Does anyone know about child car seat laws in France?

[NotActuallyAMum]

A friend of mine is taking her granddaughter to France in a few weeks, she's 7 and tall for her age (about 4ft 5). Will she need a seat/booster of any kind or can she go without?

If they are driving there then she will need a booster seat anyway.
If flying and getting a hire car, i would book one.
Better safe than sorry.
We took our DD2 to France and the state of the stage one car seats is really bad, ended up borrowing a friend's carseat when we were out there with them.

Pretty sure it is up to age 10 require them here

Thank you both

Does look like she needs one, I'll let her know, thanks again
