Hazard Lights on Moving Vehicles

[SYZ]

I note that reading a review of the Chinese made Haval H9 (which sounds more like a Lebanese desert) that "there are also curiosities, such as the hazard light flashers that kick in under heavy braking. It's a common safety addition to modern cars".

Is it in fact an addition to modern cars? I've never heard of this function for hazard lights.

The Victorian road regulations—ROAD SAFETY ROAD RULES 2009 - REG 221(a) says, "The driver of a vehicle fitted with hazard warning lights must not use the hazard warning lights, or allow them to be used, unless the vehicle is stopped and is obstructing, or is likely to obstruct, the path of other vehicles or pedestrians".

What's the real story? Hazard lights okay when moving or not?
