Motorcycle Accidents In Denver

When a car hits a motorcycle, the rider almost always loses. You’re exposed, your bike is lighter, and drivers often say the same thing after a crash: “I just didn’t see the motorcycle.” This page explains how Colorado law treats motorcycle accidents, what to expect from the insurance company, and the steps you can take right now to protect your claim. If you were injured on a bike anywhere in the Denver metro—along I-25, I-70, Colfax, Speer, Colorado Boulevard, or surface streets in Aurora, Arvada, Lakewood, or nearby—you can talk with Harding & Associates for free.

Why Motorcycle Cases Are Different

Motorcycle crashes are not just “car accidents without doors.”

• Severe injuries are common. With no frame or airbags, riders face direct impact, ejection, and sliding injuries.
• Visibility is a problem. Bikes are smaller in mirrors and blind spots; left-turn and lane-change collisions are frequent.
• Bias exists. Adjusters and jurors may assume a rider was speeding, lane-splitting, or “taking risks,” even when the driver simply didn’t look.

Our job is to replace bias with evidence—showing exactly how and why the crash happened and what it has done to your life.

Common Causes Of Motorcycle Crashes In Denver

We routinely see the same dangerous patterns:

• Left-turn collisions – a driver turns left across a rider’s lane at an intersection or driveway.
• Unsafe lane changes – the driver fails to check blind spots or mirrors, especially on multi-lane highways.
• Rear-end crashes – stop-and-go traffic on I-25/I-70 and downtown streets leaves riders vulnerable to distracted drivers.
• Distracted driving – texting, scrolling, or using navigation instead of watching for motorcycles.
• Failure to yield when merging, entering from side streets, or pulling out of parking lots.
• Dangerous road conditions – loose gravel, potholes, or slick surfaces that affect bikes much more than cars.

In many cases, the rider was doing everything reasonably possible—the other driver simply failed to look or give space.

Colorado Motorcycle Laws That Can Affect Your Claim

You don’t need to memorize the Colorado Revised Statutes, but a few key rules matter in motorcycle cases.

Helmet Rules

Under C.R.S. § 42-4-1502, Colorado requires a DOT-approved helmet for all riders and passengers under 18 (and for certain permit holders). Riders and passengers 18 and older are not legally required to wear a helmet, although safety experts—and Colorado’s own motorcycle safety materials—strongly recommend one. Not wearing a helmet as an adult does not automatically bar your claim, but insurers may argue it contributed to particular head injuries. We address that with medical experts and Colorado law.

Eye Protection Is Mandatory

Colorado law also requires all motorcycle operators and passengers to wear some form of eye protection—goggles, glasses, or a face shield made of safety glass or plastic—under the state’s minimum safety standards for motorcycles. A windshield alone does not count as eye protection, as confirmed by multiple summaries of Colorado motorcycle laws. This can become an issue if the defense tries to blame the crash on impaired vision—for example, an object striking your eyes because protective gear wasn’t used.

Lane Filtering vs. Lane Splitting

Starting August 7, 2024, Colorado’s lane filtering law (SB24-079) allows riders to filter between stopped vehicles in limited circumstances, as described in the CDOT “lane filtering” update and the Colorado State Patrol’s lane filtering guidance. In plain English:

• Lane filtering (legal, pilot program through 2027):
  • Traffic in the lanes you’re passing must be stopped.
  • You may pass between lanes of traffic going the same direction.
  • You may not exceed 15 mph while filtering.
  • You may not use the shoulder to pass.
• Lane splitting (still illegal):
  • Riding between lanes of moving traffic, or using the shoulder to pass, remains against Colorado law.

Insurance companies sometimes lump everything together as “lane splitting.” We clarify the difference and show when you were actually riding within the law.

Fault & Colorado’s Comparative Negligence Rule

Colorado follows modified comparative negligence under C.R.S. § 13-21-111. HLAW’s own article on understanding fault in Colorado car accidents explains the framework in everyday terms. In plain terms:

• You can recover compensation as long as your negligence is not as great as the negligence of the person(s) you’re suing (a “50% bar” rule).
• Any award is reduced by your percentage of fault.

Example: If your damages are valued at $300,000 and you’re found 20% at fault, your recovery could be reduced to $240,000. If you were found 50% or more at fault, you may recover nothing. Insurance companies know this and will try to shift blame onto the rider (speeding, lane position, “weaving,” no helmet). Our job is to push that percentage down with facts, not assumptions.

