What Type of License is Required for Towing a Trailer?

Trailer towing requires an A2 driver's license. The A2 license permits the operation of tractor vehicles capable of towing heavy and medium-duty full trailers and semi-trailers. Additionally, vehicles that can be driven with an A2 license include: B1 (medium-sized buses), B2 (large trucks), C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled vehicles), and M (wheeled self-propelled machinery). According to the regulations on the application and use of motor vehicle driving licenses, in China, a legally valid A2 license allows the driver to operate full trailers and semi-trailers. A full trailer is defined as one where the total weight of the trailer is borne by itself, while a semi-trailer is one where part of the total weight is borne by the tractor vehicle.

What Causes the Humming Noise When the Transmission Bearing is Broken?

The humming noise when the transmission bearing is broken is caused by the increased gap before it fails, leading to a decrease in fitting accuracy and resulting in abnormal sounds. The transmission, also known as the gearbox, is an automotive component used to alter the speed and torque from the engine, and can fix or change the gear ratio between the output and input shafts. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also including a power take-off mechanism. It can be categorized into stepped, continuously variable, and integrated transmissions, featuring functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios. The transmission is a crucial component in a vehicle, as it can alter the gear ratio and expand the torque and speed of the driving wheels.

How Much Coolant Should Be Added at One Time?

Coolant should be added 5 to 6 liters at a time. Coolant, whose full name is antifreeze coolant, is often thought to be used only in winter, but in fact, it is used all year round. Antifreeze is a type of coolant with special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as antifreeze in winter, anti-boil in summer, and anti-scale and anti-corrosion throughout the year. Below are the functions of coolant: 1. Prevent corrosion of metal parts and aging of rubber components; 2. Prevent the coolant from freezing and expanding in cold seasons when the vehicle is parked, which could crack the radiator and damage the engine cylinder block; 3. Prevent the engine water temperature from becoming too high, ensuring the engine operates at the proper working temperature; 4. Reduce scale formation to avoid clogging the circulation pipes and affecting the cooling system's heat dissipation function; 5. Provide lubrication for the water pump, thermostat, and other components.

Can You Drive with Low Engine Coolant?

Whether you can drive with low engine coolant depends on the fluid level in the expansion tank. Details are as follows: 1. Short distance: If there is still fluid, you can drive a short distance, but you need to add coolant as soon as possible. 2. Hazards: If there is no fluid, you cannot drive, as it may easily cause engine piston scuffing or cylinder seizure. Engine coolant, also known as antifreeze or radiator fluid, serves the following purposes: 1. Cooling: Cools engine components. 2. Freezing prevention: Prevents the coolant from freezing. 3. Rust prevention: Protects cooling system components from rust. 4. Overheating prevention: Prevents parts from overheating.

How to Handle Traffic Violations on the 12123 App?

Methods for handling violations on the 12123 app: 1. Scan the relevant QR code: Scan the QR code of the registered vehicle, follow the prompts to take the required photos, fill in the detailed information, and enter the SMS verification code of the vehicle owner. 2. Fill in the relevant information: After entering the details and the SMS verification code of the registered vehicle owner, the system will automatically review and approve the information, allowing you to proceed with the violation handling. The following are the impacts of unhandled traffic violations: 1. Late fees: If an on-site ticket is not paid within 15 days, late fees will be incurred. 2. License and vehicle seizure: If more than 3 violations remain unhandled, the traffic police may seize the driver's license upon inspection, and in severe cases, the vehicle may also be seized. 3. Impact on license renewal, replacement, or transfer: Unhandled on-site tickets will prevent the driver from renewing, replacing, or transferring their driver's license. 4. No insurance compensation: In case of accidents or vehicle damage, the vehicle insurance company will not provide compensation. 5. Impact on vehicle annual inspection: The vehicle will not pass the annual inspection.

Where to Add Water to the Car Radiator?

The water filler port of the car radiator is generally located on the right side of the engine compartment, usually next to the windshield washer fluid filler port. Relevant information about the radiator is as follows: 1. The radiator is usually located behind the air conditioning condenser: Opening the engine compartment only reveals the upper cover of the radiator; the exact position of the radiator can only be clearly seen after removing the front bumper cover. 2. Coolant is suitable for all seasons: Although water is also a type of coolant and can cool the engine, the coolant filled in the engine is a mixture of coolant concentrate and water in a specific standard ratio. However, water alone is considered a low-grade coolant, which is not only affected by seasonal changes but also prone to scale and rust. In contrast, coolant is suitable for all seasons, of high quality, and ensures reliable performance. 3. Adding water to the radiator is not permitted by manufacturers: If damage to the radiator or engine occurs due to adding water, it will not be covered under warranty, leaving the owner to bear the consequences. The most troublesome issue for drivers using water as a coolant is the problem of scale. Scale adheres to the metal surfaces of the radiator and water jacket, increasingly reducing the cooling efficiency and making it difficult to remove.
