How We Help Injured Cyclists

Bicycle accident cases involve unique challenges that differ from typical car accident claims: bias against cyclists, disputes over who had the right-of-way, and insurers who try to minimize payouts for “just a bike accident.” Our attorneys investigate the crash, gather physical and digital evidence, identify every liable party and applicable insurance policy, handle all communication with insurance companies, and pursue maximum compensation for your medical bills, lost income, and pain and suffering — through negotiation or, when necessary, litigation.

Bicycle Accident Claims at a Glance

• Filing deadline: Generally 3 years for injury claims arising from a motor vehicle collision (C.R.S. § 13-80-101), or 2 years for many other negligence claims (C.R.S. § 13-80-102). Claims against a government entity involve much shorter notice deadlines. Confirm your exact deadline with an attorney as soon as possible.
• Fault standard: Colorado follows a modified comparative negligence rule — you may still recover damages if you are found less than 50% at fault, though your award is reduced by your percentage of fault.
• Insurance: Colorado drivers must carry minimum liability insurance (C.R.S. § 10-4-620); a cyclist’s own auto policy may also provide uninsured/underinsured motorist or MedPay coverage.
• Fees: We represent injured cyclists on a contingency-fee basis — you pay no attorney fee unless we recover compensation for you.

Types of Bicycle Accident Cases We Handle

We represent cyclists injured in a wide range of crashes, including:

• Car- or truck-versus-bicycle collisions at intersections, driveways, and mid-block
• “Dooring” collisions, where a parked car’s door opens into a cyclist’s path
• Right-hook and left-hook turning collisions
• Rear-end collisions caused by unsafe passing or distracted driving
• Hit-and-run bicycle accidents
• Crashes caused by dangerous road or bike-lane conditions (potholes, debris, poor signage, defective design) — which may involve a claim against a government entity
• Bicycle accidents involving defective bikes, e-bikes, or e-bike batteries (product liability)
• Bicycle-on-bicycle and bicycle-on-pedestrian collisions

Common Causes of Bicycle Accidents

Most bicycle accidents we see involve one or more of the following: distracted or inattentive driving, a driver failing to yield the right-of-way, unsafe or too-close passing in violation of Colorado’s three-foot law, dooring by a parked motorist, left- or right-turning drivers who fail to check for cyclists, drivers under the influence of alcohol or drugs, speeding, and hazardous road or bike-lane conditions such as potholes, uneven pavement, or debris.

Who Can Be Held Liable

Liability depends on the facts of each crash, but potentially responsible parties can include:

• Negligent drivers who violate traffic laws, drive distracted, or fail to yield to cyclists
• Employers, if the at-fault driver was working at the time of the crash
• Government entities responsible for dangerous road, bike-lane, or intersection design or maintenance — these claims involve special, much shorter notice deadlines and immunity rules under Colorado’s governmental immunity statutes, so time is critical (citation should be confirmed with an attorney before relying on any specific deadline)
• Manufacturers or retailers, if a defective bicycle, e-bike, or e-bike battery contributed to the crash or injuries
• Property owners, if an unsafe condition on private property contributed to the crash

Preserving Evidence After a Crash

Evidence in bicycle accident cases can disappear quickly — traffic camera footage may be overwritten, vehicle damage may be repaired, and witness memories fade. Where possible, it helps to preserve: photographs of the scene, your bicycle, your injuries, and the other vehicle; the police report and responding officer’s information; contact and insurance information for the driver and any witnesses; medical records documenting your treatment; and any available surveillance, dashcam, or helmet-camera footage. Our firm moves quickly to send preservation letters and gather this evidence before it is lost.

Colorado Bicycle Laws

Colorado law gives cyclists specific rights and responsibilities on the road. Key statutes include:

• C.R.S. § 42-4-1412 (Operation of bicycles and other human-powered vehicles): Cyclists generally have the same rights and duties as drivers of motor vehicles. The statute addresses riding single file where required, prohibitions on clinging to other vehicles, keeping at least one hand on the handlebars, using hand signals, riding no more than two abreast without impeding traffic, and rules for riding on sidewalks and paths. Violations are generally a class 2 misdemeanor traffic offense.
• C.R.S. § 42-4-1003 (Overtaking on the left): A driver overtaking a cyclist must leave a safe distance, generally at least three feet, between their vehicle and the cyclist.
• C.R.S. § 42-4-221 (Bicycle equipment requirements): Bicycles ridden at night or in low visibility must have a front light visible from a distance (roughly 500 feet) and a rear red reflector or light visible from a distance (roughly 600 feet), and must be equipped with brakes capable of stopping the bicycle within a specified distance.
• C.R.S. § 42-4-204 (When lighted lamps are required): Lights are required from sunset to sunrise and any time visibility is substantially reduced.
• C.R.S. § 42-4-1402.5 (Vulnerable road users): Colorado law provides enhanced penalties for drivers who injure a “vulnerable road user,” a category that includes cyclists.

Insurance Coverage for Cyclists

Colorado requires drivers to carry minimum automobile liability insurance under C.R.S. § 10-4-620. A cyclist injured by a motorist may be able to recover from that driver’s liability coverage. In addition, if the at-fault driver is uninsured, underinsured, or unidentified (a hit-and-run), the cyclist’s own auto insurance policy may provide uninsured motorist (UM), underinsured motorist (UIM), or Medical Payments (MedPay) coverage — even though the cyclist was not driving a car at the time of the crash. Because policy language varies, we recommend having an attorney review all potentially applicable policies.

Damages Available

Depending on the facts of your case, compensation may include past and future medical expenses, lost wages and diminished future earning capacity, property damage to your bicycle and gear, pain and suffering, disfigurement and scarring, loss of enjoyment of life, and — in fatal crashes — wrongful death damages for surviving family members. Colorado law caps certain noneconomic damages in personal injury cases (C.R.S. § 13-21-102.5), with the cap adjusted periodically for inflation; punitive damages may also be available in cases involving especially reckless conduct (C.R.S. § 13-21-102).

What Affects Your Case Value

Every bicycle accident case is different, but value is generally influenced by the severity and permanence of your injuries, how clear liability is, whether you share any percentage of fault, the insurance policy limits available, your documented lost income, the quality and consistency of your medical treatment, and the strength of the evidence and witness testimony supporting your version of events.

Common Bicycle Accident Injuries

Cyclists have little protection in a collision with a motor vehicle, and injuries are often serious. We frequently see traumatic brain injuries and concussions, road rash and severe lacerations, broken bones and fractures, spinal cord injuries, shoulder and joint injuries, dental and facial injuries, and, in the most severe cases, permanent disability or death.

What To Do After a Bicycle Accident

• Seek medical attention right away, even if you feel fine — some injuries aren’t immediately obvious
• Call the police and request a written accident report
• Photograph the scene, your bicycle, your injuries, and the vehicle involved
• Get the driver’s contact and insurance information, and identify any witnesses
• Avoid giving a recorded statement to any insurance company before speaking with an attorney
• Keep records of all medical treatment and related expenses
• Contact a Colorado bicycle accident attorney as soon as possible

Our Process

We start with a free, no-obligation consultation to evaluate your case. From there, we investigate the crash, gather and preserve evidence, identify all liable parties and insurance coverage, coordinate with your medical providers, and handle all communication and negotiation with insurance companies on your behalf. If a fair settlement can’t be reached, we’re prepared to file suit and litigate your case through trial.

Attorney Fees

We represent injured cyclists on a contingency-fee basis. That means there is no upfront cost to hire us, and we only get paid a fee if we successfully recover compensation for you.
