Frequently Asked Questions

Why does 20mph matter?
Because it is safer, healthier, fairer, greener, quieter and better for people’s quality of life.
How much safer is 20mph?
You are 7 times less likely to die if hit at 20mph than 30mph or 10 times if over 60 years old. 
In the distance a 20mph car can stop, a 30mph car will still be doing 24mph. Far better to just miss than actually hit someone or be hit at any speed.
Are fewer people injured in wide 20mph limits?
Does 20mph always mean humps?
No, we campaign for signs, lines, community engagement and driver education.
What policy do you campaign for?
20mph as a default, wide-area limit for most roads in built up areas.
Where agrees this policy?
Most of the largest 40 local authorities. 15.5m people - 25% of the UK population -
Isn’t 20mph around schools enough?
No - slowing the last 100m doesn’t help children to walk or cycle to school or prevent many casualties (80% of child casualties are on non school trips)

    Do you consider at all if people will be still able to go places and move their goods in reasonable time? Will public transport, lorries and other such vehicles remain functional? If a bus is unable to go over 20, will it be able to keep even 10 mph average speed?

    It’s just been installed in Kibworth Harcourt on the main thoroughfare, but Carlton road no included, how can I change this please? It’s got tiny pavements and lots of dog walkers, plus a 60 mph straight into a 30 currently, it’s a disaster not to have it included, thanks Kathy
