20mph As Scotland’s National Limit
People want 20mph streets. Fortunately 20mph limits are affordable and do-able. What’s the best method? The Scottish Government can lead with a 20mph default for built up areas. This is a cost effective win-win all round – eg for the legal process, consultation, signage, engagement, higher compliance and enforcement.

Rod King commented on Cheshire East Council to spend £1m telling drivers its not mandatory to go slower around schools and on community streets 2016-01-31 14:40:25 +0000Peter
Thanks for you further comment. WE don’t actually campaign for all urban roads to have a 20mph limit. We campaign that there should be a 20mph default and that any exceptions should be justified. Hence roads which have excellent segregated facilities for walking and cycling, good treatments at intersettions and crossing would not be difficult to justify.
Of course “the child you see” is not so much a problem. Often it is the “child you don’t see” that gets killed or injured, or at least frightened. And of course children with a fear of the roads end up having no independent mobility.
I am not aware of any places in the UK where 20mph limits are being used excessivley, but do recognise that some drivers may feel different. Perhaps it is these drivers that are the reasons why those limits are mandatory rather than advisory.
Advisory 20mph were allowed in Scotland from 2002, but their experience has led Transport Scotland to say that advisory limits should no longer be used and mandatory limits set instead.

2015 - The Tipping Point Year for 20's Plenty
At this time of the year it is traditional to take stock of achievements and progress in the preceding year. For 20’s Plenty for Us then perhaps 2015 will be seen as the “tipping point” when the whole campaign took on new dimensions and success. It does not mean that in 2015 we achieved our aims of delivering a 20mph limit as the norm for all residential streets in the UK, but was the year when we started to see that that aim was going to be deliverable in the foreseeable future.

20mph Council Myth Buster
Whilst many urban councils have pressed ahead with 20mph limits, some County and, particularly Shire Councils have not always told the truth if reluctant to implement 20mph. We bust the common 20mph myths.

I am sure that other readers can make up their own minds regarding “progress and dogma”.

Rod King commented on Campaign 2018-06-17 11:22:53 +0100Hi Jane
I think that you will find the parking charge issue will come and go. But unless people campaign for lower speed limits then it is unlikely that the consensus change about how we drive in the presence of people will ever change. Waiting for some sort of technical solution will take some time and needs that consensus change.
Across the country and county campaigns are making a difference and making the strong support for lower speed limits visible to councillors so that they can set the correct speed limits. We will contact you to see how we can help further and also link up with other campaigns in the area, including the Kent wide campaign.
Best wishes

Rod King commented on Important new wins for 20mph speed limits in London 2015-10-07 21:36:53 +0100Martyn
Thank you for your comment. However, I would suggest that if you drove 14 miles across London, then unless you were taking all residential roads then very little of it would have been on roads with 20mph limits. I would further suggest that your average speed was not due to the speed limit but due to the number of cars on the roads. You will find data on our site which shows that 20mph limits actually reduce emissions from diesel cars.
The comment about speed bumps increasing emissions is only where people illegally speed between the bumps. It is acceleration which causes most emissions, plus brake and tyre emissions from braking. Hence this is not a factor in the wide-area 20mph limits without speed bumps that we campaign for.

We can do that. Note that current DfT guidance states quite clearly that arterial and main roads can be set with 20mph limits. What we say is that any speed limit above 20mph should be justifiable and take full account of the needs of vulnerable road users. Local officers, councillors and communities are best placed to decide such exceptions and inclusions.

20’s Plenty - The Foundation for Active Travel
Being active is the ‘wonder drug’ that more Britons should be taking regularly. The greatest gains in health are from regular activities like walking or cycling locally. 20mph speed limits are a crucial platform for people to choose active travel. All local transport methods and journeys become safer and more pleasant. 20mph helps keep people safe and gets their legs moving more often!

Campaigners - Get 20mph on Group Meetings/Agendas
Successful ways to campaign for 20mph limits include demonstrating community support to local politicians. Getting on the agenda of each major Party political group meeting can really help councillors to understand and vote for a Total 20mph policy. Win by speaking direct to those with power to set local road speeds
