• We welcome the DfT report on its Atkins evaluation of 20mph limits.

    It provides positive evidence of the benefits of 20mph limits as well as identifying the benefits of better enforcement and national media engagement on 20mph limits.

  • Our 2018 Conference was held in Cardiff

    Our conference looked at 20mph limits from a Welsh perspective including how newly devolved powers could create healthier communities. Read the conference report.

  • Local Authorities could enforce 20mph limits

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 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.

    Lower speed limits save 5x more road casualties than targeted interventions

    A guest blog from Adrian Berendt of 20's Plenty for Kent and Campaigner of the year - 2018 Introduction Road safety professionals often prefer targeting road safety improvements on particularly dangerous roads and junctions? Others consider it better to make more general interventions with a wider impact, known as the ‘prevention paradox’, e.g. health impact of immunisation. We assess which approach is better by comparing two alternative approaches[1]. 1) Targeted interventions on rural A roads. We use the example of the £100m fund for specific interventions as proposed by the UK government; and 2) Prevention Paradox – lowering overall speeds by a few miles per hour with wide area 20mph on urban non-A roads. Our analysis shows that spending the same money on Alternative 2, the “Prevention Paradox” saves 5 times the number of KSIs as targeted rural A road interventions.   [1] We eliminated three other road types as potential candidates: Motorways: few casualties and atypical of the UK road network; Rural non-A roads: extensive, carry little traffic and have few casualties; and Urban A roads: mixed characteristics of each of the road types chosen; might need a combination measures.

    Scotland’s aspiration for more liveable communities via 20mph limits is ideally timed to benefit from new speed limited vehicles

    Recent changes to vehicle specifications applicable from 2022 have ramped up expected returns and effectiveness from the Safer Streets 20mph Scotland Bill being considered by MSPs. Members of the Scottish Parliament (MSPs) have already heard that a national limit is extremely cost-effective. At £10m for 2 years – (only 0.75% of Government transport funds), it pays back in year one. New speed limiting laws make it even more cost beneficial.

    Speed Limiters Mandatory for New Cars: 20mph Self Enforced

    In-car speed limiters stop drivers speeding. Whilst some vehicles have them as an optional extra, the EU plans to make in-car fail safes compulsory on all new vehicles from 2022[1]. Crashes will fall. Though they can be overridden, once widely used, limiters could largely replace education, engineering and enforcement further reducing societal costs. Wide-area 20mph and limiters revolutionise road safety.   [1] https://etsc.eu/meps-back-life-saving-vehicle-safety-standards-in-key-vote/

    20mph Limits Help the Invisibly Disabled Gain Social Equality

    Not all disabilities are clearly visible. Drivers simply can’t tell if someone at a roadside has mental health, sight or hearing issues, or limited physical abilities. 20mph limits are the safe speed wherever people mix with motor traffic. 20mph upholds duty of care and rights in the Equalities Act.

    Women Gain Confidence, Exercise, Time & Freedom From 20mph

    Both genders enjoy a better quality of life in wide area 20mph, with women benefiting most. Calmer speeds lead to greater street confidence, freedom from some child escort duties, a greater ability to exercise safely and more time due to less escort duties.
