There is only one "blanket 20mph limit" local authority in the whole of the UK and its in the City of Westminster covering all their roads, including the 'A' road outside Houses of Parliament. Put there by Conservatives to protect MP and government staff.

Of course 20mph seems slow to drivers. That's the whole point. And it also seems slower, calmer, cleaner, safer and quieter for all the people who are not in cars and living their lives in communities. It's why

You hear it all the time "it's not natural to drive at 20mph". So please will someone explain what is "natural" about wrapping yourself in a metal and plastic vehicle weighing 1 to 2 tons in order to drive 1 mile to get a newspaper or for your child to get to school?

Driving at 30mph instead of 20mph in an urban environment doubles the fuel and energy required every time you stop and then go back to speed limit, reduces a driver's field of vision, doubles the braking distance, doubles the noise and reduces your journey time by seconds.

If that Land Rover had been sold in EU27 it would have had Intelligent Speed Assistance limiting the speed to the limit of 20mph. The mandatory fitment of ISA which UK gov campaigned for when in EU was dropped by UK gov for cars sold in UK. This is one of the consequences.

Its a game-changer for enforcement. Speedcam Anywhere can be discretely and safely used with any smartphone by pedestrians similarly to drivers using dashcams. Evidence of driving above the speed limit can be uploaded to police dashcam portals.

20mph limits can actually shorten journey times. New research from Prof Dr Niels Benedikter at the University of Milan confirms 30 km/h (18.5 mph) as the optimal speed limit for minimising delays through traffic congestion.

Ignore all the noise about cyclists and 20mph limits. The real story is that yesterday Edinburgh reported that reducing the speed limit for motors to 20mph over the last 3 years reduced crashes and casualties by 30% saving £38m. See

Its simple. Every time you accelerate to 20mph you require energy proportional to speed squared. Carrying on accelerating to 30mph requires 1.25 times additional energy. Its why in "real-world" urban conditions 20mph limits reduce fuel and pollution.

Driving at 30mph instead of 20mph in an urban environment
1. Doubles the fuel/energy required every time you stop and then go back to 30mph
2. Reduces driver's field of vision
3. Nearly doubles braking distance
4. Doubles the noise
5. Reduces your journey time by seconds.

People tell me their cars aren't designed to be driven at 20mph. In Germany they have had 30kmh limits for 30 years so BMWs, VWs, Mercedes and Audis can therefore be driven at 18.5mph instead.
28
53
291
Things that are always the case when wide-area 20mph limits are set:
1. A small number of people will noisily object.
2. Speeds will reduce.
3. Casualties will reduce.
4. Most journey times are minimally effected.
5. Communities never set the limit back to 30mph.

Rishi's got it wrong. The demand for 20mph limits where people live, play, work, shop and learn will keep on growing. There will be noisy opposers who don't care about walking, cycling, elderly, children, quieter streets, civic society and fairness. He is welcome to them

Just to clarify. In UK, all ebikes are limited so that they do not assist above 15.5mph. Any electric 2 wheelers which do power above 15.5mph are electric motor bikes and have to be taxed and insured, riders to wear helmets and as "motor vehicles" comply with speed limits.

All over the world 20mph and 30km/h limits are being set as the norm in villages, towns and cities. It's not fascist or communist, or even right or left, but is a simple and cost-effective way to make places better places, especially for the most vulnerable road users

When the seat-belt law was introduced there were many who opposed it. Indeed even today there are individuals that think a video-clip to supporters is worth breaking the law. Just like seat-belts, 20mph limits protect life and the load on the NHS.

Of course some drivers will object to a 20mph limit as a norm through towns and villages where roads are shared with people walking and cycling. That's why speed limits are set by society rather than left to individuals. Well done Wales for setting a national 20mph default.

Good news! Driving at 20mph in urban areas doesn't just reduce road danger. Less acceleration also helps save 10p p/mile (30%) in urban fuel costs. Save money, save fuel & reduce emissions for negligibly different journey times compared to 30mph

There are 30km/h (18.5) limits as a norm in villages and towns all over Europe. Yes, even in the land of BMW, Audi, Merc and Porsche where their designers live. The idea that " my car wasn't designed for 20mph" is absolute nonsense.

Great to see that in just 20hrs Wales will get a 20mph limit as a norm in cities, towns and villages. So aligning itself with countries like Spain, Switzerland, Netherlands, Norway, Belgium, Luxembourg, Sweden and Denmark which have a similar norm.

