Understanding Colorado Oversize Permit Regulations
Colorado has strict regulations governing trucking permits. Any load exceeding standard dimensions must obtain a Colorado Oversize Permit before transit. Here are the key operating guidelines:
Permit Validity: A Colorado Oversize Permit is valid for five days.
Operating Time: Standard travel from sunrise to sunset. However, loads up to 12' wide can operate at night if they have proper lighting and flagging.
Restricted Routes: Some roads require additional caution:
The Eisenhower Tunnel on I-70 restricts maximum height to 13'-11”.
Oversized loads exceeding 11’ wide must call for clearance before passing through the tunnel.
Loads entering Denver city streets require a separate city permit, which takes 2-3 days for processing.
Types of Oversize and Overweight Permits in Colorado
At A Permits, we handle a variety of trucking permits to streamline your operations:
- Colorado Oversize Permits
These permits allow truckers to transport wide, tall, or long loads legally on designated Colorado highways.
- Colorado Overweight Permits
When load exceeds weight regulations, truckers must secure an overweight permit to legally transit without penalties.
- Colorado Overhang Permits
For loads that extend beyond the trailer's rear or front, an overhang permit is required to maintain roadway safety.
- Colorado Single Trip Permits
Ideal for one-time oversized transport, these permits allow safe passage for unique transports.
- Colorado Annual Permits
For frequent oversized load transport, an annual permit allows multiple trips without reapplication.
