Why do drivers on motorways 'flash out' HGVs when it isn't safe to do so?

Please warn your readers about a serious issue when driving on motorways. Before flashing your lights to allow a truck in front to change lanes, please think about what you are doing. If it is a foreign truck, there could very well be another vehicle in his blind spot and he may very well interpret your signal as it being clear to move over. We have just had such a near death experience on the A1. Luckily the Hungarian driver saw us just in time.

I see what you mean. 'Another vehicle' between you and the cab of the foreign HGV that the driver cannot see. Wise advice. Car drivers should never, ever hover in the blindspot of an HGV anyway. I’m also against ‘flashing’ trucks out because this can be misinterpreted. Best to keep flashing (and hooting) as a warning only.
