Recreational vehicle (RV) manufacturer and dealer agreements

You can't sell new RVs in Washington to or through a dealer without first entering into a written agreement with them. The agreement must:

  • Establish regulations and provisions for both parties.
  • Provide obligations for warrantors of RVs, RV parts, components, and accessories.
  • Outline a clear process for civil dispute resolutions, mediation, and relief if you're injured by another party’s violations.
  • Be signed by both parties.

The law defines RVs as:

  • Vehicles towed by a consumer-owned vehicle, and
  • Designed to provide temporary living quarters for recreational, camping, or travel use. Examples include:
    • Only travel trailers.
    • Fifth-wheel travel trailers.
    • Truck campers.
    • Folding camping trailers.

Clean car emission requirements

Required emission standards

Starting with 2009 models, the following vehicles must meet California emission standards:

  • New and used passenger cars.
  • Light-duty trucks.
  • Medium-duty passenger vehicles.

These vehicles must be certified to at least one of the following emission standards to be registered, leased, rented, licensed, or sold for use in Washington:

Vehicles that are "federally certified" or "certified to meet EPA standards" aren't certified to California emission standards and don't meet Washington requirements.

Required reports

Washington law requires automakers to submit 2 Non-methane Organic Gas (NMOG) Fleet Average Compliance Reports to the Department of Ecology by March 1 each year.

Automakers that aren't in compliance with the fleet average requirement must also submit a Fleet Average Enforcement Report.

Warranties for zero-emission vehicles

Washington doesn't require automakers to offer additional extended warranties for sales of zero-emission vehicles like California. However, the Department of Ecology encourages automakers to offer and honor those extended warranties voluntarily as a service to their customers.
