Final answer:
If a driver's turn signals aren't working, they can use hand signals like extending the left arm for a left turn, pointing the left arm up for a right turn, and pointing the left arm down to signal stopping or slowing down.
Step-by-step explanation:
If a driver's turn signals are not working, they can use hand signals to indicate their intended maneuvers.
The most common hand signals are:
- Left Turn: Extend the left arm horizontally out of the driver's window.
- Right Turn: Extend the left arm and point the hand upwards.
- Stop or Slow Down: Extend the left arm and point the hand downwards.
By using these hand signals, the driver can communicate their intentions to other drivers on the road, ensuring safe maneuvering even when the turn signals are not functioning.
