Do I need to use turn signals in an S-curve?

[JosiahFitz]

In Subject 2 of the driving test, turn signals are not required for S-shaped curves. Here is some additional information: 1. Situations in Subject 2 where turn signals are required: Turn on the left turn signal before starting the vehicle. Turn on the left turn signal before starting after stopping on the slope. Turn on the left turn signal before exiting the parallel parking space. 2. Operation essentials: Before entering the "S"-shaped curve, reduce speed and enter in first or second gear, choosing an appropriate route and speed to pass through. After entering the "S"-shaped curve, the vehicle should enter along the right side of the road (about 1 meter from the left edge), maintaining a steady low speed. Keep a distance of about 0.5 meters from the right side of the road and make appropriate steering adjustments (leaving enough distance for the inner wheel difference on the left side).
