Pre-school to 8 years old
The law requires booster seats for children who have outgrown a child car seat but are too small for a regular seat belt.
Booster seats are required for children under the age of eight, weighing 18 kg or more but less than 36 kg (40-80 lb.) and who stand less than 145 cm (4 feet-9 inches) tall.
A child can start using a seatbelt alone once any one of the following criteria is met:
child turns eight years old
child weighs 36 kg (80 lb.)
child is 145 cm (4 feet-9 inches) tall.
Seatbelts are designed to protect adults. Booster seats raise the child up so that the adult seatbelt works more effectively. Booster seats protect against serious injury 3 ½ times better than seatbelts alone.
A lap and shoulder combination belt must be used with all booster seats. Your child's head must be supported by the top of the booster, vehicle seat or headrest. The shoulder strap must lie across the child's shoulder (not the neck or face) and middle of the chest, and the lap belt must cross low over the hips (not the stomach/abdomen). Never use seatbelt adjusters.
Between 18 and 36 kg (40—80 lb.)
Booster seat
Use with lap and shoulder belt

Youth
Seatbelts are designed for adults and older children. Once your child can sit all the way against the vehicle seat back with legs bent comfortably over the edge of the seat, and with the shoulder belt flat across the shoulder and chest, he or she is ready to move from the booster seat to the vehicle seatbelt.
Make sure the shoulder strap lies across the child's shoulder and the middle of the chest (not the neck or face), and the lap belt crosses over the hips (not the stomach).
Children under 13 years of age are safest in the back seat. Never put two children in the same seatbelt or place the shoulder strap behind the child's back.
Use a seatbelt for every trip and teach your child to wear a seatbelt by always wearing one yourself!
36 kg (80 lb.), or 145 cm (4', 9”) tall or 8 years old

成人安全带是为成年人的坐高设计的，成年人系上安全带后，肩带部分正好在锁骨上， 腰带部分正好在胯骨处， 一旦有撞击， 骨骼可以吸收一部分撞击力度。 如果小孩光用成年人安全带，肩带部分在脖子的位置，那里有一根重要的大动脉和颈部脊椎， 一旦发生撞击，就有可能受重伤。 有的儿童坐在车上， 脚的长度还不够， 他们就会有意识的把身体往下挪，以便双脚触地， 但是， 这时候 腰带部分就卡在小孩的腰部了，发生撞击时，安全带勒住腰部，可能导致体内多个器官和腰部脊椎受损。 这些情况被命名为安全带综合症。 预防这一问题的方法很简单， 给孩子加一个儿童坐垫（booster seat），抬高他们的坐高， 这样安全带正好处在锁骨和胯骨处。
