According to the regulations, for passenger vehicles, the height of cargo loaded on the roof rack must not exceed 0.5 meters from the top of the vehicle and must not exceed 4 meters from the ground. Below is relevant information about car roof racks: 1. Definition: According to the authoritative definition by car2100, a car roof rack refers to a bracket installed on the roof of a vehicle for securing large items, serving as the foundation for all roof-mounted solutions. 2. Purpose and Brands: Roof racks are most commonly used for self-driving travel, paired with roof boxes or roof baskets to carry travel luggage, thereby increasing interior space. They can also be used to transport other sports equipment such as skis, bicycles, sailboats, etc. There are no fewer than 50 roof rack brands available in the market.

As a veteran driver with twenty years of experience, I'd like to share some advice: installing a roof rack must strictly comply with the 2021 traffic regulations. The new rules state that the height of the rack cannot exceed 50 centimeters above the car roof, and the total vehicle height must not exceed 4 meters, otherwise fines and penalty points are unavoidable. During installation, first check the mounting points, buy a sturdy rack, and secure it tightly with bolts; never skimp on quality with inferior products—I've seen the disastrous consequences of racks coming loose on the highway. Do not exceed the vehicle's weight limit, distribute the load evenly, as overloading can damage the roof and affect braking. After installation, perform a shake test to check for looseness; safety is no small matter. While roof racks can save interior space for luggage during trips, don’t overlook the risks just for convenience.

What to Do If Driving Someone Else's Car Without a License and the Car Gets Impounded?

Driving a motor vehicle without a license will result in a fine and may also lead to detention for up to 15 days, as well as temporary impoundment of the vehicle. If the motor vehicle is unlicensed or has incomplete documentation, the necessary procedures must be completed or a fine paid before the vehicle can be retrieved.

What to Do If Water Gets into the Engine Oil?

If water gets into the engine oil, it is necessary to drain all the oil and replace it with new oil. The main causes of water entering the engine oil are as follows: 1. Damage to the oil cooler causing water to enter the oil: If the pipes of the oil cooler break, external water can seep into the oil cooler, leading to water contamination in the oil. 2. Leakage from the engine water plug causing water to enter the oil: After several years of engine use, corrosion from scale can cause some water plugs to rust through, allowing coolant to enter the oil passages and drain into the oil pan. 3. Damage to the cylinder liner seal causing water to enter the oil: A damaged cylinder liner seal is a major cause of water entering the oil. Therefore, when diagnosing the cause of water in the oil, always check the condition of the cylinder liner seal. 4. Cracks in the cylinder liner leading to water entering the oil: When a heated cylinder liner comes into direct contact with coolant, cracks can form. Once cracks appear, coolant can enter the cylinder directly and seep into the oil pan through the cylinder walls, causing the oil to turn milky. This can result in poor engine combustion, white smoke, and other issues. 5. Damage to the cylinder head gasket causing water to enter the oil: If the cylinder head gasket is damaged and the coolant circulation is fast, water from the coolant passages can flow into the oil passages, contaminating the oil.

Check if the free travel of the clutch lever is too large, and adjust it if necessary. Inspect the wear condition of the clutch friction plates and whether the adjustment bolts are loose, and replace the friction plates in time. Check the length and elasticity of the clutch springs, and replace them if they do not meet the requirements. For oil-type clutches, check the viscosity of the engine oil inside, and replace it with new oil if the viscosity is too high.

What is the process for transferring ownership of a private motorcycle?

Pay the used vehicle transaction tax. The vehicle undergoes external inspection, number tracing, license plate removal, and photography. Collect the vehicle photos and attach them to the inspection record form, then proceed to the transfer hall to complete the filing procedures. After obtaining a number from the ticket machine, queue up with the relevant materials to pay the transfer fees. Required materials include the Motor Vehicle Registration, Transfer, and Cancellation Form/Transfer Application Form, Inspection Record Form, original motor vehicle property registration certificate, etc.

Why does the 12V auxiliary battery of an electric vehicle frequently run out of power?

The following are the main reasons why the 12V auxiliary battery of an electric vehicle frequently runs out of power: 1. Some system settings only supply power to the auxiliary battery when the vehicle is started: Certain electric vehicle system configurations are designed such that the high-voltage battery only charges the auxiliary battery when the car is running, and stops supplying power once the vehicle is turned off. Therefore, sometimes the auxiliary battery is already severely depleted, but the owner turns off and locks the car to charge the electric vehicle. At this point, the charging process cannot replenish the auxiliary battery, resulting in the auxiliary battery being completely drained after sitting overnight. 2. Excessive charging duration: Some electric vehicles can recharge the auxiliary battery even when turned off during charging. However, once charging is complete, even if the charging cable remains connected, the auxiliary battery will not receive additional charges—meaning each charging session only replenishes the auxiliary battery to full capacity once. Meanwhile, the auxiliary battery continues to power various electronic control modules and electrical components in the vehicle, slowly discharging until it is completely depleted. 3. Electric vehicle in an extremely low-power state: Sometimes, when an electric vehicle is in an extremely low-power condition, recharging may no longer be able to replenish the auxiliary battery. This is because the pathway for the converter to charge the auxiliary battery itself requires power from the auxiliary battery to maintain contact closure. Once the auxiliary battery lacks sufficient power to keep the contacts closed, the high-voltage battery cannot recharge the auxiliary battery.

How to Handle Traffic Violations When Driving Someone Else's Car?

If the violation was captured by an electronic eye, you need to prepare the vehicle license. If it was a speeding violation, you need to prepare the vehicle license, driver's license, and a copy of each. After preparing the required materials, go to the vehicle management office to check the violation record and fill out an acknowledgment form. Take the acknowledgment form to the bank designated by the vehicle management office to pay the fine. If the violation occurred in another location, you generally need to handle it at the local traffic police station or vehicle management office where the violation took place.
