Japan follows Spain, Wales, Greece and Norway in setting a national urban/village default of 30km/h. Road Safety professionals argue for nations to either set 30km/h as a national urban/village default or allow cities/administrations to set it themselves.

etsc.euJapan makes 30 km/h the default speed limit on most residential roads - as European city survey shows significant safety benefitsJapan has lowered the statutory speed limit on most of its residential streets from 60 km/h to 30 km/h, effective 1 September. The new limit applies automatically to roads narrower than 5.5…

What's happening here? Maybe something changed part way through 2023 on urban/residential 30mph roads! I wonder if it could be that from Sep 17th 2023 95% of roads with a 30mph limit were changed to 20mph. #20splenty making your place an even better, safer, quieter, fairer place to be!

The UK Road Safety Strategy adopts a Safe System approach with a target of a 65% reduction in KSIs by 2035. With lower urban/village 20mph implicit within a Safe System culture they will become the norm in the UK. #20splenty is making our places fit for the 21st century.

The number of casualties on those public spaces between buildings that we call roads is a choice. A choice for politicians who create an environment that works for all its citizens or prioritises those in motors. It's why 20mph or 30km/h should be the limit where people are.

It's clear from all the recent data that 25% of urban/village road casualties can be eliminated by correcting one simple human error! That error is maintaining a 30mph limit for most urban/village roads. The Safe System approach will change this to a survivable limit of 20mph.

The 224 cities (including 10 from UK) in the Eurocities network of major European cities have teamed up with ETSC to call for national governments to adopt 30km/h (20mph) as a national norm for urban/village streets. See

When Wales set a 20mph limit for most urban/village roads it made walking and cycling safer. On urban/village roads there were 23.9% fewer pedestrian casualties and 26.5 fewer cyclist casualties. But the largest casualty reduction was for car/van/taxi occupants where casualties reduced by 29.2%.

Analysis of the 1st year after Wales implemented its default 20mph scheme that changed most 30mph roads to 20mph shows an overall 26.2% reduction in casualties on such streets with car, van and taxi occupants showing the largest absolute and %age reduction. Source is Stats19 data

The UK Government has committed to a Road Safety Strategy that adopts a Safe System Approach with a target of reducing KSIs by 65% by 2035. Here is what Transport Professionals are saying about how to incorporate 20mph limits into that strategy

The Welsh national 20mph default speed for urban/village streets has already won the Prince Michael of Kent International Road Safety Award and will be seen as one of the most successful road safety interventions this century. #20splenty pja.co.uk/2026/08/06/r...

For the 5th consecutive year child casualties have flat-lined at around 13,000 road casualties of age 16 and under. In what other area of life would the death or injury of 13,000 children be "acceptable"? The government has a Road Safety Strategy that aims to reduce child KSIs by 70%.

Coupled with a Government target of 60% of children walking or cycling to school by 2035, the Safe System Approach with its implicit adoption of survivable limits on urban/village streets of 20mph will be mandatory if both targets are to be achieved.

Evidence shows that setting 20mph as an urban/village norm reduces casualties by 25% and this has to be the future direction of setting speed limits England. Note that Wales and Scotland have already done so.

Its why it is so important that the UK now has a Road Safety Strategy based on the Safe System Approach and it's requirement that national and local authorities set "survivable speed limits". The strategy also targets a 70% reduction in child KSIs by 2035.

Within community streets where people walking and cycling mix with motors in a planned and frequent manner then that is 20mph as a default with a higher limit only where evidentially safe. When Wales set a 20mph urban/village default it reduced casualties on lower speed roads (20mph/30mph) by 26%.

UN members (except USA) have committed to setting speed limits based on human tolerance to injury (survivable speed limit) in its Progress Declaration. This aligns with the UK adoption of a Safe System Approach in its Road Safety Strategy. For urban/village streets that norm is 20mph

Lives Saved - This is my motion to parliament marking 10 years since the 20mph rollout began in Edinburgh. BBC coverage from July 2016: www.bbc.co.uk/news/uk-scot... @edinreporter.bsky.social @edinburghminute.com @spokes.org.uk @livingstreetsedi.bsky.social

Good to see the DM being asked a question and getting experts to answer it. The report concluded that the additional energy required for the engine to repeatedly accelerate up to a 30mph speed limit in stop–start driving means 20mph zones are generally more fuel–efficient.

dailymail.comDoes my car use more fuel at 20mph than at 30mph?I live in North London, where roads now have a 20mph limit - and I'm convinced that I'm filling up with fuel more often.

In 2013 the UK Gov guidance on setting 20mph encouraged doing so on main roads. As progressive authorities across UK did so, it has built the evidence that 20mph main roads with previous higher speeds and pedestrian interactions record greater speed reductions and 25% casualty reductions. #20splenty

We asked Gemini a couple of simple questions starting with: "𝗖𝗮𝗻 𝘁𝗵𝗲 𝗨𝗞 𝗴𝗼𝘃𝗲𝗿𝗻𝗺𝗲𝗻𝘁 𝗺𝗲𝗲𝘁 𝗶𝘁𝘀 𝗿𝗼𝗮𝗱 𝘀𝗮𝗳𝗲𝘁𝘆 𝘀𝘁𝗿𝗮𝘁𝗲𝗴𝘆 𝘁𝗮𝗿𝗴𝗲𝘁𝘀 𝗮𝗻𝗱 𝗸𝗲𝗲𝗽 𝟯𝟬𝗺𝗽𝗵 𝗮𝘀 𝗮𝗻 𝘂𝗿𝗯𝗮𝗻 𝗻𝗼𝗿𝗺?" The answer was very clear.

The Government in its Road Safety Strategy commits to reduce child road casualties by 70% by 2035. It also wants 60% of children walking or cycling to school by 2035. These won't be achieved if 30mph is kept as an urban/village norm. Our comment details why and how to deliver #20splenty nationally.
