It is ok to drive slowly from the second gear to the right-angle turn, and it is also ok to semi-trailer, but it is not allowed to semi-trailer for a long time when you get off the road, and second gear is allowed.
I don't know what it means to stop directly and drive slowly, but you can stop there or drive slowly, as long as you don't press the line and turn signals, but I personally don't recommend wasting too much time there (the right-angle turn in the third quarter is easier than the second quarter, regardless of the outside line)
Generally, there will be no car in front to start the operation. Only one car in a lane should take the test at the same time, and it can be semi-linked from start to stop, with a considerable time difference, which is generally no problem. If there is a car ahead, don't step on the clutch, don't put in gear, and don't release the brake. If you do this, there will probably be a time limit, or you can ask the safety officer to suspend the exam (the safety officer has the right, and the preceding vehicle can do the same).
Please adopt it if it is useful.
