When is it valid to use hand signals while driving?

Using hand signals while driving is valid when making turns or stopping. This method of communication ensures that other road users, including pedestrians and cyclists, are aware of your intentions on the road. Hand signals serve as a visual indicator, especially in situations where the vehicle's turn signals may not be easily visible, or in scenarios involving older vehicles that may lack modern signaling technology.

Hand signals enhance safety by clearly communicating your actions. For instance, extending your arm horizontally indicates a left turn, while an upward arm signal indicates a right turn. A downward arm gesture signifies a stop. This traditional signaling method complements the use of vehicle indicators and is especially important in conditions where visibility may be compromised.

While there are other situations where signaling is crucial, such as driving slowly or during nighttime, those scenarios do not specifically address the primary purpose of hand signals. Thus, the correct context for utilizing hand signals is indeed when turning or stopping.
