Peach Springs, Arizona Speed Traps
As you enter the Hualapai reservation from the south on Route 66 you cannot see the Tribal police that sit off the road on the left hand side across from the school. By the time you do it is to late. Obey the speed signs on the reservation as there are more places to hide than imaginable.
A grey unmarked Ford Expedition, a tribal cop which can enforce state laws, sits at the county/reservation line and runs traffic using radar.
