BETHLEHEM — Authorities say six members of a New York City family escaped serious injuries after their sport utility vehicle crashed and overturned on the Thruway outside Albany.

State police say the family’s 17-year-old son was driving the Mercedes Benz SUV when it crashed around 1:45 a.m. Friday off the northbound lanes of Interstate 87 in the town of Bethlehem, just south of Albany.

Troopers say a 7-year-old boy sitting unrestrained in a back seat was ejected from the vehicle when it overturned. Police say he suffered cuts and bruises.

His mother and 11-year-old sister also suffered non-life-threatening injuries. Police say they’re being treated at an Albany hospital.

The three other members of the Queens family weren’t injured.

Troopers say it was raining heavily at the time of the crash. The cause of the accident is being investigated.
