Interpreting and understanding road signs is a key part of driving in the UK. And there are plenty of them - the Highway Code lists hundreds of different signs, each with their own meaning.
Price comparison service Compare the Market put people's knowledge to the test by seeing how many common road signs they could identify. The research found that, on average, less than half - 47% - were matched correctly to their meaning.
The Department for Transport (DfT) says understanding traffic signs is "essential", not just for learners but "experienced professional drivers" too. "New road signs conveying new messages and in new formats are introduced from time to time, so drivers or riders who passed their driving test a few years ago need to keep up to date or run the risk of failing to understand or comply with recently introduced signs," says the DfT.
