Men who drive blue BMWs are more likely to be aggressive than motorists in any other car, a study claims.
And the peak time for drivers to get angry is 5.45pm on a Friday as they fight the rush-hour – followed by the dismal Monday morning commute.
The likeliest road rage culprits are men aged 35-50 with blue BMW cars, the study of 2,837 motorists found. Drivers also reported run-ins with owners of Land Rovers, Audis, Subarus and Vauxhalls.
Blue was seen as the most aggressive colour, followed by black, silver, green and red.
Men said they lost their temper behind the wheel seven times a month on average, while women got angry on only three occasions.
Drivers most often expressed road rage by shouting and swearing, followed by erratic driving and obscene gestures, the study for discount website VoucherCodesPro revealed.
The poll also found, unsurprisingly, that Monday morning and Friday evening proved to be the most stressful times, when motorists are queuing to get to and from work.
Motorists were asked to pick the make and colour of car from which they have experienced the most incidents of road rage - and blue BMWs came out on top.
George Charles of VoucherCodesPro said: ‘During peak periods of traffic, whether it be the Monday morning school run or the hectic rush hour on a Friday evening, it is all too easy to allow the common manifestations of road rage to get the better of us as motorists.
‘This research, although slightly humorous in some of its findings, does indicate an important point.
‘Road rage is not something to be taken lightly and these results show that many motorists need to remind themselves that sometimes losing your temper whilst driving can result in serious altercations, assaults, and collisions that cause injuries or worse.’
