NORTH BERWICK, Maine (AP) — The driver of a tractor-trailer that collided with Amtrak’s Downeaster in Maine had a checkered driving record that included two citations for unsafe operation of a commercial vehicle.

The New Hampshire Department of Public Safety says Peter Barnum of Farmington, N.H., also had six speeding tickets and one seatbelt violation in New Hampshire and Massachusetts from 1992 to 2009. In addition, Maine officials say he was cited twice for speeding.

New Hampshire spokesman Jim Van Dongen said Barnum had only one accident and no license suspensions. He described Barnum’s driving record as spotty but “not disastrous.”

His record over the past two years was clean.

The truck driver was killed in Monday’s fiery collision in North Berwick. Four passengers, along with the Amtrak engineer and an assistant conductor, were injured.
