Off-Road Vehicle (ORV) Unit

The Grant County Sheriff's Office is proud to provide public safety services to our off-road recreation communities. The ORV Unit currently consists of two full-time commissioned deputies who works with a number of community groups to ensure safe off-road recreation. The ORV Deputy travels the state educating users of the Sand Dunes and other areas as to the laws and safety equipment required in off-road activities. Memorial Day weekend is an example of one of the more active weekends and assistance from other agencies and deputies makes this a success, drastically reducing the number of accidents and calls for service.

Areas, Conditions & Laws Under Which You Are Allowed To Ride

  • Vacant Lots: Find out who owns the land and ask for their permission to ride on the land; if you don't, you are guilty of trespassing (going onto someone's property without their permission).
    • Just because there's not a fence around it doesn't mean you have the right to ride there.
    • The biggest complaint about ORVs running near houses is the noise and dust, the noise bothers everyone so don't ride near houses; clean air regulations govern the amount of dust that can be created, violations of clean air regulations can carry stiff fines
  • Washington State DNR, WDFW and some Private Land: (Department of Natural Resources and Department of Fish and Wildlife), ORVs are permitted on marked DNR and WDFW roads and trails. View the law as it pertains to Chapter 46.09 of the Revised Code of Washington Off-road and non-highway vehicles
