Front seat illegal?

[momplus6]

Its not illegal that I'm aware of I do it as there not enough seats usually for short distances and not on highways. You may want to check what your booster seat manual says(because I believe if you don't follow the manufacturers instructions thats illegal) I believe some of them say don't use in front seat. Make sure you put the seat all the way back. I just realized you said the airbag can be turned off then that is totally fine just double check the booster seat but I'm pretty sure the manual I saw said with active airbag.

It is not illegal, as some trucks do no have backseats (one my dads drive a truck like this). The airbag needs to be off and the seat installed as per the manual. If you have an early years centre near you they have really good classes on carseat safety and installation.
