How many points can be deducted during the probationary period?

A maximum of 11 points can be deducted during the probationary period of a driver's license. Below are the relevant precautions for the probationary period: 1. Extension of the probationary period: For drivers holding licenses for large buses, tractors, city buses, medium-sized buses, or large trucks, if they accumulate 6 or more points but less than 12 points within the one-year probationary period, the probationary period will be extended by one year. If they again accumulate 6 or more points but less than 12 points during the extended probationary period, their driving qualification for the probationary vehicle type will be revoked. 2. Driving restrictions during the probationary period: During the probationary period, motor vehicle drivers are not allowed to drive public buses, commercial passenger vehicles, police cars, fire trucks, ambulances, engineering rescue vehicles, or vehicles carrying explosives, flammable and explosive chemicals, highly toxic or radioactive materials, and other hazardous items. 3. Accompanying driver requirement during the probationary period: When driving on highways during the probationary period, the driver must be accompanied by someone who has held a driver's license for the corresponding or higher vehicle type for more than three years.

What Category Does Engine Oil Belong To?

Engine oil belongs to the category of lubricants. Engines generally use three types: conventional mineral oil, semi-synthetic oil, and full synthetic oil. Based on their base oil, engine oils in the market can be divided into two categories: mineral oil and synthetic oil (vegetable oil is not considered due to its scarcity). Synthetic oils are further classified into full synthetic and semi-synthetic, with full synthetic oil being the highest grade. Here is a related introduction: 1. Mineral Oil: Mineral oil is a commonly used lubricant in the market. It is derived from the refining process of petroleum, where useful substances like gasoline and aviation fuel are distilled, and the remaining base oil is further processed. Essentially, mineral oil is inexpensive, but its service life and lubrication performance are inferior to synthetic oil, and it also causes significant environmental pollution. 2. Semi-Synthetic Oil: Semi-synthetic oil is made from semi-synthetic base oil, which is a product of refining mineral oil through hydrocracking technology. It is a blend of mineral oil and full synthetic oil in a 4:6 ratio. The purity of semi-synthetic oil is very close to that of full synthetic oil, but its cost is slightly higher than mineral oil, making it an ideal transitional product from mineral oil to synthetic oil. 3. Full Synthetic Oil: Full synthetic oil is the highest-grade oil among engine oils. It is derived from ethylene and propylene dispersed from natural gas or crude oil, which undergo polymerization, catalysis, and other complex chemical reactions to form a lubricating fluid composed of large molecules. Essentially, it utilizes the better components of crude oil, undergoes chemical reactions, and achieves the desired molecular structure under human control. Full synthetic oil has neatly arranged molecules, giving it strong resistance to external variables. Therefore, it has superior properties, such as better thermal stability, oxidation resistance, and viscosity stability, far exceeding those of mineral oil and semi-synthetic oil.

How long does it take to obtain a B2 driver's license through upgrade?

It requires more than three years. Below are the conditions for upgrading from C1 to B2: Hold a small car C1 driver's license for more than 3 years, with no full-point record in the last three consecutive scoring cycles, aged between 20 and 50 years old, no record of causing a fatal traffic accident with equal or greater responsibility; no record of drunk driving; and no revocation or cancellation of the driver's license within the last ten years. C1 is a code for a type of driver's license. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 123), C1 refers to a driver's license that permits driving small and micro passenger vehicles, light and micro cargo vehicles, as well as light and micro special-purpose vehicles. It also allows driving vehicles under the C2, C3, and C4 categories. A B2 driver's license permits driving heavy and medium-duty cargo vehicles or large, heavy, and medium-duty special-purpose vehicles. Heavy and medium-duty cargo vehicles are mainly trucks, such as the large dump trucks commonly seen on roads, which belong to the heavy truck category. Large, heavy, and medium-duty special-purpose vehicles refer to vehicles equipped with special equipment or devices, such as water sprinklers, concrete mixers, fire trucks, etc. Article 14 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" states that for first-time applicants of a motor vehicle driver's license, the permitted vehicle types include urban buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, small automatic transmission passenger cars for the disabled, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. For those who already hold a motor vehicle driver's license and wish to apply for additional permitted vehicle types, the additional types include large buses, tractors, urban buses, medium buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. Article 15 states that those who already hold a motor vehicle driver's license and wish to apply for additional permitted vehicle types must have no record of accumulating 12 points in the current scoring cycle and the most recent scoring cycle before application. For applications to add medium buses, tractors, or large buses, the following additional conditions must be met: For adding a medium bus permit, the applicant must have held a license for urban buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, or three-wheeled cars for more than three years, with no record of accumulating 12 points in the last three consecutive scoring cycles before application. For adding a tractor permit, the applicant must have held a license for medium buses or large trucks for more than three years, or a large bus permit for more than one year, with no record of accumulating 12 points in the last three consecutive scoring cycles before application. For adding a large bus permit, the applicant must have held a license for urban buses, medium buses, or large trucks for more than five years, or a tractor permit for more than two years, with no record of accumulating 12 points in the last five consecutive scoring cycles before application. Full-time driving vocational education students who have obtained a small car permit at school and have no record of accumulating 12 points in the current scoring cycle and the most recent scoring cycle before application can apply for large bus and tractor permits.

What is the real fuel consumption of the Tiggo 3?

6.7-7.9 liters/100km. Here is some relevant information about the fuel consumption of the Tiggo 3: 1. Reasons for high fuel consumption in the Tiggo 3: Damaged piston rings; inconsistent driving speeds; aging machinery; damage to the fuel tank or fuel lines. 2. Solutions for high fuel consumption in the Tiggo 3: Untimely cleaning of sludge and carbon deposits can lead to increased fuel consumption, so it's necessary to clean engine carbon deposits; damaged spark plugs can reduce ignition energy, causing uneven combustion of the air-fuel mixture, which slows down acceleration and increases fuel consumption; abnormal tire pressure can also affect fuel consumption, so it's important to check and maintain proper tire pressure; additionally, pay attention to vehicle load, replace the fuel injectors if necessary, and replace the coolant temperature sensor.
