James Byrnes, 26, of 8 Mill Lane, was charged with leaving the scene of an accident and driving while impaired by drugs, police said.
Byrnes took off at a "high rate of speed," police said, and several witnesses called 911 with details of his car.
A Good Samaritan team of husband and wife followed Byrnes in their car, police said, and a short time later on the southbound William Floyd Parkway, the couple spotted a patrol car at 12:19 p.m.
At that moment, Byrnes had stopped for a red light at McGraw Street, police said. Dewitt gave Byrnes field sobriety tests and made the arrest.
