In Massachusetts the Move Over Law aims to make police, firefighters, paramedics, tow truck drivers, and all roadside emergency and maintenance professionals safer on the job. The Move Over Law, which took effect March 22, 2009, requires drivers approaching a stationary emergency or maintenance vehicle with flashing lights to move to the next adjacent lane if it is safe to do so, and, barring that, to reduce their speed. Failure to comply could result in a fine of up to $100.
