If we take you as an 'averge' lorry driver (not that I'm suggesting there's anything average about you) would it be safe to assume that most lorries have a near miss/incident at least once every three years?
I'm sure I'm average! Neither the best nor, I hope, the worst!
Alas, near misses are probably weekly occurrences(!) it's why we're trained to "drive defensively", were encouraged to take up as much road space as possible to prevent other vehicles trying to come past if we know we need the space they intend to take. Often this is taken as agressive by the other drivers, they don't seem to realise we're allowing for them and often preventing them getting flattened!!
Most road users take unbelievable risks around HGVs whilst seemingly being oblivious to the consequences of that risk going bad.
This style of driving I guess must work, bar a car aqua planing into me on the M1 a few years back I'm yet - touch wood - to have an incident / accident involving a 3rd party whilst driving my HGV.
Near misses are sadly part & parcel, if I had £10 for each one, I'd be rather richer than I am!!
