Carseats and trucks

Mercedes • 👨‍👩‍👦‍👦

Right now the plates on our car are expired, so that leaves me with the truck while my boyfriend is away for work out of state. I've never tried to put my boys in there and not sure how to do it safely. Google is giving me mixed answers. So I was wondering if any of you have done it, is it even allowed? My boys are 1 and 2. I wasnt sure if it was allowed because technically they're in the front seat? Idk any advice would help.
