Assessing whether a child is ready to use an adult seat belt: The "5-step test" can be used to determine whether a child is big enough to obtain optimal protection from adult seat belt (see the box below).

The Five Step Test:

 

               1. Can the child sit with their back against the vehicle seat back?
  2. Do the child's knees bend in front of the edge of the seat? 
    3. Does the sash (shoulder) belt sit across the middle of the shoulder, not on the neck or out near the arm?  
    4. Is the lap belt sitting low across the hips touching the thighs?  
    5. Can the child stay seated like this for the whole trip?  

If you answered "Yes" to all 5 Questions, then your child is ready to move out of a Booster seat, into an Adult seatbelt.

If you answered "No" to one or more, then they still need a booster seat.
