Frequently Asked Questions
Why do we need IRP?
Under IRP, you can register in a single base state such as Colorado or a Canadian province for operations in two or more jurisdictions.
Why is it important to state exact miles?
You are paying for the privilege to use highway and infrastructures in the United States and Canada. The more accurate that you are when stating your miles in each jurisdiction makes your payment for usage more accurate to each jurisdiction.
What is the grace period on a renewal?
The grace period offered by Colorado allows the carrier the entire month following their expiration date to renew their registration. For example, if your expiration date is July 31, 2006, you have the month of August, 2006 to renew and pick up or receive by mail your permanent credentials. If a registration is not renewed, the registration expires on the expiration date with no grace period.
What kind of information should be kept on file for future reference or audits?
You should keep mileage records for the current registration and the prior three years on file. You may obtain these records from various sources. It is up to the carrier as to how they document miles traveled.
Can I use IRP if I want to register in Colorado only as a commercial vehicle?
No, you would need to go to your county office.
Moving your company to Colorado?
You will need to call 303-205-5608 for further requirements.
I occasionally travel out of Colorado do I need IRP?
Since occasionally traveling you might want to check with that state you are traveling to regarding their trip permits
