Yes, we find it surprising, too. But, parents & mentors, take heed. Help kids to stay safe by following these guidelines:

In Vermont, to get out of a booster, a child must pass two milestones

  1. The child must be 8 years old to even consider leaving the booster.
  2. The child must pass the 5 step test to get out of the booster. The belt must fit them correctly. This test checks for belt fit.

The 5 Step Booster Test:

  1. Does the child sit all the way back against the vehicle’s seat?
  2. Is the lap belt below the stomach, touching the thighs?
  3. Is the shoulder belt centered on the shoulder and chest?
  4. Do the child’s knees bend comfortably at the edge of the vehicle’s seat?
  5. Can the child stay seated like this for the whole ride?
