Fatigue and driving

DROVE TOO LONG DRIVER SNOOZING WHAT HAPPENED NEXT IS NOT AMUSING 

Although we all know it when we feel it, fatigue is not that easy to define. Nearly sixty years ago, Bartley and Chute (1947, as cite by Brown, 1982) attempted to define fatigue by a list of what it is and what it isn t. This list of identifying features is reproduced in Table 14-1. 

It is always directly experienced -impairment is not necessarily so It is not identical to impairment - one can be fatigued and not show impairment and vice versa 

It is a personal experience related to a person s self-evaluation and present and past experiences It cannot be measured by impairment 

It is cumulative It does not depend crucially on energy expenditure
