Why Can't the Brake Pedal Be Depressed and the Vehicle Fails to Start?

Brake pedal can't be depressed and the vehicle fails to start, the possible reasons may be the disappearance of vacuum in the brake booster pump or air leakage or component failure in the vehicle's brake booster pump. Below are the detailed explanations of the specific causes: Disappearance of vacuum in the brake booster pump: Because the owner stepped on the brake several times after parking, the vacuum in the brake booster pump disappeared, making it difficult to depress the brake pedal without assistance. The booster pump does not work when the engine is off, so the owner can try to start the engine again, press the brake pedal firmly, and it will return to normal after starting. Air leakage in the vehicle's brake booster pump: Due to air leakage or component failure in the vehicle's brake booster pump, the owner will feel very strenuous when stepping on the brake because the booster pump function is lost. If the owner still cannot restore normal operation after stepping on the brake several times, they should go to a nearby repair shop for inspection and continue driving only after the problem is resolved.

Will Insurance Companies Cover Water-Damaged Vehicles?

Insurance companies will assess claims for water-damaged vehicles on a case-by-case basis. If you have purchased auto damage insurance, the insurer will cover water damage to your vehicle. According to auto damage insurance provisions, the insurance company is responsible for compensating total or partial losses of motor vehicles caused by rainstorms, floods, landslides, etc. Moreover, the reformed auto damage insurance includes coverage for vehicle theft, separate glass breakage, spontaneous combustion, engine water damage, no-deductible clauses, and third-party special agreements when the responsible party cannot be found. Estimated impact on the vehicle: In addition to understanding the underwater conditions clearly, you should also make a rough estimate of the difficulty based on the vehicle you are driving. Observe whether the water has reached the floor of the cabin or the exhaust pipe, and check if the water level exceeds the midline of the tires. If either of these two standards is exceeded, it can easily cause severe damage to components such as the vehicle's engine and computer. Conditions for water damage insurance coverage: Simply purchasing comprehensive insurance or water damage insurance does not guarantee coverage for water damage to your vehicle. If the damage is caused by improper operation leading to water ingress, the insurance company will not provide compensation.

Does the car color change registration require the owner to go in person?

For the color change registration, either the car owner or a friend can handle it on behalf of the owner. If a friend is handling it, they need to bring the owner's ID card, along with the "Motor Vehicle Change Registration Application Form", the agent's identity proof, the motor vehicle registration certificate, and the motor vehicle driving license. According to Article 6 of Chapter 2 of the "Road Traffic Safety Law", if the color change area of a motor vehicle does not exceed 30%, there is no need to go through the change registration. On the contrary, if it exceeds 30%, registration is required, and it must be done within 10 days after the vehicle color change. Precautions for vehicle wrap color change: Before preparing to change the color of the vehicle wrap, it is necessary to consult the vehicle management office where the vehicle is registered to see if the region allows the use of wraps to change the vehicle color. If the region does not support this method, the registration procedure cannot be processed after the change, and the wrap must be completely removed to restore the original color of the vehicle. Additionally, according to the "Motor Vehicle Registration Regulations", owners are no longer required to apply to the vehicle management office in advance. They can first change the vehicle color, install body kits, replace the engine, etc., and then apply to the vehicle management office for change registration. According to Article 10, registered motor vehicles must apply for change registration under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Replacement of the entire vehicle due to quality issues. Change of use nature, such as commercial vehicles changed to non-commercial vehicles or vice versa. The owner's residence moves out of or into the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with emblem patterns and equipped with alarms and emblem lights as required. Other motor vehicles are not allowed to paint, install, or use the emblem patterns, alarms, or emblem lights exclusive to the above-mentioned vehicles or similar to them. Article 56 of the "Motor Vehicle Registration Regulations" states that if the body color is changed without going through the change registration as required, the public security traffic management department will issue a warning or impose a fine. The vehicle may also be impounded and required to restore the original body color.

Where to Apply for Vehicle ETC?

ETC can be applied for at bank branches, online service points, or highway service areas. The application requires the original and photocopies of the vehicle owner's valid ID card and vehicle license. If the application is not made by the owner themselves, the agent's valid ID card must also be provided. The photocopy of the vehicle license should include the page stamped with the most recent annual inspection seal. Additionally, a bank debit or credit card application form is required, as this card will be used to bind the ETC card. After obtaining the card, the vehicle owner can go to a designated bank branch to receive and install the ETC onboard device for free, with no additional charges. Applicants must be between 18 and 60 years old and own a vehicle in their personal name. Required documents for official vehicles: An introduction letter from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the agent's original ID card; the original vehicle license; and the vehicle that requires ETC. ETC can also be applied for online. For example, using mobile apps like WeChat or Alipay, search for ETC and follow the prompts to complete the application. Alternatively, directly search for ETC application services and follow the instructions. Since various banks have their own online services and sections, they have launched online ETC application services to facilitate vehicle owners, allowing applications to be made without leaving home. Here are some precautions for ETC installation: Do not obstruct the driver's view; it is best to install it behind the rearview mirror. Many car models have steeply angled windshields, which can reduce the driver's field of vision. Installing the ETC without considering this can increase blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that might block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out, triggering the switch and locking the electronic tag, rendering it unusable. Unlocking will require a visit to an ETC service point. This mechanism is designed to prevent multiple vehicles from sharing one device. ETC usage notes: The ETC transaction sensing range is 8 meters. To avoid issues caused by the preceding vehicle's ETC device malfunction, maintain a distance of more than 10 meters from the vehicle in front to prevent automatic payment for the preceding vehicle. The ETC lane recognition speed is 20 km/h; exceeding this speed may result in failure to read the vehicle's device information and subsequent payment failure. If a debit card is used to bind the ETC, insufficient balance will also cause payment failure.

If you fail the first time, you can retake the test on the same day. If you fail again, you need to pay to reschedule the test. After the test, queue up to receive the score report and sign it. If you do not sign, it will be considered invalid. There is no limit to the number of Subject 1 test appointments. Each subject test can be taken once, and if you fail, you can retake it once.

For Subject 2 and Subject 3, there are only five test opportunities, and the Subject 2 and Subject 3 tests should be scheduled ten days later. If you fail the Subject 3 safe and civilized driving knowledge test, the passed road driving skill test scores are still valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skill test; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in the official terminology (i.e., the Ministry of Public Security Order No. 123), there is no such term as Subject 4.
