Commercial vehicles such as tractor trailers and school buses must be operated by skilled drivers who are mentally and physically capable of performing their jobs safely. Prior Governmental Accountability Office (GAO) work has shown weaknesses in the Department of Transportation's (DOTs) oversight of Commercial Drivers License (CDL) holders, such as inadequate medical certifications for commercial drivers, which potentially put the public at risk. This book examines key controls designed to prevent medically unfit or impaired commercial drivers from operating commercial vehicles.
