How to Check Driver's License Test Score Information?

What does optional license plate prefix mean?

Optional license plate prefix refers to the ability of motor vehicle owners to choose their own license plate numbers. Self-selected vehicle license plate numbers: There are two forms: one is online selection, and the other is selection at the vehicle management office. Online selection is divided into random selection and self-selected numbering. For online selection, only combinations of numbers + letters + numbers can be chosen. Owners can opt for random selection. For self-selected numbering, the number segments must have been released for more than 7 days. Each self-selection allows for up to five number combinations, with a total of 20 self-selection opportunities. Once a self-selected license plate number is chosen, it cannot be changed. Points to note when selecting a license plate number: After selecting a number online, it must be processed at the local vehicle management office within three days. If this period is exceeded, the selected number will automatically become invalid. Documents required for new vehicle number selection: original ID card, ID card copy, original vehicle qualification certificate, compulsory insurance policy, car purchase invoice, car purchase qualification certificate, and original registration form.

What is the working principle of an oxygen sensor?

An oxygen sensor utilizes a ceramic sensing element to measure the oxygen potential in a vehicle's exhaust pipe. Based on the principle of chemical equilibrium, it calculates the corresponding oxygen concentration to monitor and control the air-fuel ratio of combustion, ensuring product quality and compliance with exhaust emission standards. Relevant information about oxygen sensors is as follows: 1. The oxygen sensor operates on the Nernst principle. Its core component is a porous ZrO2 ceramic tube, which is a solid electrolyte with porous platinum (Pt) electrodes sintered on both sides. 2. At a certain temperature, due to the difference in oxygen concentration on both sides, oxygen molecules on the high-concentration side (inside the ceramic tube) are adsorbed on the platinum electrode and combine with electrons (4e) to form oxygen ions O2-, making this electrode positively charged. The O2- ions migrate through oxygen ion vacancies in the electrolyte to the low-oxygen-concentration side (exhaust gas side), making that electrode negatively charged, thus generating a potential difference.

What grade of gasoline is best for the Bin Yue?

Bin Yue uses a turbocharged engine, and it is better to use 95-octane gasoline. High-grade gasoline burns more completely and reduces carbon deposits. Here is some extended information about gasoline: 1. The English name for gasoline is Gasoline (US)/Petrol (UK). It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Its main components are C5–C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance). 2. Gasoline is produced and sold by grade, with the grade specifications defined by national gasoline product standards and related to different standards. Currently, China's National (IV) gasoline grades include three types: 90, 93, and 97. National (V) grades are 89, 92, and 95 (with 98 available in the appendix). Gasoline grades are classified by octane number. For example, 97-octane gasoline refers to a fuel with anti-knock performance equivalent to a mixture of 97% isooctane and 3% n-heptane. The higher the grade, the better the anti-knock performance.

How long after drinking half a glass of baijiu can you drive?

It is recommended to wait 24 hours after drinking half a glass of baijiu before driving. The alcohol in the human body generally takes 10 to 24 hours to dissipate, so some drivers who drink at night and drive the next day may still be found to be driving under the influence. Types of drunk driving: If the blood alcohol content of a vehicle driver is greater than or equal to 20mg/100mL but less than 80mg/100mL, it is considered drunk driving, which is illegal. If the blood alcohol content of a vehicle driver reaches or exceeds 80mg/100mL, it is considered drunk driving, which is a criminal offense. Penalties for drunk driving: For drunk driving, the driver's license will be suspended for one to three months, and the driver will be fined and receive 6 demerit points. The legal penalties for drunk driving of commercial vehicles are more severe, with a three-month suspension of the driver's license, a fine, and 12 demerit points. For drunk driving, the traffic management department of the public security authority will restrain the driver until sober, revoke the driver's license, and pursue criminal liability. The driver will not be allowed to obtain a driver's license again for five years. For drunk driving of commercial vehicles, the traffic management department of the public security authority will restrain the driver until sober, revoke the driver's license, pursue criminal liability, and the driver will not be allowed to obtain a driver's license again for ten years. After regaining the driver's license, the driver will not be allowed to drive commercial vehicles.

How Many Chances Are There for Each Subject 2 Test?

For the Subject 2 test, if the initial attempt is unsuccessful, one retake is allowed. If the applicant does not take the retake or fails it again, the current test session ends, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of rescheduled attempts for Subject 2 and Subject 3 (road driving skills test) must not exceed five. If the fifth rescheduled test is still unsuccessful, the passing scores of other subjects already taken will be invalidated. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: ① For applicants of large buses, trailers, city buses, medium buses, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for large vehicles (A1, A2, A3, B1, B2) include: pole test, hill start and stop, parallel parking, single-plank bridge crossing, curve driving, right-angle turn, narrow gate passage, continuous obstacle crossing, bumpy road driving, narrow road U-turn, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling. The test items for small vehicles (C1, C2) include: reverse parking, parallel parking, hill start and stop (canceled for C2), right-angle turn, and curve driving (commonly known as S-curve). These five items are mandatory (some regions include a sixth item: highway toll card collection).

What is Green-Max Tire?

Green-Max tire is a product under Linglong Tire, named GREEN-Max Green Drive, manufactured by Shandong Linglong Tire Co., Ltd. It is an ultra-high-performance tire with excellent wet grip performance and low noise. It features the following technical characteristics: high handling performance, excellent drainage capability to effectively reduce hydroplaning, superior stability, comfortable ride experience, and suitability for high-end sedans and sports cars. Shandong Linglong Tire Co., Ltd. is a specialized, large-scale, and technology-driven private tire manufacturing enterprise established on June 6, 1994, in Zhaoyuan City, Shandong Province. The company's tire brands are widely used in commercial vehicles, passenger cars, construction machinery, etc., and have successfully entered the global supply chain of renowned automotive brands such as Audi, Volkswagen, General Motors, and Ford. It ranks among the top 3 tire manufacturers in China and the top 20 globally. Linglong Group's tire products have obtained certifications such as CCC, DOT, ECE, GCC, INMETRO, and LATU. The quality management system is certified by ISO9001 and TS16949, while also meeting ISO14001 environmental management system certification, GB/T28001 occupational health and safety management system certification, and has established an SA8000 social responsibility management system. Green-Max tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high/low-temperature effects during operation. Therefore, they must possess high load-bearing performance, traction performance, and cushioning performance, along with high wear resistance and flex resistance, as well as low rolling resistance and heat generation. They directly contact the road surface and work with the vehicle suspension to mitigate impacts during driving, ensuring excellent ride comfort and smoothness. They also ensure good adhesion between the wheels and the road, improving the vehicle's traction, braking, and off-road capability while bearing the vehicle's weight. Linglong Tire Maintenance Methods: Enhance awareness of tire safety and inspect tires regularly. Periodically correct wheel balance. Unbalanced wheels can cause high-frequency oscillations during high-speed driving, leading to uneven tire wear. Rotate tires regularly. To maintain even wear across all tires on the same vehicle, perform tire rotation every 5,000 kilometers. For daily use of Linglong tires, pay attention to the following: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear from driving, the tread grooves gradually become shallower. If the tread is worn flat, it loses its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks may also pose a risk of tire blowouts during high-speed driving. Additionally, promptly remove stones lodged in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool tires. In hot weather or during high-speed driving, tires are prone to overheating, and tire pressure may increase. In such cases, park to allow natural cooling. Never release air to reduce pressure or splash water to cool the tires, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear caused by dragging between the tires and the road.
