A couple of months ago, the Government advice on 20mph zones changed to make it easier (and cheaper) to implement them.
I’d like to have a look at Cheadle & Gatley and see where it would help to have 20mph zones implemented – I’d like your thoughts on what we should do.
How they work
A 20mph zone typically has signs on posts and marks on the road to remind people. It need not have physical traffic calming (e.g. road humps). The police generally don’t enforce 20mph zones, but research and our experience suggests they do reduce speeds significantly.
Where the average speed of traffic is around 30mph, just having a 20mph zone can cut it by 6-7mph. That doesn’t mean everyone drives slowly, of course, but it does seem to genuinely improve the situation.
What should we do?
My feeling is that we should have more 20mph zones. At the moment, the default speed limit along residential streets is 30mph – I’d like to see that default reduced to 20mph and then keep it at 30 only where there’s a good reason to do so.
What do you think? Should we have a broad 20mph limit across most residential streets; or some smaller areas at 20mph, or perhaps the limit should stay at 30mph. Let me know.

20 mph should be imposed on Marrick Avenue, Cheadle, SK8 1QQ. This road is used as a rat run for people trying to beat the queues for Gatley lights, with them getting up to 40mph.
