does a 10 years old need to be in a booster seat?

[Hagit]

hi,
we have a 10 & 7 years old and expecting our third.
I'm would like to fit them all in a 2009 Subaru Forester.
so my question is: my 10 years old weight about 55lb and she 51" high does she need to be in a booster? it looks like the middle seat buckle fit good on her.
thanks

	Booster Seat A booster seat raises your child up so that the car's lap and shoulder belts fit correctly. The lap belt should fall across the upper thighs. The shoulder belt should go across the middle of the shoulder and chest. A booster seat is used for older children up to about 80 pounds. Some states have passed laws requiring booster seats for children up to age 8 or 80 pounds. Check your state's law. Ready to buy a Booster Seat? Please support our sponsor!

A few things. First, can she pass the 5 step test Boosters Are For Big Kids ? If she canNOT, then she still needs to be in a booster. Secondly, does the middle position offer a lap/shoulder belt or a lap belt only? If it is a lap belt only, I would NOT put her there as there is no upper body protection. Lastly, I would put her in a seating position that offers a headrest for head/neck support.
