Do vans need a freight transport qualification certificate for cargo transportation?

If the van is used for freight transportation, it does not require an operating permit. However, if it is a passenger-type van, it cannot be used for freight operations. Since January 1, 2019, the management of vocational qualification certificates and vehicle operating permits for ordinary freight transport vehicles with a total mass of 4.5 tons or less has been adjusted. Below are the relevant details: Regulations: Starting from January 1, 2019, transportation management departments in various regions will no longer issue road transport permits for ordinary freight vehicles with a total mass of 4.5 tons or less. From January 1, 2019, for ordinary freight transport activities conducted by vehicles with a total mass of 4.5 tons or less, transportation management departments must not impose administrative penalties on such vehicles or drivers for reasons such as 'operating without a license' or 'driving road passenger or freight transport vehicles without the corresponding vocational qualification certificate.' Commercial road freight transport drivers must meet the following conditions: possess the corresponding motor vehicle driving license; be no older than 60 years of age; and have a basic understanding of relevant road freight transport regulations, motor vehicle maintenance, and cargo loading and storage.

What are the symptoms of air in the radiator?

The most obvious symptom is that the warm air inside the car is not hot. When there is air resistance in the radiator's coolant, it causes poor circulation of the coolant, which is a sign of air in the radiator. Even after filling the radiator with coolant, if it does not circulate at the normal rate within the engine, a high-temperature warning may still appear. This is likely caused by excessive air in the radiator. Below is additional information: 1. Car Radiator: Also known as a heat exchanger, it is a key component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket in a continuous cycle, thereby achieving temperature regulation. It is also an essential part of the car's engine. 2. Radiator Principle: The radiator is a crucial component of a water-cooled engine. As an important part of the engine's cooling circuit, it absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, its temperature does not rise significantly after absorbing heat from the engine block. Thus, the engine's heat is transferred through the liquid coolant circuit, using water as the heat carrier. The heat is then dissipated through large-area cooling fins via convection, maintaining the engine's optimal operating temperature.

How many days can a car key be used after getting wet?

It is uncertain how long it takes for a car key to dry naturally after getting wet, as it depends on factors such as air temperature and humidity. Based on their working methods, car keys can be divided into three categories: active working mode, passive working mode, and coil induction mode. The specific working methods of car keys are introduced as follows: 1. Active working mode: The principle is to control the car door through the vehicle's electronic module and body control module. Simply press the key button to send an unlock/lock command, and after verification by the vehicle's electronic module, the door can be opened/closed. 2. Coil induction working mode: Mainly involves placing an encrypted chip inside the key. During the unlocking process, the vehicle's RF transceiver verifies whether the key matches to determine if the engine can be started. This is mainly used in special cases where the key has no power, allowing the car to still start normally. 3. Passive working mode: When the owner enters the sensing area of the key system, as long as they touch the door handle, the identity-recognition "key" they carry will receive a low-frequency signal sent by the car. If this signal matches the identity-recognition information stored in the "key," the "key" will be awakened.

Should the clutch be released quickly after shifting in a manual transmission?

Release the clutch slowly. Slowly releasing the clutch allows for a full engagement between the engine and the transmission. If the clutch is released too quickly, the engine will encounter significant resistance. If the throttle is not applied sufficiently at this moment, noticeable power loss will occur, potentially causing the engine to stall during startup or creating jerky movements during normal driving. Here are some precautions: 1. Avoid looking down at the gear lever when shifting: Whether you're driving swiftly in the city or cruising on the highway, never look down at the gear lever when shifting. The moment you look down, you might miss an unexpected obstacle ahead—time is of the essence when driving. 2. On synchronized gears: It's possible to downshift without rev-matching (adding empty throttle) by using a single clutch press, but this can lead to increased wear and premature damage to components. 3. Avoid veering off course when shifting: Steady driving requires coordination between the left hand on the steering wheel and the right hand on the gear lever. Some drivers shift smoothly, while others are more hasty, failing to position the gear lever correctly, which can cause the vehicle to veer off course with serious consequences.

What are the requirements for taking a driver's license test across provinces?

First, you need to prepare your ID card and a one-inch white-background color photo, then go to the local vehicle management office where you want to transfer to complete the transfer procedures. The driver's license test is an examination to obtain a motor vehicle driver's license, and the content and subjects of the test are unified nationwide. The following is a relevant introduction to the driver's license test: 1. Test content: The test is divided into four parts: theoretical knowledge, field driving skills, road driving skills, and civilized driving-related knowledge. Chinese citizens aged 18 and above can take the test. 2. Passing standards: Subjects 1 and 4 are conducted in a written test format, with a full score of 100, and a score of 90 or above is considered passing. The field driving test is Subject 2, with a full score of 100, and a score of 80 or above is considered passing. Subject 3 is the road driving test with a full score of 100. Depending on the type of vehicle being tested, there are two passing standards: 90 or above and 80 or above. Passing all four subjects will qualify you to obtain a driver's license.

How to Turn On the High Beam and Low Beam of a Car?

In most car models, the light control mechanism is located on the left side of the steering wheel, and the operation of the high beam and low beam is completed on the left side of the steering wheel. The difference is that the low beam switch may be on the left lever or on an independent light knob on the left side, while the high beam switch is always on the left lever. The usage instructions for high and low beams are as follows: 1. When meeting another vehicle at night, switch to low beam when the oncoming vehicle is more than 150 meters away. 2. Use low beam when meeting non-motorized vehicles on narrow roads or bridges at night. 3. When a motor vehicle passes through an intersection controlled by traffic lights at night, use low beam when turning. 4. When a motor vehicle passes through sharp curves, slopes, arch bridges, crosswalks, or intersections without traffic light control at night, alternately use high and low beams to signal. 5. Do not turn on the high beam in foggy weather, as the high beam's light axis is tilted upward, and the emitted light is diffusely reflected by the fog, creating a white haze in front of the car, which makes it harder for the driver to see clearly.
