4.3.2. Child safety
Infants and children need special protection. The vehicle's seat belts may not fit them properly. The shoulder belt may come too close to the face or neck. The lap belt may not fit over their small hipbones. In an accident, an improperly fitted seat belt could cause serious or fatal injury.
Always use an appropriate child restraint system.
Children need adults to help protect them. They need to be properly restrained. The proper restraint depends on the child's size.
