What does a 'no bicycles' sign signify?

Answer: C — Bicycles are not allowed in that area or road

A 'no bicycles' sign signifies that bicycles are not permitted in that specific area or road. This means that cyclists must find an alternative route and cannot operate their bicycles on the designated roadway. Such signage is often placed in areas where the road conditions may not safely accommodate bicycles, or where their presence could pose a hazard to both cyclists and other road users, such as heavy traffic areas or certain pedestrian zones. The intention behind this regulation is to enhance safety for all individuals using the roadway and to ensure that bicycles are used in appropriate locations where they can be safely operated.
