It is easy to break the cool of Scottish drivers but motorists from Northern Ireland are least likely to let the stresses of the road affect them, a survey has found.
The poll by sat nav maker Navigon showed that 47% of Scottish drivers become angry if stuck in a traffic jam and 87% admitted to have sworn at another driver.
A passenger talking to them in the car would annoy around 10% of the Scots.
Northern Irish drivers are the most chilled out, with half of them rarely getting angry and over a third enjoying a CD on their journeys, the survey showed.
Yorkshire motorists are the most confident, with more than 40% saying they never lose their way on road trips.
The survey also found that 60% of Londoners wished the traffic on the roads would decrease.
Navigon's UK manager Peter Blampied said: "Driving any distance, particularly in bad weather, can be challenging.
"We hope this research will make drivers be more aware of other people's attitudes when taking to the road, especially in bad conditions."
