Best Practices for the Use of Child Restraint Systems

Until NHTSA publishes federal guidelines for pre-kindergarten transportation, here’s what you need to know about child restraints, seat belts and seat anchorages.

The growing population of infants, toddlers and preschoolers on school buses presents a wide range of challenges to the transportation provider. Many of these challenges test the operator's knowledge and experience. I know this because I field calls every day from conscientious, compassionate school bus professionals who are desperate for information on how to safely transport these youngsters. A good starting point for school bus operators is to ensure that their equipment - including child safety seats, seat belts and seat frame anchorages - conform to federal motor vehicle safety standards (FMVSS). Using proper restraint
Although many child restraints are available, there is no single safety seat that is best or safest. The important thing is that the child restraint meets the performance requirements of FMVSS 213. This information should be listed on a label attached to the child safety seat. The type of child restraint that you choose will depend on each child's needs. For example, a safety seat with a shield should not be used with a child who wears glasses, which could injure the youngster if he or she is pitched forward during a sudden stop. If possible, test a variety of child restraint systems before buying one. You might even want to drive the school bus to the vendor's shop for on-the-spot testing. Another important aspect of using a child restraint system on a school bus is making sure that it is secured with seat belts that meet FMVSS 208 (occupant crash protection) and 209 (seat belt assemblies). Be especially careful to ensure that aftermarket seat belts meet these standards. There are seat belts designed for positioning purposes only, and they should not be used to secure a child restraint. Once you've confirmed that the child restraint and the seat belts meet federal safety standards, you have one more piece of equipment that you must check - the seat belt assembly anchorage. These seat frames must meet FMVSS 210, which ensures that anchorages for seat belt assemblies provide effective occupant restraint. All school buses with a gross vehicle weight rating (GVWR) below 10,000 pounds are required to comply with standards that apply to occupant protection. Thus, they must have federally approved seat belts and anchorages. Meanwhile, manufacturers of school buses with a GVWR of 10,000 pounds and over voluntarily comply with these standards. If belts are installed at the point of manufacture, they will meet the federal standards. If a school district intends to add seat belts to an existing bus, it is crucial that the manufacturer of the vehicle is contacted to see if retrofitting is possible. Anchoring seat belts to a bus seat frame that does not meet federal specifications could jeopardize the securement of the child restraint. Keys to securement
Once you've ascertained that all of the equipment meets federal standards, the next step is to properly secure the safety seat. Before using the child restraint, it's important to read the manufacturer's instructions on proper installation and usage. If you no longer have the instructions, the manufacturer can provide them if you know the model number and date of manufacture. As a rule of thumb, infants should ride facing the rear of the vehicle until they're one year old or 20 pounds. A child weighing 20 to 40 pounds should face forward. Manufacturers' guidelines may vary slightly. In the case of a child that has outgrown a child restraint - and yet would not benefit from compartmentalization - we recommend that the bus operator use a vest restraint. Each child safety seat has a designated path to route the seat belt, depending on how it is used. The seat belt should be pulled tightly while putting weight into the child restraint. After you've secured the child restraint system to the bus seat, you need to secure the infant or toddler in the safety seat. This involves placing the harness straps over the child's shoulders so they're snug, allowing only one finger between the strap and the child's body. Some child restraints have a retainer clip that keeps the harness on the child's shoulders. The retainer clip should be positioned at armpit level. A quick way to determine if a child has outgrown a child restraint is to see if his or her ears are above the top of the restraint. If so, the child is too tall for the restraint. If you are unsure about a child restraint, or you are having problems with it, contact the manufacturer. To see if it has been recalled, call the National Highway Traffic Safety Administration's Auto Safety Hotline at 800/424-9393.
