A mother and her 2-year-old daughter suffered serious injuries when their vehicle collided with a dump truck in Standish.

It happened Wednesday afternoon on Route 113. A vehicle operated by 32-year-old Rebecca McVety of Standish collided head-on with a Leavitt Earthworks dump truck that was fully loaded with dirt.

A LifeFlight helicopter transported McVety to Maine Medical Center with life-threatening injuries.

The toddler suffered serious injuries and was taken to the hospital by ambulance.

The driver of the dump truck was not hurt.

The Cumberland County Sheriff’s Office said McVety’s vehicle apparently crossed the centerline into the path of the dump truck. They’re investigating whether distracted driving was a factor in the crash.

Route 113 near the intersection with Route 25 was closed to traffic for nearly five hours due to the wreck.
