You are cycling towards a town centre and see this sign: a red circular sign with a black bicycle symbol inside and a red diagonal line through it, mounted beside a paved area used by pedestrians. What does this sign mean you MUST do?

Explanation

A red circular sign with a bicycle symbol and a red diagonal line indicates that cycling is prohibited in that area. Under Rule 64 of the Highway Code, you MUST NOT cycle on a pavement that is for pedestrians only. When you see this restriction sign beside a pedestrian pavement, you must not ride there: you should dismount and walk your cycle on the pavement, or use the road or a designated cycle facility instead. Riding on a pedestrian-only pavement remains illegal even if you go slowly or warn pedestrians with a bell.
