Road speeds in cities should be cut to 10mph to prevent deaths and reduce serious injuries, a leading road safety charity has said.

This limit should be applied specifically around all schools, hospitals, as well as sporting, social and cultural venues.

But critics have said the proposals are 'so ridiculous it is simply laughable'.

The suggested areas have been targeted because they tend to have a 'particular prevalence of pedestrians and/or bicyclists and/or motorcyclists' as well as 'a heightened vulnerability of pedestrians to impact and injury', the Road Safety Foundation (RSF) said.

Single carriageways and country roads must also stick to a 20mph limit, a third of current road speeds, the charity added.
