On April 7, 2015, a new law in Massachusetts goes into effect that requires you to put your headlights on whenever you turn your windshield wipers on or when there reduced visibility such as fog. The purpose is for safety, to make you more visible to other drivers from the front and rear. Even vehicles with automatic daytime running lights (DRL) are required to put their full headlights on because the daytime running lights only light the front lights. This will turn on your rear lights, making the rear of your vehicle visible to approaching drivers. Drivers can be stopped, ticketed, and could face surcharges on their insurance.
