What instructions should a driver give a passenger before attempting to drive with an M2 or M license?

Answer: D — Instruct the passenger to get on, sit as close to the driver as possible, and hold the driver's waist firmly.

The correct choice is focused on ensuring the passenger's safety and maintaining good balance while riding. By instructing the passenger to sit as close to the driver as possible, this option emphasizes the importance of stability. Keeping the passenger close helps maintain the motorcycle's center of gravity, which can enhance control, especially during turns and accelerations. Holding the driver’s waist provides the passenger with a secure way to stabilize themselves without interfering with the driver's control of the motorcycle. The other options suggest positions or grips that may compromise safety or balance. For example, sitting too far back could lead to an unstable riding experience, as it can shift the motorcycle's weight distribution unfavorably. Similarly, instructing the passenger to hold the handlebars or the driver's shoulders may distract the driver or impede critical controls needed for safe operation. Thus, this choice prioritizes both the driver’s control and the passenger’s security.
