Scania dustcart with that little bit extra on the back...Biglorryblog explains why.

Biglorryblog reader Trevor Wood has kindly sent me this picture of a multi-axle Scania dustcart operated by Viridor, featuring a trailing, steered-axle behind the double-drive back bogie. Trevor says: "It was taken at Dover sea front." And why the extra axle at the back? Well the simple answer is that those rear-end compactor bodies are pretty heavy anyway, and especially when they're close to full, so the extra axle at the back prevents any acidental overloads. And by making it a steered unit you at least get some life out of the tyres and make the eight-legger just that little easier to turn!
