Can a Temporary ID be Used for the Written Driving Test?

A temporary ID can be used for the written driving test (Subject 1). A temporary ID is a citizen identity document used during the period of applying for, renewing, or replacing a resident ID card. It holds the same legal validity as a formal ID, but its validity period is only three months. Therefore, a temporary ID meets the identity verification requirements for the initial application of a driver's license. Materials required for applying for a temporary ID: Household registration booklet; Resident ID collection receipt; Bring the required materials to the household registration office of the local police station, fill out the application form, and submit it. However, note that electronic IDs cannot be used for the test. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the Subject 1 test can be taken twice. If the first attempt is unsuccessful, a second free retest is allowed. If the second attempt also fails, the Subject 1 test is terminated, and the applicant must wait ten days before reapplying. The test is computer-based and lasts 45 minutes. Subject 1 test content: Regulations on driver's licenses and motor vehicle management; road traffic conditions and rules; traffic safety violations and penalties; regulations on traffic accident handling; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and cargo vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: Candidates should dress appropriately—no slippers allowed. Electronic devices and bags are prohibited in the test room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen. Store personal belongings in lockers before entering the test room. At the identity verification station, a seat will be assigned. Once seated, begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, a same-day retest is available. If you fail again, you must pay to reschedule. After the test, queue to collect your score report and sign it. Failure to sign renders the result invalid. There is no limit to the number of times you can schedule the Subject 1 test. Each subject can be taken once, with one retest allowed if unsuccessful. If you skip the retest or fail it, the test is terminated, and you must reschedule. Subjects 2 and 3, however, allow only five attempts each. Scheduling for Subjects 2 and 3 must be done ten days later. If you fail the Subject 3 safety and civilized driving knowledge test, your passing score for the road driving skills test remains valid. Steps to schedule the Subject 1 test online: Open the Traffic Safety Comprehensive Service Management Platform and select your province/city. Choose "Test Scheduling." Click "Register Now." Fill in user information: Enter your ID number and the phone number used during registration. Select user type: Choose "First-time applicant for a motor vehicle driver's license." Enter the SMS verification code. Read and agree to the terms, then click "Next." Confirm the information is correct and click "Next." Test scheduling: Select the test subject, test venue, and scheduling period. Enter the image verification code and click "Next." Choose the date and session: The system offers two scheduling modes—self-selecting test sessions or letting the system arrange them. If you choose the self-selection mode, you can pick one or multiple sessions. If you opt for system arrangement, the system will automatically match available sessions within your selected period. After selecting, click "Next" to confirm. Review and confirm the information, then click "Complete." Upon successful submission, the system generates a transaction number. The test schedule will be arranged and announced on the result announcement day. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 covers traffic safety laws, regulations, and related knowledge. Subject 2 is the field driving skills test. Subject 3 includes two parts: road driving skills and safety and civilized driving knowledge. The safety and civilized driving knowledge test is taken after Subject 3, often referred to as "Subject 4," though this term is unofficial (per the Ministry of Public Security's Order No. 123). The test duration is 45 minutes.

What is the safe tire pressure range for sedans?

The standard normal tire pressure for sedans is 2.3-2.5 bar. Below is relevant information about car tire pressure: Introduction to car tire pressure: Tire pressure refers to the air pressure inside the tire. Methods for detecting tire pressure: Direct tire pressure monitoring: Connected tire pressure monitoring devices use pressure sensors installed on each tire to directly measure tire pressure. Wireless transmitters then send the pressure information from inside the tire to a central receiving module, which displays the tire pressure data. When the tire pressure is too low or there's a leak, the system automatically alerts. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is that when the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than other wheels. The purpose of monitoring tire pressure is to compare speed differences between tires. In practice, indirect tire alarm systems monitor tire pressure by calculating the rolling radius of the tires.

How to Deal with Car Rust?

Car rust needs to be addressed based on its location. The methods for handling rust in different parts of the car are as follows: Car Paint Rust: Use very fine sandpaper dipped in water to gently sand away the rust. Avoid random sanding; instead, sand in straight lines in the same direction. Once completely cleaned, apply a layer of primer. For new scratches, a touch-up pen can be used directly. Car Chassis Rust: The underside of the vehicle can be treated with chassis armor or sealing to protect it from acid rain and corrosion, preventing the original protective layer from cracking or peeling. Car Brake Disc Rust: Rust can be removed by continuous braking while driving. If the rust is severe and causes noticeable vibrations in the brake pedal or steering wheel, it is necessary to have a repair shop remove the brake disc for sanding to eliminate the rust. Trunk Rust: Regularly inspect the trunk and air out the carpet frequently, or place some desiccants inside the trunk. Electrical System Rust: Regularly check the electrical system. If any wires show signs of aging, replace them promptly.

Does a small gear driving a large gear accelerate or decelerate?

A small gear driving a large gear results in deceleration. When a small gear drives a large gear, the rotational speed decreases, which is based on the principle of gear ratio. When two gears of different diameters mesh and rotate together, the larger diameter gear naturally rotates slower than the smaller one. The speed ratio is inversely proportional to the gear diameters. Relevant information about gears is as follows: 1. Introduction: A gear is a mechanical component with teeth on its rim that continuously mesh to transmit motion and power. The use of gears in transmission has a long history. With the development of production, the smooth operation of gears has gained importance. 2. Teeth: Each protruding part on a gear used for meshing. Generally, these protrusions are arranged radially. The teeth of paired gears come into contact with each other, enabling continuous meshing and operation.

What to Do When the Car Won't Start After Refueling?

The car may fail to start after refueling due to issues with the spark plugs, a weak battery, or blocked fuel flow. Here are some possible causes and solutions: 1. Check the spark plugs: Spark plugs are crucial to the car's ignition system, which is essential for the engine to work. The performance of the spark plugs affects the overall operation and efficiency of the vehicle. 2. Weak battery: The starter may begin to turn but lacks sufficient power, eventually making only a clicking sound. In winter, low temperatures can prevent the car from starting as the battery voltage drops below the rated value, causing the starter to malfunction. 3. Blocked fuel flow: There may be no oil pressure in the engine's fuel supply line. This is often caused by long-term dirt accumulation in the fuel lines. At extremely low temperatures, water mixed with debris can block the fuel lines, resulting in the inability to start.
