In summer, turning on the AC switch is necessary to cool the car; otherwise, the air conditioning system only operates the blower, delivering air at normal temperature. Function of the AC button: The AC button in a car's air conditioning system is responsible for delivering cool air. The car's air conditioning system includes not only the compressor but also components like the condenser, evaporator, and expansion valve. However, the compressor is one of the most crucial parts of the refrigeration system, as it compresses and transports refrigerant vapor. Meaning of the AC button: The AC button on the car's dashboard controls the air conditioning function, allowing users to turn the interior air conditioning on or off and adjust the temperature inside the car. It is a highly convenient and practical button. Generally, in semi-automatic air conditioning systems, the AC switch automatically turns on when the blower is activated. If AC is not needed, it must be manually turned off.

It is indeed necessary to turn on the air conditioning when driving in summer. The high temperatures can cause the interior of the car to rise above 40°C, and without air conditioning, it can lead to excessive sweating, dehydration, or fatigue during prolonged driving. This is especially risky for individuals with health concerns, such as the elderly or children, as such heat can trigger heatstroke. I always start the air conditioning in advance to cool down the car, setting the temperature to a comfortable range of 24-26°C—too low can cause shivering and discomfort. Additionally, a well-maintained car air conditioning system not only cools efficiently but also saves fuel. It's advisable to check the refrigerant and filters quarterly to prevent bacterial growth that could affect respiratory health. Using air conditioning isn’t about luxury; it’s about driving safety and mental relaxation. After all, without proper cooling during highway driving or traffic jams, it’s hard to stay focused, increasing the risk of accidents.

Does Compulsory Insurance Cover Water Damage to Vehicles?

Compulsory insurance does not cover water damage to vehicles. To claim for water damage, the vehicle owner needs to purchase waterlogging insurance. Waterlogging insurance primarily covers engine damage caused by driving through waterlogged roads or being submerged in water. It includes situations such as vehicle collisions, falling objects, collapses, storms, heavy rain, floods, earthquakes, mudslides, landslides, and other incidents that result in vehicle damage. Therefore, whether the vehicle is parked in an underground garage, unable to be moved due to heavy rain on the road, or submerged due to natural disasters like floods or typhoons, except for engine damage caused by restarting the engine, the compensation is covered by vehicle damage insurance. Cases where waterlogging insurance does not provide coverage: Engine damage caused by restarting the engine; damage or repairs to the insured vehicle due to incidents outside the scope of motor vehicle damage insurance; repairs at non-insurer-approved repair shops resulting in substandard repair quality and the need for rework; delays in vehicle repairs by the insured or the driver.

Does the vehicle have to be under my name to apply for an ETC?

It is possible to apply for an ETC even if you are not the vehicle owner. According to the "Implementation Plan for Accelerating the Application of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the following documents are required: the original valid ID card of the vehicle owner, the original and a copy of the vehicle registration certificate (showing the most recent annual inspection stamp). If applying on behalf of someone else, the original valid ID card of the agent is also required. If applying through bank branches, a debit or credit card from the respective bank is needed. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding with a debit card. ETC Charging Principle: Highways have one or more ETC lanes. Communication between the vehicle's on-board electronic tag (installed on the windshield) and the microwave antenna in the ETC lane enables automatic toll deduction via backend banking systems, eliminating the need to stop at toll booths. This operates on a "pass first, charge later" principle. Benefits of Installing ETC: Time-saving: Eliminates waiting in queues. Eco-friendly: Reduces noise and emissions by avoiding idling at toll booths. Cost-saving: Minimizes wear and fuel consumption by reducing frequent stops and starts. Efficiency: ETC lanes can process vehicles 2-3 times faster than traditional methods, making them more advanced and efficient. Compared to license plate payment, ETC technology is more mature and advantageous. Policy Support: The State Council's "13th Five-Year Plan for Modern Integrated Transportation System Development" aims for widespread ETC adoption by 2020, targeting a 50% usage rate for passenger vehicles. Future Possibilities: Beyond improving ETC convenience and adoption rates, future plans include expanding ETC use for trucks and integrating it with vehicle-to-vehicle and vehicle-to-infrastructure communication for smarter transportation solutions. ETC Usage Notes: Maintain a 10-meter distance from the vehicle ahead in ETC lanes to avoid unintended toll charges due to faulty or absent ETC devices. Keep speed below 20km/h in ETC lanes; excessive speed may cause reading failures. Tampering with or dislodging the OBU device may deactivate it. Non-deliberate issues can be resolved by reactivation at the issuing bank or highway service center. Insufficient funds in a linked debit card may cause charging failures. Follow staff guidance to use cash or cards in manual lanes. Thick or modified windshields may interfere with ETC signal reception, especially after repairs or replacements.

What does violation code 1039B mean?

Violation code 1039B means: Driving a non-motorized vehicle in violation of traffic diversion, restricted passage, or prohibited passage regulations. Article 56 of the Road Traffic Safety Law of the People's Republic of China: Motor vehicles shall be parked in designated areas. Parking motor vehicles on sidewalks is prohibited. Article 93: For violations of laws and regulations regarding motor vehicle parking or temporary stopping, the illegal act may be pointed out, and an oral warning may be issued, ordering immediate departure. If the motor vehicle driver is not present or refuses to leave immediately, obstructing the passage of other vehicles or pedestrians, a fine of 20 to 200 yuan shall be imposed, and the motor vehicle may be towed to a location that does not obstruct traffic or to a place designated by the traffic management department of the public security organ. The traffic management department of the public security organ shall not charge the party for towing and shall promptly inform the party of the parking location. Traffic violation codes consist of four to five digits, classified according to the principles of the traffic law. The order from left to right is: the first digit represents the behavior classification code, the second digit represents the penalty point classification code, the third and fourth digits represent the sequential code, and the fifth digit represents the item number of the clause. First digit: Behavior classification code, indicating the category in the Road Traffic Law. Second digit: Penalty point classification code, indicating the penalty points for the traffic violation. Third and fourth digits: Sequential code, indicating the order of the behavior within the same classification. For example: 13035—"1" indicates motor vehicle behavior, the second digit "3" indicates 3 penalty points, and "035" indicates the fifth item of the third clause in the 3-point penalty category. Behavior classification code violation descriptions: Codes starting with 1 indicate motor vehicle passage, e.g., 1003. Codes starting with 2 indicate non-motor vehicle passage, e.g., 2002. Codes starting with 3 indicate pedestrian or passenger passage, e.g., 3030. Codes starting with 4 indicate highway passage, e.g., 4002. Codes starting with 5 indicate other regulations, e.g., 5005. Codes starting with 7 indicate implementation rules of provinces, autonomous regions, or municipalities, e.g., 7008. Codes starting with 8 indicate local regulations of cities (prefectures, autonomous prefectures, or leagues), e.g., 8606. There are four common methods for motor vehicle violation inquiries: Visit the office halls of traffic branches in various districts and counties to inquire through touch query terminals. Log in to the external service websites of the public security traffic management bureaus of various cities, find the vehicle violation inquiry section, enter the license plate number and engine number, and click to inquire. Call the inquiry hotline (area code + 114). Use the Traffic Management 12123 app (V2.8.1B437 for iOS 15+ or V2.8.1B274 for Android 12+) to inquire. Violations involving driving non-motor vehicles in violation of diversion, restricted passage, or prohibited passage regulations can be processed through the Traffic Management 12123 app. After logging in, enter the violation processing business process, complete the processing, and make the payment.
