Filtering on Motorway

[Slaninar]

Stationery vehicle for hazard lights. So how come Renault got away with making my hazards come on automatically when I slam the anchors on (really got to slam them on) in my Scenic? I don't buy that you should only use them stationary, and yes, I think it's a good idea to use when filtering past stationary traffic. Not so good for filtering past anything going faster than a crawl though (I class undertaking slow outside lane hogs on a motorway as filtering too, I wouldn't use hazards here).

They come on when slaming the brakes and only when really slaming? You need explanation on that?




The law in my country says only when stationary, moving backwards and when there is dense fog. Oh, and I thing, when towing a vehicle, but not 100% sure.
