About the Colorado CDL exam
The Colorado CDL exam is administered by the Colorado Division of Motor Vehicles. Like every state, Colorado adopts the federal standards as a baseline and adds state-specific requirements, fees, and procedures.
- Exam / licence fee: approximately $17.60.
- Skills testing: Colorado DMV locations.
- Colorado is among the states that strictly enforces the altitude adjustment requirement — CDL holders must account for reduced braking efficiency in mountain driving.
