POOR map reading with lack of clear directions, back seat driving and dangerous manoeuvres, are the most frequent causes of arguments on long car journeys, according to men.

This is the result of research by Virgin Cars.Trigger points for arguments in the car, according to women, are speed, the driver getting lost, as well as incompetent map reading.

Men and women agree that a discussion about relatives, particularly ones you may be visiting, can also lead to some arguments.

To make journeys smoother, Virgin Cars offers the following advice:

* Before leaving, dig out the handbook and check that all the tyre pressures are correct.

* Check all fluid levels and top up as necessary.

* Plan the route in advance and listen to a travel bulletin before setting out to try to avoid any known traffic bottlenecks. Make sure you have an up-to-date map in the car with you.

* Drive at speeds appropriate to the weather conditions.

* Decide in advance how often and where you will stop - it should be every two hours or so.

* Don’t set out in driving rain or high winds unless the journey is essential.

* Don’t forget to take enough food and games to keep children amused.

* Don’t run your car on a near empty fuel tank - running out of petrol is no fun and dregs in the tank are bad news for your car.

n Don’t forget to tidy the car before you set out: rubbish rolling about in the car can be distracting.

Ian Lancaster, chief executive of Virgin Cars, said: ““As an independent retailer we offer a huge range of cars to meet these needs, all of which come with the comprehensive after sales care that you would expect from the Virgin brand.”
