Each page below starts from the one DMV rule that sets that vehicle apart. 4.7 stars from 550 Google reviews of the two Reno Xpress Oil & Lube Centers Two things move a vehicle off the ordinary path: its weight class or fuel changes the test method, or it appears on the DMV's exempt list. Here is the one-line rule for each type, with the full page a click away. ## The seven rules in one line each Motorhomes and RVs: gasoline coaches are tested at any weight, with the two-speed tailpipe test; diesel coaches over 14,000 pounds GVWR are exempt from the yearly test. Motorcycles and mopeds: on the DMV exempt list by name. Heavy-duty gas trucks: 8,501 pounds and up is heavy duty, tested every year with the two-speed tailpipe method. Pickup trucks and vans: the 8,500 pound line decides the OBD plug-in test or the tailpipe test, and diesel pickups up to 14,000 pounds GVWR test too. Leased vehicles: tested every year like any car; a transfer between leasing companies with no change of lessee or operator is exempt (NRS 445B.800). Replica vehicles: Replica Vehicle registrations are on the exempt list. Propane and natural gas vehicles: vehicles running permanently on propane, CNG, methane or butane are exempt. ## Large vehicles at the Reno locations For a motorhome, a large truck or a diesel, call the service center before you bring it: Reno Northwest (775) 787-1000 or Reno South (775) 828-6996.

Call either Reno location or just drive in; there is no appointment to make. ### My vehicle is not one of these seven. Which rule applies? The ordinary one: a gasoline vehicle 1968 or newer, based in the testing area and past its third registration, tests every year at renewal. ### Does an exempt vehicle still renew its registration? Yes. The exemptions cover the emission test only. ### Where do I find my vehicle's weight rating? On the manufacturer's label, usually on the driver's door jamb.
