The State - News from Aug. 22, 1989

The California Highway Patrol is marking the 17th year of its air-to-ground anti-speeder program, and the CHP reports its “air force” is alive and well around the state. “We do enough to keep the ground units busy,” said CHP Officer Earl Clemente, one of about 30 pilots who fly single-engine aircraft over the freeways around the state. Courts have ruled that the program is not a speed trap. Clemente explained that in designated areas, the CHP has laid out white hash marks a mile apart on the shoulder of the highway. By timing a car from one mark to another, officers aloft can determine a motorist’s speed.
