What is the best way to indicate a right turn to other drivers?

To indicate a right turn to other drivers, extending your left arm bent upward is the correct method. This hand signal clearly communicates your intention to turn right. The upward bend of the arm resembles a "L" shape and is universally recognized by other drivers and cyclists on the road as a right-turn signal.

Using this hand signal is particularly important in situations where brake lights may not be visible, such as when you're driving a vehicle with tall rear ends or in adverse weather conditions where visibility is reduced. Proper signaling enhances road safety by ensuring that surrounding vehicles understand your movements.

Other options, such as extending the left arm straight out, which signifies a left turn, or extending the right arm straight out, which typically communicates a right turn in some interpretations, are not the most common or recognized hand signals for indicating a right turn. Keeping both hands on the wheel at the 10 and 2 positions is crucial for control of the vehicle but does not serve to communicate your intentions to other drivers.
