How can you tell if a cyclist is preparing to turn?

Answer: B — They may signal with their arms or position themselves to one side of the lane

A cyclist preparing to turn often does so by signaling their intention with their arms or adjusting their position within the lane. When cyclists extend their arms, it indicates the direction they plan to take, similar to how drivers use turn signals. Moreover, cyclists may move towards one side of the lane as they prepare to navigate a turn, indicating to drivers that they are planning to change direction. Recognizing these cues is essential for maintaining safety on the road, allowing drivers to anticipate the cyclist's movements and respond accordingly. The other choices do not accurately reflect the common behaviors of cyclists when preparing to turn. For instance, speeding up is not a reliable indication of a turn, as cyclists typically maneuver at a consistent speed while signaling. Swerving can happen for various reasons, such as avoiding obstacles, but it does not specifically indicate an intention to turn. Finally, stopping at the curb is not a standard action for signaling a turn; cyclists may choose to slow down or stop for other reasons, such as traffic signals or road conditions. Understanding these behaviors helps in fostering safer interactions between drivers and cyclists.
