Uninsured Motorist Coverage — Colorado

What Uninsured Motorist Coverage Actually Protects
Uninsured motorist coverage pays for injuries and vehicle damage when a driver with no insurance hits one of your cars. In Colorado, 19.7% of motorists drive without insurance — nearly one in five drivers on the road. When you're managing two or more vehicles on one policy, that exposure multiplies: every car your household drives faces the same odds of being hit by an uninsured driver, and Colorado doesn't require you to carry UM coverage at all.
The coverage splits into two parts. Uninsured motorist bodily injury (UMBI) pays medical bills, lost wages, and injury costs for you and your passengers when an uninsured driver causes a crash. Underinsured motorist coverage (UIMBI) kicks in when the at-fault driver carries liability insurance but their limits are too low to cover your injuries. Uninsured motorist property damage (UMPD) pays to repair your vehicle when an uninsured driver damages it — but Colorado law doesn't require carriers to offer UMPD, and many don't.

Why Colorado Doesn't Require UM Coverage
Colorado is one of eight states that doesn't mandate uninsured motorist coverage. The state requires only liability insurance: $25,000 per person for bodily injury, $50,000 per accident, and $15,000 for property damage. Those minimums protect other people when you cause a crash. They do nothing for you when someone else hits your car and carries no insurance.
That structural gap matters more when you're insuring multiple vehicles. A household with three cars makes three times as many trips as a single-car household. More road time means more exposure to uninsured drivers. The decision to add UM coverage or skip it applies to every vehicle on your policy — you can't selectively protect one car and leave the others exposed under most carrier structures.
Carriers must offer UMBI when you buy a policy in Colorado, but you can decline it in writing. UMPD is optional for carriers to offer at all, and many don't include it in their Colorado products. That means even if you want property damage protection from uninsured drivers, your carrier may not sell it.
Colorado carriers must offer UMBI, but you can decline it. UMPD is optional for carriers to offer, and many don't — leaving your vehicles exposed to uninsured property damage even if you want coverage.
UMPD and Collision: Two Different Paths
Uninsured motorist property damage coverage and collision coverage both pay to repair your vehicle after a crash, but they work differently and cost differently. UMPD pays only when an uninsured driver damages your car and you can identify the driver. Hit-and-run crashes where the driver flees usually don't qualify unless your carrier's UMPD policy includes hit-and-run coverage, which is rare in Colorado. Collision coverage pays regardless of fault and covers hit-and-run damage, single-car crashes, and collisions with objects.
UMPD typically carries a lower deductible than collision — sometimes no deductible at all — but it's harder to use. You must prove the other driver was uninsured and at fault. Collision coverage requires no proof of fault; you file a claim, pay your deductible, and your carrier repairs the car. For households managing multiple vehicles, collision coverage is the more reliable path. UMPD is a supplement, not a replacement.
Many Colorado carriers don't offer UMPD at all. If your carrier does, compare the premium difference between adding UMPD to every vehicle on your policy versus raising your collision coverage limits. The collision path often costs less and covers more scenarios.

Colorado Minimum Bodily Injury Limits
Colorado requires $25,000 per person and $50,000 per accident in liability coverage. When an at-fault driver carries only the minimum and your injuries exceed that, UIMBI covers the gap up to your policy's limit.

How UM Limits Work Across Multiple Vehicles
When you add uninsured motorist coverage to a multi-vehicle policy, the limit you select applies per person, per accident, across all vehicles. You don't buy separate UMBI limits for each vehicle — the coverage is shared across the household.
That shared structure creates a decision point for multi-car households. A single serious crash involving one of your vehicles can exhaust your UMBI limit if multiple people are injured. If you're insuring three or four vehicles and multiple household members drive regularly, consider whether your UMBI limit is high enough to cover a worst-case scenario. Raising your UMBI limit costs less than adding collision coverage to another vehicle, and it protects everyone in every car.
Compare Carriers That Write UM in Colorado
Not every carrier offers the same UM options in Colorado. Some offer UMBI only; others offer both UMBI and UMPD. A few carriers let you stack UM coverage across multiple vehicles on the same policy, multiplying your limits when more than one car is involved in a crash. Stacking isn't common in Colorado, but when it's available it significantly increases your protection for households with multiple vehicles.
When you're comparing carriers for a multi-vehicle policy, ask three questions: Does the carrier offer UMPD in Colorado? Does the carrier allow UM stacking? What is the premium difference between adding UM to every vehicle versus skipping it entirely? The answers vary by carrier. Colorado's carrier roster includes 27 companies writing auto insurance in the state, and their UM products differ significantly. Compare quotes with and without UM coverage to see the cost difference for your household's specific vehicle count and driver mix.
What UMBI Pays For Across Your Household
UMBI pays medical bills, rehabilitation costs, lost wages, and pain-and-suffering damages for anyone injured in your vehicle when an uninsured driver is at fault. If your teenager is driving one of your household's cars and gets hit by a driver with no insurance, UMBI covers your teen and any passengers. The same applies to your spouse driving a different vehicle on the same policy. The coverage limit you select applies per person, per accident, across all vehicles on the policy.
Underinsured motorist coverage works the same way but triggers when the at-fault driver carries liability insurance that's too low to cover your injuries. Colorado's minimum bodily injury limit is $25,000 per person. If you're seriously injured and the at-fault driver carries only the state minimum, UIMBI pays the difference between their limit and your actual costs, up to your UIMBI limit. For households with multiple vehicles and multiple drivers, that gap protection matters — a single serious crash can exceed $25,000 in medical costs quickly.
