Steer clear if you see a blue BMW on your commute home, as new research claims that men driving blue models of that make of car are the angriest drivers on the road.
Research compiled by money-saving website VoucherCodesPro suggested men between the age of 35 and 50 were the most likely to suffer from "road rage", with BMW motorists ranked the most aggressive, ahead of those driving Land Rovers, Audis, Subarus and Vauxhalls.

In addition, motorists who drive blue cars were rated as the worst "road rage" offenders, and were more likely to be aggressive than those driving black, silver, green or red cars.
VoucherCodesPro's poll of 2,837 British motorists suggested that Friday evening after work was the peak time for drivers to lash out, followed by the Monday morning commute to work.

Nearly one-third (31 percent) of road rage offenders said that shouting or swearing was the most common way they expressed their anger. Others admitted to "driving erratically" or "obscene hand gestures", and 3 percent of offenders said they had stopped another car to confront the driver.
The research suggested that women aged between 17 and 25 were the least likely to be angry drivers, and Sundays were the calmest day of the week to drive.
Male respondents said they fell victim to other drivers' road rage 5 times per month on average, while women said they were victims an average of 8 times per month.

"This research, although slightly humorous in some of its findings, does indicate an important point," said George Charles, a spokesman for VoucherCodesPro.
"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, " Charles said.
