I have a job that requires I drive 60,000 mi per year in a car(sometimes SUV) in the snow belt. This has never been a big problem for me.
I would like to think this is just another example of liberal lunacy, but more likely its another tax disugised as a fine for some alleged wrong doing.
I'm willing to bet that the state of Massachusetts will raise almost ZERO revenue from this.
I suspect that the primary reason for this law is to assign formal legal responsibility in cases where cars are driving around with snow blowing off their hoods and trunks. A driver who is unwilling or unable to clear all the snow and ice off his vehicle will basically be unable to use an "act of God" defense in a civil lawsuit if a someone behind him is struck by flying debris from his vehicle.
