Fatigue hits young drivers.

A comparison of the driving skills of people aged under 25 with the skills those in their 30s indicates that fatigue has a greater effect on younger drivers. University of Queensland psychologist Simon Smith used a driving simulator to test the skills of drivers at different times of the day. According to Dr Smith, the older drivers were 'much less affected by sleepiness' than those aged under 25. 'Young people have very good reaction time but they're very poor at deciding what to react to. That comes with experience', Dr Smith said (Courier Mail, 3/09/07, p.18).
