Yes. A registered vehicle’s model year is established by the criteria set out by the National Highway Traffic Safety Administration (NHTSA). It is possible that the model year on the registration does not match the engine model year. This is commonly the case when the truck is reconstructed using a glider kit.
When this is the case, authorized safety officials should use the model year listed on the engine to decide if the driver must comply with the ELD mandate. In situations where the engine is older than year 2000, the driver does not have to follow the ELD rule.
In cases where the engine model year reflects that it was made in the year 2000 or later but the vehicle registration shows a model year older than 2000, the motor carrier must comply with the ELD mandate.
Drivers are not required to keep documentation that confirms engine model year. All information pertaining to the age of motors and engines must be kept at a motor carrier’s main place of business. If the engine age cannot be determined on the side of the road, law enforcement should consider investigating the case further with the motor carrier.
