Ferriday, Louisiana Speed Traps
Not just one place. All routes in and out of town
Small town with primary source of city income created by traffic fines. Most any non-local is a target, with out-of-state vehicles considered easy pickings. Travelers beware. Keep it under 25 regardless of the time of day.
US Hwy 65 north is a divided highway with 65 mph speed limit. When you enter the city limits the speed limit drops to 45, then 35, then 25, all still 4 lane. The cops hide in parking lots or anywhere else they can find and will ticket you for whatever they can. Small, poor town that uses this for much of their revenue.
