Here’s the fact that matters most. Colorado does not require adult riders to wear helmets. The statute is C.R.S. § 42-4-1502, and it only covers riders under 18. If you’re an adult who chose to ride without a helmet, you didn’t break any law.
That’s not a technicality. That’s the law.
Insurance adjusters will still try to use it against you, and we see this play out constantly in cases across the Denver metro. A rider gets hit by a car making a left turn at Arapahoe Road and Yosemite Street, the driver ran the light or failed to yield, clear fault, and the insurance company’s first move is to point at the rider’s head and say, “Well, you weren’t wearing a helmet.” They want you to feel like you did something wrong. You didn’t. Not wearing a helmet is a legal choice for any adult in Colorado, and that driver’s insurance company still owes you for what their insured caused.
The other driver caused the crash. That doesn’t change because of what was or wasn’t on your head.
Why the Law Matters for Your Motorcycle Accident Case
Colorado’s modified comparative negligence rule under C.R.S. § 13-21-111 says you can recover damages as long as you’re less than 50% at fault. At 50% or more, you recover nothing. Insurance companies work hard to push that number up in motorcycle cases, no helmet, dark clothing, speed, lane position. Anything to shift blame onto the rider.
But not wearing a helmet isn’t negligence. You followed the law. A defense attorney can still argue that a helmet would have reduced your head injuries, and a jury may hear that argument. The question isn’t whether you broke a rule. It’s whether the lack of a helmet actually made your specific injuries worse, and those are two very different things.
The insurance company just hopes you don’t know the difference.
How This Plays Out in Real Cases
Picture a rider heading south on I-25 near the DTC, just past the Orchard Road exit, a stretch where traffic bunches up fast and lane changes happen without much warning. A distracted driver drifts over. The rider goes down hard. Broken collarbone, road rash, a concussion. No helmet. The insurance company comes in low, arguing the concussion wouldn’t have happened with head protection.
But the broken bones? The road rash? The lost wages? None of that changes with a helmet. And the concussion itself needs to be evaluated by medical experts who can say whether a helmet would have actually prevented it in this specific crash, not crashes in general, not crash simulations, but this one.
Adjusters lump everything together on purpose. They want you to accept less for all your injuries because of one injury that might have been different. That’s not how Colorado law works, and it’s not something we let stand.

We’ve secured a $45 million motorcycle accident settlement and a $42 million verdict in motorcycle collision cases. Insurance companies know which firms actually take these cases to trial, and that knowledge changes every conversation from the first phone call forward. If you’re wondering how helmet use might affect your claim, our motorcycle accident lawyers can walk you through exactly where you stand.
Colorado law gave you the right to ride without a helmet. No insurance company gets to punish you for using it.
How Colorado’s Comparative Negligence Law Affects Your Injury Claim
This is where insurance companies do their real damage. And it’s where not wearing a helmet can actually cost you money, even though it was a legal choice.
Colorado follows modified comparative negligence under C.R.S. § 13-21-111. Plain version: if you’re partly at fault for your injuries, your compensation gets reduced by your percentage of fault. If a jury puts you at 50% or more, you get nothing.
So the adjuster’s job is to push your fault number as high as possible.
How the Helmet Argument Works Against You
Say another driver ran a red light near the I-25 and Arapahoe Road interchange in Greenwood Village and hit you on your motorcycle. Their fault, clearly. But you weren’t wearing a helmet and you suffered a head injury. The insurance company won’t argue you caused the crash, they can’t. They’ll argue you made your injuries worse by not protecting your head. Colorado courts allow that argument, and defense teams use it regularly.
The defense hires a biomechanical expert who testifies that a helmet would have reduced your head trauma by some percentage. Then they ask the jury to assign you, say, 30% of the fault for your injury severity. On a $1 million case, that’s $300,000 gone. The crash wasn’t your fault. But the injuries? Now they’re partly yours, according to the defense.
Insurance companies count on you not knowing this is coming.
The 50% Cliff
The real danger is getting pushed to that 50% line. Say you were going slightly over the speed limit on South Yosemite Street, had no helmet, and a car turned left into your path. The other driver is mostly at fault, but the defense stacks arguments. Speeding. No helmet. Maybe dark clothing at dusk. Each one adds a few percentage points. If those points stack to 50%, your case is worth zero under Colorado law.
That’s not a hypothetical. We’ve seen this play out.
We handle motorcycle accident cases where comparative negligence is the central fight, not liability. The crash is obviously someone else’s fault. The battle is over how much fault gets assigned to the rider for injury severity. A strong motorcycle accident lawyer knows how to keep that number low, by challenging the defense’s medical experts and building the record to show the injuries would have happened regardless of helmet use.
What This Means for Your Case Strategy
Your attorney needs to do two things early. Get your own biomechanical and medical experts lined up to counter the helmet argument. Then build a record that separates the cause of the crash from the cause of the injuries, because those are two separate questions, and the defense wants the jury to blur them together.
If you’ve been in a motorcycle accident in the Greenwood Village area and weren’t wearing a helmet, the clock matters. Colorado gives you three years to file under C.R.S. § 13-80-101, but evidence disappears fast. Surveillance footage from the intersection gets overwritten. Witnesses forget what they saw. The sooner your case gets built, the harder it is for the insurance company to inflate your fault percentage with arguments that go unchallenged.

