A history of traffic signage
The other day, at the traffic lights, the “No U Turn” sign, with the red line slashed across the bent arrow, caught my eye. It occurred to me that these signs must be standard across the world. Otherwise, in addition to dealing with each country’s traffic idiosyncrasies, one would also have to learn and unlearn traffic signs. This got me wondering when this standardisation came about and what driving a vehicle must have been like before standards were set and implemented.
