Already over 15m people live in local authorities which are adopting or have adopted this policy. Most importantly, through democratic debate those communities have decided that "20's Plenty Where People Live". And it is those same communities who have then changed their behaviour to drive slower in residential streets and where people walk and cycle.

20's Plenty for Us is a 'not for profit' organisation and now have nearly 400 local campaigns around the country and many of our most iconic cities in the UK have already adopted a 20mph limit for most of their streets.

We quite simply campaign for 20mph to become the default speed limit on residential and urban streets. This can be done on most streets without the need for any physical calming and we accept that on some streets it may be appropriate to have a higher limit based on the road, vulnerable road users provision, etc. But any limit above 20mph should be a considered decision based on local circumstances.

If you are viewing this page then you have found our new website with which we will be building a resource for campaigners and people implementing 20mph limits as well. And it's here that you can set up an account and sign in to get updates, etc. You can sign in with your Facebook, Twitter or Email.

    The "Criminalising" and "bringing the law into disrepute" myths busted

    Another question we have had put to us is :- “In moving from 30mph to 20mph without adequate physical changes and/or enforcement, we are criminalising a higher percentage of people and that brings the law into disrepute”. * Laws change or are revised because of a change in public consensus. We know that over 70% of the population support 20mph limits without traffic calming in residential streets – British Social Attitudes Surveys tell us so – see https://travelwest.info/project/ee-113-city-wide-residential-streets-20mph-speed-limits.  Support for 20mph has remained this high for a decade. * Any time a law is revised/updated there is a period of transition. This is so whether it is changing a 30mph road to a 20mph road, seat belt wearing, smoking in a car with children, hitting children, hand held mobile phone use when driving etc. Acts which were not criminal before become criminal and people have to adjust their behaviour to the new norm. * 51% of drivers aren’t compliant with 30mph * at 20mph limit the non compliers (speeders) aren’t imposing as much danger on the rest of society as when not compliant at 30mph. * advertising the change to drivers (engagement activities to enhance compliance) in advance of the change and for some time after the change is highly recommended to make drivers aware of lower limits and to reduce the transition period length and thereby improve compliance levels. * It is likely that the same drivers who speed in a 30mph limit will deliberately speed in a 20mph limits. There are probably very few extra people deciding to speed (engage in deliberately criminal  driving). * There aren’t that many drivers who are unaware of the change in limit to 20mph if the limit is signed well enough and wide enough. So there are few people who can claim “I didn’t know it was 20mph” * if other laws were not being enforced we would not say the law was wrong. We’d blame lack of enforcement! * Lack of enforcement and engagement brings the law enforcers into disrepute not the laws. 20mph doesn’t criminalise more drivers or bring the law into disrepute if the limit is enforced. Drivers are less likely to speed if the police support the 20mph policy publicly and routinely enforce it. In summary There are no extra drivers speeding There is a strong separation between elected representatives who set laws based on public consensus and the police for who enforce them and the independent judiciary who sentences.

    The "civil liability" myth busted

    Yesterday I heard from one of our local campaigns about an argument put by a councillor. It was :- "If I designate a street as 20mph, then more people will think it safe to walk and cycle.  I am worried that if someone is then killed or seriously injured by a car travelling at (say) 30mph, then the Traffic Authority might be liable".   Here we discuss the relevant civil case law regarding the duty of the council to act reasonably when managing the roads. The argument condenses down to clear opinion that :- If a Traffic Authority sets a speed limit which misrepresents the hazards involved, then it is in breach of its common law duty of care towards both the driver and to anyone injured. Regardless of whether the road user was negligent, the Traffic Authority risks liability for any consequences. Where a Traffic Authority has set a 20mph speed limit, then liability for any consequences of a collision rests solely with the driver if they negligently exceeded the speed limit and could have avoided the collision if they had adhered to the limit. The argument that Traffic Authorities risk liability if a 20mph limit is set and not adhered to by a driver has no credibility. Instead the reverse is true: The correct setting of a 20mph limit shifts liability to the driver when acting negligently by exceeding the speed limit regardless of any negligence by a vulnerable road user. The Duty of Care responsibilities of a Traffic Authority are further explored in a comprehensive briefing.

    UK needs a new "national" speed limit

    Far from having a “national” urban speed limit of 30mph, this has been rejected by local authorities for a quarter of the UK population.  All but two Inner London Boroughs and over half of the UK’s largest urban authorities now have a 20mph limit for most roads. Rather than just “recommending” 20mph limits the government should set a national 20mph limit and permit local authorities to justify any higher limits.

    20's Plenty for London - Nov 17 Update

    London is making excellent progress in adopting wide-area 20mph limits across its many boroughs. Already 43% of all Londoners are living on 20mph roads and streets with a 20mph speed limit (3.7 million out of a total population of 8.7 million). In the Inner London boroughs more than three-quarters (76%) of the population is living on 20mph streets and roads (2.3m out of a 3.1m population).
