According to investigators, 37-year old John Boisseau of Sound Beach was driving a 2005 Chevrolet Trailblazer eastbound on the Long Island Expressway when he lost control of his vehicle, veered off the road and struck a tree near exit 55 in Brentwood at about 2 a.m. Friday.
Boisseau was ejected from the vehicle and landed beneath it.
Alex Mitchell, a truck driver who was also traveling eastbound, saw the crash, pulled over and moved Boisseau away from the Chevrolet just before it caught on fire.
The vehicle became fully engulfed and was extinguished by the East Brentwood Fire Department.
Mitchell, 37, of Ozone Park, was not injured.
Boisseau was transported to Southside Hospital in Bay Shore where he was treated for non-life-threatening injuries. He was arrested and charged with Driving While Intoxicated.
