When transporting a passenger on a motorcycle, it is essential for them to lean as you lean. This action helps maintain balance and stability while riding, especially during turns or changes in speed. If the passenger leans independently or remains rigid, it can shift the motorcycle's center of gravity and potentially make controlling the bike more difficult, increasing the risk of an accident.

Achieving coordination between both the rider and the passenger is crucial for safe operation. Therefore, leaning together ensures that both parties are working in unison, which enhances safety and reduces the likelihood of losing control. Adjusting to the rider's movements not only supports balance but also makes for a more comfortable ride for the passenger.

In contrast, sitting still at all times could lead to instability, especially when navigating curves. Holding onto the backrest can provide a sense of security, but it's not as effective in maintaining balance as leaning together. While wearing a separate helmet is vital for safety, it does not directly relate to how the passenger should position themselves in relation to the rider on the motorcycle.
