Generally, instructional signs are a sign of failure – failure to design roads in a way that stimulates sociable conduct. The following sign typifies the futile interventions that characterise traffic (mis)management. Try taking all that in as you drive past!
The road network is an obstacle course where we have to duck, dive and drive on defensive auto-pilot to survive the mean-spirited strictures imposed on us by faceless technocrats. On every journey we face a barrage of instructional signs which interfere with the job of watching the road and getting around safely and expeditiously – yet where are the directional road signs when we need them!?
On the M4 once, we met a cloudburst. Everyone slowed to crawling speed. After a while, the rain eased off, and gradually we picked up speed. Five minutes later, we were doing a perfectly safe 60, when we passed a sign on a gantry that warned: SLOW DOWN. SPRAY! That’s how useful signs are to the needs of the moment.
