What does a driver indicate with a hand signal showing the hand up in the air towards the left with fingers pointing up?

When a driver signals with their hand up in the air towards the left with fingers pointing up, they are indicating a right turn. This hand signal is part of the standard practices for communicating intentions to other road users when signaling devices, such as turn signals, might not be working or when the driver prefers to use a manual signal. Proper use of hand signals is crucial for ensuring safety on the road, as they provide clear communication about a driver's upcoming actions.

In this case, raising the hand with fingers extended upward is universally recognized as the signal for making a right turn. It allows other drivers and pedestrians to anticipate the movement and adjust accordingly. This is an important aspect of road sharing, ensuring that everyone is aware of each other's intentions.
