Operator fatigue and sleep deprivation have been widely recognised as critical safety issues that cut across all modes in the transportation industry. However, there are a number of additional safety issues that plague drivers in a variety of vehicles. This book examines the safety issues that affect many types of transportation, such as improvements to drug testing programs in order to promote motor carrier safety, driver fatigue research, driver factors in fatal bus crashes and the role of driving-hours on driver fatigue. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.
