How much overload is there when a 5-seater car carries 9 people?
2 Answers
5-seater car carries 4 more people than its capacity. According to legal regulations, driving a commercial passenger vehicle with passengers exceeding the approved number by less than 20%, or driving other passenger vehicles with passengers exceeding the approved number by more than 20% will result in a six-point penalty and a fine. Increased risk of rollover: The more overloaded passengers there are, the more the vehicle's center of gravity changes, especially when turning, making the vehicle more prone to rollover. Reduced braking performance: Inertia is related to the mass of an object. When braking, the vehicle relies on resistance to stop. The more overloaded the vehicle is, the greater its inertia, making it harder to stop during braking compared to normal conditions.
I've seen quite a few cases where a 5-seater car carries 9 people. Actually, the overload calculation is simple: designed capacity is 5 people, carrying 9 means 4 extra. The overload ratio is (9 minus 5) divided by 5 multiplied by 100%, which equals 80%. This means the vehicle's original capacity is severely exceeded, easily leading to excessive tire pressure or brake failure. Last time I helped a friend repair his car, the tire burst due to similar overloading, costing over a thousand in repairs. More seriously, overloading puts all passengers at greater risk, especially when turning as the car becomes unstable, and even slight speed increases on highways can cause loss of control. If you encounter this situation, I strongly recommend pulling over immediately and switching transportation - don't gamble with lives.