Injuries And Damages In Motorcycle Accidents

Because riders are so exposed, injuries are often serious and long-lasting:

• Traumatic brain injuries (TBI) and concussions
• Spinal cord damage and paralysis
• Complex fractures and joint injuries
• Road rash, burns, and degloving injuries
• Amputations and crush injuries
• Scarring, disfigurement, and chronic pain
• PTSD, anxiety, and other emotional harm

We build a damages picture that can include:

• Past and future medical expenses (surgery, rehab, medication, mobility aids)
• Lost wages and reduced earning capacity
• Pain, suffering, emotional distress, and physical impairment
• Scarring/disfigurement and loss of enjoyment of life
• Out-of-pocket costs and mileage to appointments
• Damage to your motorcycle, gear, and personal items

Evidence That Strengthens A Motorcycle Case

The more clearly we can reconstruct what happened, the harder it is for the insurer to deny or minimize your claim. Key evidence often includes:

• Scene photos and video – vehicle positions, skid marks, debris, sight lines, traffic signals, road defects, weather, and lighting.
• Motorcycle inspection – impact points, bent components, and damage patterns can show speed, direction, and angle of impact.
• Gear and clothing – helmet, jacket, gloves, boots, and torn clothing help document the violence of the crash.
• Witness statements – what bystanders saw and heard, including any admissions by the driver.
• Police report & 911/CAD logs – officer observations and early statements.
• Digital data – dashcams, surrounding surveillance cameras, vehicle event data recorders, and sometimes phone records if distraction is suspected.
• Medical records – diagnosis, treatment timeline, and opinions on future care.

We move quickly to preserve bikes and gear, send preservation letters for digital evidence, and capture witness memories before they fade.

Insurance Coverage & Compensation Sources

In a motorcycle case, there may be multiple potential sources of recovery:

• At-fault driver’s liability insurance (BI) – the primary starting point.
• Your own UM/UIM coverage – crucial if the driver is uninsured, underinsured, or flees the scene; see our page on Uninsured & Underinsured Motorist (UM/UIM) Claims for more detail.  You should opt for at least $250,000 of UN/UIM coverage.
• MedPay – may help with immediate medical bills, regardless of fault.
• Health insurance – coordinates with any injury settlement.
• Employer policies – if either driver was in the course of employment.
• In limited circumstances, product defect or roadway design/government liability.

We create a coverage map so no layer is overlooked.

Colorado Deadlines You Can’t Miss

Most motorcycle crashes are treated as motor-vehicle accidents, so the general rule is:

• Three years from when the claim accrues to file a lawsuit for bodily injury or property damage “arising out of the use or operation of a motor vehicle” under C.R.S. § 13-80-101(1)(n).

Other injury claims may have a two-year deadline, and cases involving a public entity (for example, a city vehicle or dangerous road condition) usually require a formal written notice within 182 days under Colorado’s Governmental Immunity Act. Translation: you should talk to a lawyer as soon as possible. Waiting can mean lost evidence and missed deadlines.

What To Do Right Now (Checklist)

If you’re able, these steps can help protect both your health and your claim:

1. Get medical care immediately. Even “minor” pain can mask serious injuries.
2. Call the police and get a report or incident number.
3. Take photos and video of the scene, vehicles, your bike, and your injuries.
4. Gather names and contact info for witnesses and nearby businesses with cameras.
5. Preserve your motorcycle and gear in their post-crash condition—don’t rush repairs.
6. Do not admit fault or speculate about speed, distance, or visibility.
7. Avoid recorded statements to the other driver’s insurer.
8. Locate your insurance policy (for UM/UIM and MedPay information).
9. Call Harding & Associates at 303-762-9500 or contact us online for a free case review.

FAQs: Motorcycle Accidents In Denver

Do I have a case if I wasn’t wearing a helmet? If you’re 18 or older, Colorado law does not require a helmet, although safety experts strongly recommend one. The helmet requirements for riders and passengers under 18 are set out in C.R.S. § 42-4-1502. Not wearing a helmet doesn’t automatically destroy your claim, but the defense may argue it contributed to certain head injuries; we counter that with medical testimony and a full picture of fault. Is lane splitting legal in Colorado? What about lane filtering? Traditional lane splitting between moving cars is still illegal. Colorado’s 2024 lane filtering law allows motorcycles to pass between stopped vehicles traveling the same direction, at 15 mph or less, when lanes are wide enough and the shoulder is not used, as outlined in CDOT’s update on the new lane filtering law and the Colorado State Patrol’s lane filtering announcement. If the insurer tries to blame you for “lane splitting,” we examine whether you were actually lawfully filtering under this new rule. What if I was partly at fault for the crash? Under Colorado’s modified comparative negligence rule, you can generally recover if your fault is less than 50%, but your damages are reduced by your percentage of blame; at 50% or more, recovery is barred. The statute is found at C.R.S. § 13-21-111, and our blog on understanding fault in Colorado car accidents breaks down how that works in practice. We focus on minimizing any fault assigned to you and highlighting the driver’s choices. How long do I have to file a motorcycle accident lawsuit? Most motorcycle injury claims fall under the three-year motor-vehicle statute of limitations, found in C.R.S. § 13-80-101(n), but there are exceptions, and government-related cases have much shorter notice requirements under the Colorado Governmental Immunity Act. Because deadlines are complex, the safest move is to get legal advice as soon as possible. What if the driver who hit me was uninsured or fled the scene? You may still have options through your Uninsured/Underinsured Motorist (UM/UIM) coverage. We review your policy, handle communications with your insurer, and pursue a UM/UIM claim when appropriate, as discussed in more detail on our UM/UIM claims page and our article on hit-and-run accidents in Colorado.
