The Conservatives in Wales lose their last ditch attempt to stop the speed limit change from 30mph to 20mph. The change will be coming into force on the 17th September
If the Tory member is going to argue that this will cost £millions to the economy, perhaps he could elucidate us with that evidence.
I am a ROSPA and IAM trained driver, this speed limit change will not hinder progress in built up areas. It will definitely save lives and reduce pollution. In heavier traffic, ruzh hour, it will make not difference.
It's still not the right way to go about it. If you want to make a 20 mph road, then build a 20 mph road - complete with traffic calming measures, as per the official recommendations. Just slapping a 20 sign on a road that feels like a 30 is only going to increase noncompliance (currently measured at ~85% for 20 roads). That's not to mention traffic light systems that have been timed to 30 mph roads, these are never updated when the speed limit changes.
If you want people to change how they drive, then they need training, not altered roads. Hell, even just doing your ROSPA and IAM isn't perfect, because if you don't keep up your training you'll develop bad habits over time.

Big assumption, one that doesn't hold up. Travelling at 20 mph takes 50% longer than travelling at 30 mph.
It will definitely save lives
Possibly, in a select few areas. These areas should be identified and addressed properly, which may well save more lives.
and reduce pollution
The difference in fuel consumption between driving at 20 and 30 is negligible. The main economy difference is acceleration, and slowing down and accelerating for 20 areas increases fuel consumption. Hell, the government white paper on speed bumps mentions higher fuel consumption leading to fuel tax revenue as a benefit.
In heavier traffic, ruzh hour, it will make not difference.
Probably not, but that's not the concern here. The concern is about impeding progression when there is no traffic and no good reason, ie an empty road through town in quiet times with few cars or people about.
I'm sure there are some areas that will benefit from a reduction to 20 limits, but a blanket change from 30 to 20 is just poorly thought out political pandering.

The thing is, nobody plans to crash their car into a pedestrian. So how does it keep happening? One reason is from people driving faster than they should because they wrongly believe a road is empty. Slower limits help with this, because when drivers are going around with incorrect beliefs about whether roads are empty or not, there is more time to react and less energy to cause injury
You can do the maths to work out percentages of a small number. Perhaps check the killed and seriously injured specs, and whilst online, the other technical assessments. Give me more than uninformed view to consider.
But the UK just released that 85% of drivers exceed 20 limits - particularly in roads that were not designed and don't "feel" like 20 mph roads.
These reductions in speed limits are primarily political, while corruptly funneling money to overpriced contractors and police running deceptive speed traps. They serve to give brownie points to the people patting themselves on the back for doing it, meanwhile they do nothing to actually make the road work properly. They'll just slap a new sign on and paint some lines which flow worse than a 6 year old's scribble.
That's completely wrong. Compliance is much better for 30 mph roads, it's pretty much the other way around with 50% exceeding the speed limit but 82% driving less than 35. Meanwhile only 15% of drivers on measured roads follow 20 limits, with 50% of drivers going above 25. Source
It should be noted that the "measured 20 roads" are primarily roads that don't have traffic calming measures, which were designed and built for 30 but have had 20 signs slapped on them - but that's exactly what this proposal is about. When roads are built with the official recommended traffic calming measures, when the roads actually feel like 20 roads, then there's compliance. But that's not what they're doing here.
It still means fewer pedestrians crippled.
That's an issue in specific areas, not in every single part of every single 30 limit.
If you want 20 mph roads, then build 20 mph roads. Provide ongoing training for drivers. Don't just slap a sign up and jerk yourself off over it.
Turns out that after people have been fined a few times, they suddenly do feel that 20mph roads are 20mph roads.
Almost as if they knew the road was 20mph all along, but decided to ignore the clearly marked speed limit (and often the speed limit warning on their satnav) because they hadn't faced any consequences for it before.
I have seen documented evidence many times that enforcement does NOT alter people's behaviour in a way that persists after enforcement ceases. They simply adapt to the enforcement level, whatever that happens to be. I don't think that enforcement is a reasonable component of street safety. We can't have street daddies on every corner keeping us safe.
No, they're not. The limits are assigned so politicians can pat themselves on the back and maybe score some votes. Sometimes also so some new speed trap locations can be created, catching people out in areas where the road feels like it has a higher speed limit (although this is perhaps less true for 20 zones).
If the goal was safety for pedestrians then a hell of a lot more should be done than just messing with the speed limit. Like, actually altering the road and including traffic calming measures - like the official recommendations for 20 limits state - and also providing ongoing training for drivers.
I get your point about drivers exceeding the limit anyway. They trialed the 20mph in our area and on some roads it doesn’t feel like anything has changed.
Hopefully with this put in place first, they can then target areas where people are over and have the legal “backing” to add traffic calming.
I detailed it more in one of my other comments and the government data and graphs can be found here, but yeah the real non-compliance happens when roads are reduced without traffic calming measures. Which basically shows that reducing the speed limit on its own does nothing but criminalise road users.
I doubt that noncompliance can effectively be used to deliver further measures beyond speed limit reductions. Rather, people are going to say "See, your blanket 20 limit doesn't work, you should undo it".
Ultimately I see this as a very cheap but ineffective method at achieving its purported goals, but it's very visual and very cheap so politically it's fantastic.
