What percentage of overload is there when an 11-seater car carries 7 people?

An 11-seater car carrying 7 people exceeds the load limit by more than fifty percent. Below is extended information on the hazards of vehicle overloading: Shortens the vehicle's service life: The manufacturing of vehicles is based on technical data, and the load limit is no exception. Overloading alters the original design data, such as loosening rivets, causing fastening screws to fall off, welding points to break, and the overall frame to deform. Overloading reduces the vehicle's lifespan and accelerates the aging of rubber and plastic components. Accelerates tire wear and deformation: Vehicle tires are designed and produced based on the total weight of the vehicle, with a considerable safety factor. However, when a vehicle is overloaded, the tires bear excessive weight and deform. Increased friction also shortens tire life. Studies show that a 20% overload reduces tire life by 30%, and a 40% overload shortens it by 50%. Reduces braking performance and increases the non-safety zone distance: Many factors affect a vehicle's braking distance, with changes in load directly influencing the braking distance. During braking, the load shifts forward, increasing the load on the front wheels and decreasing it on the rear wheels. This alters the ground adhesion and consequently the braking distance. A fully loaded vehicle decelerates slower than an empty one. Tests prove that at 30 km/h, for a heavy vehicle weighing over 3 tons, each additional ton of weight extends the braking distance by 0.5-1.0 meters. Overloaded vehicles, due to increased inertia, have even longer braking distances. The extended non-safety zone distance often creates unexpected psychological pressure on the driver, leading to accidents.
From a safety perspective, I have always been concerned about vehicle overloading. For example, squeezing 11 people into a 7-seater is about 57% overload, meaning four extra people are sitting in the car, which immediately skyrockets the danger level. The vehicle's center of gravity will be severely offset, especially during turns or sudden braking, drastically reducing stability and increasing the risk of rollovers or skidding. Not to mention, in emergencies, passengers in the back may be thrown out, and the effectiveness of airbags is significantly diminished. I’ve personally witnessed such accidents on the road, where the owner tried to save trouble by cramming people in, only to end up with accelerated tire wear, damaged suspension systems, and repair costs far exceeding any savings. Always remember: safety first. It’s better to make an extra trip or arrange for an additional vehicle than to take risks for temporary convenience. Regularly check your vehicle’s load limit and develop disciplined habits to ensure everyone travels safely.
