At which dashed line should you straighten the wheel during parallel parking?

[Tricia]

When the third dashed line appears in the left rearview mirror during parallel parking, you can straighten the steering wheel. Relevant information is introduced as follows: Parallel parking is a part of the second subject in the driver's license test. Parallel parking is becoming increasingly common in urban areas, especially when parking spaces in formal parking lots are in short supply. Many places have designated parking spaces on both sides of the streets, creating "parallel parking spaces." In the past, parallel parking involved using four poles placed on the ground to symbolize the four corners of the parking space. One of the criteria for successful parking was whether the vehicle could enter the space without touching these four poles. After the implementation of the new traffic regulations, parallel parking no longer uses poles; instead, all boundaries are marked with ground lines. For students learning to drive with a C1 license, the length of the parallel parking space is 1.5 times the vehicle's length plus 1 meter. Drive the vehicle to a position parallel to the parking space, then reverse into the space without any pauses. As long as the vehicle is parked within this range without crossing the boundary lines, it is considered a pass.
