Florida car seat law for a truck?

I'm 13 weeks pregnant and my boyfriend drives an 07 Ford F150. What are the car seat regulations for a truck? He needs this truck for work so he can't trade it in and we don't have enough funds to buy another car. The truck is all we have but I don't think it's safe for a baby… Is it even legal to have a car seat in the front seat of a truck? It doesn't have a backseat either.

If there are airbags simply for safety these need to be switched off. There should be a switch to do this. Without this the law is irrelivant it can kill your baby.

If the car seat is in the front passenger seat the air bag must be turned off. There's a keyhole somewhere to do that
