    Abstract: Safety belts should be worn by children at all
times, particularly on the express way. However, it has
been reported that the safety belt-wearing rate of children
is only 30% on the express way, despite the need to have
belts on constantly. It has also been reported that children
aged 5~6 years old could be thrown out of the car if it
were hit by an object at a speed of >50 km h<sup>&#150;1</sup>. Therefore,
some testing experiments were performed in accordance
with code 2009~No. 0977 of the Products Safety
Managing Act. Namely, 3-year-old dummies were used in
the test. It was found that commercially purchased
products are not made in compliance with requirements.
