What should you anticipate about a motorcyclist's movements?

Anticipating a motorcyclist's movements is crucial for maintaining safety on the road. Motorcyclists have the flexibility to maneuver their bikes in a way that larger vehicles cannot, which often involves using the entire lane. This can include weaving through traffic, changing positions within their lane to avoid road hazards, or making sudden moves to maintain balance or regain control.

Motorcycles are narrower than cars, allowing them to occupy spaces that might not be as accessible for standard vehicles. Additionally, conditions on the road can require sudden adjustments; for example, a motorcyclist may need to shift their position unexpectedly due to gravel, potholes, or other road conditions. Thus, drivers should be prepared for unexpected movements from motorcyclists to enhance safety for themselves and the riders.

The other options suggest behaviors that may not accurately reflect the typical actions of a motorcyclist. Riding in a straight line or always staying in the right part of the lane misrepresents the flexibility and adaptability of motorcycle operation. While signaling turns is encouraged, it's not guaranteed that all motorcyclists will do so consistently.
