am I allowed to remove the rear seats on my car?

You would have to ask the inspection center as these rules change by area. If it wasn't for the inspection you could totally remove seats. Alex

Here in Virginia > Only the drivers seat is 'required' and it must be approved including all restraint system related to that seat - IF no other seats are present - then they can't be inspected. IF other seats ARE present - they must also meet the same approval.
