Hook and Ladder Fire Truck

I was fortunate to share a long stop at a traffic light with a hook and  ladder fire Truck (also called a tiller truck).
The truck was prepared to make a 90° turn at the intersection. 
It was occupying two lanes...all of its front wheels in the left lane and its two rear-most wheels in the right lane.
Sadly, I had to move on when the light changed to green, and so I missed the choreography of the truck turning the sharp corner with each end stepping differently for a bit.
