Women more likely to swear when behind the wheel than men
One of the major causes for women turning air inside the car blue is satellite navigation systems which, according to the research, makes 55% of owners swear while using one.
More than a third of woman questioned also admitted that they would use foul language when they were 'cut up' by another driver, compared to just over a quarter of men.
The study also found that there is a large divide when it comes to the age of those using expletives behind the wheel. Over half (58 %) of those aged 20-29 swore when driving, compared with just 15% of those aged 40-49.
Direct Line car insurance spokesman Simon Henrick said: "People often use bad language during times of stress and many normally mild mannered people use expletives to express their irritation when behind the wheel.
"The concern is that the use of aggressive language and offensive gestures towards other motorists can escalate an already stressful situation and it can also quite feel intimidating for passengers in the vehicle."
According to the study, only one motoring incident irritated men more than it did women and that is when motorists use the overtaking lane when they are not overtaking. More than double the number of men (15%) than women (7%) admitted this makes them resort to bouts of bad language.
