Legal Requirements for Helmet Use in Colorado
For Riders Under 18
Riders and passengers under 18 years must wear DOT-approved helmets while the motorcycle is in motion. This requirement is strictly enforced to protect younger riders who may have less experience on the road. According to Colorado Revised Statutes § 42-4-1502, a person under 18 who violates this requirement commits a class A traffic infraction, which can result in fines and potentially affect driving records.
For Riders 18 and Older
Helmet use is not mandatory for riders and passengers 18 years and older in Colorado. However, safety experts and medical professionals strongly recommend wearing a helmet regardless of legal requirements. Adult riders have the freedom to choose, but this choice comes with significant safety implications.
DOT-Approved Helmet Specifications
DOT Standards
All helmets used by under-18 riders must meet the standards established by the U.S. Department of Transportation. These standards ensure adequate protection in case of an accident by testing the helmet’s ability to absorb impact and protect the brain. DOT-approved helmets have undergone rigorous testing to verify their protective capabilities.
Key Features
Approved helmets must have impact-resistant structure and secure retention systems like chin straps. They must also display proper DOT labeling that indicates compliance with federal safety standards. When purchasing a helmet, always look for the DOT sticker on the back, which confirms the helmet meets these critical safety requirements.
Eye Protection Requirements
Universal Requirement
All motorcycle operators and passengers, regardless of age, must use adequate eye protection in Colorado. According to the Colorado Department of Transportation, this includes safety glasses, face shields, or protective goggles that shield the eyes from debris, insects, and adverse weather conditions. This requirement applies even when wearing a full-face helmet if it lacks a proper face shield, and importantly, windshields alone are not considered sufficient eye protection under Colorado law.
Importance of Eye Protection
Proper eye protection safeguards against elements that can impair vision and compromise riding safety. Even a small object hitting the eye at highway speeds can cause serious injury or temporary blindness that may lead to an accident. Quality eye protection is an essential safety tool for every ride on Colorado roads.

Benefits of Wearing a Helmet, Even When Not Required
Injury Reduction
Helmet use significantly decreases the risk of severe head and brain injuries in accidents. Studies show that helmets absorb much of the impact energy that would otherwise transfer directly to the skull and brain. Even at low speeds, head injuries without helmet protection can be life-altering or fatal.
Relevant Statistics
According to the CDC, helmets are approximately 37% effective in preventing fatal injuries for riders and 41% for passengers. These statistics demonstrate the life-saving potential of helmet use, regardless of legal requirements. Medical costs for traumatic brain injuries can also be substantially reduced when helmets are worn.
Legal Implications of Not Wearing a Helmet
For Riders Under 18
Failure to comply with mandatory helmet laws for minors can result in traffic violations and fines. Parents or guardians may also face liability issues if they knowingly allow minors to ride without proper helmet protection. These violations can affect driving records and potentially lead to increased insurance premiums.
For Riders 18 and Older
Although not mandatory, not wearing a helmet could influence insurance claims or litigation following an accident. In personal injury cases, contributory negligence arguments might arise if you sustain head injuries while riding without a helmet. This could potentially affect compensation amounts in settlement negotiations or court judgments.
Colorado Motorcycle Safety Statistics and Initiatives
Recent Safety Data
According to the Colorado Department of Transportation (CODOT), motorcycle safety remains a critical concern in the state:
- In 2022, 149 motorcyclists were killed on Colorado roads, representing 20% of the state’s total traffic fatalities, but only 3% of the state’s vehicle registrations
- In 2023, there were 136 motorcyclists killed on Colorado roadways
- Of the 149 motorcycle fatalities in 2022, 75 involved riders not wearing helmets
- Data from the National Highway Traffic Safety Administration (NHTSA) shows that speed and alcohol are large contributing factors in motorcycle crashes
CDOT Safety Recommendations
CDOT encourages all motorcyclists to take these safety measures:
- Always wear protective gear and a DOT-compliant helmet. To find a helmet that’s right for you, visit the NHTSA Motorcycle Helmet webpage
- Get trained by finding a class on the Colorado State Patrol’s Motorcycle Operator Safety Training (MOST) webpage
- Get endorsed by your local DMV. Visit the Colorado DMV Motorcycle Endorsement webpage for more information
- Always obey speed limits and other rules of the road
Lane Filtering Law (2024)
Colorado recently passed a new law allowing motorcycles to pass between vehicles stopped on the roadway and traveling the same direction as the rider. Lane filtering is not the same as lane splitting and allows motorcyclists to safely navigate through stopped traffic. This law takes effect on August 7, 2024. For more details, visit the Colorado Lane Filtering Information and Resources Page.
Safety Tips for Drivers Sharing the Road with Motorcyclists
CDOT emphasizes that road safety is a shared responsibility. Drivers should:
- Always check blind spots for motorcycles
- Always look twice when pulling onto a roadway
- Avoid distractions, such as using phones while driving
- Never follow motorcycles too closely

Tips for Safe Motorcycle Riding in Colorado
Protective Equipment
Beyond helmets and eye protection, riders should consider jackets, gloves, and boots designed specifically for motorcyclists. Proper riding gear provides protection against road rash, impacts, and weather conditions. Investing in quality gear is investing in your safety and can make the difference between minor and severe injuries.
Training and Education
Participate in safety courses to improve riding skills and knowledge. Organizations like the Motorcycle Safety Foundation offer courses for riders of all levels. These programs teach defensive riding techniques, hazard awareness, and proper handling skills that can prevent accidents before they happen.
Vehicle Maintenance
Perform regular inspections to ensure your motorcycle functions properly. Check tires, brakes, lights, and fluid levels before every ride. Mechanical failures at highway speeds can lead to serious accidents, making preventative maintenance a crucial aspect of motorcycle safety.
(FAQ) Frequently Asked Questions
Are passengers required to wear helmets in Colorado?
Yes, if they are under 18 years old. For passengers 18 and older, helmet use is not mandatory but highly recommended for safety.
Are there any exceptions to the helmet requirement for riders under 18?
Yes, Colorado law provides a specific exception for minors operating or riding in certain autocycles. According to Colorado Revised Statutes § 42-4-1502(4.5)(c), individuals under 18 are not required to wear a helmet while driving or riding in an autocycle if the vehicle meets all the following criteria:
- Has three wheels
- Is designed for a maximum speed of 25 miles per hour or less
- Is equipped with a windshield
- Has seat belts
It’s important to note that this exception applies exclusively to autocycles that fulfill all the above conditions. For all other motorcycles and autocycles not meeting these specifications, helmet use remains mandatory for riders and passengers under the age of 18.
What qualifies as adequate eye protection?
Safety glasses, face shields integrated into helmets, or protective goggles designed for motorcyclists. Regular sunglasses or eyeglasses may not provide sufficient protection against wind, debris, or impacts. According to Colorado law (C.R.S. § 42-4-1502), windshields alone are not considered adequate eye protection. The Colorado Division of Motor Vehicles requires eye protection that is specifically designed for motorcycle use.
Can I be fined for not wearing a helmet if I'm over 18?
No, you cannot be cited specifically for not wearing a helmet if you’re 18 or older. However, you can be fined for not using proper eye protection, which is required for all riders regardless of age.
Where can I find the official Colorado motorcycle helmet laws?

Do motorcycle helmet laws in Colorado ever change?
Like all traffic laws, motorcycle helmet regulations can be subject to legislative changes. It’s important to stay informed about current laws through official government sources rather than relying on outdated information.
