By “20”, you’re talking imperial units? Mph?
Yes, 20mph zones on a nationwide basis are a fairly new occurrence here. Wales rolled them out a year or two ago, and they’re being rolled out in Scotland now.
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.