Insurance Companies Use Helmet Non-Use to Reduce Early Settlement Offers 
Here’s what actually happens. You file a motorcycle accident claim after a crash on I-25 near the Orchard Road interchange in Greenwood Village. The other driver ran a red light. Clear liability. But you weren’t wearing a helmet. Within weeks, the insurance adjuster sends a low offer, and buried in the reasoning is one line about your “failure to mitigate injuries.”
That’s the playbook. Riders across Colorado run into this same tactic again and again.
Colorado law under C.R.S. § 42-4-1502 makes helmets optional for riders 18 and older. You broke no law. But the adjuster treats your legal choice like a confession of recklessness, folding it into the first offer and hoping you’ll accept before you realize what they’re doing. They’re counting on you not knowing this.
How Adjusters Build the Argument
The tactic follows a pattern. The adjuster pulls your medical records and finds a head injury, facial laceration, or concussion. Then they argue a helmet would have prevented or reduced that specific injury. They attach a dollar figure to the “preventable” portion of your treatment and subtract it from the offer.
Sometimes they go further. They’ll hire a biomechanical expert early in the process to write a report saying your head injuries would have been 40% or 60% less severe with a helmet. That report becomes the foundation for slashing your offer before you’ve even finished treating.
“Insurance companies know which firms actually take cases to trial, and that affects how your case is handled. A lot of the high-volume firms don’t actually try cases. In fact, many times they end up calling firms like ours to litigate and take their cases to trial.”, Jason Jordan, Founding Partner
What does this look like in real numbers? Say your medical bills total $200,000 after a crash along Arapahoe Road. Lost wages add another $80,000. The adjuster might offer $120,000 total, claiming that helmet non-use contributed to 50% of your head-related treatment costs. They present it like math. It’s not math. It’s a negotiation tactic dressed up as science.
Why Early Offers Are Almost Always Too Low
The first offer in any motorcycle accident case is a test. The insurance company wants to see if you’ll bite. When they can point to no helmet, they feel more confident pushing a low number, they assume you’ll feel defensive about your choice and settle fast.
Colorado’s modified comparative negligence rule under C.R.S. § 13-21-111 means the other driver’s fault is what matters most. If that driver was 90% at fault, you still recover 90% of your damages. Not wearing a helmet doesn’t make you 50% responsible for a crash someone else caused. The crash and the injury severity are two separate questions, and most people don’t realize that until it’s too late.
They accept the early offer thinking the helmet issue kills their case. It doesn’t.
A motorcycle accident lawyer who handles these cases regularly knows how to challenge the adjuster’s biomechanical reports, bring in competing medical evidence, and force the insurer to separate crash causation from injury severity. We’ve recovered a $45 million motorcycle accident settlement and a $42 million motorcycle collision verdict right here in Colorado. Those results come from knowing exactly how to take apart the arguments insurance companies build around rider behavior.
If you’ve already received a low offer that mentions your helmet choice, don’t respond yet. Talk to a motorcycle accident lawyer who understands how Colorado insurers use this tactic, and knows how to push back.
Frequently Asked Questions
Does not wearing a helmet make me at fault for my motorcycle accident in Colorado?
No. Colorado law under C.R.S. § 42-4-1502 only requires helmets for riders under 18. As an adult, you made a legal choice. Not wearing a helmet doesn’t mean you caused the crash. The insurance company may argue it made your injuries worse, that’s a different argument, and one that requires medical and biomechanical evidence to support. Your attorney’s job is to challenge that evidence directly.
Can the insurance company reduce my settlement because I wasn’t wearing a helmet?
They’ll try. Under Colorado’s modified comparative negligence rule (C.R.S. § 13-21-111), insurers can argue that your choice not to wear a helmet increased the severity of your head injuries, and that some percentage of fault for those injuries belongs to you. If they succeed, your recovery gets reduced by that percentage. A motorcycle accident lawyer who regularly handles these cases knows how to fight that argument with competing expert testimony.
What if I’m assigned 50% or more fault for not wearing a helmet?
Under C.R.S. § 13-21-111, reaching 50% fault means you recover nothing. That’s the cliff insurance companies try to push riders toward when they can stack multiple arguments, no helmet, speed, dark clothing, lane position. Keeping that number below 50% is one of the most important jobs your attorney has in a motorcycle accident case.
How long do I have to file a motorcycle accident claim in Colorado?
Three years from the date of the crash under C.R.S. § 13-80-101. But waiting that long is a real problem. Surveillance footage gets overwritten. Witnesses move or forget details. Physical evidence disappears. The sooner your case gets built, the better your position when the insurance company tries to inflate your fault percentage.
What if a government vehicle or road condition caused my motorcycle accident?
Claims against government entities, the City of Greenwood Village, CDOT, or Arapahoe County, follow different rules under the Colorado Governmental Immunity Act (C.R.S. § 24-10-109). You have 182 days from the date of the incident to file a written notice of claim. Miss that window and you likely lose the right to sue entirely. If a government entity is involved in your crash, contact a motorcycle accident lawyer immediately.
