Residential speed limit of 20mph to save Wales £100m in first year

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.
