The Ultra Low Emission Zone (ULEZ) is an area in London, England, where an emissions standard based charge is applied to non-compliant road vehicles
10 million people are now breathing cleaner air, fewer children are growing up with stunted lungs and fewer people will have to suffer from asthma, dementia and heart disease
20 mph is very slow. What kind of zones are we talking about? Surely not stretches of country ways? More like zones inside cities, right? We have a lot of roads in my town/country with a 40 km/h limit. 😁
The national speed limit in the UK is 60mph for all roads - town or county - that aren’t subject to a posted speed limit.
Up until recently, most urban environments with pedestrian access generally fell into 30mph zones, with some side streets and housing estates having their own 20mph limits.
Now, a national template for 20mph for urban areas is being introduced - generally where there’s a lot of housing; retail; schools etc or in the middle of villages or town centres etc.
