Child Safety
•Problem: Motor vehicle collisions are the leading cause of serious injury and death among Canadian children
•Solution: Risk of serious injury or death is significantly reduced when children travel in a restraining device that is size- and age-appropriate
Booster Seats
•Problem: Children older than 4 years of age are often:– prematurely moved into adult seat belts– susceptible to serious life-threatening
injuries caused by seat belts during motor vehicle collisions – “seat belt syndrome”
•Solution: Booster seats use is an effective injury prevention strategy for children 4 to 7 years of age
Ontario’s Booster Seat Law
•Objective: To enhance the safety of children and youth on Ontario’s roads
•Regulations: A child must be properly restrained in a booster seat when riding in a motor vehicle until 1 of the following 3 criteria is exceeded:– child weighs more than 36 kg (80 pounds)– child is taller than 145 cm (4’9”)– child is 8 years of age
•Implemented: September 1, 2005
Objectives
•Overall objective: To evaluate the effectiveness of Ontario’s booster seat law
•Specific objective: To provide a comparison over time regarding the % of children 4 to 7 years of age who are reported to use a booster seat in Ontario
•Past research: Parents rely on laws as guidelines on how to properly restrain their children

Conclusions
•Overall increase in booster seat use after September 1, 2005
•Increase in booster seat usage is related to child’s age: – only among 6 and 7 year olds
•Significant proportion of 4 to 7 year olds are still not using booster seats: – prolonged car sear usage among 4-6
year olds– premature graduation to sit belts among
7 year olds
Implications
•Need to improve community awareness regarding the health risks of not using booster seats among 4 to 7 year olds
•Booster seat campaigns should clearly state weight, height, and age requirements
