DO you know what road signs look like off the top of your head?
These awful sketches reveal the answer is probably "no".
And it's not just a case of bad artists being quizzed as the wrong basic shapes are used by most.
A study by HPI Check asked thousands of Brits to draw common roads signs from memory - and the majority failed.
The drivers had to sketch the sign for a roundabout, national speed limit, the end of a motorway, give way and overtaking.
And 90 per cent couldn't get the roundabout sign correct while 70 per cent failed to draw a give way sign.
Just 15 per cent drew the end of a motorway right and only half could remember a stop sign from memory.
The worrying stats that show drivers need to recap the Highway Code - and quick - were backed up by the same drivers being asked to identify road signs.
A PUZZLING SIGN Are you more street-wise than the average UK driver? How many of these 15 road signs can YOU identify?
The uneven surface sign proved the trickiest with nobody guessing correctly.
While just 1 in 20 could name the no waiting sign.
Fernando Garcia, consumer marketing director at HPI Check, said: "We thought we’d see a bigger improvement in people’s knowledge of road signs when asked to name them, as opposed to draw them, but interestingly results were quite poor for most drivers on both tasks.
"You would expect signs such as the ‘roundabout’ to be easy to draw and recognise but this was actually proven to be one of the most difficult to distinguish, with it being so similar to the sign for a mini roundabout.
“We hope the research might clarify the meaning of these signs for some people, which might make their life easier when they are next out of the road."
