If your vehicle's directional signals fail, what should you use until they can be repaired?

Using hand signals when your vehicle's directional signals fail is essential for communicating your intentions to other drivers. Hand signals provide a clear and visible means to indicate your turn or lane change, which promotes safety on the road.

When you're unable to use electronic signals, hand signals are universally recognized and understood. For example, extending your left arm straight out indicates a left turn, while bending it at a right angle upwards indicates a right turn. These signals allow you to convey your maneuvers effectively to surrounding traffic, helping to prevent misunderstandings that could lead to accidents.

The other options are not reliable or appropriate for signaling intentions to other drivers. Foot signals are not practical or commonly understood, and using your horn or flashing headlights may confuse other drivers rather than clarify your intentions.
