How Many Times Can You Take the Subject 1 Driving Test?

In principle, as long as the driving test registration is valid (3 years), there is no limit to the number of retakes. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the Subject 1 test can be taken twice. If the first attempt is unsuccessful, the second retake is free. If the second attempt is still unsuccessful, the Subject 1 test is terminated, and you can only reschedule the test after ten days. Subject 1, also known as the Subject 1 theory 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 is computer-based and has a time limit of 45 minutes. To pass the Subject 1 driving test, a score of 90 is required. The test consists of 100 questions, divided into 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 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 test, students should pay attention to their attire—no sandals are allowed. Electronic devices and bags are not permitted 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 a locker before entering the examination room. Inside, verify your identity at the designated area to be assigned a seat. Once seated, begin the test. Ensure the camera is aimed at you and follow test discipline. If you fail the first attempt, a same-day retake is allowed. 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 reschedule the Subject 1 test. Each subject test allows one retake if the first attempt is unsuccessful. If you do not attend the retake or fail it, the test is terminated, and the applicant must reschedule. For Subject 2 and Subject 3, only five test attempts are allowed, and rescheduling must be done ten days later. If the Subject 3 safe and civilized driving knowledge test is failed, the passed road driving skills test scores remain 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; and 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, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject 4."

What is the mileage for the first car maintenance?

The first car maintenance is usually required between 3 to 5 months, with a mileage ranging from 3,000 to 5,000 kilometers, and for some cars, it can be as long as 8,000 kilometers. The exact timing and mileage may vary depending on the car brand. Before the first maintenance, which is also the running-in period of the vehicle, there are several things to pay attention to: 1. There is no requirement for constant speed driving, but do not exceed two-thirds of the maximum speed. The engine RPM should not exceed 3,000-3,500 (different car manufacturers may have different requirements for engine RPM). Avoid sudden acceleration and sudden braking. 2. Do not overload the vehicle, and regularly check tire pressure, coolant, and brake fluid. 3. When driving downhill for a long distance, control the speed properly. Do not use engine resistance to slow down the car. For manual transmission models, anticipate gear shifts in advance and avoid shifting gears at inappropriate speeds.

How Long Can Fully Synthetic Engine Oil Be Used?

Fully synthetic engine oil has a maintenance cycle of 12 months or 12,000 kilometers. If the overall road conditions are good, with minimal congestion and highway mileage accounting for more than 75% of the total, it can be replaced at 15,000 kilometers. Below is an introduction to the functions of engine oil: 1. Lubrication: Engine oil forms a lubricating film between the piston and cylinder, reducing friction. 2. Sealing: The oil film formed by engine oil helps prevent gas and oil leaks. 3. Cleaning: Engine oil circulates to carry away carbon deposits, sludge, and wear particles from engine components back to the oil pan. 4. Cooling: The circulation of engine oil helps dissipate some of the heat generated by the engine.

What Are the Reasons for the Constant Illumination of the Car Engine Warning Light?

There are mainly 7 reasons for the engine warning light to illuminate: Sensor malfunction: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to illuminate. Fuel quality issues: If fuel and engine oil are not added as required by the manufacturer, it may cause engine wear and trigger the warning light. Poor combustion of the air-fuel mixture: Poor combustion of the air-fuel mixture can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockage can all cause poor combustion of the engine's air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, high oil consumption, reduced power, metallic noises, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the car's intake, it may cause engine pipeline blockage, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can lead to intake problems. Exhaust issues: Exhaust faults can also cause the engine warning light to illuminate. The rear oxygen sensor, catalytic converter, exhaust camshaft, and bearing failures are all causes of exhaust problems, with the catalytic converter being the most common. Using leaded gasoline, lead or silicon-containing lubricant additives, physical damage to the catalytic converter, or fuel system faults can easily lead to catalytic converter failure. Anti-theft system malfunction: If the car's electronic anti-theft system malfunctions, or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can also prevent the engine from operating normally and cause the engine warning light to illuminate. If the engine warning light is on, you can follow these steps: First, check if the engine is running normally and whether there are issues such as shaking or smoke. If so, avoid restarting the engine. Especially note that you must not restart the engine if the red light is on. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the 'on' position without pressing the clutch. The car will perform a self-check after powering on. Wait for 5-10 seconds and observe whether the warning light on the dashboard turns off. If the warning light does not turn off, visit a service station as soon as possible to identify the cause. The service station can use a portable diagnostic tool to read the fault code, obtain fault information, and perform targeted repairs.
