I 91 N near exit 18?
As you are aware, the speed limit for I 91 is 65mph. As you approach near exit 18 where the roads get divided to I 691 and route 15, the speed limit is 55 mph.
There is always a State Trooper in the middle of the highway on the grass during the night and I was pulled over on 74 mph as I did not notice the speed limit was decreased to 55 mph. So be careful guys.
