NEARLY 80% of people think 20mph speed limits should be the norm around schools, in residential streets and in village, town and city centres, according to a survey.

Of the 1,000 people surveyed, 78% backed the 20mph campaign run by Brake, with 72% saying roads in their town or village need to be made safer for walking.
