South Africa's Minister of Transport, Fikile Mbalula, has announced that the country's strict new driving laws will be introduced in June 2020. The new Administrative Adjudication of Road Traffic Offences (Aarto) Act will include a 0% legal blood-alcohol limit, meaning that drivers will not be allowed to drink alcohol and drive at all.
As of now, the blood alcohol content (BAC) in South Africa must be less than 0.05 gram per 100 millilitres (0.05%) for normal drivers and less than 0.02 gram per 100 millilitres for professional drivers (0.02%).
