A subversive artist has been raising a few brows among commuters, by drawing a quirky road sign that tells them to 'hang in there'.

The red triangle, complete with image of a rock climber, appeared on the westbound carriageway of the A47 on the Norwich side of the Brundall roundabout.

Motorist Daisy Kingham, who captured this photograph of the sign, said: 'I saw it on my way to work this morning, and thought it was so brilliant that I stopped in a lay-by on the way back, crossed, safely, at the pedestrian crossing gap and took a pic.'
