One or more LA County Sheriff’s Motor units will park on the south side of Foothill Blvd, west of San Dimas Avenue (usually west of Woodglen Drive)just past the crest of the hill as you pass Pinnacle Peak restaurant. They will have their laser guns out clocking the speed of cars as they crest the hill and come down, naturally building speed. The speed limit is 45 mph, but because cars are driving downhill, it is easy to reach speeds of 50 – 55 mph.

It should be noted this is a very wide portion of Foothill Blvd, with a bicycle lane on the westbound side of the street, and the Glendora Golf Course on the north side. There are no residences along the north side of Foothill Blvd in this stretch, and the residences on the south side are set back by a barrier of concrete and tall oleander bushes. Traffic usually is light to moderate. When the deputies stop cars, they usually catch up with them at about Amelia Avenue.
