How many brakes should a moped have?

A moped is classified as a lightweight vehicle designed for short trips, and it usually has a simple and lightweight braking system. According to Texas regulations, a moped is required to have at least one brake system that is capable of safely bringing the vehicle to a stop.

This requirement is practical for the design of mopeds, as they are generally not intended for high speeds or heavy loads, making a single brake sufficient for safe operation. While it is possible for mopeds to be equipped with more than one brake, the legal requirement is explicitly one brake, which ensures essential safety while maintaining a light and efficient design.

Other options of having two, three, or four brakes are not necessary for the operation of a moped, as these components would add unnecessary complexity and weight to the vehicle, which counteracts the primary characteristics of a moped. Therefore, one brake is the correct answer for the minimum requirement.
