Final answer:
If electronic turn signals are not working, drivers can use hand signals to indicate their intent to turn or stop to other drivers. There are specific hand signals for left and right turns and for indicating a stop or slowing down.
Step-by-step explanation:
If electronic turn signals are not working, hand signals can be used to communicate with other drivers. By extending the arm and hand out the driver's side window, a driver can indicate their intent to make turns or lane changes. It's important to know the proper hand signals:
- To signal a left turn, extend the left arm straight out from the side of the vehicle.
- For a right turn, place the left arm out the window bending upward at the elbow (or using the right arm straight out in regions where this is legal).
- To indicate slowing down or stopping, extend the left arm out and downward from the driver’s side.
Remember, hand signals should be used with caution and clear intent as they are not as instantly recognizable as electronic turn signals and may be interpreted differently in various regions.
