Conclusions

  • Fatigue-related crashes are often associated with high injury levels
  • Fatigue is a major factor in a large proportion of road crashes (range 10-20%)
  • Several studies suggest that fatigue is associated with increased crash risk
  • The increased risk often results from a combination of biological, lifestyle- and work-related factors
  • More scientific evidence is needed concerning the exact quantitative relationship between fatigue and risk.
