The driver of a tractor-trailer was killed Tuesday morning in an accident in Dundalk, Baltimore County police said.

The accident occurred just before 5 a.m., when the tractor-trailer left the road and crashed into a sign, a mailbox and four cars in a parking lot in the 3800 block of North Point Blvd., police spokeswoman Detective Cathy Batton said.
