Is 5 too old for 5-point harness?
Is 5 too old for 5-point harness? Young children under age 5 or 6 are safer in a 5-point harness car seat. Don't rush to “graduate” your child to a booster seat. If your 5 or 6 year old still fits in their 5-point harness car seat, leave them there!
Is it illegal to have 6 passengers in a 5 passenger car UK?
The law doesn't currently prevent you from carrying more adult passengers than there are seat belts. However, children up to 135cms tall must use child restraints with few exceptions, which means they must use the seats in the vehicle that have seat belts to secure their restraints. This can limit carrying capacity.
