Grant County ORV Facilities:

Some of the Users of the Moses Lake Sand Dunes

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.

Alcohol is prohibited in the Moses Lake & Beverly Sand Dunes.


It is also unlawful to operate an ORV on roadways.

In particular the main Sand Dunes Rd in Moses Lake.

Grant County 4WD & ORV Communities:



Areas, Conditions, and 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 ORV's running near houses is the NOISE and DUST. The noise bothers everyone. 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) - ORV's are permitted on marked DNR and WDFW roads and trails. View the law as it pertains to:

  • Chapter 46.09 RCW - Off-road and non-highway vehicles

Any person can operate any ORV on DNR and WDFW roads and motorized trails with the following:

  • Current License Plate or ORV Tag

  • A working muffling system (emitting no more than 105 decibels at 20") with a "USFS Approved Spark Arrester" that is stamped into the metal on motorcycle mufflers and is clearly visible

  • Head-light(s) and tail-light(s) are required during the hours of darkness

  • Brakes and Brake-light(s).

  • RCW.46.09.460 specifies that no child under 16 years of age may operate and ORV without adult supervision and the adult must possess a valid license to operate a motor vehicle.

  • RCW.46.09.470 (3)(a) Helmet use. Except for an off-road vehicle equipped with seat belts and roll bars or an enclosed passenger compartment, it is a traffic infraction for any person to operate or ride an off-road vehicle on a nonhighway road without wearing upon his or her head a motorcycle helmet fastened securely while in motion. For purposes of this section, "motorcycle helmet" has the same meaning as provided in RCW 46.37.530.

Areas, Conditions, and Laws Under Which You Are NOT Allowed To Ride:

  • Roadways: Only licensed street vehicles may ride on, cross or ride the shoulders/ditches of roadways.

  • Canals: Riding along canals is prohibited. These roads are for maintenance and canal operations.  If you are on them, you are guilty of trespassing.
