U-Turns for Authorized Vehicles Only are put in all along the freeway E and W of Ritzville for aggressive enforcement of speeds. They have the U-Turn spots almost hidden from view but are posted with small signs. Watch for those. They also use rest stop ramps and intersecting freeway ramps, then sit back out of view. These actions are due to a heavy accident rate in the past. Very aggressive enforcement for 25-30 miles each way. Have a safe trip..
