a chunk of the value of your case onto your shoulders.
That argument only works if it goes unanswered. Whether a helmet would have changed the outcome of a specific head or facial injury is a medical and biomechanical question, not something an adjuster gets to assume. That's exactly the kind of argument that needs to be built out and countered with real evidence, not conceded at intake.
My fee is 29% pre-litigation and 33% if we sue, compared to the 33-35% and 40-45% most Colorado firms charge. Every client gets my direct cell phone number, not a paralegal pool.
Talk to Dylan About Your CaseNo. Colorado law only requires a DOT-approved helmet for riders and passengers under 18. Adult riders can legally choose not to wear one.
It can be used as an argument, not as an automatic bar. Under Colorado's modified comparative fault rule, an insurance company may argue your injuries were made worse by riding without a helmet, which can reduce your recovery. That argument has to be proven, not assumed, and it can be challenged with the right medical and biomechanical evidence.
Yes. Colorado requires eye protection, such as a visor, goggles, or safety glasses, for every rider and passenger regardless of age. A windshield alone does not satisfy this requirement.
Yes. The under-18 helmet requirement applies equally to passengers, not just the operator of the motorcycle.
