Plan to include a 10 minute break every two hours of driving. Have a good night's sleep before setting out on a long journey.
Remember the risks if you have to get up unusually early to start your trip, or have a long drive home after a full day's work.
Avoid making long trips between midnight-6am and 2-4pm when natural alertness is low.
Even a small amount of alcohol, some medicines and drugs can make you drowsy and you're in danger of falling asleep at the wheel.
When you are on your journey:
Take a 15 minute break every two hours of driving.
If you start to feel sleepy find a safe place to stop (not the hard shoulder of a motorway) as soon as possible.
Drinking 2 cups of coffee or other high caffeine drink and having a rest to allow time for the caffeine to kick in are effective methods of combating sleepiness.
