The function of a seat belt is to instantly tighten and secure the loose belt when a vehicle collision occurs or emergency braking is applied, preventing secondary collisions by firmly restraining the occupant in the seat. If the tightening force of the seat belt exceeds a certain limit, the force-limiting device will appropriately release the belt to maintain stable chest pressure. Methods for using seat belts: 1. The breaking load indicators for the belt, rope, and metal fittings; 2. The waist belt must be a single piece, with a width of 40 to 50mm and a length of 1300 to 1600mm; 3. The protective waist belt should be no less than 80mm in width and 600 to 700mm in length; 4. The safety rope diameter should be no less than 13mm.

What does B10 life of a vehicle mean?

B10 life is defined as the operating time point of a product. After the product reaches this time point, it is estimated that 10% of the products will experience failures. Engine life: For automotive products, B10 is generally used to indicate the reliability of a vehicle. Initially, B10 was applied to bearings, where 'B' stands for the first letter of 'Bearing', and '10' represents ten percent. An engine's B10 life reaching 1 million km is specific to that particular engine and does not have a concrete standard. This means that 90% of such engines can operate up to 1 million km. Purpose of B10 life: B10 life was originally used to describe the reliability and lifespan of bearings. Through long-term usage, it was observed that the reliability of bearing products gradually declines over time. For example, if a batch of 100 bearings starts operating simultaneously, after prolonged operation, the bearings will enter a period of high failure rates. Beyond a certain time point, almost all of these 100 bearings will begin to fail.

Why Do Some Sedans Have Yellow License Plates?

The reasons why some sedans have yellow license plates include exceeding length limits, meeting weight requirements for yellow plates, or being classified as special vehicles. The specific reasons are as follows: Exceeding Length Limits: If the vehicle's body length exceeds 6 meters, it requires a yellow license plate. A sedan with a yellow plate indicates that its body length is too long to meet the blue plate standards for sedans, thus necessitating a yellow plate. Meeting Weight Requirements for Yellow Plates: Vehicles with a total mass of 4.5 tons (inclusive) or more, or those designed to carry 20 passengers (inclusive) or more, must display yellow license plates. Special Vehicles: Sedans used by driving schools, taxis, and other commercial vehicles are required to have yellow license plates. Additionally, yellow-plated vehicles need an operating permit and must undergo quarterly inspections. Furthermore, yellow-plated vehicles require a special permit to drive in urban areas.

What is the Three Touches in Subject 3?

The "Three Touches" in the Subject 3 driving test refer to: touching the sensor of the center rearview mirror, the sensor of the left rearview mirror, and the sensor under the seat, while adjusting the seat properly. Below are some tips for the Subject 3 test: 1. Follow the instructions: Listen carefully to the voice prompts during the Subject 3 test and follow them accordingly. Remember not to perform any actions before the voice prompt ends; always wait until the prompt is complete before proceeding. 2. Pay attention to special zones: In many areas, the voice prompts no longer remind candidates of special zones such as school areas, bus stops, and crosswalks. However, candidates must perform corresponding deceleration or yielding actions based on the project signs and road markings. For school zones, apply the brakes within 10 meters of the sign, keeping the speed below 30 km/h. For bus stops, apply the brakes within 10 meters of the sign, keeping the speed below 30 km/h. For crosswalks, apply the brakes to decelerate within 30 meters before the crossing, and stop to yield if pedestrians are passing.
