Passengers should:

Answer: A — Lean as you lean.

Passengers should lean as you lean to maintain balance and stability on the motorcycle. This technique allows both the rider and the passenger to shift their weight together during turns and when navigating obstacles or changes in terrain. By leaning with the rider, the passenger helps to keep the motorcycle upright and reduces the risk of tipping over, especially during sharp turns or sudden stops. Holding on to the motorcycle seat or sitting as far back as possible does not promote effective weight distribution, and can lead to potential loss of control. Furthermore, a passenger never holding on to the rider creates an unsafe situation, as they might not be able to maintain their balance, and this can increase the likelihood of accidents. Overall, synchronizing movements between the rider and the passenger is crucial for a safe riding experience.
