When you've stopped your vehicle and it's temporarily obstructing trafficThis was the right answer

Use hazard warning lights when your vehicle is stationary, to warn that it's temporarily obstructing traffic. Never use them to excuse dangerous or illegal parking. You may also use hazard warning lights while you're driving on a motorway or unrestricted dual carriageway if you need to warn traffic behind of a hazard ahead.
