Can average speed cameras fine you?
Unless you stop between paired cameras, stopping has no effect on the average speed data. No flash means no fine – Wrong.

How does average speed prosecution work?
The ASOD system calculates the average speed of a vehicle from the time it passes the first camera until it passes the second camera. The average speed is then determined by the that it has taken a vehicle to travel from point A (where the first camera is located) to point B (where the second camera is located).
The speed limit tolerance in South Africa is 10km/h. While it used to be 10% of the speed, it was simplified to allow for a smoother and more efficient system to be used.
This means that you will only be fined if you are caught going over 10km/h faster than the posted speed limit.
If a vehicle is detected exceeding the speed limit or running a red light, the camera and flash are activated to take a photo and a fine is issued.
