Should I turn on the turn signal again if it goes off during a U-turn in the driving test?

[DelEleanor]

In this situation, if the lane change operation has been completed, there is no need to pay attention to the turn signal and you can continue driving; if the turn signal has gone off and the front of the car has entered the road change, there is no need to turn on the signal again at this time, but it is still recommended to turn it on. Below is some extended information about turn signals: 1. Automatic shut-off: During the lane change process, the turn signal may go off. Every vehicle is equipped with a steering wheel motor return signal switch, which automatically turns off the turn signal when the steering wheel approaches the turn signal. For example, when returning the steering wheel, even a slight movement can cause the turn signal to automatically shut off. 2. Function of turn signals: To alert pedestrians or other vehicles of the intended turning direction, either left or right; on highways, they also indicate the direction for overtaking or merging; when both left and right turn signals flash simultaneously, it indicates that the vehicle is in an emergency situation, alerting other vehicles to be cautious.
