Which statement is true regarding the riding position of a moped operator?

The statement regarding the riding position of a moped operator that is true is that they must sit in a regular, permanently attached seat. This requirement is in place for safety reasons, as sitting properly in a designated seat helps ensure better control of the moped and reduces the risk of falls or accidents. The design of mopeds is typically such that they are meant to be operated while seated, allowing the rider to maintain stability and balance.

In contrast, standing while riding or leaning over the handlebars can compromise the rider's ability to steer and control the moped effectively, increasing the chances of accidents. Riding double, or carrying a passenger, is also generally restricted, as many mopeds are not designed to safely accommodate an additional person, which can affect weight distribution and overall handling. Adhering to the requirement of sitting in a proper seat contributes significantly to the safe operation of mopeds on public roads.
