Enforcement is moderate on 16W until Starke city limits where laser is used. Speed limit is 60 mph west of Camp Blanding till just outside Starke, then speed limit changes suddenly to 50 and again very quickly to 40 on a curve. Sitting on the curve next to a church westbound toward Starke is where the city police sit. The signs are very close together. The only rational thinking is this is a speed trap. 50 mph to 40 mph is where the trap is. At 55 mph with cruise control on, the change is so sudden, you don’t have time to even release the control before you’ve gone by the 40 mph sign and they gotcha with laser. For big truck info: there is also a sign stating no engine brakes within city limits. So when driving a big truck in that vicinity slowing your speed from 55 mph to 40 mph, with a load is almost impossible without the jake brake and they will cite you for using it…if this isn’t a speed trap what is it??? It’s not fair to anybody driving on that road big truck or car, but it’s a way for the city to make money.
