It is kinda confusing how some of the off ramps in CT from the highways are the slow-vehicle lanes. One spot is on Route 8 northbound at 45, and some other ones on Route 9 in Haddam. Exit 9 for Route 81 is one of them.
Also, heading on I-84 West in Middlebury, the lane merge signs are placed in incorrect spots and in one spot when you head up over the arched bridge, the slow vehicle lane merges and there is no sign to warn you.
