Good Afternoon

Could anyone please tell me if the below law is correct in the South African context.

If the incident occurs when automobile “B” is entering a road from a private road or a driveway and automobile “A” is passing the private road or driveway and, if there are no traffic signals or signs, the driver of automobile “A” is not at fault and the driver of automobile “B” is 100 per cent at fault for the incident.

Thank You
