NTSB: Driver in fatal crash was speeding, had prior wrecks

BALTIMORE (AP) — The driver of a Baltimore school bus that careened into a transit bus, killing six people including himself, was speeding, had a history of previous crashes and had a seizure the week before, national investigators said Wednesday.

Glenn Chappell was driving about 57 mph in a 30-mph zone — nearly twice the speed limit — when he struck a Ford Mustang from behind before colliding with an oncoming Maryland Transit Administration bus last month, according to the National Transportation Safety Board's initial report.

[...] while Chappell had a medical certificate allowing him to drive the school bus, he had not filed it with the Maryland Vehicle Administration, which made it illegal for him to be driving the bus, the report said.
