Motorists are often unsure about this question. Here’s what the law says:
A lot of South Africans aren't sure whether hidden speeding cameras are legal or not. According to the law, they are legal, and the metro police don't have to display any warning signs about them either. It is well within the rights of traffic authorities to use these disguised devices to enforce the law. However, where average speed prosecutions take place, they do have to warn you by displaying notices to let you know about it. #StaySmart
