Aye, we used the original Range Rover and the P38 to shift artics off the carriageway. Sure, they'd be in low range and only moving maybe 30 or 40 feet, but they did it. Mind you, so did the Land Cruisers that replaced them.
Useless factoid - for the purposes of clearing a highway obstruction a bobby in uniform can drive any category of vehicle, regardless of whether or not they have the entitlement on their licence.
The Wombles can't.
Saw two idiot Wombles on the M1 yesterday merrily chatting away with thekr backs to the oncoming traffic, but that's for another thread I guess.
