AS FAMILIES plan weekend breaks through the summer months, driver training experts BSM are advising motorists to prepare carefully if they plan to be behind the wheel for any length of time.

BSM road safety expert Keith Cameron said: "Driving on congested roads for a long period can be a very stressful experience. Preparing properly before setting off and then observing a few simple rules will help ensure a more relaxed – and probably safer – journey."

BSM's top ten tips for long journeys are:

1) Plan your route in advance, allowing extra time in case of hold ups

2) Have a good night's sleep before the trip so that you don’t set off already tired

3) Check oil, tyres (including the spare), water and windscreen washer before setting off and carry a spare bottle of water in case the vehicle overheats

4) Carry something to keep young children occupied so that they will not cause distractions - games, tapes, CDs or even their favourite DVDs if you have a laptop

5) Keep the vehicle well ventilated right from the start of the journey. Don't wait until you feel drowsy before you open a window

6) Driving on motorways is a particular cause of drowsiness so don’t just stare fixedly in front of you - keep your eyes moving. By scanning well ahead, then in the middle distance and then to the rear and sides, you’ll be helping yourself stay alert as well as being prepared for any hazards around you

7) Your passengers can help you stay alert too, acting as map readers and hazard spotters and watching out for any signs of danger. They should be encouraged to insist that you take a break if you appear to be becoming tired

8) Take regular - and worthwhile - breaks every two hours. Simply stopping for a coffee is not an adequate break. Rest properly by also taking a short nap, then a walk and a quick wash. After the break, keep the car properly ventilated and give yourself time to acclimatise to the traffic conditions once again

9) If stuck in a traffic jam for any length of time, open all the windows and switch off the engine

10) Don't try discussing a jam busting change of route while on the move. Pull over in a safe place to study the map properly

Mr Cameron added: "If you're not used to them, long journeys on congested roads can be very exhausting. And, as is all too often seen, a tired driver can be a very dangerous one."
