'Twas interesting then when doing the LGV / PCV training the instructor commented that "you old guys understand engine braking" ....

For those that don't know ... it is an immediate "fail" on Lorry/truck/bus to brake and clutch at the same time (except when coming to a halt), and to "skip" a gear on the way down ... you brake OR you change gear ... never both at the same time.... (all to do with potentially winding 40 odd tons of freewheeling energy back into the system should you do it ...) .. and you work your way down the box. It was part of the test to work up the box and then back down in a designated area.

I'm sure the regular (and current) truckers will correct me if it's changed ..
