§ Mr. ElletsonTo ask the Secretary of State for Transport what evidence he has that the experimental 20 mph zones are reducing accidents; and whether he will make a statement.
§ Mr. Kenneth CarlislePreliminary indications are that 20 mph zones reduce casualties by well in excess of 50 per cent. There have also been small reductions on surrounding roads. It is particularly pleasing that they seem to be especially effective in reducing accidents to children.
