If you see a driver swearing in front of kids in the car or flipping people off, it's most likely to be a woman.
A recent survey of 1,000 adults, commissioned by Insurance.com, asked about their rude driving behaviour. The survey found women were more likely to respond to driving frustrations by swearing, brake-checking or "flipping someone off" than men are.
But men were no angels either. The survey found they are twice as likely as women to key someone's car or flash drivers with their high-beams just to be mean.
Here's what drivers admit to, with results broken down by gender:
Honked at someone driving too slowly: 41 per cent
(Women: 39 percent. Men: 43 per cent.)
Swore in front of the kids while driving: 37 per cent
(Women: 44 per cent. Men: 30 per cent.)
Flipped someone off while driving: 29 per cent
(Women: 31 per cent. Men: 27 per cent.)
Brake-checked a car following too closely: 28 per cent
(Women: 30 per cent. Men: 27 per cent.)
Sped up significantly to prevent someone from passing you: 26 per cent
(Women: 25 per cent. Men: 28 per cent.)
Gone when it wasn't your turn at a four-way stop: 19 per cent
(Women: 18 per cent. Men: 20 per cent.)
Tailgated someone on purpose because he or she was going too slowly: 18 per cent
(Women: 21 per cent. Men: 16 per cent.)
Driven to the front of a merge line, then swerved and cut in: 12 per cent

(Women: 3 per cent. Men: 7 per cent.)
Swearing and bird-flipping behaviours are most likely confined to the car, Insurance.com notes, quoting psychology professer Leon James of the University of Hawaii, who has researched driving behaviours.
"Different rules apply to different places," he says. "The car gives us the illusion of being alone and safe in our fortress. If we do something ugly or inconsiderate we can always get away. (It's) different when standing in line with others who are right there next to us."
Our socialization and culture also influence how we act behind the wheel, says James.
"Our driving behaviour styles are culturally determined. I call the back seat of the car 'road rage nursery.' That's when our driver education begins. We absorb how the parents or other adults drive and how they talk and complain behind the wheel," he says. "We also watch TV scenes and commercials where driving aggressively, fast and with plenty of verbal rudeness are portrayed as attractive and satisfying. So, getting behind the wheel changes the rules."
Additionally, driving is often viewed as a competitive activity, which makes people behave more aggressively than they otherwise would.
"Drivers have acquired the philosophy that in such competitive social situations it's alright to do whatever one can to beat out the others," says James, "whether it's the trip time, or getting into the fastest lane and switching around, or driving on the shoulder and getting ahead of everyone."
