Effective July 1, 2011, Wyoming CDL holders operating in certain types of commerce are required to submit to WYDOT – Driver Services a current DOT Medical Examiner's Certificate to obtain a "certified" status as part of their driving record. CDL holders are required to have this status, and those who do not provide and keep a current medical certificate on file with us will become "not-certified" and their driver license is subject to cancellation.
As of January 20, 2012, Commercial Driver License holders are required to certify to a single type of commercial operation and must provide information to their licensing state regarding the type of commercial motor vehicle operation they drive in or expect to drive in with their CDL. When a driver applies for a CDL or renews a CDL or applies for a higher class of CDL or applies for a new endorsement on a CDL or transfers a CDL from another state, the holder is required to certify to this on their driver license application form.
If you still need to certify with Driver Services, you may pick up a Commercial Driver License Certification Application from your local driver exam station or download one from the Forms page.
