MAKING deliveries, driving to work or dropping the kids off at school we all use cars for different reasons and encounter other drivers on a daily basis.

Most drivers will have been taken by surprise at some time as a young man in a sports car speeds past in the fast lane or 'white van man' pulls over without indicating.

Private motoring, home and leisure organisation, csma, which draws its membership from civil service employees and former employees, has carried out research which reveals who dislikes who on British roads.

The survey questioned a range of 2,000 adult drivers as part of the organisation's nationwide campaign for courteous driving.

Delivery drivers, commuters, Sunday drivers, parents on the school run and motorcyclists all gave some surprising responses.

Professional delivery drivers, often tagged 'white van man', are well known for sounding their horns and parking on double yellow lines. But who ruffles their feathers on the roads?

36 per cent chose taxi drivers as the least courteous type of driver.

19 per cent chose parents on the school run.

12 per cent nominated older drivers.

Commuters had a different view of the least courteous drivers:

25 per cent nominated taxi drivers.

21 per cent nominated young male drivers.

11 per cent chose HGV and bus drivers.

Weekend drivers can be annoying for keeping a careful eye on their speed. But who do they find least considerate on the roads?

29 per cent of weekend drivers chose young male drivers.

18 per cent chose taxi drivers.

11 per cent selected HGV and bus drivers.

Parents on the school run, who carry a precious load, identified a similar group of drivers:

29 per cent nominated young male drivers.

24 per cent chose taxi drivers.

13 per cent chose HGV and bus drivers.

Motorcyclists, who are always keen to avoid jams and slow-moving vehicles chose white van man as their least courteous fellow road user:

27 per cent chose professional delivery drivers.

18 per cent chose young male drivers.

9 per cent nominated other cyclists.

Gail Fee, marketing director of csma, said:

"Tolerance and courtesy can make an often frustrating driving experience much less stressful.

"By showing a little more consideration, we will reduce the effects of stress, making our roads a safer place."
