What are the inconveniences of having an out-of-town license plate?

Will the insurance company fully compensate for a water-damaged car?

If a car is submerged in water, the auto damage insurance may not necessarily provide full compensation, as it depends on the actual circumstances. For insurance purchased before September 19, 2020, both auto damage insurance and waterlogging insurance must be purchased. Additionally, if the car stalls due to the owner not restarting the engine or not moving the vehicle, the insurance company will provide full compensation. However, if the auto damage insurance was purchased after the 2020 auto insurance reform, it already includes waterlogging insurance. Therefore, for losses caused by engine waterlogging, owners who have purchased auto damage insurance will receive full compensation. Losses caused by restarting the engine are not covered by waterlogging insurance. Moreover, after a car is submerged in water, insurance companies usually compensate based on the actual loss. If the loss exceeds the coverage limit, no compensation will be provided. For example, if the auto damage insurance coverage is 200,000, the insurance company will pay a maximum of 200,000.

Does crossing the stop line refer to the front or rear wheels touching the line?

Crossing the stop line refers to the rear wheels of a motor vehicle touching the line. Only when the entire vehicle crosses the stop line is it considered to have fully passed it. When driving, if the front wheels accidentally cross the line, stopping in time will not be considered running a red light but rather stopping beyond the line. However, if there is clear intent to continue moving, it will be judged as running a red light. Do not attempt to reverse after crossing the line. Traffic regulations prohibit reversing at intersections, as it can easily lead to collisions with vehicles behind. Generally, running a red light is determined by three photos showing the vehicle's position: the first photo shows the vehicle crossing the stop line, the second shows the vehicle in the intersection, and the third shows the vehicle passing through the intersection. Only if all three positions correspond to a red light can it be confirmed as running a red light. Violating traffic rules by improperly driving or stopping at an intersection will result in a 2-point penalty and a fine.

Should a Flooded Car Be Scrapped or Repaired?

Make the choice based on the extent of water damage. If the car is damaged by more than 70%, it should be scrapped; if the flooding is relatively minor with minimal damage, opt for repairs. Generally, flooded cars are categorized into three levels: a waterlogged car refers to water levels exceeding the chassis; if water surpasses the oil dipstick, it's called a semi-submerged car; and if water rises above the engine cover or dashboard, it's termed a fully submerged car. All three scenarios can be repaired, but they carry certain risks—the longer the soaking time, the higher the likelihood of malfunctions. Whether a damaged vehicle should be scrapped is determined by professional insurance assessors. If the vehicle's loss exceeds 70% of its actual value, it is generally considered a total loss, and you can file a claim with the insurance company. However, note that full compensation does not equate to the price of a new car; it only covers the car's actual value, not its new-car value.

What is Refrigerant Oil?

Air conditioning compressor lubricant is commonly referred to as refrigerant oil, which can circulate within the air conditioning system along with the refrigerant. Refrigerant oil is a highly refined, foam-free, wax-free, and moisture-free lubricant. In addition to providing lubrication, sealing, and cleaning functions like conventional lubricants, the moisture-absorbing properties of air conditioning lubricant differ from other lubricants. If moisture is mixed with the refrigerant, it can produce hydrochloric acid, which corrodes components and causes the expansion valve to freeze and clog. A small amount of refrigerant oil circulating with the refrigerant in the cooling system can serve a moisture-absorbing function. Therefore, refrigerant oil is dehydrated during production and should be sealed during use to prevent absorption of moisture from the air. Introduction to Automotive Air Conditioning Refrigerant Oil: R22, chemically known as chlorodifluoromethane, is a type of Freon and belongs to the hydrochlorofluorocarbon (HCFC) class. Currently, R22 refrigerant still holds the largest share in air conditioning applications, primarily used in older air conditioning systems. However, R22 refrigerant poses significant harm to the ozone layer and is being phased out gradually. R410A refrigerant is currently positioned as an environmentally friendly refrigerant, composed of a quasi-azeotropic mixture of two components, mainly consisting of hydrogen, fluorine, and carbon elements. It is characterized by stability, non-toxicity, and superior performance. While it does not deplete the ozone layer, it does contribute to greenhouse gas emissions. R32, short for difluoromethane, is a cooling agent with zero ozone depletion potential. At room temperature, it exists as a gas and appears as a colorless, transparent liquid under its own pressure. It is easily soluble in oil but difficult to dissolve in water. Additionally, R32 has a low viscosity coefficient and a high thermal conductivity. However, R32 is a flammable and explosive refrigerant.

What Causes the Black Screen on the Buick LaCrosse Center Console Display?

Buick LaCrosse center console display black screen is caused by poor contact between the host and the display connection. You can try re-plugging the data cable or replacing the data cable. For the vehicle's center console display, it operates after the car is started, with the brightness set to default and generally does not require adjustment. In the car's lighting control area, there is a switch to adjust the brightness of the center console display. Moving the scroll wheel up and down can adjust the brightness. The interior lighting of the center console automatically turns on when the headlights are activated, and its brightness can also be adjusted. However, if the center console display remains completely black and cannot be adjusted or restored, first turn off the car's engine, then disconnect the car's battery terminals to discharge and reset the car's control computer, and finally reconnect the power to try again. If the issue persists, timely repair is necessary.

What is the function of the three-way catalytic converter in a car?

The three-way catalytic converter is the most important external purification device installed in the automotive exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The substrate of the three-way catalytic converter is a porous ceramic material installed in a specially designed exhaust pipe. It does not participate in the catalytic reaction itself but is coated with precious metals such as platinum, rhodium, and palladium that facilitate the reaction. The three-way catalyst begins to react at a minimum temperature of 350°C. When the temperature is too low, the conversion efficiency drops sharply; excessively high temperatures can also accelerate catalyst aging. To check whether the catalytic converter is damaged or overheated during operation, observe its surface for dents, severe discoloration spots, or slight bluish and purple traces on the shell. Additionally, due to catalyst substrate breakage, peeling, or oil accumulation, the channels in the substrate can become blocked, increasing flow resistance. This can be checked by measuring the pressure loss.
