A Pilot Study of Sleep, Work Practices, Visual Processing Speed, and 5-Year Motor Vehicle Crash Risk Among Truck Drivers.

The purpose of this pilot study was to explore the relationships between sleep, work practices, speed of processing, and 5-year motor vehicle crash risk among a group of older truck drivers. Anthropometric, demographic, and psychological data were recorded, along with health, sleep, and work histories from a sample of 23 truck drivers. Results from this pilot study suggest that physical fatigue may play a role in processing speed.
