Under the federal hours of service Regulations, a motor carrier must fit each commercial vehicle it operates with an electronic logging device (ELD) that meets the Technical Standard published by the Canadian Council of Motor Transport Administrators. This page covers who needs one and what happens when it fails.
Each commercial vehicle a motor carrier operates must have an ELD that meets the Technical Standard, mounted in a fixed position and visible to the driver in the normal driving position. The exceptions are vehicles that are:
operated under a permit;
operated by a carrier holding an exemption issued under the Act;
rented under an agreement of no longer than 30 days that is not an extension or renewal of a rental of the same vehicle;
manufactured before model year 2000.
The Technical Standard is the CCMTA’s Technical Standard for Electronic Logging Devices of April 11, 2019, as amended.
When an ELD malfunctions (s. 78)
The carrier must keep every ELD in good working order, calibrated and maintained to the maker’s or seller’s specifications.
A driver who sees a malfunction or data diagnostic code must tell the carrier as soon as the vehicle is parked.
The driver records in that day’s record of duty status the code, the date and time it was noticed, and when the carrier was told, and records the code on each following day’s record until the ELD is repaired or replaced.
The carrier must repair or replace the ELD within 14 days of learning of the problem, or at the latest when the driver returns to the home terminal from a planned trip that lasts longer than that.
The carrier keeps a register of malfunctions, and keeps the information for each ELD for 6 months after it is repaired or replaced.
