• you have planned your route and allowed sufficient time
• clothing and footwear do not prevent you using the controls in the correct manner
• you know where all the controls are and how to use them before you need them. All vehicles are different; do not wait until it is too late to find out
• your mirrors and seat are adjusted correctly to ensure comfort, full control and maximum vision
• head restraints are properly adjusted to reduce the risk of neck injuries in the event of an accident
• you have sufficient fuel before commencing your journey, especially if it includes motorway driving. It can be dangerous to lose power when driving in traffic.

• you MUST NOT tow more than your licence permits you to
• you MUST NOT overload your vehicle or trailer. You should not tow a weight greater than that recommended by the manufacturer of your vehicle

• you should properly distribute the weight in your caravan or trailer with heavy items mainly over the axle(s) and ensure a downward load on the tow ball.

If this does happen, ease off the accelerator and reduce speed gently to regain control.

80: Driving when you are tired greatly increases your accident risk. To minimise this risk

• make sure you are fit to drive. Do not undertake a long journey (longer than an hour) if you feel tired
• avoid undertaking long journeys between midnight and 6am, 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. Do not stop on the hard shoulder of a motorway
• the most effective ways to counter sleepiness are to take a short nap (up to 15 minutes) or drink, for example, two cups of strong coffee. Fresh air, exercise or turning up the radio may help for a short time, but are not as effective.

81: Vision. You MUST be able to read a vehicle number plate from a distance of 20.5 metres (67 feet - about five car lengths) in good daylight. From September 2001, you MUST be able to read a new style number plate from a distance of20 metres (66 feet). If you need to wear glasses (or contact lenses) to do this, you MUST wear them at all times whilst driving.

83: Do not drink and drive as it will seriously affect your judgement and abilities. You MUST NOT drive with a breath alcohol level higher than 35 µg /100ml or a blood alcohol level of more than 80 mg/100 ml. Alcohol will

• give a false sense of confidence
• reduce co-ordination and slow down reactions
• affect judgement of speed, distance and risk
• reduce your driving ability, even if you are below the legal limit
• 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. If you are going to drink, arrange another means of transport.
  Law RTA 1988 sects 4, 5 & 11(2)

84: You MUST NOT drive under the influence of drugs or medicine. Check the instructions or ask your doctor or pharmacist. Using illegal drugs is highly dangerous.
