How many points will be deducted for overloading 2 people in a 5-seater car?

A 5-seater car overloaded with 2 people is considered to exceed 20% of the capacity, resulting in 3 penalty points and a fine. For non-commercial small passenger vehicles, exceeding the approved passenger capacity by less than 20% results in 2 penalty points and a fine, while exceeding 20% or more results in 3 penalty points and a fine. Below are the hazards of overloading: Shortens the vehicle's lifespan and accelerates component aging: Overloading alters the original design specifications. For example, it can cause rivets to loosen, 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: Car tires are designed and manufactured based on the vehicle's total weight, with a considerable safety margin. However, when the vehicle is overloaded, the tires bear excessive weight and deform. Increased friction also shortens tire lifespan. Tests show that overloading by 20% reduces tire lifespan by 30%, while overloading by 40% reduces it by 50%. Accelerates engine damage: Overloading causes significant damage to the engine. The increased load leads to insufficient power. Prolonged low-speed driving causes the engine to overheat, exacerbating component damage. It also increases fuel consumption and transportation costs. Heavier steering and increased centrifugal force affect vehicle handling: Overloading increases centrifugal force during turns, reducing driving stability and increasing the risk of accidents. Reduces braking performance and increases unsafe stopping distance: Many factors affect braking distance, and changes in vehicle load directly influence it. When a loaded vehicle brakes, the load shifts forward, increasing the load on the front wheels and reducing it on the rear wheels. This alters ground adhesion and consequently changes the braking distance. A fully loaded vehicle decelerates slower than an empty one. Shortens leaf spring lifespan and reduces vehicle maneuverability: Overloading places excessive stress on leaf springs, causing continuous rebound during operation, which shortens their lifespan. Excessive load also lowers the vehicle body, reducing ground clearance and the vehicle's ability to pass obstacles.

How Many Years Should a Car Be Driven Before Scrapping?

Automobiles are categorized into private cars and commercial vehicles, and the number of years before scrapping depends on the type of vehicle, as detailed below: Regulations for scrapping private cars: For 5-seat family sedans and 7-seat SUVs, as well as non-commercial small and mini vehicles, there is no usage lifespan limit. However, when the normal driving mileage reaches 600,000 kilometers, the state will guide the scrapping process. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial sedans, and wheeled special-purpose machinery vehicles also have no usage lifespan restrictions. Common regulations for scrapping commercial vehicles: Small and mini taxi passenger cars have a scrapping lifespan of 8 years, medium-sized taxi passenger cars 10 years, and large taxi passenger cars 12 years. Public transport passenger cars have a scrapping lifespan of 13 years, while other small and mini commercial passenger cars have a scrapping lifespan of 10 years, and large and medium-sized commercial passenger cars 15 years. Mini commercial trucks have a scrapping lifespan of 8 years, while light and large commercial trucks have a scrapping lifespan of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out and submit one copy of the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form," stamped with the owner's seal; Apply at the registration and acceptance counter. For vehicles that have reached the scrapping lifespan, a "Vehicle Scrapping Notice" will be issued. For vehicles that have not reached the scrapping lifespan, the motor vehicle inspection counter will determine whether they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if applicable; The owner can choose a qualified recycling company to dismantle the vehicle by presenting the "Notice"; The recycling company will dismantle the vehicle and take photos after verifying the "Notice." The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut; The owner must submit the "Change Form," "XX Province Vehicle Renewal Technical Appraisal Form," "Scrapped Vehicle Recycling Certificate," and photos of the dismantled vehicle to the motor vehicle inspection counter for verification and signature. The license plates and certificates will be reclaimed, and the scrapping registration will be processed according to regulations after approval.

What Type of Fire Extinguisher Should Be Used in Cars?

Types of fire extinguishers used in cars include dry powder fire extinguishers, carbon dioxide fire extinguishers, and water-based fire extinguishers. Below are detailed introductions: Commonly used fire extinguisher: The most commonly used is the dry powder fire extinguisher. According to the type of dry powder extinguishing agent filled, it can be divided into ordinary dry powder fire extinguishers and ultra-fine dry powder fire extinguishers, mainly used to extinguish initial fires of flammable liquids such as petroleum and organic solvents, combustible gases, and electrical equipment. Usage specifications of dry powder fire extinguishers: Before use, fully invert and shake the extinguisher several times to ensure the dry powder inside is loosened; pull out the safety pin, hold the nozzle with your hand, and aim the extinguisher nozzle at the base of the flame; press the extinguisher's handle forcefully, at which point the dry powder will spray out from the nozzle.

What is the purpose of the 12V 120W in a car?

The purpose of the 12V 120W in a car is to externally connect electrical devices such as car phones, portable DVDs, and mobile phone chargers. A single socket can provide 12V voltage. It serves as an interface to supply power to electrical devices outside the vehicle, with an output voltage of 12V, while the current varies depending on different vehicle models. The 12V car power source can support electrical devices up to 120W. Additional information about the car power source is as follows: 1. 12V vehicle system: The battery voltage should be around 13V when unloaded, and no less than 11V under load is considered normal. Below this voltage, starting the vehicle may become difficult. 2. 24V vehicle system: The battery voltage should be around 26V when unloaded, and no less than 22V under load is considered normal. Below this voltage, starting the vehicle may become difficult.
