Fatigue

Don't drive tired

Studies have shown that drivers don’t fall asleep without warning. Drivers who fall asleep at the wheel have often tried to fight off drowsiness by opening a window, or by turning up the radio. This doesn't work for long.

The facts

  • Research suggests that almost 20% of accidents on major roads are sleep-related
  • Sleep-related accidents are more likely than others to result in a fatality or serious injury
  • Peak times for accidents are in the early hours and after lunch
  • About 40% of sleep-related accidents involve commercial vehicles
  • Men under 30 have the highest risk of falling asleep at the wheel

THINK! Advice



Plan your journey to include a 15-minute break every two hours.


Don't start a long trip if you're already tired.


Remember the risks if you have to get up unusually early to start a long drive.


Try to avoid long trips between midnight and 6am when you're likely to feel sleepy anyway.


If you start to feel sleepy, find a safe place to stop - not the hardshoulder of a motorway. Drink two cups of coffee or a high-caffeine drink and have a rest for 10 to 15 minutes to allow time for the caffeine to kick in.


Remember, the only real cure for sleepiness is proper sleep. A caffeine drink or a nap is a short-term solution that will only allow you to keep driving for a short time.
