Seating and Safety Restraints Booster seats should be used until you can answer YES to ALL of these questions when seated without a booster seat: • Can the child sit all the way back against the vehicle seat back with knees bent comfortably at the edge of the seat cushion? • Can the child sit without slouching? • Does the lap belt rest low across the hips? • Is the shoulder belt centered on the shoulder and chest? • Can the child stay seated like this for the whole trip? Types of booster seats There are generally two types of belt-positioning booster seats: backless and high back. Always use booster seats in conjunction with the vehicle lap/shoulder belt. • Backless booster seats If your backless booster seat has a removable shield, remove the shield. If a vehicle seating position has a low seat back or no head restraint, a backless booster seat may place your child's head (as measured at the tops of the ears) above the top of the seat. In this case, move the backless booster to another seating position with a higher seat back or head restraint and lap/shoulder belts, or consider using a high back booster seat. • High back booster seats If, with a backless booster seat, you cannot find a seating position that adequately supports your child's head, a high back booster seat would be a better choice. 157
