This braindead driver in a Walters Highway Maintenance van pulled across from the outside lane into my lane while braking and also approaching a red traffic light. There was no thought whatsoever that he had just completely taken my safe stopping gap and that driving a loaded lorry I may not be able to stop without hitting him. If I hadn't been paying attention I would have disappeared up this prick's arse. You might want to engage your braincell before doing anything so stupid in the future!!
