An off-duty Boston police officer on his way to work collided with a Boston firetruck responding to an emergency yesterday in Mattapan. Boston Fire Department Ladder 29, based on Blue Hill Avenue, was on its way to a reported car accident and had its lights and siren activated at about 3:40 p.m.
When it reached the intersection of Harvard and Morton streets, it collided with a silver sport utility vehicle driven by the police officer, said Steve MacDonald, a spokesman for the Fire Department.
The momentum caused the 110-foot ladder truck to swing around and knock over a traffic light, MacDonald said.
According to State Trooper Brian Tully, the firetruck was driving south on Harvard Street, and when it approached Morton Street, it was struck on the left side by Vinson’s 2004 GMC Envoy. Vinson suffered a serious leg injury, and Tierney suffered minor injuries, State Police said.
The SUV, which is Vinson’s personal vehicle, was badly damaged and was towed away. The firetruck had front bumper damage from striking the traffic signal, MacDonald said.
