What Commercial Auto Insurance Requirements Apply in Colorado?

Colorado requires an owner who operates or knowingly permits a motor vehicle on public highways to keep a complying policy, with a current self-insurance certificate as the statutory alternative. The basic liability limits are $25,000 for one person, $50,000 for all people in an accident, and $15,000 for property damage. A person with more than 25 vehicles registered in that person’s name may apply for a certificate, but must obtain the commissioner’s approval.

What Is Commercial Auto Insurance?

Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled. Read the national Commercial auto guide.

What Should You Watch for With Commercial Auto Insurance in Colorado?

Vehicle Count Alone Does Not Make You Self-Insured
A person with more than 25 vehicles registered in that person’s name may apply, but Colorado’s commissioner must issue a current certificate after assessing ability to pay the required benefits and judgments. Confirm the certificate names the applicant and is issued before relying on self-insurance. ^1,³
Check Which Entity Holds The Registrations
Colorado counts vehicles registered in the applying person’s name, and the commissioner may cancel a certificate after notice and hearing for reasonable grounds. Failure to pay required benefits or a final judgment within 30 days is an express cancellation ground; make sure the certificate holder tracks those obligations and its status. ¹
Keep The Complying Policy Limit With Each Highway Unit
Colorado’s required minimum applies to the owner’s complying policy for a motor vehicle operated or knowingly permitted on public highways, unless that owner has a current certificate of self-insurance. Ask the broker to confirm the scheduled policy limits and certificate status for each unit. ^1,²

Which Commercial Auto Providers Have Colorado License Records?

These providers publish a national listing for Commercial auto; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Colorado. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁶

When Colorado is the insured’s home state, its surplus-lines tax is 3% of taxable premium.
