A new study by Zurich Insurance has revealed that one in three British motorists say they have been victims of road rage in the past three years.
And one in seven have been chased by another driver.
That's around 10million motorists having to put up with another irate driver.
And, worryingly, one in ten had another motorist pull over or get out of their car to confront or threaten them.
While 64 per cent of drivers admitted to some kind of aggressive behaviour, more than three-quarters of these felt that their actions were justified.
Evening rush hour is worst for aggression, while roads near schools are the most stressful places to drive.
The study has also revealed that the worst area for road rage is East Anglia, while the safest is South-East England.
