CHP Officers with Lidar (Laser speed detector) aiming at cars speeding down the hill. Pay extra attention to anyone standing on the sidewalk. They could be officers with speed gun. The officers will simply wave you down to pull you over. I got busted once. Watch your speed going downhill (under 30mph is OK). The whole Saleroso Dr is CHP heaven for speeding tickets. The street is wider than most other residential streets and easily hit 40mph+ if you don’t pay attention.
