How many days does it take to receive a notification for traffic violation photos?

Generally, SMS notifications for traffic violation photos are received within 3 to 7 days, with a maximum of around 13 days. However, some cities now offer "instant electronic police capture alerts," where you can receive an SMS notification within 5-10 minutes of being captured. But this notification does not equate to a violation; it merely serves as a capture alert. The final determination of whether it constitutes a violation takes 3-7 days. If it is confirmed as a violation, you will receive another SMS notification. For traffic violations captured by surveillance cameras, vehicle owners typically do not receive an immediate violation notification via SMS. There is usually a delay, and the duration can vary. After an electronic camera captures a violation, the relevant violation information needs to be transmitted through a dedicated channel to the traffic police management center. It is then compiled and forwarded to the relevant traffic police personnel for verification. Once confirmed as a violation, the system automatically retrieves the vehicle owner's phone number based on the license plate information and sends the violation details via SMS. After receiving the violation SMS, vehicle owners must visit the traffic police department at the location of the violation within one month before the vehicle's annual inspection. If a vehicle owner suspects a violation, they can use 15 days as a benchmark. If no violation SMS is received within 15 days, it is likely that no violation was recorded. Methods for querying traffic violations: Traffic violation queries refer to checking motor vehicle violations of traffic management rules through online platforms or query terminals. Methods include terminal queries at traffic police branches, traffic violation websites, phone queries, and mobile app queries. Website query: You can search for "vehicle violation query" and enter your vehicle information to check. Phone query: Dial local 114 (area code + 114) or 12580 to confirm traffic violations. Violations can only be processed at the location of the violation or the vehicle's license plate issuance location. For on-the-spot violations, such as those directly caught by a traffic officer, they must be processed at the violation location. Mobile app query: Open the "Traffic Management 12123" app, select "violation query," and clear any unresolved violations.

Reasons for Friction Noise When Braking?

Friction noise when braking is commonly caused by issues such as noise in new cars, brake disc and pad noise, or sudden braking noise. Noise when braking in new cars: The brake pads and discs of new cars have not yet fully worn in, so they may sometimes produce a "squeaking" friction sound, which is normal. After some use, the noise will naturally disappear. Noise after replacing brake pads: After installing new brake pads, incorrect installation can cause noise. Common installation errors include installing the brake pads upside down, with the metal side touching the brake disc, resulting in braking noise. Noise due to brake disc issues: Prolonged use can cause deep grooves on the brake disc surface or deep steps at the edges. Uneven contact between the brake pads and the disc can produce noise. In such cases, the brake disc needs to be replaced or polished using a brake disc resurfacing machine. Noise from sand in the brake disc: If foreign objects like sand or small stones get between the brake pads and disc while driving, the brakes may produce a sharp hissing sound. Continuing to drive normally will usually dislodge the sand or stones, eliminating the noise. If the noise persists, the wheel may need to be removed to extract the debris. Noise during sudden braking: When braking suddenly, if you hear a noise and feel vibrations in the brake pedal, this is a normal phenomenon caused by the activation of the ABS system.

Can the in-car dash cam pick up sounds inside the vehicle?

Can the in-car dash cam pick up sounds inside the vehicle? The answer is yes, because dash cams are capable of recording audio. A dash cam is an instrument that records images, sounds, and other relevant information during vehicle operation. The recording function can be enabled in the settings of the dash cam. Below are the functions of a dash cam: 1. Protecting the legal rights of drivers: In cases involving pedestrians, bicycles, or motorcycles crossing the road, it can help drivers avoid extortion by providing solid evidence. 2. Facilitating the determination of accident liability: In the event of an accident, replaying the recorded footage makes it clear who is at fault, allowing traffic police to handle the situation quickly and accurately. It also enables vehicles to be removed from the scene promptly, helping to restore traffic flow while preserving crucial evidence. This contributes to a safe and smooth traffic environment and ensures fairness. 3. Serving as a deterrent to reduce accident rates: With a dash cam installed, drivers are less likely to engage in reckless driving, significantly lowering the incidence of accidents. Even if an accident occurs, the dash cam can capture relevant information about the involved vehicles, greatly reducing hit-and-run cases. 4. Providing evidence for insurance claims: In cases where compensation for traffic accident damages needs to be determined by court rulings, the dash cam can offer evidence, leading to more accurate sentencing and compensation. 5. Effectively preventing fraud: When encountering professional fraudsters or road robbers, the dash cam can record the scene of the incident and the appearance of the perpetrators, providing key evidence for solving the case. 6. Documenting life experiences: Many car owners enjoy road trips and use dash cams to record their journeys—whether smooth and scenic or rough and muddy—all of which make for memorable experiences.

Why is my application for the Subject 1 exam still under review?

