Many are rarely, if ever taken onto rural roads. Where I live near Wimborne Minster in Dorset I am lucky in that I have access to virtually all types of road from the busy towns of Poole and Bournemouth to small market towns like Wareham, Blandford Forum, and Sturminster Newton. Also the county town of Dorchester with its three lane section A37 by pass, allong with NSL dual carriageways and single carriageway roads. I am also in reach of several single track roads and some good NSL B roads, the B3081 to Shaftesbury incoporating Zig Zag Hill springs to mind.

Most young drivers think that the speed limit is a safe speed, and are then surprised when they encounter a bendy single track NSL road. This NSL road in Corfe Mullen usually causes comments like,"It should have a 30 mph limit.

The usual reply is, "Could you stop at 30mph if a tractor was coming in the opposite direction?"
I rest my case.
