Colorado Truck Permits for trip, fuel, oversize & overweight

A truck without Colorado IRP or IFTA runs on the 72-hour laden weight trip permit and a special fuel tax permit from the State Patrol's Ports of Entry. Oversize, overweight and hazmat permits come from CDOT. Both are ordered through COOPR. Tell us the truck, load and route, and our permit desk files every permit Colorado needs.

Colorado and its neighbors

How Colorado permits differ from the states around it

A route from Kansas, Nebraska, Wyoming, Utah, Oklahoma, New Mexico or Arizona meets mountain rules at the Colorado line.

  1. A foot more height

    Colorado's legal height is 14 ft 6 in. Oklahoma's is 13 ft 6 in, so a load that needs a height permit there can run legal-height in Colorado, until the Eisenhower Tunnel.

  2. Escort certificates from three neighbors

    Among its neighbors, Colorado accepts escort certificates only from Utah, Oklahoma and Arizona. Escorts certified in Kansas, Nebraska, Wyoming or New Mexico need a recognized certificate.

  3. Heavier off the interstate, less than Oklahoma

    Colorado allows 85,000 lbs gross off the interstate. Oklahoma allows 90,000 lbs on its state highways.

  4. Two agencies, one system

    CDOT issues oversize permits and the State Patrol issues trip and fuel permits, but both come through COOPR. Oklahoma splits them between ODOT and its Corporation Commission.

FAQ

Colorado permit questions

What permits does a truck need to run in Colorado?

A truck with Colorado on its IRP cab card and an IFTA license needs no trip or fuel permit. Without them it needs a 72-hour laden weight permit and a special fuel tax permit. A load over the legal size or weight also needs a CDOT permit.

What is a Colorado 72-hour laden weight permit?

A trip permit for trucks over 16,000 lbs empty, up to 80,000 lbs, without Colorado IRP registration. It is valid for 72 hours and as many trips as needed in that time.

Who needs a Colorado special fuel tax permit?

Trucks with three or more axles or over 26,000 lbs without an IFTA license. The permit records the entry point, destination and miles in Colorado.

Do I have to stop at a Colorado port of entry?

Yes, if a port is within five road miles of your route, and always when an oversize permit routes you through one. Colorado has ten State Patrol ports of entry.

Can Route One GO handle Colorado and the other states on my route?

Yes. Send the load and route once, and our permit desk files with CDOT, the State Patrol and every other state you cross. Requests are taken 24/7.
