Annother thing to consider when discussing forklift roll-overs (with sit down counter balanced machines) is that those who jump off are almost always killed or severly injured because human nature is to take the path of least resistance, which is the low side. I have only ever had to recover one rolled over machine in all my years in this buisness, and thank fully that operator stayed in the seat despite not having a seat belt.

This is a bit off topic, but I have seen a crown produced saftey video featuring a crash test dummy, RC3000, an un chokked flat bed trailer and an automatic dock leveler. It didn't end well for the dummy when the trailer rolled away.... I think that all forklift operators should be required to watch a bunch of safty videos of that type at least once a year, probably every one who works around theses machines should watch them periodicly