When applying for the Subject 1 exam online, the reservation status typically shows whether it was successful or not within 24 hours. If the reservation page continues to display "under review," it indicates that the reservation was unsuccessful, and you need to cancel and reapply. Below is an introduction to the driving test subjects: 1. Subject 1: The exam on road traffic safety laws, regulations, and related knowledge. The structure of the exam question bank and the basic question types are determined by the Ministry of Public Security, while provincial traffic management departments under the public security authorities establish the exam question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. 2. Subject 2: The field driving skills test, which includes: reversing into a parking space, stopping and starting on a slope, turning at a right angle, driving along a curve, and parallel parking. In cities like Shanghai, Subject 2 consists of nine mandatory items: reversing into a parking space, turning at a right angle, parallel parking, driving through a tunnel, stopping to take a card, driving along a curve, making a U-turn on a narrow road, emergency stopping, and stopping and starting on a slope. 3. Subject 3: The road driving skills test, which includes basic items such as: preparing to drive (walking around the vehicle counterclockwise, fastening the seat belt, turning on the left turn signal, shifting gears, releasing the handbrake, and honking the horn), starting, driving straight, changing lanes, passing through intersections, pulling over, passing through pedestrian crosswalks, passing through school zones, passing through bus stops, meeting oncoming vehicles, overtaking, making U-turns, and driving at night. 4. Subject 4: Safe and civilized driving knowledge, which tests related knowledge on safe and civilized driving.

How long after passing Subject 1 will Subject 2 become invalid?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the validity period of the study driving certificate is three years, but the expiration date must not exceed the upper age limit for application. Applicants must complete the Subject 2 and Subject 3 tests within the validity period. If the tests are not completed within the validity period, the passing scores of already completed subjects will become invalid. Subject 1, also known as the theoretical driving test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test format is computer-based, with a time limit of 45 minutes. Subject 1 consists of 100 single-choice and true/false questions, each worth 1 point. If 11 questions are answered incorrectly during the test, the system will automatically submit the test and end the session. Subject 1 test content: Driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: During the Subject 1 test, students should pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in lockers before entering the examination room. Upon entering, verify your identity at the assigned seat and begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After completion, queue to collect your score sheet and sign it—failure to sign will render the result invalid. There is no limit to the number of times Subject 1 can be scheduled. Each subject can be taken once, with one retake allowed if failed. If the retake is not attended or is failed, the test session ends, and the applicant must reschedule. For Subject 2 and Subject 3, there are only five test attempts, and rescheduling must be done at least ten days later. If the Subject 3 safe driving knowledge test is failed, the passing score for the road driving skills test remains valid. The driving test consists of three subjects: 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 skills test; Subject 3 is divided into two parts: road driving skills and safe driving knowledge test. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject 4."

Why is there a hump in the middle of the rear seats of a car?

The reason for the hump in the middle of the rear seats is to reserve space for four-wheel drive and to increase strength. Reserving space for four-wheel drive: Many SUV models and rear-wheel-drive vehicles have to make a hump in the rear seats to reserve space for the drive shaft. In comparison, front-wheel-drive vehicles have a lower hump because they do not need to accommodate a large component like the drive shaft, only needing to reserve space for components such as the exhaust pipe and muffler. Increasing strength: Vehicles with a rear seat hump do not necessarily have higher body strength, but some models increase the hump to enhance body strength. These two aspects are not contradictory, as many models add a steel beam in the middle of the rear seats to increase strength. Increasing the height between the car chassis and the ground: Because the chassis of a family car cannot be too close to the ground, as it would threaten driving safety. Early German car manufacturing used a frame structure, the most important feature of which was to ensure the integrity of the car body during collisions, thereby protecting passengers inside. Due to the structural nature of the frame, the middle of the rear seats was raised. Therefore, German and American cars often have a more noticeable hump in the middle of the rear seats, while Japanese and Korean cars have less of one. Arranging the exhaust pipe and drive shaft requires a certain hump in the rear seats of a car. Family cars are generally front-wheel-drive vehicles, lacking a drive shaft, so some cars may not have a hump in the middle of the rear seats. However, rear-wheel-drive and four-wheel-drive vehicles must use a drive shaft to power the rear axle. This raises an issue: the exhaust pipe also needs to pass through the middle of the chassis. Arranging both together is not feasible, so a groove is designed to accommodate the drive shaft and exhaust pipe. The groove design enhances the hardness of the chassis, improving the overall safety of the vehicle. As a result, there is a hump in the middle of the rear seats, making the car's layout more reasonable and the chassis safer. For safety reasons, car manufacturers may have the capability and technology to change the layout of the rear seat hump. However, they do not do so because the groove design of the chassis and the frame design of the entire vehicle are intended to ensure the quality and safety of the car. Even though this design increases manufacturing and design costs, for a car, the most important thing is to withstand collisions without deformation while on the road and to protect the lives of passengers.
