A driver extends their left arm, bent and pointing straight up. What is their intention?

When a driver extends their left arm bent and pointing straight up, they are signaling their intention to make a right turn. This hand signal is a traditional and universally understood method of indicating a right turn to other drivers and pedestrians. Proper signaling with hand positions is essential for safe driving, as it communicates to others what actions the driver plans to take, thereby helping to prevent confusion and potential accidents. In this context, it is important for all drivers to know and recognize these signals to maintain road safety and ensure smooth traffic flow.
