Can C1 directly apply for A2?

Driver's license C1 cannot directly apply for A1 or A2 models, but can directly apply for upgrading to A3, B1 or B2. To upgrade to A2, the applicant must have held a B1 or B2 license for more than three years with no full-point records in the previous two cycles, or have held an A1 license for more than one year with no full-point records in the previous cycle. According to the new regulations, the A2 (tractor) driver's license cannot be obtained directly, but only through upgrading. C1 driver's license: The C1 driver's license allows driving small and micro passenger cars, light and micro trucks; light, small and micro special operation vehicles. C1 driver's license cannot drive: Large buses, tractors, city buses, medium buses, large trucks, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, trams, etc.

What is the role of OBD in a vehicle?

OBD in diesel vehicles stands for "On-Board Diagnostics." Below are the functions of OBD: 1. OBD determines specific faults based on specific algorithms. The main purpose of this system is to monitor the engine while driving. Once the exhaust emissions exceed the standard, the malfunction indicator light will illuminate, and fault codes will be stored. 2. If the exhaust emissions exceed the standard, the malfunction indicator light will turn on to alert the owner to perform repairs. Trucks are required to undergo an annual OBD emissions test, and failure to pass will result in not receiving the compliance certification. 3. The useful information obtained from the system's self-diagnosis can assist in vehicle maintenance and repairs. Technicians can use the manufacturer's specialized equipment to read fault codes, enabling quick fault localization for efficient vehicle repairs and reducing the time required for manual diagnostics.

What are the Three Filters in Car Maintenance?

Car three filters refer to the air filter, fuel filter, and oil filter. The "three filters" play a filtering role for air, oil, and gasoline in the car engine, thereby protecting the engine. 1. Air filter: Ensures the air entering the engine is clean. There is a lot of dust suspended in the air, mainly composed of silicon dioxide, which is a substance harder than metal. Installing an air filter can reduce the wear of parts such as cylinders, pistons, and piston rings. If a car does not install it, cylinder wear will increase by 7 times, piston wear by 3 times, and piston ring wear by 8 times. Therefore, modern car engines are equipped with air filters at the carburetor (or the intake control device of fuel injection engines). 2. Fuel filter: Ensures the fuel is clean and prevents vapor lock. During the storage, transportation, and refueling process of gasoline, it is inevitable to mix in some impurities and water. These impurities are brought into the fuel supply system and engine cylinders with the fuel, accelerating cylinder wear. Before gasoline enters the fuel pump, it must be filtered to ensure the normal operation of the fuel supply system. 3. Oil filter: Filters the oil to ensure the normal operation of the engine, and is the most important among the three filters. During the use of internal combustion engines, mechanical impurities such as dust, metal shavings, and carbon deposits will continuously mix into the oil. At the same time, the oxidation of oil by air and combustion exhaust gases will gradually produce gum. The mixture of mechanical impurities and gum will also form sludge, which not only accelerates the wear of moving parts but also easily causes oil circuit blockage. To ensure the cleanliness of the oil, the engine is equipped with an oil filter in the lubrication system.

Is the car's braking system front or rear wheel?

Automobiles utilize braking on both front and rear wheels, with the driving wheels typically applying greater braking force than the non-driving wheels. Here's additional information: 1. For front-wheel-drive vehicles like sedans, the front wheels provide primary braking while the rear wheels assist. The parking brake acts on the rear wheels. 2. The automotive braking system, also called the automotive stopping system, serves to: forcibly decelerate or stop moving vehicles as required by drivers; maintain stationary vehicles on various road conditions (including slopes); and stabilize speed during downhill driving. 3. Currently, most domestic automakers employ front-disc-rear-drum braking systems for medium and small production vehicles, though some models feature four-wheel disc brakes. Compared to drum brakes, disc brakes offer more advanced technology, lighter weight, superior heat dissipation, better braking performance, and enhanced adaptability to complex weather and road conditions.

What to Do When the Car Still Rolls Despite the Handbrake Being Engaged?

Here are the reasons why a car might still roll despite the handbrake being engaged: 1. The brake clearance is too large, reducing the pressure of the friction pads against the drum or disc when the handbrake is applied. 2. The handbrake is not fully engaged. 3. If the car rolls only a short distance, it may indicate an issue with the engagement point between the handbrake and foot brake. 4. The slope is too steep, or the road surface is too smooth. Here are the solutions to prevent rolling: 1. If the car is stuck on a slope and starts to roll backward, the first thing the driver should do is stay calm and not panic. Quickly press the foot brake to stop the car, then gently pull the handbrake and slowly release the foot brake. It is best to keep the foot on the foot brake until the handbrake is confirmed to be securely engaged before releasing the foot brake.

Is the original license plate automatically canceled after vehicle transfer?

After the vehicle is transferred, the original license plate will be automatically canceled. After the vehicle is transferred, the original license plate can be applied for retention within two years. The right to use the license plate will be retained after two years of transfer. This means that if the original license plate is not used within two years, the license plate number will be automatically canceled. After the vehicle is transferred, if you still want to keep the original license plate, you should go to the relevant department as soon as possible to apply the license plate number to your newly purchased vehicle. Only in this way can you continue to use the original license plate; otherwise, it will be automatically invalidated. To retain the original license plate, you also need to understand the conditions that must be met. For example, all traffic violation records of the original vehicle must be cleared, and the original license plate must have been used for more than one year. The original owner of a second-hand vehicle transfer needs to provide documents including the registration certificate, vehicle license, and ID card. The buyer needs to provide an ID card, and if they are from another city, a residence permit or temporary residence certificate is required. Vehicle transfer first requires a vehicle evaluation. The evaluation fee is generally 1%-2% of the evaluated vehicle price, and other fees include those for the license plate and vehicle license. The original vehicle's commercial insurance can be canceled (compulsory insurance cannot be canceled), or the insurance can be transferred to the buyer at the insurance company. Precautions for purchasing second-hand vehicles: Incomplete procedures. Complete procedures for second-hand vehicles include: vehicle registration certificate (or original purchase invoice), vehicle license, vehicle purchase tax payment certificate, road maintenance fee procedures, and compulsory insurance. If the vehicle registration certificate or vehicle license is missing, or if there are arrears in compulsory insurance or road maintenance fees, it will cause endless trouble for the buyer. Therefore, when purchasing a vehicle, if the seller cannot provide complete procedures, consumers should be particularly vigilant. Tampering with the odometer. Most consumers like to judge the condition of a vehicle based on the odometer, and sellers often take advantage of this psychology to tamper with the odometer. In fact, the odometer is not only an indicator of usage intensity but also a recorder for the maintenance and replacement of other vehicle parts. If the buyer performs maintenance based on the tampered odometer reading, it will bring a series of potential safety hazards. New paint covering 'external injuries'. When consumers choose second-hand vehicles, if the old vehicle has been repainted and there are signs of repair around the front face, rear, and A, B, and C pillars, the vehicle is very likely to have been involved in a major traffic accident. 'Tuning the heart' to raise the price. Many consumers often pay too much attention to the 'heart' of the car when buying a vehicle and neglect the health of the car body. Second-hand vehicle sellers take advantage of this psychology by replacing engine parts to make the vehicle's 'heart' appear younger, thereby raising the price.
