Keep the tips coming guys. I only wish we could place your post in the Roadcraft category.
When ever I pull up behind a large vehicle -- SUV, truck, bus, whatever, I make sure I'm on the left side of the lane and far back so I can see their side view mirrors. This also will allows me to see what's coming down the opposing lane of traffic in case someone makes a left hand turn. If I was behind the truck in the middle or right section of the lane, the drive wouldn't know I was there, nor would a left hand turner in the opposing lane.
See and be seen,
