Regarding the speed question that has also been answered it also depends on what road your on:
Motorway 60MPH (doubtful due to limiters)
Dual Carriageway 50MPH
Single Carriageway 40MPH (YES! Only 40)
I know the speed limits for lorries but why do the others speed then? I see some doing 56mph on a NSL A road and others doing less than 40? I would say it's a 50/50 split between the speeders and the ones that stick to the limit. I always thought the slow ones were on the clock and wanted to get their hours in .
