CDL Drivers

Commercial drivers face more to lose than any other driver when facing a DUI charge in Colorado.  Either an administrative or criminal conviction will result in the CDL being revoked for one (1) year.  It does not matter that you were driving a personal vehicle.  If you have a valid Commercial Driver’s License and you are convicted criminally or administratively, you lose your CDL privileges for a minimum of one (1) year.

If your BAC was .170 or higher and you are convicted administratively or criminally, you will not be able to obtain a CDL until all interlock requirements are met and the ignition interlock device is no longer required as part of your driving privilege requirements. 

Thus, if you BAC is .170 or higher and you have a Commercial Driver’s License, you are looking at having that privilege revoked for a minimum of 25 months (one month no driving and two years on required interlock).

A second offense will result in a lifetime disqualification of the Commercial Driver’s License.

• The lifetime disqualification only applies if both offenses were after the holder obtained the CDL and both offenses also occurred after October 1, 2005.
