Rule change, a UK first, will save more than 100 lives over a decade, research claims
Setting the default speed limit at 20mph in residential roads in Wales will save £100m in the first year alone as deaths and injuries are reduced, according to research.
The move, a first in the UK, will save more than 100 lives over a decade, the research claims, though a second study has found many people are concerned the limit will be very difficult to enforce and do not believe drivers will respect it.
