how old do you have to be to not sit in a car seat
You had better be sitting down in a car...and with your seat belt on. Children under 10 cannot be in the front and better have a child seat in the back! France is very strict about this. 10 years old. (In France children are prohibited from travelling in the front seat until aged 10 years old. Source(s): Live in France with a 11 year old.
