To signal a right turn using hand signals, you should do which of the following?

Answer: C — Point your left arm upward

To signal a right turn using hand signals, raising your left arm upward is the correct method. This action indicates to other drivers and pedestrians that you intend to make a right turn. The upward position of the arm is widely recognized as a standard hand signal for turning right, making it clear and easily understandable to those observing your movements. In contrast, pointing your left arm straight out typically indicates a left turn, while pointing your left arm downward is a signal for stopping or slowing down. Waving your arm back and forth does not convey a specific turn signal and could create confusion among other road users. Therefore, raising your left arm upward is the proper and recognized way to indicate a right turn when using hand signals.
