It isn't taught in any formal drivers training in the US (although manual is hardly taught anymore.) Also, I'm pretty sure if you took a CDL test and used your airbrakes on a hill, they would fail you. It wasn't allowed when I got taught anyways. Maybe that has changed?

A big truck will take much longer to start rolling back so I'm betting it wouldn't be as useful for them. Does it matter if the technique is 30 years old instead of 80?
