CDL Disqualifications

Wyoming law (W.S. 31-7-305) states commercial driver license (CDL) holders may be disqualified from driving a commercial motor vehicle (CMV), have their license canceled or be prohibited from obtaining a CDL if they are convicted of 2 or more serious moving violations in a 3-year period.  The first disqualification is for 60 days.  A third or subsequent conviction causes a 120 day disqualification.  
The following are considered serious violations:
  • Speeding 15 mph or more 
  • Following too closely
  • Not obtaining a CDL
  • Driving without a CDL in possession
  • Improper or no endorsements
  • Reckless driving
  • Erratic or improper lane change
  • Use of cell phone OR texting while driving a CMV
A driver will have their license cancelled and will be disqualified from driving a CMV or from obtaining a CDL if convicted of any of the following:
  • Driving under the influence
  • Drives or operates a CMV with a blood alcohol of .04% or greater
  • Leaving the scene of an accident
  • Driving under suspension in a CMV
  • Motor vehicle used in a felony
  • Negligent operation of a CMV causing a fatality
A first conviction results in a driver being disqualified for one (1) year.  If hazardous materials were involved, it is a three (3) year disqualification.  A second or subsequent conviction causes a lifetime disqualification.

Railroad Crossing Disqualifications

CDL drivers who have a passenger or hazardous material endorsement are required to stop at all railroad crossings.  You will be disqualified if convicted of one of the following:
  • Failure to stop at a railroad crossing,
  • Failure to obey a traffic control device,
  • Failure to negotiate a railroad crossing because of insufficient under carriage clearance, and 
  • Failure to stop before reaching the crossing if the tracks are not clear.
A first conviction will result in a 60 day disqualification and a 120 day disqualification for a second or subsequent conviction.
Once a CDL driver has been disqualified they are required to be retested. This includes both the driving skills test and any written tests needed for re-licensing.
Note: Effective starting January 1, 2014, a CDL driver who has been disqualified will be required to obtain a Commercial Learners Permit (CLP), prior to re-licensing.
