A staggering half of British drivers have admitted that their road knowledge is so poor they canâ€™t identify simple road signs.
Road safety charity IAM RoadSmart has revealed that a full 50 per cent of people it questioned couldnâ€™t correctly identify the sign for a roundabout.
And more than two thirds said they didnâ€™t understand the two-second rule set out to help motorists keep a safe distance.

In a poll of more than 1,000 drivers, the UKâ€™s largest road safety charity found that 68 per cent were unaware of the recommended two-second gap for dry-weather driving, with 53 per cent confusing it for two car lengths. At 60mph this results in a gap of less than a third of a second – nowhere near enough to avoid a collision.
The survey of driversâ€™ knowledge also found that 57 per cent didnâ€™t recognise the â€œdual carriageway endsâ€ sign and only a third knew that the cats eyes between a motorway and its slip road are green.
Neil Greig, IAM RoadSmart director of policy and research, said: â€œThis is truly shocking. The outcome of the survey brings to light some frightening statistics which demonstrates the need to constantly refresh on-road knowledge.
â€œWith many young drivers showing high levels of traffic sign ignorance these results reinforce IAM RoadSmartâ€™s view that road safety education should be taught as part of the National Curriculum in schools to prepare teenagers for their future driving career.
â€œMany drivers donâ€™t look at the Highway Code regularly after theyâ€™ve passed their test, but no-oneâ€™s memory is perfect and itâ€™s crucial to read and understand the most recent version of the Highway Code for the safety of all road users.â€
