## Abstract

The FMCSA announces a 120-day grace period during which Medical Examiners may use either the current or the newly revised versions of the Medical Examination Report (MER) Form and Medical Examiner's Certificate (MEC). This period is from December 22, 2015, until April 20, 2016. This action is being taken to ensure that Medical Examiners have sufficient time to become familiar with the new forms and to program electronic medical records systems.
