As Rib007 has said, the sad fact is that Manafacturers and Legislators are unlikely to ever see eye to eye on this one, so an AS is unlikely to be prepared. It was a big enough issue getting them legislated for new tractors and ensuring all second hand tractors re-sold have them retro-fitted. A huge issue with the amount of quads about tho.
At least worksafe in Victoria have gone out and endorsed users "consider fitting them". A weak response some may say, but at least its something.
My daughters lost a school mate at state school when they were in year 6. It was very lucky that two wernt killed. Both went straight over the back when the unit flipped.
Most ATV manuals now say "minumun age 16, rider to be trained" or something similar.
Most rural TAFE's offer an ATV Users Course at part of their rural studies short courses. They might seem to be a "learn how to suck eggs" course for some, but id recommend one for all.
