What is the percentage of overloading when an 11-seater car carries 7 passengers?

A 7-seater car carrying 11 passengers is over 50% overloaded. Below is expanded information on the hazards of vehicle overloading: 1. Shortens vehicle lifespan: Vehicles are manufactured based on technical specifications, including load limits. Overloading alters these original design parameters. For instance: loose rivets, detached fastening screws, broken weld points, and overall frame deformation. Overloading reduces vehicle lifespan and accelerates the aging of rubber and plastic components. 2. Accelerates tire wear and deformation: Vehicle tires are designed and produced according to the total vehicle weight, with considerable safety margins. However, when a vehicle is overloaded, tires bear excessive weight and deform. Increased friction also shortens tire lifespan. Tests show that at 20% overloading, tire lifespan decreases by 30%; at 40% overloading, tire lifespan is halved. 3. Reduces braking performance and increases non-safe distance: Many factors affect vehicle braking distance, with vehicle load being a direct influencer. During braking, the load shifts forward, increasing front wheel load and decreasing rear wheel load. This alters ground adhesion and consequently braking distance. A fully loaded vehicle decelerates slower than an empty one. Tests prove that at 30 km/h, for a truck weighing over 3 tons, each additional ton extends braking distance by 0.5-1.0 meters. Overloaded vehicles, due to increased inertia, have even longer braking distances. Extended non-safe distances often create unexpected psychological pressure on drivers, leading to accidents.
I remember discussing this before during a long drive. A standard 7-seater is designed for 7 people, so if you squeeze in 11, that's 4 over the limit. Calculating the overload percentage is straightforward: divide the overload number by the normal capacity and multiply by 100%, which is (4/7) × 100% ≈ 57.14%, roughly 57%. This means it's more than half over, which is very serious. Safety-wise, the braking distance increases, turns become harder to control, and in case of an accident, the risk of injury is higher. Additionally, the vehicle's brake pads and tires wear out faster, and repair costs might exceed the fine. Legally, overloading is prohibited in many places, with fines ranging from hundreds to thousands if caught. It's best not to take the risk—just call another car or use public transport for peace of mind and safety.
