Using toothpaste to clean car windows is harmful to the car. Toothpaste is typically composed of many substances with abrasive properties, such as calcium hydrogen phosphate, calcium carbonate, silicon dioxide, calcium pyrophosphate, aluminum hydroxide, etc. The characteristics of these substances determine that toothpaste has a friction function. If toothpaste is used to clean glass, under light, you can see numerous fine scratches. Toothpaste can be used to treat some minor scratches on the car body. The principle is that the particles in the toothpaste fill in the scratches. The specific method is as follows: first, clean the scratch with water, then take a clean cloth, apply a small amount of toothpaste to the scratch and gently rub it. Once the scratch disappears or weakens, wipe it dry with a wet cloth.

Why is the Practice for Subject 3 Limited to Only 3 Days?

There is no regulation that restricts the practice for Subject 3 to only 3 days; it should be based on your actual situation. The amount of time spent practicing for Subject 3 does not directly correlate with the test results, meaning more practice does not guarantee a pass. Content of Subject 3: The road driving skills test for Subject 3 generally includes: vehicle preparation, simulated lighting test, starting, driving straight, gear shifting operations, lane changing, pulling over, going straight through intersections, left turns at intersections, right turns at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting other vehicles, overtaking, making U-turns, and night driving. Important Notes for Subject 3: In the 100-meter gear shifting test of Subject 3, the requirements for speed and gear selection are very strict. Generally, first gear is used for speeds between 10--20 km/h, second gear for 20--30 km/h, third gear for 30--40 km/h, fourth gear for 40--50 km/h, and fifth gear for speeds above 50 km/h. Using a low gear at high speeds or a high gear at low speeds can cause severe shaking of the vehicle, and the computer system will automatically deem the test as failed.

Can I Bring My Own Photo for the License After Passing Subject Four?

Generally, you cannot bring your own photo for the license after passing Subject Four, but the specific process may vary depending on the local driving test procedures. After passing Subject Four, some vehicle management offices will use the portrait information collected during registration to produce the license, while others will collect portrait information on-site after passing Subject Four or allow you to bring your own photo for the license. Nowadays, most vehicle management offices adopt the first method. After the Subject Four results are uploaded, the system will directly use the photo taken during driving school registration to produce the license, so you cannot bring your own photo. However, if you want to change the photo, you need to communicate with the driving school in advance and have them collect your portrait information again. Once the new photo is uploaded to the system, the updated photo will be used for the license. Otherwise, you will have to communicate with the staff at the test center to see if they can use the photo you brought for the license. Requirements for driver's license photos: The background color should be white, and you should not wear uniforms. The portrait should be clear, with rich layers, natural expression, and no obvious distortion. The photo size should be 32mm x 22mm, with a head width of 14mm to 16mm and a head length of 19mm to 22mm. The photo can be pasted or digitally printed. The photo should be taken at the vehicle management office or a licensed photo studio. Both men and women should not wear earrings, and those who need vision correction should wear glasses. Women should not have their hair loose, and men should not have excessively long hair. The head should occupy about two-thirds of the photo. Applicants applying for a motor vehicle driver's license or temporary motor vehicle driving permit must provide a front-facing, bareheaded, color half-body ID photo taken within the last six months.

Is ID Card Required for Subject 1 Exam?

An ID card is required for the exam, while the admission ticket and other documents are handled by the driving school, which will distribute them during the exam. Electronic ID cards cannot be used for the exam. If you don't have an ID card, you can apply for a temporary ID card, which holds the same validity as a formal ID card. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the Subject 1 exam can be taken twice on the same day. If you fail the first attempt, you can take a free second attempt. If you fail the second attempt, the Subject 1 exam will be terminated, and you can only reschedule the exam after ten days. The Subject 1 exam consists of 100 questions, including single-choice and true/false questions, with each question worth 1 point and a total score of 100. If you answer 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. The Subject 1 exam is computer-based and lasts for 45 minutes. The content of the Subject 1 exam includes: regulations on driving licenses and motor vehicle management; road traffic conditions and regulations; traffic safety violations and penalties; regulations on road traffic accident handling; 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. Notes for the Subject 1 exam: Candidates should pay attention to their attire and are not allowed to wear slippers. Electronic devices and bags are not permitted in the exam 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 exam room. At the identity verification area, you will be assigned a seat. Once seated, begin the exam, ensuring the camera is aligned with you and adhering to exam discipline. If you fail the first attempt, you can retake the exam on the same day. If you fail again, you will need to pay to reschedule. After the exam, queue to collect your score report and sign it. Failure to sign will render the result invalid. There is no limit to the number of times you can reschedule the Subject 1 exam. Each subject can be taken once, and if you fail, you can retake it once. If you do not take the retest or fail the retest, the exam will be terminated, and you must reschedule. For Subject 2 and Subject 3, there are only five exam attempts. Subject 2 and Subject 3 exams can be rescheduled after ten days. If you fail the Subject 3 safe driving knowledge test, the previously passed road driving skills test results remain valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the exam on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skills test. Subject 3 is divided into two parts: road driving skills and safe driving knowledge. 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."

What Causes Car Battery Leakage?

Here are the specific reasons for car battery leakage: 1. Cracks on the exterior: Battery leakage may occur due to aging or even cracking of the seal between the upper cover and the base. In this case, it is necessary to inspect the battery's exterior for any cracks. If found, plastic welding should be used to repair them. After repair, the electrolyte concentration should be checked to ensure the battery functions properly. 2. Leakage from components: This could be due to leakage from the safety valve or wiring connections. Remove the battery panel and check for any leakage marks on the safety valve.
