To become a certified ME, a ME must complete the necessary training and pass the certification test required by FMCSA. In order to take the FMCSA certification exam, the ME must first register through the National Registry website and receive a unique identification number. The ME will then provide ME’s unique identification number to the testing organization selected from the list of approved testing organizations on the National Registry website.

Beginning May 21, 2014, CMV drivers in interstate commerce must use certified MEs listed on the National Registry to obtain a medical certificate. Medical certificates issued prior to this date are valid until the expiration date.
