East Hampton Town officials are reminding visitors and residents to follow New York State's Move Over Law this holiday weekend.
With temporary signs set out to press the point home, the law requires drivers to slow down and safely move over for law enforcement officers, emergency responders, tow truck operators, highway crews, and utility workers.
Ambulance volunteers use green lights, as do members of the Volunteer Ocean Rescue squad. Firefighters use blue lights when responding to an emergency. Red and blue lights together indicate law enforcement and official emergency vehicles.
"These courtesy lights request the right of way so volunteers can reach emergencies quickly and safely," a press release said. "Drivers should stay alert, check mirrors often, and yield when they see flashing red, blue, or green lights. When you see these lights move over or move right."
