The Federal Motor Carrier Safety Administration (FMCSA) regulates the activities of truckers and trucking firms, requiring drivers to maintain logbooks and electronic records in all states, including Texas. Since December 18, 2017, all trucking companies have been required to comply with the Electronic Logging Device (ELD) rule. Truck drivers must have electronic logging devices installed in their vehicles. If they were previously using automatic onboard recording devices, they had to have been updated to an ELD by December 16, 2019.
