Colorado does not require adults to wear a motorcycle helmet. Anyone under 18 who drives or rides on a motorcycle, autocycle or low-power scooter must wear one while the vehicle is moving. That is the short answer, and it comes straight from C.R.S. § 42-4-1502. The longer answer has a few wrinkles that matter: what counts as an approved helmet, what the penalty is, how eye protection fits in, what the rules look like for e-bikes, and why “legal to ride without one” does not always mean “no consequences after a crash.”
We practice in Colorado Springs and see what happens on the road and in the aftermath. This guide explains the law as it stands in 2026, in plain terms. It is general information, not advice for your specific situation.

Colorado’s Motorcycle Helmet Law
Colorado’s helmet law is found in C.R.S. § 42-4-1502.
The statute requires anyone under 18 who drives or rides as a passenger on a motorcycle, autocycle, or low-power scooter on a roadway to wear a protective helmet.
The Colorado General Assembly’s summary of the helmet law confirms that the requirement applies to passengers too.
That means a 17-year-old riding on the back of a motorcycle driven by a 40-year-old still has to wear a helmet, even though the adult driver does not.
The statute also requires the helmet to be properly secured with a chin strap while the motorcycle is moving.
The Colorado State Patrol’s motorcycle law page provides a useful overview of Colorado’s motorcycle rules.
What Kind of Helmet Is Required?
For riders under 18, qualified helmets must meet certain criteria.
Colorado requires a helmet designed for motorcycle use that meets or exceeds Federal Motor Vehicle Safety Standard No. 218, the federal DOT motorcycle helmet standard.
The helmet must include appropriate lining, padding, and a chin strap.
In practical terms, look for a legitimate DOT-compliant motorcycle helmet rather than a novelty helmet that simply looks like one.
Are There Any Exceptions?
There is a narrow exception involving certain autocycles.
A person riding in an autocycle does not have to wear the otherwise required helmet if the vehicle meets the requirements stated in the statute.
If you own or drive an autocycle, it is worth reading the full text of C.R.S. § 42-4-1502 because the exception depends on how the vehicle is constructed.
For a normal two-wheel motorcycle, the exception does not apply.
What Is the Penalty for Riding Without a Required Helmet?
A violation of C.R.S. § 42-4-1502 is a Class A traffic infraction.
That is a traffic violation, not a criminal offense. It does not carry jail time.
If a minor receives a motorcycle citation, however, I would still look at exactly what was charged rather than assuming it is insignificant. Motorcycle stops can involve other allegations involving licensing, equipment, careless driving, speeding, or other traffic offenses.
You can read more in our guide to Colorado traffic fines and points.
We also explain how long a traffic ticket stays on your record.
Eye Protection Is Required Even for Adults
This is probably the part of Colorado motorcycle law that surprises people most.
An adult can legally ride without a helmet.
The adult cannot simply ride with no eye protection.
Colorado law generally requires the driver and passengers of a motorcycle on a public highway to wear qualifying goggles or eyeglasses, or use qualifying eye protection incorporated into a helmet.
The Colorado State Patrol’s motorcycle law page specifically notes that a windshield does not count as adequate eye protection for an ordinary motorcycle.
So an adult rider can legally skip the helmet but still receive a citation for riding without the required eye protection.
Violation of the eye-protection requirement is also a Class A traffic infraction.

Colorado Leaves the Helmet Decision to Adult Riders
Colorado has made a fairly clear policy choice.
Adults are allowed to decide whether to wear a motorcycle helmet.
That does not mean helmets are ineffective.
According to the Colorado Department of Transportation, motorcycle crashes continue to account for a significant number of traffic fatalities in Colorado.
CDOT reported that 165 motorcyclists were killed on Colorado roads in 2024. The number dropped to 148 in 2025.
CDOT has also reported that nearly half of the motorcyclists killed in Colorado during a recent five-year period were not wearing helmets.
Those statistics do not tell us whether a helmet would have prevented a particular death. They do explain why state safety agencies continue to encourage riders to use them.
The Colorado State Patrol’s protective gear guidance recommends a DOT-compliant helmet along with riding boots, gloves, and protective clothing.
So the legal answer and the safety answer are two different questions.
The legal answer is simple. If you are 18 or older, Colorado does not require you to wear a motorcycle helmet.
What Happens If You Are Injured While Riding Without a Helmet?
This is where the law gets interesting.
Suppose another driver runs a red light and hits a motorcyclist. The rider suffers a serious head injury and was not wearing a helmet.
Can the driver’s insurance company argue that the motorcyclist caused part of his own injuries by choosing not to wear one?
For an adult rider, Colorado case law says no.
The Colorado Supreme Court addressed this issue in Dare v. Sobule.
The Court held that evidence of a motorcyclist’s failure to wear a helmet could not be used to establish comparative negligence or reduce damages.
Colorado does not impose a legal duty on an adult motorcyclist to wear a helmet. The Court declined to create one through civil negligence law when the legislature had chosen not to require helmets.
Colorado appellate courts have continued to recognize that rule.
That is an important distinction.
Colorado does use comparative negligence in personal injury cases. If your own negligent conduct contributed to an accident, your compensation may be reduced, and you can be barred from recovery if your responsibility reaches the statutory threshold.
But an adult’s lawful decision not to wear a motorcycle helmet cannot simply be turned into comparative negligence.
An insurer may still investigate every other part of a motorcycle accident, including speed, lane position, impairment, visibility, braking, and the actions of both drivers. Helmet nonuse, however, is treated differently under Colorado law.
If another driver’s careless driving caused the crash, our article on careless driving causing injury explains some of the issues that can arise.
What Should You Do After a Motorcycle Accident?
Motorcycle crashes can produce serious injuries even when the rider initially feels capable of walking away.
Get medical care.
Call law enforcement and make sure the accident is documented.
Photograph the vehicles, roadway, debris, traffic signals, skid marks, and any visible injuries if you can safely do so.
Keep your helmet, clothing, damaged motorcycle equipment, and other physical evidence.
Get contact information from witnesses.
Be careful about giving a detailed recorded statement to the other driver’s insurance company before you understand your injuries and your rights.
We have a separate guide explaining what to do after a motorcycle accident in Colorado Springs.
If the driver who hit you does not have insurance, read our guide on what to do if you are hit by an uninsured driver in Colorado.
What About E-Bikes?
Colorado treats electric bicycles differently from motorcycles.
There is no statewide helmet requirement for adults riding ordinary bicycles or Class 1 and Class 2 e-bikes.
The Colorado Department of Transportation’s e-bike safety page explains Colorado’s three e-bike classifications.
Class 1 e-bikes provide assistance only while the rider pedals, with assistance ending at 20 mph.
Class 2 e-bikes can provide motor assistance without pedaling, with assistance ending at 20 mph.
Class 3 e-bikes provide assistance while the rider pedals, with assistance ending at 28 mph.
Class 3 bikes have additional restrictions.
A person under 16 generally cannot operate a Class 3 e-bike, although a person under 16 may ride as a passenger.
Anyone under 18 riding a Class 3 e-bike must wear a helmet.
Local governments also have authority over where certain e-bikes can be ridden. Trail, park, and local regulations may therefore be more restrictive than the general statewide rules.
CDOT’s information for bicyclists also covers other bicycle requirements, including lighting and equipment rules.
