The Truck & Bus Regulation also does not apply to the following vehicles, but these vehicle types may need to report in the Excluded Diesel Vehicle Reporting (EDVR) system to avoid DMV registration denial:

  • Vehicles that have been converted to gasoline or dedicated natural gas vehicles.

  • Vehicle used exclusively for towing a habitable trailer for non-commercial private use.

  • Motorhomes used for non-commercial private use including vehicles converted to a motorhome. “Motorhome” means a single vehicular unit designed for human habitation for recreational or emergency occupancy and built on, or permanently attached to, a self-propelled motor vehicle chassis, chassis cab, or van, which becomes an integral part of the complete vehicle or a vehicle that exclusively tows a trailer that was originally designed for human habitation for recreational or emergency occupancy.

  • Pick-up trucks with a GVWR of 19,500 lbs or less with a pick-up bed used exclusively for personal, non-commercial, or non-governmental use.



The Truck & Bus Regulation does apply to the following vehicles, but these vehicle types may need to report in the Excluded Diesel Vehicle Reporting (EDVR) system to avoid DMV registration denial before the accurate deadline:


  • 2010 or older chassis with original or repowered engine year that is the same year or newer than the chassis. Engines are manufactured separately from the vehicle chassis and typically are one year older than the vehicle model year. The Regulation regulates the engine model year but DMV registration will be denied based on vehicle model year, with the assumption that vehicle model year is one year newer than the engine model year.
