It is estimated that 10 to 15 percent of traffic accidents are (partly) related to fatigue.
The above estimate is made by the Road Safety Research Foundation on the basis of foreign studies. A study has been conducted in America that shows that the chance of a collision doubles if you have built up a sleep deprivation of one to two hours within 24 hours.
Have you only slept four to five hours?
Then the chance of an accident would be 4.3 times greater. With less than four hours of sleep, that increases to 11.5 times as much risk of an accident.
