Interstate 91 near Exit Number 17 – 20
The area between Springfield, MA and Greenfield,MA on I91 North & South motorists should be especailly careful and not exceed the posted speed limit. The worse area is from Exit 17 (near Holyoke, MA) to Exit 20 (North Hampton,MA). The state police seem to significantly patrol (swarm) in those areas. Stated speed limits seem to be strictly enforced. State police will follow you, use laser or radar to catch drivers. Police seem to like holiday weekends and Thursday-Saturday nights to setup numerous traps in that area. Just because you have passed a car pulled over, there maybe many more traps ahead.
