A tractor trailer burst into blames following a collision with another tractor trailer at the Kennbunk rest area on the Maine Turnpike Saturday night.

Maine State Police said Don Johnson, 78, of East Corinth may have suffered a diabetic seizure as he was exiting the turnpike into the rest area at about 8:30 p.m. His truck crashed into a parked tractor trailer operated by Myles Whynot, 58, of Quipamsis, New Brunswick.

Both drivers were treated for cuts and bruises at Southern Maine Medical Center in Biddeford.

The diesel fuel tanks ruptured and ignited on impact. Other motorists at the rest area freed Johnson from the truck before the fire reached the cab. Johnson’s dog was killed in the fire.

Johnson’s truck was empty and Whynot’s was hauling a plow assembly. Both trucks were destroyed, police said.

The rest area remained open throughout the incident, police said.
