Hit by an Uninsured or Underinsured Driver: UM/UIM Coverage for Colorado Motorcycle Riders

Key Takeaways

Colorado’s minimum liability coverage is only $25,000. For a serious motorcycle injury, $25,000 disappears fast and leaves you to cover the rest.
Uninsured motorist (UM) coverage protects you when the at-fault driver has no insurance, flees the scene, or cannot be identified.
Underinsured motorist (UIM) coverage steps in when the driver has insurance but not enough.
UM/UIM comes from your own policy. It is the coverage you control, and for riders it is often the difference between a full recovery and a fraction of one.
Colorado bars insurers from cutting your UM/UIM through a setoff. You collect from the at-fault driver and from your own UM/UIM on top, up to your limit.
UM/UIM is optional, but your insurer can only leave it off your policy if you rejected it in writing. If you never signed a rejection, you may have coverage you did not know about.
A UM/UIM claim is a claim against your own insurer, and insurers do not always pay willingly. Colorado law gives you remedies if your insurer unreasonably delays or denies a valid claim.

Picture this. A driver turns left across your path on a clear afternoon. You had the right of way, the crash was not close to your fault, and now you are in an emergency room with a broken leg and a bill that is climbing by the hour. Then you find out the driver who hit you carries the Colorado minimum, $25,000 in bodily injury coverage, or no coverage at all.

This is one of the worst surprises a rider can get. You did everything right, and the person who hurt you cannot pay for the harm they caused. The good news is that there is a form of coverage built for exactly this situation, and a lot of riders either do not have it or do not know how it works. It is called uninsured and underinsured motorist coverage, usually written as UM/UIM.

If you ride in Colorado, this is the coverage worth understanding before you ever need it. Here is what it does, why it matters more for riders than for most drivers, and how a Colorado laws put more money in your pocket than people expect.

Why the State Minimum Is Not Enough for a Motorcycle Crash

Colorado requires drivers to carry at least 25/50/15 in liability coverage. That means $25,000 for bodily injury to one person, $50,000 for bodily injury per accident, and $15,000 for property damage. Plenty of drivers carry only that minimum, and some nothing at all.

For a fender bender between two cars, $25,000 might cover it. For a motorcycle crash, it usually does not come close. Riders take the full force of a collision with no metal cage and no airbags around them. A single surgery, a few days in the hospital, and some time off work can blow past $25,000 before you have even started physical therapy. When the at-fault driver’s coverage runs out, the rest of the bill does not disappear. It lands on you, unless you have a way to fill the gap.

Studies have repeatedly placed Colorado among the states with the most uninsured and underinsured drivers on the road. So the odds that the person who hits you cannot fully pay are not small. They are real, and they are higher here than in much of the country.

What UM and UIM Actually Cover

UM and UIM are usually sold together and listed on your policy as one line. They cover bodily injury, meaning the harm done to you, in two related situations.

Uninsured motorist (UM)
This applies when the at-fault driver has no insurance at all. It also applies in a hit-and-run, or when the driver who caused the crash cannot be identified or located. For riders, that last part matters. If a car drifts into your lane, runs you off the road, and never stops, UM coverage may be your only source of recovery. There are reporting and evidence requirements for these claims, so what you do right after the crash counts.

Underinsured motorist (UIM)
This applies when the at-fault driver does have insurance, but the limits are too low to cover your injuries. This is the more common scenario. The driver has the state minimum, you have damages well above it, and UIM bridges the difference up to the limit you bought.

One point worth clearing up: UM/UIM covers bodily injury, not the damage to your bike. To repair or replace the motorcycle itself, you would look to the at-fault driver’s property damage liability or to your own collision coverage.

The Colorado Rule That Works in Your Favor

Here is the part most people get wrong, and it is the part that puts real money on the table. Under Colorado law, your UM/UIM coverage cannot be reduced by a setoff. That means your own insurer is not allowed to subtract what the at-fault driver paid from your UM/UIM limit. You collect from the at-fault driver, and then you collect from your own UM/UIM on top of that, up to your limit.

An example makes this clear. Say your damages from a motorcycle crash come to $150,000. The driver who hit you carries the state minimum of $25,000, and their insurer pays it. You are still $125,000 short. If you carry $100,000 in UM/UIM, your own policy pays the gap up to its $100,000 limit. So you recover $25,000 from the at-fault driver plus $100,000 from your UM/UIM, for $125,000 total.

That example also carries a lesson. Even with $100,000 in UM/UIM, the rider in this case still came up $25,000 short of full damages. Serious motorcycle injuries get expensive, so it is worth asking your agent about higher UM/UIM limits. The added premium for more protection is usually modest compared to what a bad crash actually costs.

It Is Optional, So Check Your Policy

Colorado does not force you to buy UM/UIM, but it does require your insurer to offer it in an amount equal to your bodily injury liability limits. The only way it comes off your policy is if you rejected it in writing. That detail is worth repeating, because it cuts in your favor.

If your insurer cannot produce a written rejection signed by you, you may have UM/UIM coverage even if you thought you did not. People sometimes assume they declined it, or an agent assumes it for them, and the paperwork was never done correctly. Pull out your declarations page and look. If you are not sure what you are looking at, that is a question worth asking before you assume the worst about your options.

Colorado also allows stacking of UM/UIM coverage in certain situations, which can combine limits across more than one vehicle or policy in a household. The rules here get technical and depend on the facts, so it is the kind of thing worth having someone review rather than guessing at on your own.

Your Own Insurer Is Not Always on Your Side

A UM/UIM claim has a twist that surprises people. You are no longer dealing with the other driver’s insurance company. You are making a claim against your own. You pay them premiums, so you might expect them to step up. Sometimes they do. Sometimes they treat your claim the same way any insurer treats a payout they would rather not make. They question your injuries, dispute your treatment, and push to settle low.

Colorado law does not leave you without recourse when that happens. If an insurer unreasonably delays or denies payment of a valid claim, the law gives the policyholder remedies, which can include additional damages and attorney fees. You do not have to accept being slow-walked on a claim you paid to have.

What to Do After the Crash

A few steps protect your ability to use this coverage:

Report the crash and get medical care right away. UM claims, especially hit-and-run claims, often depend on prompt reporting and a clear record.
Document the scene. Photos, witness names and numbers, and the police report all help, particularly when the other driver is uninsured or never stopped.
Find your declarations page and confirm your UM/UIM limits. If you cannot find a written rejection, do not assume you lack coverage.
Do not give a recorded statement to any insurer, including your own, before you understand your rights. Adjusters use these to limit what they pay.
Act promptly. UM/UIM claims have their own deadlines, and your policy may require you to notify the insurer within a set time.
Have someone review all the policies that might apply, not just the one on your bike. Coverage in a household is not always limited to a single vehicle.
