🔴 Knolls borders an active bombing range; stay inside the marked boundaries and do not ride past the area limits in any direction.
Permit required — $70 (7-Day pass, valid 8 days).
Mud flats can be soft underneath a hard-looking crust, especially after rain or in spring; getting buried out on the flats is a classic Knolls mistake.

Standard OHV rules (8)
Common equipment, registration and trail-use rules still apply.
Ride to the highest safety standard, not the legal minimum; a helmet, eye protection, a flag and proper gear are what get you home.
A properly installed spark arrestor is required; you must not operate an OHV without one.
🪖 Utah requires a DOT safety-rated helmet for anyone under 18 on public land on an ATV, motorcycle or snowmobile; everyone else is strongly advised to wear one.
Utah requires a red or orange whip flag, minimum 6 x 12 inches, when riding a sand dune area.
Under 18 you must be able to reach and work every control, hold a valid Utah OHV education certificate, and be under direct adult supervision.
Utah non-resident OHV permit required to ride public land: $30, valid 12 months; home-state registration does not replace it. Utah OHV registration is required for residents.

Fuel, food & local help
Local fuel notes (7)
EAST toward Salt Lake City: Sinclair at Delle, about 26 miles — the closest pump either way
WEST toward Wendover: a cluster of stops starting about 36 miles out. ⚠️ Wendover straddles the state line — the Utah-side stops come first, West Wendover is over in Nevada
🚚 TOWING? Head west.
Miller Travel Center and the Pilot are truck stops with pull-through lanes and the height for a toy hauler, both about 40 miles.
The Sinclairs are ordinary forecourts.
Arrive with a full tank and enough to get back out.
Carry water — there is none on site, no shade, and cell coverage on the flats is unreliable.
