Are 5 point harnesses street legal?

Question

I was thinking about adding a 5 point seatbelt harness to my car and was wondering if it was street legal

Answer 1

yessir, it is an added security feature, not nitrous.

Answer 2

yes they are.

Update...I found this and though it might be helpful.

A 5-point harness will not work properly with an extremely reclined seating position. Imagine the extreme case of a fully reclined position. In this case the lap belt and shoulder harness serve no function but to hold the body down. The occupant will slide out from under the lap belt. In this case a 6-point harness acts like a parachute harness and it restrains the occupant by the pelvis. For a 6-point harness to function it must wrap under the legs and not straight down.

Answer 3

yeah it is legal , any I.H.R.A. approved  restraint exceeds D.O.T requirements

Answer 4

sure they are legal, make sure you mount it correctly that harness an a good seat gives you a good platform to drive the car
