Charlottetown police say driver error and a visual obstruction contributed to a fatal accident north of the city in March, and no charges will be laid.

A mother and daughter from St. Teresa died March 12 when the car they were in was struck by a tractor-trailer. The car was making a left turn at the intersection of the Malpeque Road and the bypass highway near Sears

The female driver of the car survived, and is still recovering from her injuries.

"This is a very tragic incident and the driver in this case, there is no criminality and we impressed that upon her. We do know that excessive speed and alcohol were not factors," said deputy police chief Richard Collins.

"The two victims, Donna Trainor and Crystal Trainor, were both wearing their seat belts at the time, however the impact was so severe it negated the safety features of the seat belt. In relation to contributing factors, it would appear that driver error, inattention, visual obstruction, were contributing factors to this accident. However it was definitely nothing that would warrant any criminal charges."

Collins said there was a cube van at the intersection at the time of the collision, which likely caused a visual obstruction for the driver of the car.
