damn posted without being logged in so have to explain better in second post, I mean with the quote (a few meters to the front and rear) not in front of you or behind, but if someone is to either side with in a few meters ahead or behind. i think the ahead one is only a few feet as you should not be trying to change into a lane when someone is a inch ahead in the next lane lol…. but light lights for me before any section of their car is alongside me. when they approach from the rear ?… oh dear all this rear talk, behind and approach… reminds me of carry on movie eek
