Eight out of ten drivers ignore 20mph speed limit, claims report

By Adam Phillips
News entry dated 12th Jul 2017

Department for Transport (DfT) data has shown that 80% of drivers are turning a blind eye to the 20mph speed limit. According to official figures, the majority of these motorists are travelling at 21-25mph, with 15% exceeding 30mph and 1% clocked at over 40mph.
 

 
The DfT’s data was sourced from nine 20mph areas featuring free-flow conditions and no traffic-calming measures. This is not typical of many 20mph-limited areas across the country. Still, the figures make for sobering reading, especially when compared to road charity Brake’s recent poll, which stated only 52% of drivers were breaking the 20mph limit.

Testing ‘the limit’ of drivers

The often controversial speed limit was introduced in 1991, with 250 areas included across UK roads by the end of decade. In 1999, local highway authorities were allowed to roll out the 20mph limit without needing to apply for permission from central government, which saw an explosion of the limit in many cities and towns. Most recently, some authorities have set 20mph as the standard limit for residential streets, including in Warrington, Hackney and Oxford.

It’s this seemingly indiscriminate approach to 20mph deployment that some motoring groups believe may be causing the problem. The RAC Foundation’s Edmund King explained to The Times newspaper:

“These statistics indicate that blanket 20mph speed limits aren’t particularly effective. Where they are targeted, like outside schools these lower limits work because people can see the point of them. But if 20mph limits are simply imposed over a whole area, people just don’t believe in them and it’s no surprise they then fail to comply.”

The wrong end of the stick?

Others though argue that the goal of the limit isn’t to get motorists driving under 20mph. The AA’s Luke Bosdet told the Daily Telegraph,

“The target is to get people driving below 30mph in these areas. That’s what the 20mph limit is clearly for, and in that sense as far as we’re concerned it’s working.”

He does concede though that how the 20mph limit is rolled out can create issues, arguing that “the problem is a knee-jerk reaction to have these zones everywhere. If local residents want them, they should get them, but the big question is whether they are being consulted. If they’re not being consulted you’re not going to get adherence.”

Adherence is not only a problem for residents or motorists, but law enforcement as well. For instance, in Brighton and Hove the local authority introduced a far-reaching 20mph limit in many areas of the city in 2013. However, Sussex Police went on the record stating that it would not allocate any extra resources to tracking down offending drivers, instead believing that “it’s important that roads are carefully designed to ensure that drivers habitually self-enforce when it comes to speed limits.”

Exception, not the rule

The Sussex Police are the exception to the rule; motorists should expect 20mph limits to remain in place and be enforced. Even after its own startling findings, the DfT still backs the widespread use of the limit:

“Research shows that 20mph zones in the right areas can save lives and we have made it easier for councils to introduce them. It is for councils to set speed limits in their area and police to decide how best to enforce them.”

Are 20 mph limits essential to the safety of our busy streets? Or are local authorities simply rolling them out to boost their budgets through fines? Let us know your views below.

Why am I required to drive past a school at midnight in August at 20mph? There has to be no reason for this apart from someone in an office thinking that people only go past schools between 08:30 and 03:30 during term time. Anyhow, so many parent park haphazardly outside schools at opening, closing and lunchtimes that getting past is a problem, never mind 20mph. Some local authorities have got an idea – a sign with the school patrol flashing lights which says “20mph when light flash”; what is the problem with this? As for blanket 20mph on all residential… Read more »

Well my town piloted this scheme on two roads that were by there very nature already slow because of potholes and parked cars. A HUGE sucess was declared and the perpetrator for the scheme “Twenty is plenty” Rod King of Lymm was given and MBE The rest of the town now has 20 mph limits everywhere and all are ignored it seems. The total cost was at the last count £750,000 of taxpayers money. An absolute disgrace if you multiply the £ millions wasted all over the country. Most of the people I observe must have got the wrong message… Read more »

Where I live the council invited the residents to vote for the introduction of the 20mph limit. Only 2% bothered to vote and of those just over half voted for the new limit. Hardly a resounding endorsement of the policy. Now we have the limit imposed across the London Borough of Croydon willy-nilly. It is frankly pointless as the narrowness of the roads caused by parking renders any attempt to drive faster hair-raising. This seems to be using a sledgehammer to crack a nut. And at the expense of council tax payers : so every few yards repeater signs have… Read more »

It’s a great way for councillors being seen to be doing something. High visibility politicing. That’s why new laws should be subject to the full round of legislative consultation & review whereever they are applied.

