This is set up for vehicles heading south on Rosemead Blvd. from Temple City into Rosemead. You will cross under the railroad and on the upside is when they’ll get you if you’re speeding. It is quite usual for morning traffic and can be more than one officer using his radar. They use the parking lot on the right and "hide" behind some shrubs…easy to spot once you know their spot. Once you pass Lower Azusa you’re out of danger.
