CDL Instruction Permit

Four Red, Parked Semi Trucks      

Before applying for a Colorado commercial instruction permit, you must hold a valid Colorado Driver's License. The commercial instruction permit is required before the CDL driving skills test may be administered. When both written and road tests are completed a CDL can be issued.


To receive the Commercial Driver's License (CDL) Instruction Permit you must:


  • Show acceptable identification and proof of lawful presence in the US
  • Show something with your name and your address (vehicle registration, checkbook, bill)
  • Be at least 18 years of age
  • Show proof of your Social Security Number
  • Show your current DOT medical examination (not more than 24 months old)
  • Pass the required CDL knowledge tests  (CDL Study Manual)
  • Pay the $14.00 fee and be issued an instruction permit


If you pass the required written test(s) and are issued an instruction permit, you can take the CDL driving skills test. There are three types of general skills that will be tested:

  • Pre-trip Inspection
  • Basic Vehicle Control
  • On-Road Driving


You must take these tests in the type of vehicle for which you wish to be licensed.
