How to Check if the Car Body is Parallel to the Line?

Inaccurate rearview mirror adjustment may lead to a significant difference between what you see and the actual situation. Generally, aligning the lower edge of the rearview mirror with the position of the rear door handle is sufficient. You can move your head to the central area inside the car, then adjust the right rearview mirror outward until you can no longer see your right fender in the mirror. There are two approaches to steering wheel adjustment. One is to steer towards the side that appears wider, where 'wider' refers to the rear of the car. Looking at the right rearview mirror, if the rear of the car appears wider, steer to the right. This will make the right side of the rear move closer to the right parking line. This method is commonly used to align the car body with the yellow line.
When driving or parking, my method for judging whether the car body is parallel to the ground lines is quite simple: first, slow down or stop, then observe through the side mirrors whether the lines align with the edges of the car body. If the lines in the mirror are straight and flush with the car's edges, it means they are parallel; if they are skewed or at an angle, slight steering adjustments are needed to correct it. Another effective technique is to find reference points, such as aligning the front of the car or the wheels with the ends of the lines—the wheels should directly face the starting or ending points of the lines. This isn't just about aesthetics; a misaligned car body can lead to uneven tire wear, long-term damage to the suspension system, or even door scrapes when parked roadside. Personally, I like to practice mirror alignment in parking lots—it's intuitive and safe, especially for beginners, helping to avoid awkwardly angled parking. Once it becomes a habit, you can also sense changes in the vehicle's posture, boosting overall driving confidence.
When parking to check for alignment, I would advise learners to start with the basics: observe whether the lines in the rearview mirror align with the car's boundaries. If they are not parallel, make slight adjustments to the steering wheel until the two appear flush. Reference points are also very useful, such as aligning the front of the car with the end of a ground line, which ensures the entire vehicle is not skewed. Patience is key during this process, and practice is essential; incorrect adjustments may cause the car to veer, increasing the risk of accidents. For everyday driving, the importance of proper vehicle alignment cannot be overstated, as it affects tire lifespan and fuel efficiency—parking at an angle increases wear on one side. Having taught many people, I emphasize slow-motion practice and visual focus to help develop automatic responses and reduce unnecessary trouble.
As a new driver, I used to park at ridiculous angles. A friend taught me a simple trick: check if the wheels align with the ground markings—if they point straight at the line ends, the car body is basically parallel. I often practice in my neighborhood, sometimes sticking my head out the window to check overall alignment. Crooked parking wears tires faster, so I practiced until I got it right. Now before parking, I always take an extra glance at external lines to ensure that straight feeling.
