The Federal Motor Carrier Safety Administration has extended its temporary waiver allowing commercial drivers and motor carriers to use paper medical examiner certificates for up to 60 days after issuance, up from the previous 15-day allowance, as state licensing agencies continue transitioning to electronic medical certification systems. The modified waiver addresses ongoing implementation challenges with the National Registry II electronic transmission requirements that took effect June 23, with only 38 states and the District of Columbia currently compliant while 12 states including California, Florida, and New York have yet to implement the new system.
