Motorists who dawdle at traffic lights annoy more people than bullying bus drivers, middle-lane motorway hoggers and caravans, it was revealed.

We asked 500 motorists what frustrates them about life on Britain's open roads, with a general lack of urgency at green lights infuriating most.

Surprisingly, twee car stickers - including the slogans 'sprinkled by fairy dust' and 'cheeky monkey on board' - came third in our 'Driver Frustration' survey.

Motorway middle lane hoggers came second in our top 10 list of irritations, with mobile phone usage while behind the wheel fourth and people failing to indicate fifth.

We launched the questionnaire as a light hearted attempt to engage with motorists, following a similarly intriguing poll in 2009, which revealed that a failure to acknowledge other road users when being given right of way was motorists' number one annoyance.

Marketing manager Geraldine McGovern said: ""We were surprised to see the results, particularly as there was no mention of traffic wardens or speed cameras, which we thought would be the cause of major frustration."
