How Many Multiple-Choice Questions Are There in Subject 4?

Subject 4 consists of 30 multiple-choice questions, including 20 single-choice questions and 10 multiple-choice questions, with the remaining 10 being true/false questions. The total is 50 questions, primarily presented in the form of case studies, images, and animations. The full score is 100, and a passing score is 90. 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: in addition to the road test, a safety and civilization knowledge test was added, commonly referred to as "Subject 4," which assesses "driving ethics." Because this test is conducted after Subject 3, it is commonly called the Subject 4 test. Officially, however, there is no Subject 4. If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own, and no retake fee is required. There are no scheduling restrictions, but the validity period of the driving skill permit is three years. If the applicant fails to complete the test within the validity period, the passed subjects' scores will be invalidated.

How to Defog Your Car in Winter?

Here are some ways to defog your car in winter: 1. If the speed is not too fast, you can use air convection: Open a small gap in the car window to allow air convection between the inside and outside of the car. After a while, the fog on the inner glass will dissipate. 2. Use a car-specific anti-fog spray: Before using the anti-fog spray, first clean the inside of the front windshield, then spray an appropriate amount of the anti-fog spray. After the spray solidifies, wipe it clean with a clean towel. The anti-fog spray forms a water-repellent layer between water molecules and the inner surface of the glass, keeping the glass surface clean and preventing fogging. 3. Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog: In summer, especially when multiple people enter the car and the air conditioning is not turned on in time, the humidity from exhaled breath can quickly cause the front windshield to fog up. In this case, turn on the air conditioning to blow cold air toward the front windshield. Using the dehumidifying function of the air conditioning, the fog on the front windshield can be removed quickly.

What does 'Oil Pressure Abnormal, Please Turn Off the Engine' mean?

Oil Pressure Abnormal, Please Turn Off the Engine is a problem with the oil filter check valve. If the oil filter is ruled out, then there is a check valve underneath the oil filter that needs to be replaced. Below is an introduction to the oil pressure regulator: Definition: The oil pressure regulator is essentially a flow-type relief valve controlled by a diaphragm. The diaphragm divides the regulator into an upper spring chamber and a lower fuel chamber. The diaphragm controls the opening of the relief valve to maintain pressure balance between the upper and lower chambers. Working Principle: When the fuel chamber's oil pressure rises above the combined force of the spring pressure and vacuum gas pressure, the diaphragm arches upward, opening the regulator valve. Some fuel flows back to the tank through the return port via the ball valve, reducing the fuel pressure. When the pressure drops to the regulator's set control pressure, the ball valve closes to maintain a certain pressure in the oil circuit from the pump's one-way valve to the pressure regulator.

What are the differences between the Haval Chitu and the Haval First Love?

The differences between the Haval Chitu and the Haval First Love include variations in body dimensions and powertrain. Below are detailed explanations of these differences: Body Dimensions: The Haval Chitu measures 4470mm in length, 1898mm in width, and 1625mm in height, with a wheelbase of 2700mm. Its dimensions are roughly comparable to those of the Haval First Love, positioning it as an entry-level compact SUV. The First Love, on the other hand, measures 4472mm in length, 1841mm in width, and 1619mm in height, with a wheelbase of 2700mm, classifying it as a compact SUV. Powertrain: The Haval Chitu is equipped with a 1.5T engine, available in high and low power tuning versions, delivering maximum power outputs of 184 horsepower and 150 horsepower respectively. It is paired with a 7-speed wet dual-clutch transmission. The Haval First Love also features a 1.5T engine, with a maximum output power of 110kW (150 horsepower), mated to a 7-speed dual-clutch transmission.

When did China IV vehicles start?

China IV emission standards began in 2011 and lasted until the implementation of China V standards in 2018. Therefore, vehicles produced between 2011 and 2017 all comply with China IV standards. The China IV standard requires approximately 50% lower emissions of various pollutants compared to China III. Currently, with China VI standards approaching, vehicles meeting China III emissions are facing mandatory retirement. Here is more information: 1. Different countries and regions adopt varying emission standards based on their actual conditions. For example, the U.S. has U.S. standards, Europe has Euro standards (Euro IV, Euro V, etc.), and China has national standards (China IV, China V, etc.). 2. There are three main test cycles for passenger vehicle emissions: the EU's NEDC cycle, the U.S.'s FTP75 cycle, and Japan's JC08 cycle.

What are the precautions when turning a car?

When turning a car, the steering wheel operation should match the road curvature and coordinate with the driving speed to achieve appropriate steering angle, proper steering timing, and timely direction correction. It is strictly prohibited to take both hands off the steering wheel to prevent dangerous deviation. Below are relevant introductions about car turning: Slow down when turning: Do not turn the steering wheel too sharply to avoid excessive centrifugal force causing the car to skid. If the car skids, immediately release the accelerator pedal and turn the steering wheel toward the side where the rear wheels are skidding. Once the vehicle resumes straight driving, correct the steering wheel and continue driving. Use turn signals at intersections: When turning left, besides changing lanes and activating the turn signal in advance, try to drive closer to the center of the road while waiting to turn to facilitate the passage of following vehicles. When turning right, besides merging into the outer lane in advance, also turn on the right turn signal to alert pedestrians on the roadside. Reduce speed when turning right and be mindful of the impact of the inner wheel difference to avoid scraping pedestrians.

Did traffic lights or cars come first?

From the perspective of whether transportation tools or traffic control signals came first, traffic lights should have preceded vehicles. The origin of traffic lights: The world's first coal-illuminated traffic signal was put into use in London on December 9, 1868. However, its construction and use were originally intended to prevent horse-drawn carriage congestion. This traffic signal combined three arm signals and used red and green gas lamps for nighttime operation, with a police officer operating it via a control lever on the lamp post. The first electric-powered traffic light was developed by an American police officer in 1912, which also only used red and green lights. The origin of automobiles: As for the world's first recognized automobile, it is generally defined by the date when Karl Benz, one of the founders of Mercedes-Benz, obtained the world's first automobile engine patent. This date was January 29, 1886. Therefore, even before the existence of cars, the earliest form of traffic lights had already emerged with the original intention of maintaining orderly traffic and avoiding congestion.
