First Kiss safety campaign

Earlier in 2016, the Western Cape government made a shocking ad in a bid to make South Africans buckle up when driving. The controversial ad made such a huge impact that it is now being aired in the UK too.

Western Cape MEC, Donald Grant, said at the time: "Vehicle occupants (drivers and passengers) continue to constitute the majority of all road deaths in the Western Cape. Research has shown that increased seatbelt compliance will mean thousands of lives saved, that would have otherwise been lost, in the horrific crashes that plague our roads."
