Child booster seat lap belt

[yonamamati]

Hello, Could anyone advise if a 10 yo child can travel in a booster seat, rear facing with a lap belt?
Do you have any reference of the rules and regulations applicable please?
Thank you

Hi, and welcome
I'm afraid I'm not personally up to date on this.
LIZZIE - Can any of our magazine experts give chapter and verse on this?
