To avoid dazzling drivers behindThis was the right answer

High-intensity rear fog lights are to be used when fog has seriously reduced visibility. Using them at any other time runs the risk of dazzling drivers behind. A warning light will show on the dashboard to indicate when your rear fog lights are on. You should know the meaning of all the lights on your dashboard and check them before you move off and as you drive.
