What should a passenger do when you make a turn on the motorcycle?

When making a turn on a motorcycle, it is crucial for the passenger to hold on securely to the rider's waist. This action ensures that the passenger maintains stability and minimizes shifting of their weight during the turn. Holding on also allows the rider to have better control of the motorcycle, as the passenger's movements directly affect the balance and dynamics of the bike during corners.

Proper posture and grip enhance safety for both the rider and passenger, contributing to a harmonious riding experience. The other options may suggest actions that could destabilize the motorcycle or distract the rider, which is why they are not advisable in this context.
