The town has put up signs in crosswalks saying the fine is $200 for failure to yield, but there is no enforcement and many drivers do not stop even when pedestrians are in the crosswalks. This morning I was crossing N Main at North with southbound traffic stopped and a van from the Middlesex County Courts Community Service program (license M518) was traveling northbound at a rate of speed the RMV would not classify as reasonable and proper. He did slam on his brakes to let me cross, but as soon as I was clear he stomped on the gas and sped off while 2 women were crossing the southbound side about to enter the northbound side. At the same intersection last week, a van from JECORP stopped and let me cross N Main, but he drove in front of me while crossing North. If he has a dent in the side I will neither confirm nor deny that I swung the book I was carrying. The crosswalks are clearly marked, there are signs warning of penalties, and there are people crossing at each one trying to get to the commuter rail station; but there is no enforcement and therefore no credible threat by these signs. Writing a couple of tickets once in a while might make drivers think twice (or maybe even once) about how to treat pedestrians in a crosswalk.