On 30mph residential streets parents won't let their children use the roads because the cars drive too fast.

Dear English people. Please don't believe some people saying Wales has a "blanket" 20mph speed limit. Only built-up roads are affected and many have 30mph and 40mph limits. 20mph makes Wales an even better place to visit with calmer, quieter and safer villages and towns.

Far more fuel is used accelerating to speed limit than steady driving. So minor differences between steady 20 and steady 30 are trivial. As it requires 2.25 x the energy to reach 30 compared to 20mph then reducing limit will help emissions in real-world urban driving.

Just drove across mid-Wales from Shrewsbury to Pwllheli via Weshpool. I drove on fewer 20mph limits than 30mph. Noticed all limits being complied with especially 20mph and those roads were so much calmer for drivers and more pleasant for walkers and cyclists. Well done Wales.
58
13
206
Remember that every time you accelerate to 30mph you more than double the energy required to get to 20mph. With real-world stops for junctions, crossing, lights, obstructions and hazards its why a 20mph limit reduces fuel consumption and emissions in built-up areas.
54
73

What always strikes me on social media is that if anti-20mph people drive with the same courtesy that they display when posting or commenting on X and Facebook, then it's ample evidence of why 20mph limits are needed.

The key factor is not what a protected, safe and in-control driver thinks of the difference between 20mph and 30mph but how a child walking to school or elderly to the shops, thinks and feels about the safety it brings.

The idea that adding 60 seconds to journey times in Wales will "harm the economy" is bunkum. Its like saying having a coffee, or looking in a shop window, or stopping to admire a view for a minute would "cost the economy". We explain why in our FAQ

178
THE DEFAULT 20MPH LIMIT FOR BUILT-UP ROADS IN WALES IS STAYING.
There are no plans to change it. The new updated guidance, just like previous guidance, allows authorities to except individual roads using a TRO if evidentially justified.
28
43
182
On most A roads through communities setting a 20mph limit would not increase journey times which are determined by too many cars rather than too little speed. Hence a 20mph limit increases safety, decreases noise and pollution, and makes those places more liveable.
6
73
177
Due to the default 20mph in Wales for residential areas
:
500,000 Welsh children find it easier and safer to walk or cycle to school
300,000 Welsh families who don't have access to a car have more equitable mobility
600,000 Welsh families with travel cards find waiting for a bus
40
56
175
When you accelerate a car to 30mph you use over twice as much energy as that required to accelerate to 20mph. It's why urban fuel economy is lower than open-road fuel economy. Its why cutting max urban/village speeds to 20mph will actually save fuel
78

Lots of stuff on twitter about needing 20mph "only round schools", but children need 20mph on their whole route walking or cycling to school. At any time there are far more children outside "outside school" than than "outside school". Its why 20mph is best for communities.

The idea that 20mph limits are only required outside schools is flawed. Children need 20mph on their whole route from home to school. So does anyone walking to or near shops. The need doesn't disappear on main roads because you find 20mph "annoying"

20mph and 30kmh limits have existed for 30 years across the whole of Europe (and I include UK in that). The idea that cars are not "designed" for the 20mph or 30km/h limit set to protect vulnerable road users in communities is simply not credible.

Of course some people don't like driving at less than 30mph on roads within communities. That's why 20mph limits are set to make living in them more pleasant for residents and making them better places to be 24/7 for people walking, cycling, chatting, shopping or sleeping.

It's good to see a tourist guide on Road Trip Wales taking a rational view of the default 20mph limit. It adds just 9 minutes to their 7 day itinerary.
60
32
161
For most cars driving at 20mph requires no more RPM than at 30mph, but uses a lighter throttle. Hence steady-state mpg is similar. In repeated acceleration to limit energy required to 20mph is less than half that for 30mph. Slower is calmer, quieter, safer and cleaner.

Lot's of talk of "war on motorist" from those who should know better. See the detail on what kills most on the roads and you find its motor vehicles. Protecting vulnerable road users by lower speed limits isn't "war". Ask anyone from a real war zone.

Currently 30 million people in UK live in authorities that have rejected a 30mph default as not-fit-for purpose and have set 20mph for most urban/village roads. It's time to accept that the 30mph national default is no longer national and simply a legacy from olden days.
