Methods to determine if the car body is aligned: 1. While driving, when the reference lines in both side mirrors are parallel to the car body, the body is aligned; 2. When parking, observe through the rearview mirror whether the rear of the car is parallel to the road edge or parking lines; 3. After parking, if the front part of the car is perpendicular to the road edge, the body is aligned. Methods to determine if the steering wheel is centered: 1. Remember the number of turns made to the steering wheel; 2. Observe the logo on the steering wheel—each car has its brand logo. If the logo is upside down, the steering wheel is not centered; if it's upright, the steering wheel is centered; 3. Start the car and move forward. If the car deviates from the lane while moving, the steering wheel is not centered; if it moves straight, the steering wheel is centered.

People who have been driving for over a decade usually check if their car is aligned like this: glance at the relative positions of the left and right edges of the rearview mirror against the road markings or the adjacent green belt—if they're parallel, the car is straight. Beginners can roll down the window while parking to observe if the distance between the wheels and the curb is even; if one side is significantly farther than the other, the car is crooked. I prefer to slightly release the steering wheel on open roads to see which way the car drifts—when driving straight, the wheel will naturally correct itself slightly. You can also practice at red lights by aligning the dashboard with the traffic light pole ahead for accuracy. If still unsure, install a small convex mirror on the side mirror or use reference points through the corners of the windshield for assistance.

I remember when learning to drive, the instructor taught me two reference points to judge the car's alignment: first, using the bottom edge of the windshield as a ruler to check if it's parallel with the distant road edge; second, observing whether there's an angle between the road divider line and the car body in the rearview mirror. I still use this method today—it's super handy. Another trick is watching the vehicle's path when the steering wheel is straight; if it drifts, the wheel isn't properly aligned. During reversing, I more on the reversing camera guidelines—when the two lines overlap, it's good. I've made it a habit to check if the dashboard is level after adjusting direction, so I don't have to constantly worry about alignment while driving.

I'm used to a triple-check method: first, I look in the rearview mirror to see if the side lines on both sides are symmetrical and parallel, then observe whether the angles of the left and right A-pillars are equidistant from reference points ahead, and finally, I glance at the distance difference between the tires and the ground markings. The simplest way when parking is to check if the hood crease is parallel to the curb. On the highway, I on the steering wheel's feedback—if the car can go straight for about thirty meters after releasing a full turn, the alignment is generally good. Modified car enthusiasts often install level gauges, but it's unnecessary for regular family cars. The most practical approach is to drive more and build muscle memory through practice.

The most reliable method to judge vehicle alignment is combining static and dynamic references: when stationary, check if the road markings appear equidistant from both sides through the rear window, or observe if the vehicle outline is symmetrical in the reversing camera; while driving, feel for any pulling sensation in the steering wheel - misaligned bodywork causes slight drifting of steering wheels. I prefer using wiper blade nodes on the windshield as reference points to align with road markings. New drivers are advised to install blind spot monitoring systems that provide vehicle angle data. Remember to realign the vehicle when starting on slopes.

Vehicle angle alignment can be performed as follows: When parked on level ground, check if the reflections in both side mirrors are symmetrical. If the vehicle behind appears parallel, it indicates your car is properly aligned. While driving, observe whether both sides of the instrument panel are parallel to the road edges, and pay attention to whether the wheels fully straighten when the turn signal resets. During nighttime driving, use the light beam coverage as an auxiliary reference – uniform light distribution on the road surface confirms correct alignment. A highway driving tip is to check if the rear windshield edges shown in the central rearview mirror align with the horizon. These methods prove useful for daily driving.
