Final answer:
If electronic turn signals are not working, hand signals can be used. These include raising the left arm upwards for a right turn, extending it straight for a left turn, and lowering it to indicate stopping or slowing down.
Step-by-step explanation:
The correct answer is hand signals can be used to communicate with other drivers if electronic turn signals are not working. It is important for drivers to know these manual signals as a backup communication method. Typically, there are three hand signals recognized for road use:
- Raising your left arm upwards indicates a right turn.
- Extending your left arm straight out the window signals a left turn.
- Lowering your left arm downwards indicates that you are coming to a stop or slowing down.
Even when electronic signals fail, these hand signals are universally understood and can help prevent accidents and improve road safety.
When electronic turn signals are not working, drivers can use hand signals to communicate with other drivers. Hand signals involve extending the arm out of the window and using specific movements to indicate turns or lane changes.
For example, to indicate a left turn using hand signals, the driver extends the left arm fully out of the window and points it straight left. To indicate a right turn, the driver extends the left arm out of the window and bends the forearm upward at a right angle.
