Final answer:
Hand signals should be used in addition to turn signals when the turn signal is not clearly visible or when there is a risk of misinterpretation. For example, in heavy traffic or when a vehicle's turn signal is malfunctioning or not working, using hand signals can help communicate the intended actions to other drivers and pedestrians.
Step-by-step explanation:
Hand signals should be used in addition to turn signals when the turn signal is not clearly visible or when there is a risk of misinterpretation. For example, in heavy traffic or when a vehicle's turn signal is malfunctioning or not working, using hand signals can help communicate the intended actions to other drivers and pedestrians.
Another situation where hand signals can be useful is when riding a bicycle. Cyclists may not have turn signals on their bikes, so using hand signals can help indicate their intended direction to drivers and other cyclists.
Finally, in emergency situations where immediate actions need to be communicated, such as when a vehicle is about to break down or stop abruptly on the road, using hand signals in addition to turn signals can provide clear and instant communication to other road users.
