Your headlights and tail lights need to be on whenever your windshield wipers are needed.
New law, M.G.L. c. 85, sec 15, effective April 7, 2015.
A new Massachusetts law, effective April 7, 2015, states that drivers must turn on their headlights and tail lights when visibility is 500 feet or less, or when the windshield wipers are needed. Police officers can now pull over drivers for failing to follow the new law. This can result in a ticket AND an insurance surcharge. The new law is set to improve road safety when visibility is effected by poor weather conditions, even during daylight hours.
