Don't be so aggressive!

Then there are the 'aggressive flashers' - these guys come up behind you on fast moving motorways and dual-carriageways 'telling' you to get out of the way.

I have even heard advanced driving instructors explaining how this can be done safely (quoting Roadcraft). My thoughts on this are that there is nothing 'advanced' about aggressive driving.

Assuming, of course, that your signal is seen .

'Aggressive flashing' can perhaps be justified when used by emergency vehicles and executed as advised in Roadcraft; although it doesn't always work.

I remember dark evening on the M62 when I was travelling as a passenger in a police car - hurtling along lane-three at about 115 mph we had more flashing lights than Blackpool Illuminations, but there were still drivers ahead who were totally oblivious to our presence!
