Speed lilmit drops from 65 to 55 at the Isle of Palms exit. One has to well aware of that speed change. The Police cars sit on the right median waiting for their prey. They sometimes are in twos and threes. They are most evident in the early morning around 8AM and they are also there in the afternoon and evening rush hours.