I’d like to add that the most ridiculous 20mph speed zone I have encountered was a smart motorway at 2am because of roadworks. The road was completely empty and there wasn’t a worker in sight. I don’t disabey speed limits because it’s just not worth it – losing a week’s earnings as a self-employed courier would ruin me but it sure annoys me greatly when I’m forced to keep to non-sensical speed limits. If I added up the time I’ve needlessly lost due to arbitrary low speed limits I’d probably be astounded. Don’t get me wrong, I think many speed… Read more »

I agree that drivers are more likely to observe the speed limit when it’s purpose is clear. If I approach a school and can see lots of children about (usually at school start and finish times and at lunch time) I slow down anyway, often much below the speed limit. However, at other times, such as in the middle of the night, it seems pointless and it is more difficult to police my speed. Such zones need to be time controlled, operating at certain times, or as I have sometimes seen, only in effect when lights are flashing. The other… Read more »

Mr Digweed, speed does not kill ppl. Otherwise we’d all be doing 20 mph on motorways now wouldn’t we!

If oomph speed limits were policed (but never aere) then more people would obey them Has anyone ever been prosecuted for breaking the 20mph limit I have heard of no one The local authority creates them for road safety reasons but never has them policed A waste of money in creating them if they are never going to be policed
Let’s waste more of the taxpayer’s money is the attitude of all local government authorities in all they do

Laws that are roundly ignored by those they are directed at are bad laws and should be repealed. This 20mph b;anket limit is one such law and is contra-indicated/
Much the same could be said of speed limits in general, but I don’t think I would win that battle!.
The bigger issue is for people to realise that cars CAN kill and should be treated with respect – don’t amble across roads glued to your cellphone, etc.
If people were to treast roads in the same way as rivers and/railway lines, crossing only at specific, safe points, the issue wouold disappear…..

I find the application of 20 mph zones in my City are bonkers. Instead of having consistent zoning we have areas where the central stretch of a road is 20 mph but the entry and exit speeds are 30 mph. So you enter a road at 30 and encounter the need to reduce speed as well as watch out for pedestrians (adult or child) walking out in front of you as well as any issues with vehicles in front or behind you. On exiting the 20 mph restriction you can increase speed to 30 only to brake almost immediately as… Read more »

I find the opening lines of this article very misleading. “80% of drivers are turning a blind eye to the 20mph speed limit”, it begins. And then follows up with “…the majority of these motorists are travelling at 21-25mph”. So they are not ignoring the limit then – they are, indeed, reducing their speed because they have taken notice of it. And no, I am not splitting hairs. I accept the general principle that cars travelling more slowly have more time to avoid accidents and, if a collision does occur, less damage is likely to result. But I do not… Read more »

There are too many differant speed limits now, it used to be 30mph in town,60mph on rural roads & 70mph on motorways, i took a safe driver course run by our local police force & was told/taught to drive to the conditions & this is, i feel the correct way to drive 30mph for instance on a icy road can be too fast or 60mph in heavy rain etc.so drive to the conditions BUT there are too many drivers who do not have a clue how to drive safely or to the conditions & rather than add more restrictions it… Read more »

I wonder why the 20 mph limit has been given special mention.

Many times every day I see cars speeding and breaking the limits.

There seems to be no interest or maybe resources to contain the menace of speeding anywhere

Outside schools or similar busy areas but they are pure stupidity on ordinary roads. When modern brakes and tyres are far superior now the stopping distances in the highway code don’t relate. For example at 30 mph you can stop in about 12 feet – nothing like the 75 yards of the cars when the Code was written. The old brakes were rubbish, in some cases if they even worked at all or didn’t blow the pipes or seals! It’s also impossible to drive so slow and watch both the road and speedometer as you are likely to drive into… Read more »

I use my cruise control to stick to those annoying speed limits. Somehow it seems to ease the pain 🙂

Speedmeters have a accurate of 20%,that it way I drive with my Sat Nav on witch I believe gives a true speed.

