How long does it take to schedule a Subject 2 driving test?

Scheduling a Subject 2 test generally takes about one week. Here are the key points to note for the Subject 2 test: 1. Reverse Parking: The main deductions for reverse parking include hitting the line, failing to enter the parking space, exceeding the time limit, and not following the designated route. After the new regulations, reverse parking now has a time limit of 210 seconds; exceeding this time results in failure. During the test, perform the right-side reverse first, followed by the left-side reverse. Not following this order will result in failure. Pay attention to maintaining a 30cm margin when parking. 2. Parallel Parking: The main deductions for parallel parking involve turn signals, maintaining a 30cm margin, and hitting the line. When entering the test area, steer right early and align the highest point of the wiper with the roadside line to adjust the 30cm margin. Remember the steps: first turn the wheel fully to the right, then straighten, then turn fully to the left, park, and turn on the left turn signal. When exiting, check the rearview mirror to avoid hitting the lines with the wheels. 3. 90-Degree Turn: The main deductions for the 90-degree turn involve turn signals and hitting the line. After entering the test area, turn on the turn signal and turn it off after the voice prompt. Incorrect use of the turn signal deducts 10 points. After entering the turn, adjust the car to maintain a 30cm margin from the line, similar to parallel parking. When turning the wheel fully, slightly release the clutch to prevent stalling or stopping midway. Straighten the car only after the rear wheels exit to avoid hitting the line.
