A Salem County woman died Wednesday when the car she was driving collided with a tractor-trailer, according to police.

Linda Krause, 81, of Elmer, was driving north on Burlington Road in Upper Pittsgrove and a heavy duty truck was heading east on Route 40 when the vehicles collided at the intersection around 9:30 a.m., a New Jersey State Police spokesman said.

Krause was killed and an 81-year-old passenger in her car suffered serious injuries, police said. The truck driver suffered minor injuries.

The cause of the crash remains under investigation.

Traffic on Route 40 has the right of way, while drivers on Burlington Road encounter stop signs at the intersection.
