20mph speed limit ‘could save Wales £100 million in first year’
The new 20mph default speed limit in Wales could save £100m in its first year as deaths and injuries are reduced, according to new research. The Welsh Government will introduce a default 20mph speed limit on restricted roads across Wales in September 2023. Restricted roads include those with street lights and are usually located in residential and built up areas with high pedestrian activity.
The new research, conducted by the Transport Research Institute (TRI) at Edinburgh Napier University, in conjunction with Public Health Wales, estimates the default 20mph speed limit will save around £100 million in the first year alone. The estimated cost saving is the direct result of fewer deaths and injuries – with predictions that the lower limit will save more than 100 lives over a decade and 14,000 casualties in total could be avoided.
Lee Waters, deputy minister for climate change, said: “The evidence from around the world is very clear – reducing speed limits reduces collisions and saves lives.
“Slower speeds also create a safer and more welcoming environment, giving people the confidence to walk and cycle more, which will help to improve our health and wellbeing and help to improve the environment. This new research shows the savings in terms of reductions in people being hurt or killed but the benefits of 20mph stretch much further than casualty savings alone. The report suggests the lower speed limit will help encourage physical activity and in turn reduce obesity, stress and anxiety.”
