When reversing to the left into the parking space, the second full left turn of the steering wheel should occur when the left rear wheel basically aligns with the extended line of the left corner of the parking space. The entire reverse parking process can be summarized as two full turns and two straightenings of the steering wheel, making it particularly important to know the timing for full turns and straightenings. Introduction: Reverse parking has been a mandatory test item for obtaining a small car driver's license since 2013. It assesses the driver's ability to maneuver the vehicle within a confined space. Reverse parking is one of the assessment points in the driver's test, specifically the correct reversal of the vehicle into a garage from both sides while in motion. Methods: There are three most common types of reverse parking. The first is the "non"-shaped reverse parking, commonly seen in large shopping malls. The second is the roadside "one"-shaped reverse parking, also known as parallel parking. The third is the less common diagonal reverse parking. 70% of driving school students find parallel parking more challenging.

As an experienced driving instructor, I emphasize that the second full-lock steering position during reverse parking is crucial. Generally, it occurs after you've initially turned the steering wheel fully to enter the parking space and continue reversing while monitoring through the rearview mirror. When the car body becomes parallel with the parking space boundary and you see the rear wheel perfectly aligned with the rear corner of the space, immediately turn the steering wheel fully to the opposite side. This critical point varies by vehicle size – compact cars may require action at about 30cm from the edge, while larger vehicles need more distance. Always operate at low speed (under 5km/h) to avoid misjudgment. Remember to practice repeatedly in open areas to develop muscle memory; incorrect positioning can easily cause rear-end scrapes or misalignment, compromising safety. In my teaching, I repeatedly remind students of this detail to ensure smooth parking maneuvers.

As an ordinary driver with over a decade of experience, my personal observation is that the second full-lock steering during reverse parking is typically positioned using the rearview mirrors. Specifically, after the initial full-lock entry positions the car body, I gradually reverse until the rear wheels align parallel with the parking line in the side mirror or when a specific reference point (like the parking corner) comes into view—then quickly turn the steering wheel to full lock. This position is roughly when the rear wheels are about 50cm from the parking boundary. During operation, it’s important not to rush and to gently press the brake to control speed. I’ve noticed that reference points vary across different parking spaces, requiring practical adjustments. Before each reverse, I make it a habit to scan the surroundings for safety. Once familiar, parking becomes more precise, resembling a process of finding a balance point. I recommend starting with simple scenarios and gradually building up skills.

As a new driver who just got my license, my instructor emphasized teaching the second full-lock steering position when learning reverse parking. It occurs during the reversing process - after straightening out from the first full-lock turn and continuing to move backward, you immediately turn the steering wheel to full lock when observing the rear wheel approaching and aligning with the rear corner of the parking space in the side mirror. This positioning point requires repeated practice to master; initially I always turned too early or too late, resulting in crooked parking, but after over a dozen practices I've got the hang of it. The key is to watch the mirrors carefully, go slowly (under 3km/h), and maintain control. Now the operation feels much more natural, and my parking efficiency has improved significantly.
