Just a bit of fun - Be gentle with the keys for best control!
Up & Down Keys - Accelerate & break, then again to reverse.
Left & Right Key - Turns steering wheel (release to let it return back
to the center).
Space Bar - Detach rear cargo Container from lorry... It will
reattach if you carefully realign yourself :)
***Updates***
