LA State Highway 165 between city limits and the Ouachita River Bridge, in front of the chemical plants
Speed limit drops sharply from 55 to 30 mph, police car usually concealed behind bushes or buildings. Tickets have been written for less than 10 mi. over limit. It’s possible out-of-state plates (this is near the Arkansas line) and likely out-of-towners are special targets. I have observed other motorists who couldn’t have been going very fast being pulled over, and have had a relative who said he was going right at 40 mph pulled over before he could slow down after noticing the posted limit change.
