You can leave side windows and have a net or barrier to catch broken glass, I would argue the same for a sun roof, but catching it would be quite a bit harder and I think is more of a grey area.
Well... no. You can leave side windows behind the driver in place without any sort of net or barrier. If you want a net or barrier, fine, but it's not in the rules.
For the front doors, and only the front doors, if the glass is retained then it must be in the down position and behind "fully encasing door panels" not just a net.
Glass above the driver must be removed, whether we're talking t-tops, moon roofs, or any other glass up top. You can either leave the resulting hole open and wear arm restraints or fill the hole with "sturdy non-breakable material" but the glass itself has got to go.
pretty sure that hatch glass has to come out.
Nope. Hatch glass can stay.
