Middle lane motorway hoggers are one of the public's biggest irritations and contribute to congestion on the region's roads says a new report from the North West Highways Agency.

To raise awareness of the problems caused by motorway drivers who hog the middle lane, the Highways Agency has launched a DVD, presented by John Stapleton, called 'Stay Safe, Keep Moving.'

It advises drivers to keep to the left hand lane if the road ahead is clear and to return to the lane once the motorist has overtaken.

Mr Stapleton said: "I was out with the traffic officers and saw lines of cars in the middle lane, five, six, seven vehicles only using one lane of a major motorway.

"This type of driving holds other vehicles up, causing congestion, and also has safety risks.

"Middle lane driving encourages tailgating, dangerous in itself, and encourages people to make other unsafe manoeuvres such as undertaking."

The new DVD is backed by the AA and the RAC Foundation.

'Stay Safe, Keep Moving' forms a part of a new road safety DVD from the Highways Agency and can be viewed on the internet on the Public TV website HERE.
