The Electronic Logging Device (ELD) Rule applies to most motor carriers and drivers who are required to keep records of duty status (RODS). This includes commercial buses as well as trucks. It applies to drivers domiciled in Canada and Mexico, unless they qualify for an exception to the rule.
An ELD is technology that automatically records a driver’s driving time and other hours-of-service (HOS) data. This allows easier, more accurate HOS recordkeeping. An ELD monitors a vehicle’s engine to capture data on whether the engine is running, whether the vehicle is moving, miles driven, and duration of engine operation (engine hours). During the first phase of the ELD rule, law enforcement can review a driver’s hours of service by viewing the ELD’s display screen or from an ELD printout.
