Can mopeds travel on roads with a "motor vehicle only" sign?

Mopeds are classified differently from motor vehicles in Japan. When you see a "motor vehicle only" sign, it indicates that access to certain roads is restricted to larger, motorized vehicles. Since mopeds do not meet the criteria typically associated with motor vehicles, they are not permitted to travel on these roads. This is to ensure safety, as these roads are designed for vehicles that can maintain higher speeds and offer more robust safety features than mopeds.

The other options suggest varying degrees of permission or exceptions that do not apply to mopeds, reinforcing the idea that they fall under different regulations compared to standard motor vehicles.
