What is a key reason for avoiding sudden lane changes?

Answer: A — It can cause instability and increase the risk of a crash

Avoiding sudden lane changes is crucial primarily because they can lead to instability and heighten the risk of a crash. When a motorcyclist abruptly changes lanes, it can disrupt the balance and control of the motorcycle, especially if the change occurs at high speeds or in heavy traffic. In addition, other drivers may not anticipate such movements, increasing the likelihood of collisions. Maintaining predictable and smooth lane changes allows both riders and drivers to react appropriately, reducing the overall chance of an accident. Therefore, prioritizing safety through controlled lane changes contributes to a safer riding environment.
