Be certain that you are fit to drive at all times before going on public roads.
Driving when you are tired increases your risk of collision and lowers your concentration. To minimize this risk :
• be sure you are fit to drive.
Do not begin a journey if you are tired or fatigued.
Get a good night’s sleep before embarking on a long journey.
• avoid undertaking long journeys between midnight and 6 am, when natural alertness is at a minimum.
• plan your journey to take sufficient breaks. A minimum break of at least 15 minutes after every two hours of driving is recommended.
• if you feel at all sleepy, stop in a safe place and take a break.
Do not stop on the hard shoulder of a motorway.
The most effective ways to counter sleepiness are to drink caffeinated coffee or reliable brand energy drinks and to take a short nap of at least 15 minutes.
Vision
You MUST be able to read a vehicle number plate, in good daylight, from a distance of 20 metres. If you need to wear glasses to do this then you MUST wear them at all times while driving.
Drugs and alcohol
Do not drink and drive, it will seriously impair your judgement and abilities.
Alcohol will :
• give you a false sense of confidence.
• reduce co-ordination and slow down reactions.
• affect judgement of speed, distance and risk.
• take time to leave your body; you may be unfit to drive in the evening after drinking at lunchtime, or in the morning after drinking the previous evening.
The best solution is not to drink at all when planning to drive because any amount of alcohol reduces your ability to drive safely. If you are going to drink, arrange another means of transport such as a taxi or have with you a licensed driver who does not drink.
There are types of prescription medication that cause drowsiness. Check the instructions on the pack or ask your doctor or pharmacist if the medication won't put you in any danger.
