Riding a motorcycle offers a sense of freedom and excitement that few other modes of transportation can match. But with that freedom comes responsibility—especially for new riders. Understanding the laws that govern motorcycle use in Colorado is essential not only for staying legal but also for staying safe. From licensing requirements to helmet rules and lane usage, these laws are designed to protect both riders and others on the road.
Here are seven key road laws every new biker in Colorado should know before hitting the pavement.
Before you can legally operate a motorcycle in Colorado, you must obtain a motorcycle endorsement on your driver’s license. This involves passing a written test and a skills test, or alternatively, completing a Motorcycle Safety Foundation (MSF) course, which can waive the skills test requirement. Riding without the proper endorsement can result in fines and complications if you're involved in an accident. Insurance companies may even deny claims if you’re not properly licensed, making this one of the most important steps for any new rider.
Colorado has a relatively relaxed helmet law compared to other states. Riders and passengers under 18 are required to wear DOT-approved helmets, while those 18 and older are not legally obligated to do so. However, all riders—regardless of age—must wear eye protection unless the motorcycle is equipped with a windscreen. Acceptable forms of eye protection include helmet visors, goggles, or safety glasses made of shatter-resistant material. Even though helmets are optional for adults, they are strongly recommended for safety.
Lane splitting, the practice of riding between lanes of traffic, is illegal in Colorado. However, lane filtering—passing stopped traffic at low speeds—was legalized in 2024 under specific conditions. Riders must not exceed 15 mph while filtering through stopped traffic going in the same direction. Additionally, motorcycles are allowed to share a lane with one other motorcycle, but not with cars. Understanding these distinctions is crucial for avoiding fines and staying safe in traffic.
If you plan to carry a passenger, your motorcycle must be equipped with a designated passenger seat and footrests. Passengers under 18 must wear a helmet and eye protection, just like younger riders[3]. They must also sit behind the driver or in a sidecar—never in front. Ensuring your bike is properly outfitted for passengers is not only a legal requirement but also a key safety measure.
Colorado law mandates that motorcycles be equipped with specific safety features. These include a headlight that remains on while the engine is running, a taillight, a rear reflector, a horn, at least one mirror, and working brakes on at least one wheel[3]. Tires must be in good condition and meet manufacturer specifications. Additionally, motorcycles must have a securely mounted rear license plate. These requirements help ensure visibility and control, especially in emergency situations.
All motorcyclists in Colorado are required to carry liability insurance. The minimum coverage includes $25,000 for bodily injury or death of one person, $50,000 for two or more people, and $15,000 for property damage. While this meets legal standards, it may not be sufficient in the event of a serious accident. Riders are encouraged to consider additional coverage options such as uninsured motorist protection and medical payments coverage. These policies can provide critical financial support if you're injured or your bike is damaged.
Even the most cautious riders can find themselves in an accident. When that happens, understanding your rights and having proper legal representation is essential. Motorcycle accidents often involve complex liability issues, especially when commercial vehicles are involved. Working with experienced motorcycle accident lawyers in Fort Collins can help you navigate insurance claims, gather evidence, and pursue fair compensation. These professionals understand the unique challenges motorcyclists face and can be a vital resource during recovery.
Motorcycling in Colorado can be a thrilling and rewarding experience, but it comes with a set of responsibilities that every new rider must take seriously. From licensing and safety gear to lane usage and insurance, these laws are designed to protect you and others on the road. By understanding and following these seven key regulations, you’ll not only stay compliant— you’ll also ride with greater confidence and peace of mind. Whether you're cruising through the mountains or commuting through town, knowledge is your best defense.
