Under normal circumstances, a car can drive up to 1,000 kilometers beyond the maintenance mileage without issues. However, frequently exceeding this limit will increase engine wear. Hazards of exceeding maintenance mileage: If engine oil exceeds the maintenance mileage, its fluidity deteriorates, viscosity properties change, and insufficient lubrication increases engine wear and fuel consumption. If coolant exceeds the mileage, the cooling system's heat dissipation performance declines. Deteriorated coolant can form scale in the system, reducing engine cooling efficiency. Excessive temperatures may lead to engine compartment fires. If brake fluid exceeds the maintenance mileage, its quality deteriorates, lowering the boiling point. Prolonged or frequent braking can cause the fluid to overheat and boil, creating air bubbles in the system that directly result in weak or failed braking. Precautions for car maintenance: Follow the recommended time or mileage intervals for maintenance and avoid significant delays. Regularly check tires for cracks, bulges, scratches, or abnormal wear. If any components show abnormalities, promptly send the vehicle for inspection. After each maintenance, reset the maintenance light and related parameters, and clean any spilled fluids to prevent damage to vehicle components.

Can I Take the Subject 2 Test at a Different Test Center?

It is possible to schedule the Subject 2 test at a different test center. Currently, the driver's license test system is interconnected across various districts within the city, allowing students to choose their preferred test venue and register online. Subject 2 Test Scheduling Methods: The driving school can assist students in scheduling the test, or students can independently schedule it online. The scheduling for the Subject 2 test is arranged based on the total number of applicants for that day. Subject 2 Test Notes: Before the test, wear comfortable clothing and prepare mentally. When reversing into the parking space, pay attention to key points—avoid turning left or right. During parallel parking, ensure the rear wheels do not cross the edge line of the parking space, adjust the distance properly, and remember to use the turn signal and honk. For the 90-degree turn, steer sharply once the reference point is aligned. During the curve driving, make wide turns after entering the curve, maintaining a steady speed. Avoid crossing any lines during these maneuvers. After completing the test, drive the car back to the starting position, sign the confirmation, and then turn off the engine. Mock Test: The purpose of the mock test is to familiarize candidates with the test environment and allow the instructor to point out areas where points are easily deducted. When attending the test, be sure to bring your ID card. Without it, you cannot take the test. Ensure your phone is turned off during the test, as any sound from the phone may be considered cheating.

How many points are deducted for rolling back during hill start in Subject 2?

During the hill start in the fixed-point parking on a slope, if the vehicle rolls back less than 30 cm, 10 points are deducted; if it rolls back more than 30 cm, 100 points are deducted. Other point deduction items are as follows: After parking, if the right side of the vehicle body is more than 30 cm away from the roadside line, 10 points are deducted; if it is more than 50 cm away, 100 points are deducted; if the wheel rolls over or touches the line, 100 points are deducted. After parking, if the front bumper is not aligned with the pole line and the deviation is within 50 cm, 10 points are deducted; if the deviation exceeds 50 cm, 100 points are deducted. After parking, if the parking brake is not fully engaged, 10 points are deducted. If the start is not completed within 30 seconds, 100 points are deducted. Stalling once during the start results in a 10-point deduction. If the gear is not in neutral or park when starting the engine, 100 points are deducted. Key points for fixed-point parking on a slope: Upon hearing the instruction for "fixed-point parking on a slope" (approximately 20 meters from the pole), turn on the right turn signal, steer appropriately to the right, and drive slowly along the right side of the road, paying attention to the distance between the vehicle body and the right-side line. When the vehicle is about 10 meters away from the parking pole, approach the target slowly, accurately, and steadily. Accurately estimate the target by aligning a specific point on the windshield (or hood) with the parking pole (this point should be determined during practice due to differences in vehicle models and driver heights). When the windshield point aligns with the parking pole, meaning the vehicle's bumper aligns with the pole line, stop immediately.

What happens if the engine exhaust pipe is not connected?

If the engine exhaust pipe of a car is not connected, it may cause engine noise and abnormal engine operation. The vehicle may fail to meet emission standards, which also has an impact on the environment. Below are the functions of connecting the exhaust pipe in a car: 1. Promotes exhaust combustion: The car exhaust pipe extracts engine exhaust under certain specific conditions and sends part of the exhaust back to the intake manifold, where it mixes with fresh air-fuel mixture and re-enters the cylinder to participate in the combustion process. 2. Improves emissions: Since the exhaust cannot burn, it reduces the combustion speed and temperature inside the cylinder, thereby improving emissions and reducing the content of pollutants.

Can the Subject 4 test be taken every day?

Subject 4 can be taken every day, but it must be scheduled in advance. The relevant introduction to Subject 4 is as follows: Introduction 1: Subject 4, also known as the Subject 4 theory test or driver theory test, 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 test was divided into two parts: the road test and the addition of a safe and civilized driving test, commonly known as "Subject 4," which assesses "driving ethics." Introduction 2: Because this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test. However, there is no official term "Subject 4" in the actual regulations. The test paper consists of 50 questions, mainly in the form of case studies, pictures, animations, etc., with a full score of 100 and a passing score of 90.

Can I take the Subject 2 driving test by myself?

You can take the Subject 2 driving test by yourself, as there is no strict rule requiring you to go with your driving instructor. However, going with your instructor to the test site allows them to inform you about the test procedures or precautions to avoid mistakes during the exam. Before making an appointment, be sure to inform your instructor. According to national regulations, the theoretical study time for Subject 2 must be at least 2 hours, and the practical training must reach 22 hours. This also helps the instructor manage each student's test schedule and test site arrangements. If necessary, the instructor can arrange for a vehicle to pick up and drop off students on the test day. Subject 2 passing criteria: The test is scored out of 100, with deductions of 20 points, 10 points, or 5 points for various errors. A score of 80 or above is required to pass. Subject 2 test content: The test includes reversing into a parking space, parallel parking, straight-line turning, stopping and starting on a slope, and curve driving. Subject 2 is a crucial and the most challenging part of the driving license test. Subject 2 test precautions: Wear comfortable clothing before the test and be mentally prepared. Pay attention to key points when reversing into a parking space—avoid turning left or right. When parallel parking, ensure the rear wheels do not cross the edge line, adjust the distance properly, and remember to use the turn signal and honk. For sharp turns, steer the wheel decisively once you reach the designated spot. During curve driving, make wide turns after entering the curve, maintain a steady speed, and avoid crossing any lines. After the test, drive the car back to the starting position, sign to confirm, and then turn off the engine. Mock tests are designed to familiarize candidates with the test environment and allow instructors to point out areas where points are easily lost. Remember to bring your ID card to the test; without it, you cannot take the exam. Ensure your phone is turned off during the test, as any sound from the phone may be considered cheating.
