New research has found that tailgating, the practice of driving too close to the vehicle in front, is the most irritating behaviour for drivers, most likely through a fear of a rear end collision should they need to brake suddenly.

The research, from the Institute of Advanced Motorists (IAM), showed that 28% of those questioned put tailgating at the top of road irritations followed by people using a mobile phone while driving and motorists hogging the middle lane on a motorway.

70% said that they got angry with other road users with 28% saying that their own driving was affected by them getting angry with another driver.

Neil Greig, IAM director of policy and research, said: "It is good to see motorists disapproving of bad driving, especially mobile phone use, which is on the rise, but it's worrying that so many still get angry when driving. It's all about self-control - good drivers spot the signs of potential road rage and do everything they can to steer clear of it."
