There may be a deed of covenant which stipulates no work vehicle on the site. Did you sign anything similar when you moved in?
I am awoken each morning by my neighbours, either the boy racer and his huge exhaust which I can hear as he leaves the street and still hear it when he reaches the other end of the village. And my other neighbours who run their deisel 4 X 4 for about half an hour while getting the kids, their bags and each other in. I slept with my window open last night and I had several lung fulls of overpowering exhaust fumes this morning and I live 3 floors up. Yuck.
Someone complained ot my plumber friedn about his van being parked outside his house, he just pointed to his tax disc and said "see that? It means I can park where I like". I don't know about lorries though, sorry, just wanted to hijack your thread and grumble a little.
