Road safety is the topmost priority of the government, which has set a target to reduce accident deaths by 50 per cent by 2030, Union Minister Nitin Gadkari said on Tuesday.

Addressing an event organised by industry body CII, Gadkari further said change in social behaviour is very important along with focusing on strengthening '4Es' of road safety -- Engineering (road & vehicle engineering), Enforcement, Education and Emergency medical service.
