"Many States are experiencing backlogs or reduced hours of operation in their State Driver Licensing Agencies (SDLAs). As a result, many CDL and CLP holders may be unable to renew their CDLs and CLPs or provide medical certificates to their SDLA. In addition, due to limited operations or backlogs, drivers may be unable to obtain appointments for physical examinations with medical examiners to comply with the Federal Motor Carrier Safety Regulations (FMCSRs)."
