Because different car models vary, the number of turns required to straighten the wheel also differs. Here are some precautions for backing into a parking space: 1. Backing from the left side: When reversing, try to choose the left side for backing in, as it allows for better visibility. During the reversing process, first check behind you, then pay attention to the side mirrors. 2. Observe the rear situation: Before reversing, always check the rear situation, estimate the reversing path, and determine whether the front of the car might hit any obstacles. Especially when turning the steering wheel significantly, the turning radius of the front wheels is larger than that of the rear wheels, causing the front of the car to swing outward more noticeably. Be extra careful to avoid scraping the front of the car.

As a beginner who just started learning to drive, I understand the confusion about how many turns to make when straightening the steering wheel during reverse parking. Typically, when you turn and reverse, such as turning the wheel fully to the left, the standard correction requires turning the steering wheel about 1.5 turns to the right to align the car straight. However, the exact number of turns depends on the vehicle: compact cars may require around 1.5 full turns, while SUVs might need over 2 turns. It's recommended to test your own car in an open space first. Don't just memorize numbers; practice is key. Find an empty parking spot to practice: while reversing, check the side mirrors, align the rear of the car with the parking space boundary, then slowly turn the steering wheel back to center while observing if the car body tilts and making minor adjustments. Try a few times, and you'll develop a feel for it. Safety first: maintain low speed when reversing, and practice with the handbrake engaged to avoid accidents. Remember, every car is different—my first practice session nearly resulted in a scrape due to incorrect turns, but I got familiar through repeated attempts. Overall, the key to straightening the wheel lies in smooth movements and observation—don't rush.

Having driven for over a decade, my experience with the number of turns to straighten the wheels when reversing into a parking space is that it varies and isn't fixed. Generally, the theory suggests that turning the steering wheel to full lock (e.g., left turn) is 1.5 turns, and straightening requires turning back 1.5 turns to center. However, in actual driving, I never count the turns; instead, I judge based on the car's position. When reversing, once the rear of the car starts entering the space and I feel it's almost straight, I gradually turn the steering wheel back. Watching the mirrors is more important than memorizing numbers, as different cars vary greatly in the number of turns—my sedan takes 1.5 turns to full lock, while my friend's truck takes two and a half. I advise beginners not to obsess over this; the key is to control the speed and go slowly, checking if the car is properly aligned after straightening and making minor adjustments by moving forward or backward if needed. Reversing is a skill that comes with practice; the more you drive, the more naturally it comes to you. Safety should always take precedence over precise turn counts.

From a mechanical perspective, the steering wheel typically has about 540 degrees of full rotation, with a full lock to one side being approximately 270 degrees or 1.5 turns. When reversing into a parking space and needing to straighten the wheels, you should turn the wheel the same number of turns in the opposite direction to center it. For example, after completing a left-turn reverse, turn the wheel 1.5 turns to the right to resume straight driving. However, this is not a rigid rule; actual parking angles may vary, requiring slightly more or less turning. It's advisable to perform a simple test before starting: on a straight road, turn the steering wheel fully left and right, counting and noting the turns. During reversing, combine this with feedback from the vehicle body: perform the straightening action smoothly to avoid sudden turns that can cause tire wear. With a few practices, you'll be able to estimate the proportion without rigidly relying on formulas.
