What does the 'move over' law in Massachusetts require drivers to do?

Answer: B — Change lanes or slow down for emergency vehicles

The 'move over' law in Massachusetts requires drivers to change lanes or slow down when approaching emergency vehicles that are stopped on the side of the road with their lights flashing. This law is designed to enhance the safety of emergency responders and other roadside workers by encouraging drivers to create a safer environment. By changing lanes or reducing speed, drivers help minimize the risk of accidents and injuries that could occur if they continue driving at regular speed past stationary emergency vehicles. The context in which this law is applied emphasizes the need for cautious behavior around emergency situations. Drivers should always remain aware of their surroundings and be prepared to respond appropriately when they encounter emergency vehicles, ensuring both their own safety and that of the responders.
