Minimum auto insurance limits required in Colorado

Colorado drivers are required to carry liability insurance, which helps pay for others' injuries or property damage if you're responsible for a crash.

The minimum coverage levels you must buy in Colorado are:

$25,000 bodily injury liability per person.
$50,000 bodily injury liability per accident.
$15,000 property damage liability per accident.

Liability car insurance covers the cost of any damage, injuries or deaths you cause in a car accident, up to your policy’s predefined limits.

But it’s often best to buy more than the bare minimum to avoid being left vulnerable to lawsuits or major accident bills. You also want to consider other coverage types such as collision and comprehensive, which pay for damage to or theft of your own car.

Alternative car insurance in Colorado

Colorado drivers who can’t get coverage on the open market because of past crashes or other factors can apply for coverage through the Colorado Motor Vehicle Plan.

Methodology

For our “good driver” profile, NerdWallet averaged insurance estimates for single male and female drivers with good credit and no tickets or violations. The analysis included 5-10 of the largest insurance companies in each state; smaller insurers were also included when rates were available. Liberty Mutual and its subsidiaries were excluded from our analysis as rates were not available.

For full coverage policies, we used the following coverage limits:

$100,000 bodily injury liability per person.
$300,000 bodily injury liability per accident.
$50,000 property damage liability per accident.
$100,000 uninsured motorist coverage per person.
$300,000 uninsured motorist coverage per accident.
Collision coverage with a $1,000 deductible.
Comprehensive coverage with a $1,000 deductible.

In states where required, minimum additional coverages were added. Some policies include additional coverages at the insurer’s discretion.

We used a 2020 Toyota Camry L for all drivers and assumed 12,000 annual miles driven.

We analyzed rates for drivers 20 to 70 years old in ten-year increments. For the average cost of full and minimum coverage in each state, we looked at 35-year-old drivers.

We used the same assumptions for all other driver profiles, with the following exceptions:

For drivers with minimum coverage, we adjusted the numbers above to reflect the minimum required coverage by law in the state.
We changed the credit tier from “good” to “poor” as reported to the insurer to see rates for drivers with poor credit.
For drivers with one at-fault crash, we added a single at-fault crash that happened six months ago, resulting in $10,000 in property damage and no bodily injury claim.
For drivers with a DUI, we added a single drunken driving violation that happened six months ago.

We looked at 35-year-old drivers to find the cheapest company overall, the cheapest company for minimum coverage and the cheapest company for drivers with poor credit in states where credit history is used to price rates. We looked at 20-year-old drivers to find the cheapest company for young drivers.
