What is the proper hand signal for a right turn?

Answer: B — Left arm raised at a 90-degree angle

The proper hand signal for a right turn involves raising the left arm at a 90-degree angle. This signal clearly indicates your intention to turn right to other drivers and pedestrians. When the left arm is raised, it creates a visible cue that is easily recognizable, especially in situations where turn signals might not be functioning or are not visible to others. Using hand signals is especially important in urban areas, where communication with other road users can help prevent accidents. The left arm raised at a 90-degree angle is a standardized signal understood by drivers and cyclists alike, promoting safety and awareness on the road. While other options present different signals, the raised left arm is specifically designated for a right turn, ensuring clarity in your intentions as a driver.
