Behaviours

Statistics:

  • Seat belts were not worn by 5% of vehicle occupants killed or seriously injured*.
  • Speed was a factor in the crashes of 15% of people killed or seriously injured*.
  • At least one driver/rider blood alcohol concentration (BAC) of 0.05 or higher was recorded in 10% of fatal and serious crashes*.
  • At least one driver/rider with a BAC of 0.08 or higher was recorded in 8% of fatal and serious crashes*.
  • Fatigue could be responsible for up to 30% of deaths and a bigger percentage of serious injury crashes. Because fatigue is difficult to measure, it is under-represented in police crash data; however, research indicates that up to 30% of crashes involve fatigue.
