New High tech cameras to enforce 20mph roads

motorbiking · 22 Mar 2026

You get poor compliance because some idiot installed them on major roads. There were almost certainly some roads where 20mph made sense, but to have them as the new 30mph and enforce them knowing they don’t make sense to 80% of drives is bonkers.

This might explain why some are less bothered than others

Stoke on Trent just 3.2% of urban roads have 20mph, Croydon 81.6%

While not accounting for the entire number, it might be that Croydon has a far greater number of roads that are not suited to cars at all, let alone cars permitted to travel at up to 30mph.

20mph might be the more palatable decision, in comparison with banning vehicles from them altogether.

Take a look on google maps, miles and miles of A roads with 20mph limits on them. A232 for example

Not wishing to argue and not disputing what you said, but your original source said %age of roads, while you're next post said % of miles.

Which are very different metrics.

Only with a number of assumptions being in place.

As with many statistics, more useful for pushing a chosen narrative, than for objectively informing.

for example a "40% reduction in the number of people killed"

Which turned out to be over 24 years and a total of 4.

I think most people would consider that to be statistically irrelevant.

I do absolutely agree with the limits, if I didn't make that clear - on both a safety, and amenity point of view, but without proper enforcement they are pointless...

I didn't mean to suggest your road shouldn't have a 20 limit. Clearly it should, and it should be enforced better.

Speed cameras with no flash or road markings coming to London

Cameras that can detect speeding cars across five lanes will be trialled to help reduce road deaths.

After receiving a speeding ticket, Evan Davis explores why so many people have broken 20mph limits across the country.

These days I avoid driving in London, but there are huge lengths of arterial roads with 20mph limits on. Now even more fines are coming as the new cameras have longer range, no road markings and don't flash.

You might be fooled in to believing TFL's 20 limits have massively reduced the number of people killed or seriously injured. Ignoring the frequent claims that this is so and looking at the data, you will see it hasn't done much of anything to make a difference.

More control. More surveillance. More Big Brother.

The mugs will lap it up.

I got caught speeding a while back

Irony was I was going to the festival of speed

36 /7 in a 30 some mobile plod van

Asked for pic evidence which they sent of the driver told em it was not me which it was not

They made an example of me ?? Got fined nearly 500 squid and 4 points

Total disgrace imo

Significant falls in the number of those killed or seriously injured (20MPH zones) is welcome news.

Do you think less deaths is a bad thing or irrelevant?

The numbers haven't gone up or stayed the same. They've gone down.

20 MPH is here to stay. Expect to see more of it not less.

Why would a road, which is designed to carry vehicles, not be suitable for a car?!

Croydon does have some tight side roads, due to terraced houses with only on street parking, you'd drive down those at 20 just out of common sense.

I drove through Croydon recently, into Clapham via Streatham, 90% on main roads, pretty much 20mph all the way, the majority of drivers were going over 20, not by much, but enough to make the journey slightly less tedious. It still took bloody ages to travel just a few miles.

Perhaps I could have chosen better wording.

How about "not suitable for today's larger cars and heavier traffic densities"?

Especially when what should realistically be for the residents are used as rat runs and cut throughs.
