The Institute of Advanced Motoring (IAM) has called on the government to step up its efforts in maintaining council roads, warning that current damage could be leaving motorists at risk.
It comes after new figures published by the Department of Transport revealed that the condition of council roads had failed to improve between 2008 and 2011.
The councils with the largest percentage of main roads requiring maintenance were found in Haringey and Camden, where around one in five highways were found to be in need of repair.
Newham council was the worst when it came to repairing minor roads, with a similar ratio of one in five found to require improvements.
Of the 89 councils that provided data, a total of 40 per cent reported a deterioration in main road conditions with 38 per cent enduring similar problems on minor roads.
Commenting on the findings, IAM director of policy and research Neil Greig called on the government to commit to long term council funding to deal with the repairs.
“Poor road conditions damage vehicles, and are especially dangerous to cyclists and motorcyclists who can be easily thrown off course by potholes," he said.
"They also put all road users at risk, as drivers take evasive action to avoid hitting them.”
