How can I ensure proper car seat strap safety for my child?

To ensure proper car seat strap safety for your child, make sure the straps are snug and secure, with no twists or slack. Position the chest clip at armpit level and ensure the harness is at or below the child's shoulders. Regularly check for proper installation and adjust as needed. Follow the car seat manufacturer's guidelines and consult a certified child passenger safety technician for assistance if needed.
