At night, if you must stop your car on an ordinary road, turning on the hazard lights or setting out a warning device is entirely optional.

Explanation

Incorrect. At night on an ordinary road you must make your stopped car visible to others, either by switching on the hazard lights or by placing a warning device. It is a duty, not a choice. (Source: Rules on Traffic Methods, Ch.10 Sec.2)
