South African Police are blocking all the transportation to check if the passengers have the permits to be on the roads. You are only allowed to be on the streets if you have a permit of being on the road from your workplace or when you go to the shops and you won’t be allowed to walk in pairs.
There are also people who are stopped on the road for them to provide the permits of being on the streets. This is a fearful virus and we need to take it serious and avoid being on the streets without reason until the lockdown is over or else the President will be forced to postpone it until they come up with a solution.
If you want to go purchase food you need to do it in the morning or in the afternoon as during the day everyone is expected to be at home.
