Trial run

I caught sight of this early this morning and rushed for the camera...

They were obviously having a trial run using the type of lorry that wind turbine parts arrive on, checking to see that it can get round the bends in their new roads...

So...
That's the trial run, when's the real thing?

Note 1: The cars behind the lorry are not a traffic jam. They are all the bosses.

Note 2: These lorries are fitted with remote rear wheel steer. In this case a bloke is walking behind with the controls in his hand, but they do give him a car to ride in for the actual turbine deliveries!
