Britain's Angriest Drivers – Region By Region

The research found that the most stressed drivers in Britain are those in the Midlands and Wales, but more Londoners have had their car deliberately rammed into than anyone else.

Only one in ten drivers felt embarrassed about their behaviour behind the wheel.

Although levels of driver stress differed around the country, motorists from every region were found in need of 'green driving techniques' to help them stay calm.

The ETA has found that aggressive driving not only adds to road danger, but lowers fuel efficiency. It is issuing the following simple advice during Green Transport Week (13-21 June 2009):

1. Avoid harsh acceleration and braking to save fuel, reduce wear and tear and feel more relaxed

2. Look as far as possible up the road to reduce stop/start driving, reduce fuel consumption and make you a safer driver

Director at the ETA, Andrew Davis said: "Congestion, fuel prices and other motorists are perennial causes of stress, but one in three drivers said it was simply the mood they were already in that was reflected in the way they drove. Those who follow our advice are likely to be safer, greener and financially better off into the bargain."

Driving traits by region:

Scotland: The least stressed drivers, but four times as likely as northerners to be involved in a violent road rage incident. The least likely to feel scared while driving, although one in five admitted to having taken a different route to feel safer

North: Least likely to be involved in a violent road rage incident, but over half admit to having been shouted or gestured at

Midlands and Wales: Young drivers (18-24) living here are the most stressed in Britain

London: The most likely to have had their car rammed in a road rage incident – four times as likely as drivers in Scotland. Most likely to have been shouted at (66%), but the least likely to admit to doing the same (33%)

By age: British drivers across all regions admitted their passengers had been surprised at how angry they become behind the wheel, although this was three times as likely to have happened to younger drivers as those aged over fifty-five.
