Is It Safe to Be in a Car During a Thunderstorm?

It is safe to be in a car during a thunderstorm. The "Faraday Cage" Principle: The car's exterior is primarily made of metal. With the doors and windows closed, the car forms an enclosed space that operates on the same principle as a "Faraday cage." During a thunderstorm, the interior of this space remains unaffected by lightning. Simply put, staying in the car during a thunderstorm is like installing a lightning rod for yourself. During a thunderstorm, a large number of mobile electrons gather on the car's exterior, causing the car's shell to reach a potential similar to that of the lightning. This prevents a potential difference from forming, thereby avoiding any current flow. Precautions During a Thunderstorm: Whether indoors, outdoors, or in a car, it is best to avoid using your phone during a thunderstorm. The instantaneous lightning generates a strong magnetic field, which can interfere with the phone's electromagnetic waves. At best, this may cause signal disruption or damage to the phone; at worst, it could lead to a lightning strike.

Is a car with uneven gaps on both sides of the hood considered a salvage vehicle?

Uneven gaps on both sides of the hood do not indicate a salvage vehicle. The difference in gaps on both sides of the engine hood is an assembly issue. You can have it adjusted at a 4S shop to make the hood gaps even. A car is considered a salvage vehicle if its body frame is damaged in an accident. A car is composed of the body frame and exterior panels. After removing all the exterior panels, what remains is the body frame. The exterior panels include the front fenders, engine hood, front and rear bumpers, doors, and trunk lid. The car's body frame is the foundation for installing all components. In the event of an accident, this frame plays a crucial role in protecting the safety of passengers inside the car. Therefore, cars with damaged body frames must never be purchased. Similarly, if a car's exterior panels are damaged due to an accident, it is not considered a salvage vehicle because exterior panels do not affect safety; they only serve aesthetic and aerodynamic purposes. The identification of a salvage vehicle is based on two assessment criteria. On one hand, it should be determined by the actual loss price assessed by a professional unit with qualified assessment certification. On the other hand, it should be based on the loss price determined by a legally binding judgment from a people's court.

Does the Beidou card need to be registered under my own name?

Beidou card must be registered with your own information. If the Beidou driver card does not belong to the actual driver and is discovered by traffic police, according to relevant regulations, a fine of 2,000-5,000 yuan will be imposed when the actual driver's identity information doesn't match the IC card inserted in the Beidou terminal, along with rectification orders. Below are relevant details: 1. Explanation of Beidou card: Most Beidou recorders will prompt for driver login after inserting the driver information card. To verify whether the driver card is functioning properly, you can print a receipt to check driver information, including driver's license number and name. If discrepancies are found, the driver can prepare ID card, vehicle license, and operating permit to visit the local Beidou service provider for information adjustment. Some regions support electronic and online processing. 2. Mandatory Beidou card: Drivers operating medium or large trucks must obtain a Beidou card. Otherwise, if caught by transportation authorities, penalties will apply. According to the "Road Transport Vehicle Dynamic Supervision Management Regulations," vehicles with malfunctioning Beidou satellite positioning systems cannot engage in transportation. Violators face an 800 yuan fine, but those committing illegal acts like damaging devices, interfering with or blocking signals will be fined 2,000 to 5,000 yuan. Therefore, drivers without Beidou cards are generally considered to be blocking Beidou signals and will face corresponding penalties.

Can motorcycles be equipped with ETC?

Motorcycles cannot be equipped with ETC. How ETC works: Through the on-board electronic tag installed on the vehicle's windshield, dedicated short-range communication is established with the microwave antenna in the ETC lane at the toll station. Computer networking technology is then used for backend settlement processing with the bank, enabling vehicles to pass through highway or bridge toll stations without stopping while still paying the required fees. ETC usage precautions: The ETC transaction sensing range is 8 meters. When the vehicle in front stops, maintain a distance of more than 10 meters to prevent automatic fee deduction for the preceding vehicle in case its ETC device malfunctions or is absent. The recognized speed for ETC lane passage is 20km/h. Driving too fast may prevent reading of vehicle device information, leading to fee deduction failure. Unauthorized removal or movement of the OBU device, or detachment/loosening of the ETC electronic tag will render the tag invalid. It can be taken to the bank where the ETC card was issued or to a highway service office for inspection. Non-deliberate detachment or loosening only requires reactivation. When using a debit card bound to ETC, insufficient balance may cause fee deduction failure. Follow on-site staff guidance to use manual MTC lanes with cash or card payment. Excessively thick windshields may cause poor signal reception. This is particularly important for vehicles that have had windshield replacements after accidents or aftermarket windshield modifications.

What to Do When Your Driver's License Points Are Depleted?

Handling methods when a driver's license accumulates 12 penalty points: 1. For Class A and B licenses: Direct downgrade upon reaching 12 points: For holders of Class A or B licenses, accumulating 12 points within a scoring cycle will result in the vehicle management authority revoking their highest permitted driving category. They must complete downgrade procedures within 30 days. 2. For Class C licenses: Retake the theory test (Subject 1) upon reaching 12 points: If a driver's license is penalized with 12 points (including exactly 12 or more than 12 but less than 24 points), the license will be temporarily suspended. The driver must retake and pass the theory test before being allowed to drive again. Driving during this suspension period is considered unlicensed driving. During the probationary period with 12 points: 1. For Class A and B licenses: Revocation and downgrade: If a driver accumulates 12 points during the probationary period for a Class A or B license, their probationary driving qualification for that category will be revoked. If the revoked qualification is not for the highest permitted category, the highest category will also be revoked. Additionally, for Class A and B license holders, accumulating more than 6 but less than 12 points during the probationary period will extend the probation by one year. 2. For Class C licenses: License revocation: If a Class C license holder accumulates 12 points during the probationary period, their probationary driving qualification will be revoked.

What Causes Severe Car Vibration When Accelerating?

Reasons for car vibration when accelerating: fuel line blockage causing poor fuel supply, air intake system leaks or blockages, damaged ignition coils and spark plugs, excessive carbon buildup in the throttle body, faulty fuel injectors, clogged fuel filter, etc. Below is relevant information: 1. Fuel system issues are generally caused by fuel line blockages leading to poor fuel supply, manifested as engine vibration, unstable idle, or stalling while driving; additionally, fuel pump failure can also cause engine vibration. To diagnose fuel pump issues, disconnect the fuel line and check flow rate and volume. For proper operation, the engine requires sufficient air, adequate fuel, and a well-functioning ignition system. Problems in any of these areas can cause engine vibration. If the intake system has leaks or blockages, acceleration vibration will occur when pressing the accelerator. 2. In the engine ignition system, ignition high-voltage wires rarely fail, so the main issues usually lie with ignition coils and spark plugs, as they are wear-prone components. When spark plugs degrade or inferior-quality spark plugs are used, it can result in weak acceleration or acceleration vibration. 3. The automotive fuel system is extensive with many components, and any abnormal or faulty part can cause engine vibration during acceleration. Examples include excessive carbon buildup in the throttle body, faulty fuel injectors, or a clogged fuel filter. In summary, car body vibration while driving is not a minor issue. Unless it's normal gearshift shock, it should be promptly inspected at a professional repair shop or 4S store.