True and 20% error on a reading of 20mph could be 16mph. No wonder we’re being overtaken by pushbikes and joggers. It’s absolute lunacy on most roads to impose a blanket 20mph.

Near where I live there is a primary school with a 20mph limit when the children are going and coming from school. Except it doesn’t work. The lights flash if you are above 20mph when the children are in school or when they are on holiday. The lights flash to slow you down but the limit sign with the speed showing says Thank You even when going over 20.

Edinburgh is in the middle of rolling out an almost universal 20mph limit across the city including at least 90% of all road, so most bus route and major arterial routes are included, which is just bonkers! For an impoverished council which is cutting important to spend £millions on this scam is actually criminal. It is interesting that the comment from the AA spokesperson said that the real aim was to get people driving at less than 30, i.e they accept that 20 is too low, but of course ignoring it makes criminal of us all. The crime rate rockets,… Read more »

I think that you have just proved/re-inforced my point, Paul; it isn’t what people want, else they would comply without the need for “Safety” (i.e. Greed) cameras.

This does not surprise me one bit, most people break all speed limits, not just the 20mph limit!

FOR THE THIRD TIME, by convention, THE FULL INSTRUMENT SCALE is used for to determine the uncertainty, so your calculations are incorrect. In my calculations 100mph is assumed to be full scale.

O.L. Grainger
O.L. Grainger

10% of 20 MPH is 2 MPH. So, the margin would be 2 MPH either side of 20 MPH, ie 18 MPH to 22 MPH

Charles Beasley
Charles Beasley

I believe that instrument accuracies are generally quoted as a percentage of the full scale; as a consequence the uncertainty at the lower end is much greater. In my previous post, the value of 20% would give the values as stated; for 10% an indication of 30mph could be between 25 – 35 mph and an indication of 20mph could be 15 – 25mph.

O.L. Grainger
O.L. Grainger

No; 10% of 20 MPH is 2 MPH. So, the margin would be 2 MPH either side of 20 MPH, ie 18 MPH to 22 MPH

O.L. Grainger

Sorry, I was WRONG (I can not type!).

Speedometers should be accurate to within 10% – NOT 20%.- and should register within that range when the vehicle is travelling at more than 10 MPH.

That is 10% – not 10 MPH. So, at 20 MPH, I believe that the speedo. should show between 18 MPH and 22 MPH.

You can always compare the car’s speedo with those given by some sat. navs., including Waze (which free on smartphones.

Charles Beasley
Charles Beasley

If that is 20% of full scale, then an indication of 30mph could be between 20 – 40 mph and an indication of 20mph could be 10 – 30mph.

O.L. Grainger
O.L. Grainger

Speedometers only have to be accurate to within 20%.

Southwark has rolled out 20mph in every street. I see the value in the side streets where space is tight & there may be children around but it isn’t justified on the main roads i.e Lordship Lane & Sydenham Hill. What may be a better solution is to have periods of reduced speed e.g. school opening & closing & market hours on a Saturday

I agree introduction of 20 MPH limits in appropriate areas such as school zones is a good idea. However the blanket introduction of the limit here there and everywhere is just not safe. On a major road where there is no traffic and the road is wide enough its just a fund raising avenue for the council, and a cause of frustration for drivers which makes them less of a safe driver. Also in smaller roads such as residential roads where cars are parked on both sides, especially if the road is on an incline then you have to pay… Read more »

How much money was wasted investigating drivers who ignore the 20 mph speed limit? I assume it was tax payers money?

What would be more sensible would be to carry out the same exercise on motor ways. If I drive at the speed limit on motor ways rarely do I overtake an Audi, BMW or Mercedes. Additionally, how often do I see a police car?

How accurate are vehicle speedometers below 30mph? It used to be the case that there was no accuracy specification below that speed.
