What does vehicle width mean?

Vehicle width refers to the distance between two planes parallel to the longitudinal symmetry plane of the vehicle, which respectively abut against the fixed protruding parts on both sides of the vehicle (excluding rearview mirrors, side marker lights, turn signal indicators, flexible mudguards, and the deformation of the part where the tire contacts the ground). Below is an introduction to related car dimensions: 1. Definition: Car dimensions refer to the regulations limiting the total height, total width, and total length of a vehicle. 2. Vehicle length: The distance between two vertical lines perpendicular to the longitudinal symmetry plane of the vehicle, which respectively abut against the outermost protruding parts at the front and rear of the vehicle. 3. Wheelbase: The distance between two vertical lines of the vehicle's longitudinal symmetry plane when the vehicle is in a straight driving position, measured from the ground contact center points of the wheels on the same side of adjacent axles. 4. Track width: On the supporting plane, the distance between the center lines of the left and right wheel tracks on the same axle (for dual wheels at both ends of the axle, it is the distance between the center lines of the left and right dual tracks).
Vehicle width refers to the distance between the widest parts of the car measured from left to right. Generally, it includes the main body structure, but whether the side mirrors are included depends on the vehicle model and measurement standards. For example, in China, many cars are labeled with a width that excludes the side mirrors for easier daily reference. Having driven many models, I find this dimension quite important because it directly affects parking convenience—a car that's too wide simply won't fit into a tight parking space and may scratch other vehicles. Measurements are usually given in millimeters, with mainstream sedans around 1800mm wide, while SUVs or off-road vehicles tend to be wider, possibly close to 1900mm, and supercars narrower for greater agility. Understanding this helps avoid trouble when choosing a car, especially in narrow alleys of old urban areas where wider cars can be a real headache. It's advisable to measure the actual dimensions when checking out a car.
For me, vehicle width represents the maximum distance between the left and right sides while driving, which significantly impacts the actual driving experience. When I first learned to drive, I neglected this aspect and ended up frequently scraping walls when turning on narrow roads. Width determines your turning radius—the wider the car, the more space it needs to make a wide turn. This becomes even more apparent when parking, as standard parking spaces are typically 2 meters wide. If your car is close to 1.9 meters wide, parallel parking becomes a bit tighter. I always check the owner's manual or official website specifications for width data, which is measured in millimeters—don't mistake it for inches. In practical terms, a wider car offers more stability on highways, reducing the risk of rollovers, but it can be a hassle in congested city traffic, making it harder to squeeze into lanes. Additionally, a wider body increases the drag coefficient, leading to higher fuel consumption. In summary, considering all these factors, choosing a car with moderate width can save you a lot of hassle, especially for beginners—avoid models that are too wide.
