Which signal indicates a right turn?

Answer: B — Right arm extended upward

The indication for a right turn is communicated through the use of the right blinker, which provides a clear signal to other road users that the driver intends to make a right turn. This visual cue is critical for maintaining safety on the road, as it allows vehicles, cyclists, and pedestrians to anticipate the driver’s actions and position themselves accordingly. Using the right blinker is a standard practice that aligns with traffic laws and ensures predictable behavior on the road, which is essential for accident prevention. This specific choice highlights the importance of using turn signals to enhance communication while driving, allowing for smoother traffic flow and reducing the likelihood of misunderstandings or collisions at intersections.
