will the likes of a luke or willans 4 point harness pass the sva.if not what type will and where could i get .

e marked is a guaranteed pass for sva. push button clasps are best, aircraft twist style ones can pass, though have to be able to undo them with one hand.

I think you will find all harnesses can be undone with one hand, its a motorsport thing...

IIRC its one hand and in one direction only (ie no twist and pull etc)
