20mph limit default on street-lit roads in Wales - did it happen?

report page 5 said:
A default 20mph speed limit for restricted roads in Wales should be introduced as quickly as possible, with a target date of April 2023 for the change in the law coming into effect. This is based on a Plenary Vote in the Senedd to take forward the legislation being secured in July 2020 and the passage of the legislation being completed in October 2021.

No, it has not happened yet.

theyve said some things 'could' happen

Reducing the speed limit from 30mph to 20mph in these areas could see a number of benefits, including:

reducing road collisions
more opportunities to walk and cycle in our communities
helping to improve our health and wellbeing
making our streets safer; and
safeguarding the environment for future generations.
safeguarding the environment?

Pollution. Same reason as 50 mph on several trunk roads.

I'd love to see some data on this. I get how 70mph to 60 woukd reduce consumption, as wind resistance squares with speed.
But 20mph vs 30 - arent most csrs designed to be efficient at 30 (50kph) because that's a common speed limit in all of Europe? Will driving round at 20 in 3rd not just be similar to 30 in 4th but it takes you longer to do, so you emit very slightly less for quite a bit longer?


Would love to see some actual testing. They'd have to include the effect of the lower total car throughput of roads at lower speeds, because cars sat motionless idling are the worst mpg / pollution per m there is!

Does that mean EV's can ignore the limit?

Nope. Many of us have asked.

Time isn't a variable in the emissions per unit range. You don't burn more.fuel.just because you were driving at a slower speed for a fixed distance.

There's plenty of actual test evidence out there, it's it hard to find.

Pollution isn't just limited to exhaust pollution. Noise, tyres, brakes...

Trialing 20mph zones in Cardiff and more being added.

50mph will be the max speed soon enough. The Welsh government hate the motorist.

Neither "safeguards the environment" as 30 mph will likely be more fuel efficient than 20mph, just as roughly 55mph will be more fuel efficient than 50 mph for most cars.

I'm in the People's Republic of Richmond upon Thames. 20mph everywhere apart from a couple of 30mph roads and the A316 which is mostly 40mph average speed.

Trouble is the sheep now stick to 18mph everywhere which is enfuriating, especially on empty roads at night.

You see idiots trying to overtake cyclists but as both bike and car are now traveling at similar speeds the overtake, and danger, takes far too long.

It also results in impatient cars doing crazy overtakes of said 18mph cars on narrow residential roads.

I find it odd that in the main drivers are religiously sticking to these ludicrously low limits despite there being currently very few cameras.

Crazy innit.

I wouldn’t mind if the esteemed Mayor practiced what he preached and cycled around like Boris did.

Instead he drives around in a three car convoy with his security detail to take his dog for a walk in Battersea Park.

"Rubbish" that can be proven by calculating the most efficient cruising speed. The anti-car brigade love their 50 mph limits, as it makes motoring more of a grind, just don't justify it on environmental grounds if it prevents cars reaching their most fuel efficient speeds.

The Welsh government like having the power to make decisions,no matter how insane those decisions may be

All of these are desirable benefits.

Why stop at 20mph though? Wouldn’t 10mph be even better against all of the criteria?

The idea of the efficiency of 55 comes from historically quoting three speeds / cycles of which 55 was the most efficient. It’s not a significant number from a physics point of view.
