Can an A1 license drive a tractor-trailer?

According to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses': The A1 license category is for large passenger vehicles, and the permitted vehicle types are: A3, B1, B2, C1, C2, C3, C4, M. Therefore, it does not allow driving an A2 tractor-trailer. Additional information: 1. Detailed introduction to driving license categories: The Ministry of Public Security has subdivided the current three types of permitted driving categories, namely A (large passenger vehicles), B (large trucks), and C (small cars), into seven categories based on the driving difficulty and safety requirements of different vehicle types to further enhance targeted management. 2. Regulations stipulate: First-time applicants cannot directly apply for an A1 (large passenger vehicle) commercial driving license. The tractor-trailer category specifically requires an A2 license, which cannot be applied for initially. When applying for a motor vehicle driving license for the first time in a temporary residence, applicants can apply for a C-series motor vehicle driving license but cannot apply for a motorcycle license, nor can they add a motorcycle endorsement. 3. A1 license type permitted vehicles: Permitted vehicle type: Large passenger vehicles. License code: A1. Permitted vehicles and other permitted vehicle types: Large passenger vehicles A3, B1, B2, C1, C2, C3, C4, M.

Are the license plates of court-auctioned vehicles transferred together?

Court-auctioned vehicle license plates are not transferred together. The vehicle can be transferred, but the license plate cannot. When transferring the vehicle, the vehicle management office will cancel the original license plate and vehicle registration certificate, and issue new ones to the transferee. Legality of motor vehicle license plate auctions: License plate auctions are illegal and lack legal basis. The "Automobile Industry Development Policy" promulgated by the National Development and Reform Commission also stipulates that no unit may impose any non-operational service fees on automobile consumers except for the fees stipulated by the state. Vehicle license plates are public resources, not government property, and taxpayers are the true owners of the plates. Auctioning public resources should require public consent and cannot exclude the public from decision-making. Article 19 of the "Regulations on the Registration of Motor Vehicles" stipulates that for transfer registration, the current owner of the motor vehicle shall fill out an application form, submit the vehicle for inspection, and provide the following documents and certificates: Identity proof of the current owner, proof and certificate of vehicle ownership transfer, vehicle registration certificate, vehicle registration license, for customs-supervised vehicles, the "Release Certificate of Customs-Supervised Vehicles" or customs-approved transfer certificate, and for vehicles exceeding the inspection validity period, the vehicle safety technical inspection certificate and compulsory traffic accident liability insurance certificate.

What is the Function of a Roll Cage?

Roll cages are most widely used in racing cars and are a mandatory piece of equipment in official racing competitions. They serve two main purposes: protecting the driver's safety and enhancing the car body's strength and resistance to torsion. Protecting the Driver's Safety: Due to their reasonable geometric structure design, proper welding points, and qualified materials, roll cages maximize their sturdiness, ensuring the driver remains unharmed in the event of severe accidents such as rollovers. Enhancing Car Body Strength and Resistance to Torsion: In racing competitions, the car body is often stripped and fully welded to ensure its strength. The roll cage is typically welded to the car body, effectively absorbing impacts from the ground and preventing the frame from deforming. Roll cages are not suitable for family cars. However, many car modification enthusiasts install roll cages in their vehicles to achieve a cooler, more race-car-like appearance. Although they may look similar, the actual performance differs significantly. Professional manufacturing must consider welding points, angles, and materials, whereas most roll cages made by non-professionals fail to meet quality standards. In the event of an accident, these substandard roll cages can easily break, causing additional harm to the occupants.

What does 235/55r18 mean?

235/55r18 represents: 235 indicates the tire's cross-sectional width of 235mm; 55 represents the aspect ratio, which is the percentage of the tire's cross-sectional height divided by its width. A higher value means a thicker tire, lower mobility, but increased comfort; r stands for the tire type, radial tire, and 18 indicates the rim diameter of 18 inches. Below is relevant information about tire specifications: 1. Tire specifications: Tire specifications are commonly represented by a set of numbers. The first number indicates the tire's cross-sectional width, and the latter represents the rim diameter in inches. For example, 165/70R14 means a tire with a width of 165mm, an aspect ratio of 70, and a rim diameter of 14 inches for a radial tire. Some tires may include other letters or symbols with special meanings: "X" indicates a high-pressure tire; "C" stands for reinforced; "B" denotes a bias-ply tire; "-" represents a low-pressure tire. M and S are abbreviations for Mud and Snow in English, indicating that the tire is suitable for use on snowy and muddy roads. 2. Tire model: Tire model markings mostly appear as: 215/70R15. The meanings of these numbers are: 215 indicates the tire's cross-sectional width in mm; 70 is the aspect ratio, representing the ratio of the tire's sidewall height to its cross-sectional width, with 70 meaning 70%; R is the abbreviation for Radial, indicating the tire has a radial structure, and 15 is the rim's outer diameter in inches.

What Are the Effects of a Weak Car Battery?

If a car battery remains in a weak state for an extended period, the most immediate damage is excessive carbon buildup in the engine, leading to a significant drop in power. Here is some relevant information about car batteries: 1. Working Principle: A car battery uses lead plates filled with sponge-like lead as the negative electrode and lead plates filled with lead dioxide as the positive electrode, with a 22–28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, metallic lead serves as the negative electrode, undergoing oxidation to form lead sulfate, while lead dioxide acts as the positive electrode, undergoing reduction to also form lead sulfate. When charging with direct current, lead and lead dioxide are regenerated at the respective electrodes. After disconnecting the power source, the battery returns to its pre-discharge state, forming a chemical cell. A lead-acid battery is rechargeable and reusable, known as a secondary battery, with a voltage of 2V. Typically, three lead-acid batteries are connected in series to achieve 6V. Cars use six lead-acid batteries connected in series to form a 12V battery pack. Regular lead-acid batteries require periodic replenishment of sulfuric acid to maintain the electrolyte at 22–28% dilute sulfuric acid. 2. Classification: Conventional batteries, dry-charged batteries, and maintenance-free batteries.
