This blog provides a detailed overview of the regulations, requirements, costs, and benefits of this permit.
What is a Colorado Single Trip Oversize/Overweight Permit?
A Colorado Single Trip Oversize/Overweight Permit authorizes a commercial motor vehicle to transport a single non-divisible load that exceeds legal size and/or weight limits. Unlike annual permits, which cover multiple moves within a year, a single trip permit is valid for one specific journey between designated points.
These permits are designed for carriers hauling equipment or freight that cannot be reduced in size or weight, such as construction machinery, industrial components, bridge beams, wind turbine blades, or large agricultural equipment.
Colorado Legal Dimensions and Weight Limits
Before applying for a permit, it’s important to know the legal limits in Colorado. Loads that exceed these limits require a single trip oversize or overweight permit:
Width: 8 feet 6 inches
Height: 14 feet 6 inches
Length:
45 feet (single unit vehicle)
65 feet (combination of vehicles)
75 feet (auto transporters with front/rear overhang allowances)Weight:
20,000 pounds per single axle
36,000 pounds per tandem axle
54,000 pounds per tridem axle
80,000 pounds gross weight (federal bridge formula applies)

Route Planning and Bridge Analysis
One of the most critical elements of a single trip overweight permit is route planning. CDOT uses the Colorado Bridge Analysis System (COBRAS) to ensure overweight loads do not damage infrastructure. The permit application process requires:

- Exact route information
At Compare Transport LLC, we assist carriers in preparing this information to avoid delays and ensure compliance
