It’s Child Passenger Safety Week September 17–23, 2017.

If you are in a car accident, you expect your child’s car seat to perform, to do its one and only job and keep your child safe from harm. But installing a car seat correctly is harder than you might think.

How hard is it? A research study at Oregon Health and Science University Hospital showed that parents are struggling. While observing parents adjust and install their car seat for their newborn’s discharge from the hospital, they found that 95 percent of parents made at least one error, with an average of more than 5 errors per car seat.

The most common harness adjustment errors:

  • Harness too loose (69%)
  • Chest clip too low (35%)
  • Wrong shoulder harness slot (31%)
  • Use of after-market product not approved with seat (21%)

The most common installation errors:

  • Seat belt not locked tight (53%)
  • Car seat installed too loosely (44%)
  • Recline angle of car seat incorrect (41%)
  • Using the wrong seat belt path (23%)

Surprisingly, even experienced parents made as many errors as parents bringing home their firstborn.

There is a solution. This study also found that the best predictor of correct car seat use was working with a certified Child Passenger Safety Technician (CPST). Families who did so were only one-tenth as likely to make serious errors.

Car crashes are a leading cause of death for children — but correct use of a car seat reduces the risk of death in a crash by up to 80 percent. Are your children riding safely?
