Link icon Refrigerated Van Provision


Owners of model years 2003 to 2009, 53-foot or longer refrigerated-van trailers, or box-type trailers with reefer units equipped with 2003 or newer model year transport refrigeration unit engines, may delay the SmartWay Low Rolling Resistance (LRR) tire and aerodynamic requirements as shown below. Fleet owners that have only refrigerated-van trailers meeting the criteria above are not required to register or report for this special provision:


  • January 1, 2018 - for a 2003 or 2004 model year trailer
  • January 1, 2019 - for a 2005 or 2006 model year trailer
  • January 1, 2020 - for a 2007 to 2009 model year trailer

(Note: Registering and reporting is required for fleets comprised of both dry- and refrigerated-van trailers that choose to follow either the optional Small Fleet or Large Fleet Phase-in Compliance Schedule.)
