M-class license is a driver's license for wheeled self-propelled machinery. Additional information: 1. Classification of wheeled self-propelled machinery: Wheeled self-propelled machinery is divided into rail wheeled self-propelled machinery and ordinary wheeled self-propelled machinery (including tire-type and hub-type). The former includes train locomotives, bullet trains, rail cars, rail motorcycles, rail cranes, and railway-specific construction machinery (excluding ordinary freight carriages). The latter includes automobiles, tire cranes, road rollers, tractors, harvesters, and specialized construction machinery (excluding automobile trailers). 2. Permitted vehicle types: (1) A1: Large passenger vehicles (other permitted vehicle codes: A3, B1, B2, C1, C2, C3, C4, M); (2) A2: Heavy and medium-sized full trailers and semi-trailers (other permitted vehicle codes: B1, B2, C1, C2, C3, C4, M); (3) A3: City buses with a capacity of 10 or more people (other permitted vehicle codes: C1, C2, C3, C4); (4) B1: Medium-sized passenger vehicles (including city buses with a capacity of 10 to 19 people, other permitted vehicle codes: C1, C2, C3, C4, M); (5) B2: Heavy and medium-sized trucks; heavy and medium-sized specialized operation vehicles.

Is It Okay to Run the Air Conditioning While the Car Is Idling?

Effects of running the air conditioning while the car is idling: If the car is left idling with the air conditioning on for an extended period, it can lead to increased carbon buildup in the engine. The cooling principle of a car's air conditioning system is relatively simple. When cooling, the compressor clutch engages, and the engine drives the compressor to operate. Below are some precautions for using a car's air conditioning system: 1. Refrigerant continuously expands and absorbs heat: The refrigerant inside the evaporator can continuously expand and absorb heat, thereby cooling the evaporator. The cooled evaporator then cools the air blown by the blower, allowing the car's air conditioning vents to blow cold air. 2. Regularly add refrigerant: The refrigerant used in car air conditioning is R134a, and it needs to be replenished periodically. If refrigerant is not added for a long time, the cooling efficiency of the air conditioning system may decline, and the cooling speed may slow down. It is recommended to regularly replenish the refrigerant in the car's air conditioning system. 3. Regularly clean the car's air conditioning system: The interior of the air conditioning system can harbor many bacteria. When cleaning the air conditioning system or adding refrigerant, it is essential to visit a professional service center where trained personnel can perform the task using professional equipment.

Does Vehicle Damage Insurance Include Water Damage Coverage?

Water damage coverage has been integrated into vehicle damage insurance, so vehicle damage insurance now includes water damage coverage. Water damage coverage is also known as automobile loss insurance and special engine loss insurance. Before the auto insurance reform, water damage coverage was an additional insurance that vehicle owners had to purchase specifically for the engine, and it had to be attached to the main insurance policy. Below is additional information: Important Notes: The subject of water damage coverage is the engine of the insured vehicle. This means that only engine damage caused by situations like flooding can be claimed. If flooding causes damage to other parts such as the interior or circuit boards, these are not covered under water damage coverage. However, damage to the interior or circuits falls under the scope of vehicle damage insurance, so vehicle owners can still file claims with the insurance company for these damages.

Is there any damage if driving a distance with a flat tire?

No, driving with a flat tire will damage both the tire and the wheel rim. Whether it can still be used depends on the actual situation. Generally, if a leak is detected, you should stop immediately, replace it with the spare tire, and then go to a repair shop to fix the tire. Below is additional information about flat tires: Near-zero tire pressure: If the tire pressure is close to zero, driving a distance will usually render it unusable. If there is still some pressure left, it depends on how far you have driven. The tire needs to be removed and inspected to determine if it can still be used. How to check for a flat tire: If signs of driving with a flat tire are visible on the tire, such as sidewall abrasion marks or bubbles in the inner liner, the tire is not worth repairing because its structure may have been compromised and it can no longer be used.

Does leaving the car idling with the air conditioning on consume fuel?

It does consume fuel. Fuel consumption increases when idling, so keeping the air conditioning on for extended periods while parked will burn a significant amount of fuel. Here is additional information about idling with the air conditioning on: Causes engine carbon buildup: Incomplete fuel combustion during idling can lead to carbon deposits in the engine. Severe engine carbon buildup can affect normal vehicle startup, reduce engine power, increase fuel consumption, and exceed exhaust emission standards. Health hazards: Incomplete fuel combustion produces high levels of carbon monoxide, which may accumulate around the vehicle and enter the cabin through the air conditioning system, potentially posing health risks.

Will the engine be affected after driving through water?

If the vehicle is not restarted after driving through water, the engine will not be affected. Below is extended information on parts that need to be inspected or cleaned after wading through water: Chassis: Rainwater on the road is usually muddy, and dirt in the water can easily adhere to the chassis. If not cleaned promptly, these contaminants can cause rust on the chassis. Therefore, after wading through water, the chassis should be thoroughly cleaned at a repair shop, with special attention paid to areas such as the axle shafts, tie rods, suspension, and brakes. Headlights: If the headlight covers are not well-sealed, water can easily enter the headlights, forming condensation and affecting the lighting performance. If water enters the headlights, immediate remedial action should be taken; if not addressed in time, replacement may be necessary.
