Colorado CDL Requirements

The Colorado Division of Motor Vehicles (DMV) issues CDLs in three classes. Class A covers combination vehicles over 26,001 lbs towing over 10,000 lbs. Class B covers single vehicles over 26,001 lbs. Class C covers hazmat or passenger vehicles. Applicants must be 18 for intrastate or 21 for interstate. Colorado requires a valid Colorado driver license, Social Security card, proof of Colorado residency, and US citizenship or lawful presence documentation. ELDT requirements apply. Colorado has approximately 45 FMCSA-registered ELDT providers, concentrated in the Denver metro, Colorado Springs, Pueblo, and Grand Junction areas. Mountain driving proficiency is informally expected but not specifically tested beyond the standard skills test.

The Colorado CDL costs $18.52 for the endorsement plus standard license fees totaling approximately $35-$50 for a 5-year license. The CLP costs $18.52. Knowledge tests are $9.52 per attempt, administered at DMV offices statewide. Skills tests are available through the state and authorized third-party testers ($200-$400). Colorado DMV offices in Denver, Aurora, Colorado Springs, Fort Collins, and Pueblo handle the highest CDL volumes. Knowledge tests are available in English and Spanish. Wait times for skills testing at DMV locations can be 2-4 weeks, making third-party testers a faster alternative. The state allows three skills test attempts before requiring additional training and a 30-day wait.

Colorado offers all standard CDL endorsements. The Hazmat (H) endorsement requires a TSA background check ($86.50). Tank (N) is valuable for the state's petroleum and chemical industries. Double/Triple (T) is useful for I-25 and I-76 corridor LTL operations. The most in-demand endorsements along the Front Range are H and T. The ski resort industry creates demand for Passenger (P) endorsed drivers during winter months. Endorsement knowledge tests cost $9.52 each. Colorado's growing cannabis industry has created niche demand for CDL drivers with specific cargo handling experience, though federal marijuana prohibition creates legal complexities for CDL holders under DOT drug testing requirements.

Colorado offers diverse CDL training options. Emily Griffith Technical College (Denver) and Pueblo Community College provide CDL programs at $2,500-$5,000. Private schools including Advanced Career Institute (Grand Junction), National Western Truck Driving School (Denver), and CDL School Colorado Springs charge $4,000-$8,000. The Colorado Department of Labor and Employment offers WIOA training assistance. Some programs include mountain driving modules covering chain installation, grade braking techniques, and winter weather operations — essential skills for Colorado trucking that basic CDL curricula may not cover. Werner Enterprises and Schneider have Denver-area terminals offering company-sponsored training. Veterans can use GI Bill at approved schools.
