Using hand signals is an effective alternative method for signaling when electric signals, such as turn signals or brake lights, fail to operate. Hand signals are universally recognized by drivers and can clearly communicate your intentions to other road users. For example, extending your arm out to the side indicates a left turn, while raising your arm with a bent elbow indicates a right turn. This physical method of signaling allows for clear communication and ensures safety in situations where electronic signals are not functioning.

While hazard lights can indicate a vehicle's presence or a potential hazard, they do not serve the same purpose as turn signals, which are intended specifically to indicate the driver's intention to change direction. Flashing headlights can alert other drivers but are not a reliable means for indicating turns or stops. Sounding your horn can draw attention but is not a method for signaling turns and should be used sparingly to avoid confusion or panic among other drivers. Hand signals, therefore, provide clarity and a direct means of communication essential for safe driving.
