Can a temporary ID card be used to take the Subject 4 exam?

A temporary ID card can be used to take the Subject 4 exam, as it holds the same validity as a regular ID card. Simply visit any public security bureau, submit your household registration booklet, a recent one-inch black-and-white photo without a hat, and pay a fee of 10 RMB for the document. You can obtain the temporary ID card on the same day. The Subject 4 exam consists of 50 questions, primarily in the form of case studies, images, and animations. The total score is 100, with a passing score of 90. Subject 4, also known as the theoretical exam for drivers, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and an additional safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is colloquially called the Subject 4 exam. Officially, there is no such term as Subject 4. If you fail the Subject 4 exam, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own without any additional fees. There are no restrictions on the number of retakes, but the driving skill test permit is valid for three years. If the applicant does not complete the exam within this period, the results of any passed subjects will become invalid.

What to Do If ETC Card Is Lost?

ETC card replacement method: The vehicle owner should bring their ID card, the original and a copy of the vehicle registration certificate to the bank counter to apply for card change, replacement, or reissuance. The installation process of the ETC device is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. The red light will briefly turn on, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield. The chip should be inserted into the OBU device. ETC device activation method: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth On." If "Tag Invalid" appears when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on the top of the electronic tag to enable Bluetooth directly. Turn on the mobile phone's Bluetooth and open the corresponding mobile app (usually a download QR code is provided on the electronic tag), then enter the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete the activation.

Coolant Refill Location?

The coolant refill location is situated at the vehicle's radiator. Drain the coolant, then add new coolant, and tighten the drain valve once fresh coolant begins to flow out. Coolant Replacement Method: Before performing a complete coolant replacement, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. The five-way hose is named for its five connection points that link various components; coolant flows through it before being distributed to different parts of the vehicle to function. If there are signs of coolant leakage in this area, replace the hose or resecure the connections as needed. Drain the old coolant, then flush the fluid channels with clean water. Add water to the coolant reservoir, then continue filling until water flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may appear slightly pinkish; keep adding clean water until the outflow is clear. Note: Remember to disconnect the heater hose to drain any remaining water from the heater core. Coolant Replacement Interval: For vehicles that operate extensively, such as taxis, high-quality coolant should generally be replaced annually. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolant can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, replace it promptly and clean the system.

What is the Vehicle Certificate Number?

The certificate number is the number on the vehicle's documentation. When a vehicle is approved, the certificate of approval is a necessary document. Only vehicles with this certificate can meet the national standards for motor vehicles and be sold on the market. A vehicle also has a Vehicle Identification Number (VIN), which is essentially the car's "ID number." It is a unique 17-digit code used to identify the manufacturer, engine, chassis number, and other specifications of the vehicle. The vehicle certificate is issued with the vehicle upon production. When registering the vehicle for a license plate, the certificate must be submitted to the vehicle management office for archiving and replaced with the motor vehicle registration certificate. Therefore, the certificate for unregistered vehicles should be held by the dealer, while the certificate for registered vehicles is stored in the vehicle management office's archives. Both the VIN and the certificate number are essential documents required for motor vehicle registration. The VIN, engine number, and chassis number must match the information on the vehicle's factory certificate to facilitate registration, annual inspections, and transfer of ownership. Missing any of these can cause significant issues. The vehicle certificate is an accompanying document issued with the vehicle and must be submitted to the vehicle management office when applying for a license plate, after which it is replaced with the motor vehicle registration certificate. The motor vehicle certificate number can be found in the first column at the top left corner of the vehicle certificate. When purchasing a vehicle, the certificate must be provided to the buyer along with the vehicle; otherwise, the normal registration and licensing procedures cannot be completed.

Do vehicles with ETC enjoy highway toll discounts?

Vehicles with ETC do enjoy highway toll discounts, and banks offering ETC services often provide additional incentives to encourage more applications. Since 2020, vehicles without ETC or not using ETC are no longer eligible for toll discounts. In the future, highway toll stations will retain only one manual lane, requiring non-ETC vehicles to pay tolls manually, which is less efficient compared to ETC lanes. ETC Deduction Principles: Highways feature one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's onboard electronic tag (installed on the windshield) and the microwave antenna in the ETC lane, coupled with computer network technology for backend bank settlements, vehicles can pass through toll stations without stopping. This system operates on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by eliminating stops at toll stations; Cost-saving: Minimizes vehicle wear and fuel consumption by reducing frequent starts and brakes; Improved efficiency: ETC lanes can theoretically process vehicles 2-3 times faster, making them more advanced and efficient. Compared to license plate payment systems, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Integrated Transportation System" explicitly states the goal of "achieving interoperability of transit cards in major city clusters and significantly increasing the proportion of vehicles equipped with ETC by 2020." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020." Future possibilities: Beyond improving ETC installation convenience and passenger vehicle usage rates, future efforts will promote ETC adoption for trucks and explore deeper integration with smart transportation initiatives like vehicle-to-vehicle communication and vehicle-road coordination, offering comprehensive travel services to drivers. This means more application scenarios will support ETC. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the preceding vehicle stops, maintain a distance of over 10 meters to avoid accidental toll payments for the other vehicle due to ETC device malfunctions or absence. The recognized speed for ETC lane passage is 20 km/h. Excessive speed may prevent reading vehicle device information, leading to failed deductions. Unauthorized removal or displacement of the OBU device, or a loose/detached ETC electronic tag, will render the tag ineffective. These issues can be resolved by visiting the bank where the ETC card was issued or a highway service center for reactivation if the detachment was unintentional. Insufficient balance in a debit card linked to ETC may cause deduction failures. Follow on-site staff guidance to use manual MTC lanes with cash or card payments. Overly thick windshields may impair ETC signal reception. This is particularly relevant for vehicles with replaced or modified windshields after accidents.
