Ports of Entry

The State of Colorado created its first port of entry in 1927, primarily for tax collection purposes.  Since that time, the role of the ports of entry has expanded to include enforcement of truck size and weight restrictions, safety inspections, collection of fees and fines, and checks of required permits, vehicle registrations, and operator licenses.  The Colorado State Patrol (CSP) operates ten fixed ports in the state:  Cortez, Dumont, Fort Collins, Fort Morgan, Lamar, Limon, Loma, Monument, Platteville, and Trinidad.  The fixed ports are strategically located in positions throughout the state that receive high volumes of truck traffic.

The following vehicles are required to clear a port of entry:

  • all commercial vehicles in excess of 16,000 pounds empty weight;
  • all commercial vehicles in excess of 26,000 pounds gross vehicle weight rating;
  • all vehicles displaying apportioned or gross vehicle weight license plates; and
  • any vehicle carrying an amount of hazardous materials requiring a placard.

Further information on ports of entry, permits, fees, and related topics can be found on the CSP's website.
