The reason why policemen stop and talk to cyclists on fast dual carriageways is because if they didn’t, after observing the cyclist and the cyclist is killed, the policeman would be held negligent of doing his duty.
The incident will be recorded in the officer's report. "The cyclist was advised against riding on the A47".
Is it every policeman’s duty to protect the citizen? Or at least advise on ‘safer’ routes for cyclists. Does the ‘To protect and to serve’ motto apply in the UK?
In a similar manner, an AUK Organiser will advise the riders not to use the A47 dual carriageway. Some newbie Auks will think “I don’t need an AUK Org telling me what for.”
