Sorry if these are already common knowledge.
I have bought Euro Truck Simulator 2, mostly for reversing practice. It allows in-cab, out-of-window, bird’s-eye etc. views as you practice your manoeuvres. I’m sure many of you know of it already:

Even better tho is Trucks and Trailers, by the same software house. In this one you don’t have to drive long distance between depots in order to be able to practice. You can just spend your whole time doing yard parking challenges and even play back your attempts, play backwards, pause, etc… It is available for instant download for about seven quid from Amazon:

This has been posted here before, but is a great little online reversing game:

There are also many apps on Android you can practice truck reversing with, but I’ve not experimented with them to decide which is best. I think PC is better tho because of the scale and controls. BTW on the first two games, use the touchpad or mouse or a controller to move the truck in the yard, it’s impossible with keyboard!
