We all had to learn the meaning of road signs to pass our driving tests; we see them every time we drive and they are vital to road safety, but how many of us actually remember what all the different road signs mean?
A poor understanding of The Highway Code is compromising road safety, a new survey has revealed. Results from the poll of 5,000 motorists showed a large percentage failed to correctly answer a number of general knowledge and picture questions covering road signs and The Highway Code.
One in six drivers have ignored road signs when they do not know what they mean, Goodyear's Test the Nation survey found.
The study tested 2,000 drivers on road rules and signs and found that while almost half rated their knowledge of the Highway Code as good or very good, that was not the case.
More than four in 10 (44%) drivers could not correctly identify that a red and amber traffic light shown together meant stop, Goodyear's Test the Nation survey found. Instead they thought it meant to proceed with caution.
Almost three out of 10 did not think it was necessary to stop if a pedestrian was at a zebra crossing waiting to cross, while more than a quarter did not know the speed limit in a built up area is 30mph.
More than a quarter failed to correctly identify the no right turn sign. One in seven thought the sign meant the road up ahead on the right was closed.
