Shortly before 9:30 a.m., just north of the Havre de Grace exit in Maryland, a driver attempting to pass the charter bus lost control of his Honda Civic, and it veered across lanes of traffic and clipped the front of the bus. The bus overturned, smacked into an embankment, hit a tree, and came to rest across the roadway. Twenty-nine people were injured, two critically. The crash shut down the highway in both directions for hours.
