Can I Take Subject Four After Passing Subject One?

After passing Subject One of the driver's license test, you cannot directly take Subject Four. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the examination sequence proceeds as Subject One, Subject Two, and Subject Three in order. Only after passing the previous subject can you proceed to the next. After passing the road driving skills test of Subject Three, you are eligible to take the safe and civilized driving knowledge test. The driving test consists of three subjects: Subject One, Subject Two, and Subject Three, with Subject Three divided into two parts. Subject Four is the colloquial term for the safe and civilized driving knowledge test under Subject Three and is not a separate subject. Subject One refers to the test on road traffic laws, regulations, and related knowledge; Subject Two refers to the field driving skills test; Subject Three refers to the road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after Subject Three. Each subject test 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 current test session ends, and the applicant must reschedule the test. However, Subject Two and Subject Three tests must be rescheduled at least ten days later. If you fail the safe and civilized driving knowledge test of Subject Three, the passed road driving skills test results remain valid. Within the validity period of the driving skills test permit, the number of rescheduled tests for Subject Two and Subject Three road driving skills tests must not exceed five. If you fail the fifth rescheduled test, the passed results of other subjects become invalid. Subject Four Test Notes: Test Duration: The test lasts 30 minutes, and if you make 12 mistakes (6 questions) during the test, the session ends immediately. Number of Questions: Depending on the type of driver's license, 50 questions are randomly selected from the corresponding Subject Four question bank. For car licenses, questions are selected from 800, and for large vehicle licenses, from 1023. Each question is worth 2 points. Question Types: The test includes single-choice questions (including true/false questions) and multiple-choice questions. The first 45 questions are single-choice, and the last 5 are multiple-choice. The test also includes animation questions, image questions, scenario recognition questions, and text-based questions. Retest Notes: If you fail Subject Four, you only need to retake Subject Four. The driving school will schedule the retest, and there is no limit to the number of retakes. You can retake it until you pass, and no retest fee is required for Subject Four. Subject Four Test Tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, do not just memorize the correct answer. Refer to laws, textbooks, or reference books to understand the reasons behind the mistakes and internalize them. Categorize and summarize questions. Refer to the question bank analysis to group similar questions. Many questions in the bank are similar and easily confused, so they should be analyzed together. For example, traffic signs like "Pedestrian," "Walking," "Pedestrian Crossing," and "Caution: Pedestrian Crossing" have similar patterns and can be confusing. Grouping them during study helps avoid mistakes. Find memory techniques: Many questions in the bank involve numbers. Summarizing these numbers makes them easier to remember.

How to Distinguish Between Good and Bad Car Window Tinting?

Methods to distinguish between good and bad car window tinting are: 1. From the clarity perspective, regardless of the darkness of the tint, a good film should allow clear visibility of objects beyond 6 meters at night, while a bad film will have a foggy appearance; 2. From the touch perspective, a good film feels thick and smooth, whereas a bad film feels thin and brittle, prone to wrinkling; 3. From the color perspective, the pigment in a good film is evenly integrated into the film and will not fade when scraped during the application process, while the color in a bad film is in the adhesive layer, and the color will come off when scratched with a fingernail after peeling off the film's inner lining. Car window tinting involves applying a thin film-like object to the front and rear windshields, side windows, and sunroof of a vehicle, and this film is also known as a solar film or heat-insulating film.

What does the P gear in an automatic transmission stand for?

Automatic transmission P gear is the abbreviation for parking gear, which utilizes the vehicle's parking brake mechanism to halt rotation. Typically, an automatic transmission has six gear positions: P gear is the parking gear, R gear is the reverse gear, N gear is the neutral gear, D gear is the drive gear, S gear is the climbing gear, and L gear is the low-speed gear. An automatic transmission eliminates the need for manual gear shifting by the driver, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. The engine's power is transmitted through the gearbox, which is also a critical factor affecting fuel consumption. Generally, automatic transmissions consume over 10% more fuel than manual transmissions.

How to Check the Tire Pressure of Haval F7?

To check the tire pressure of the Haval F7, press and hold the OK button for five seconds, then use the up and down adjustment buttons to navigate to the tire pressure display interface. Tire pressure should neither be too high nor too low. If the tire pressure is too low, the tires may experience wave-like deformation during high-speed driving, increasing the risk of a blowout. Conversely, if the tire pressure is too high, it reduces the contact area between the tires and the ground, negatively affecting the vehicle's grip and handling stability. The Haval F7 measures 4620mm in length, 1846mm in width, and 1690mm in height, with a wheelbase of 2725mm. The front and rear track widths are both 1585mm. Its engine delivers a maximum horsepower of 169Ps, a maximum power output of 124kW, and a maximum torque of 285Nm.
