How the Booster Tag works
Designed to keep kids safe
keep kids safe
The Booster Tag is a simple new way for parents to know if kids still need to use a booster seat, based on the clothing they wear.
If a child fits clothing displaying the Booster Tag, that means they’re still likely to be under 145cm tall and safest travelling in a booster seat on our roads – no matter how old they are.
Once a child has outgrown clothes displaying the Booster Tag, check they’re seatbelt-ready with the 5-Step Test.
Booster Tag matters
Many parents are moving their kids out of a booster seat too soon, unknowingly putting them at risk.
In fact, less than 3% of parents know that children should be at least 145cm tall to safely travel without a booster.
If a child shorter than 145cm rides without a booster seat, the seatbelt will sit too high on their body, resting against vital organs. That makes it more than 3.5 times more likely they’ll suffer serious head, neck, spinal and abdominal injuries in a crash.
That’s where the Booster Tag comes in. It gives parents a simple reminder that their child still needs to use a booster seat, helping keep kids safe on our roads.
It’s about height, not age
When it comes to booster seats, what matters is the child’s height – not their age, because all kids grow at different rates.
Some children may reach 145cm at age 8 or 9, but most won't get there until around 11 or older.
No matter how old a child is, if they fit a size 4 t-shirt, they’re probably around 108cm tall and if they fit a size 11, they’re getting close to 145cm tall.
That means that any child who fit a size 11 t-shirt or smaller, is likely to be under 145cm and should still be in a booster seat, regardless of their age.
The 5-Step Test
Is your child 145cm tall and ready to ride without a booster seat?
Every car is different, so once your child has outgrown clothes displaying the Booster Tag, check that they’re seatbelt-ready with this 5-Step Test.
Get them to try sitting in your car’s rear seat. Then make sure you can check off all of these:
Lower back against seat
Sash belt against shoulder
Knees bend over seat
Lap belt low against hips, touching thighs
Child stays in position for whole trip
