Ag truck owners reminded to record odometer readings and register for ag exemptions

Owners of Ag trucks are reminded to record their odometer readings on January 1 and report those to the California Air Resources Board (CARB) by Jan. 31 to maintain their Ag exemption.

CARB also reopened the registration period for those farmers who have not reported and claimed their ag exemption. Owners of agricultural trucks now have until Jan. 31 to register. Mileage limits have been streamlined and increased slightly. Farmers who already have the exemption do not need to take any further action.

The agricultural vehicle provisions include: delay compliance for vehicles that operate less than specified mileage thresholds and for a limited number of specialized trucks; apply to diesel trucks and buses with a manufacturer gross vehicle weight rating greater than 14,000 pounds, thus excluding pickups; include agricultural vehicles such as trucks and buses owned by log harvest operations or farming businesses and certain trucks that are not farmer owned but are dedicated to supporting agricultural operations; do not apply to truck tractors that enter ports or intermodal rail yards or transport marine cargo. These vehicles must comply with the Drayage Truck regulation.
