Which of the following is NOT a regulation for moped safety?

Driving a moped on highways is generally not permissible due to safety concerns and the design limitations of mopeds. Mopeds are typically smaller and less powerful than motorcycles, which can make them less visible and less able to keep up with the speed of traffic on highways. Furthermore, laws often restrict the operation of less powerful vehicles to lower-speed roads. This keeps both the moped operator and other drivers safer, as high-speed environments are not suitable for vehicles that cannot maintain highway speeds.

In contrast, wearing a helmet, signaling when turning or stopping, and obeying traffic laws are essential regulations that are intended to enhance the safety of moped riders. Helmets protect riders' heads in the event of a crash, while signaling is vital for communicating intentions to other drivers, helping to prevent accidents. Following traffic laws ensures that all road users can coexist safely. Thus, driving on highways is the only option that does not align with established safety regulations for mopeds.
