To obtain your Colorado Commercial
Drivers License (CDL), you must first pass the Colorado CDL Tests that apply to the type of commercial trucks or buses that you will
be driving. The CO CDL Tests include a General Knowledge written examination
that everyone must pass, regardless of their particular Class of License,
ie: Class A, Class B, or Class C. There are also (7) seven additional CO CDL
Tests covering endorsements including Combination Vehicles, Doubles
and Triples, Air Brakes, Passenger Vehicles, School Bus, Hazardous Materials
and Tank Vehicles. You only have to pass the CO CDL Tests that apply to your
vehicle/load requirements. You will also be given a three-part Driving
Skills Test, including a Vehicle Pre-trip Inspection, Vehicle Control
and Road Test in a representative-type vehicle.
The Congress of the United States enacted The Commercial Motor Vehicle Safety Act of 1986 (CMVSA/86) administered by the FMCSA which requires that all of the individual states conduct uniform testing and licensing standards for all commercial drivers. It also established uniform standards for qualification, suspensions, and revocation. It requires that no commercial vehicle operator may possess more than one license. That license MUST BE ISSUED FROM THE DRIVER'S STATE OF LEGAL RESIDENCE. Therefore, if you are a resident of Colorado, you MUST obtain a Colorado CDL. Our Course covers the specific Colorado CDL procedures.
You can download a free Colorado CDL Handbook that will show you the type of material that the CDL tests are based on. The complete Colorado CDL Course package will prepare you for your Colorado CDL tests complete with a Quick Review (bulleted items that you really must know) and Practice Test Questions with CORRECT Answers covering the whole pool of actual test questions asked on the Colorado CDL tests.
