What is the purpose of a Restraint Device on amusement rides?

The purpose of a Restraint Device on amusement rides is primarily to ensure that riders are securely held during the ride. These devices are critical for maintaining rider safety, as they prevent individuals from being ejected from their seats or experiencing excessive movement that could lead to injury. The design and function of restraint systems are carefully considered to accommodate the dynamic forces that riders may experience, such as acceleration, deceleration, and inversion. This safety feature plays a vital role in allowing riders to enjoy the experience without the worry of personal safety, as it keeps them securely in place throughout the duration of the ride.

While the other options might suggest benefits related to aesthetics, performance, or operational efficiency, they do not capture the core function of a restraint device, which is fundamentally about rider security and safety.
