For escape hatches on buses of Classes A and B, proposal to allow a maximum length of 1600 mm equally spaced to cover the shortest vehicles, so the allowed space should be the maximum of either the third of the length or 1600 mm. This proposal will not affect the positioning requirements for any mid-sized and larger buses.

Revised proposal to allow an alternative positioning and spacing of escape hatches on buses of Classes A and B to address limitations for shorter vehicles.
