When the gear is within the normal range, maintaining 3500 RPM while driving on highways will not damage the car. Here are the specific details: Introduction: Generally, for household vehicles, the RPM fluctuates between 2500-3500 when driving at 120 km/h, though this may vary across different models. Some models can even maintain speeds below 2000 RPM. When driving on highways, it is advisable not to turn off the engine immediately upon entering a service area. Instead, let the engine idle for about five minutes before shutting it down to allow sufficient cooling and prevent potential engine issues. RPM-Gear Comparison Table: When the transmission is in 5th gear, reaching 120 km/h typically requires nearly 4000 RPM; in 6th gear, it takes around 3000 RPM to achieve the same speed; and in 7th gear, the vehicle can exceed 120 km/h at just 3000 RPM.

What is the content of the Subject 4 driving license test?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses", the Subject 4 test consists of 50 questions, primarily in the form of case studies, pictures, and animations, with a full score of 100 and a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driving 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 safety and civilization knowledge test, commonly referred to as Subject 4. It is not a separate subject but is called Subject 4 because it is conducted after Subject 3. Officially, there is no Subject 4. The safety and civilized driving knowledge test is conducted after Subject 3. There is no limit to the number of times you can take the Subject 4 test. If you fail the first test on the same day, you can retake it on the spot. If you still fail, you need to reschedule the test, and no additional fees are required for retakes. However, it is important to note that the validity period of the driving skill test permit is three years. If the applicant does not complete the test within the validity period, the results of the already passed subjects will be invalidated. Subject 4 test considerations: Test duration: The test lasts 45 minutes, and if you answer 10 points (5 questions) incorrectly during the test, the session will be terminated. Number of questions: Depending on the type of driving license being tested, 50 questions are selected proportionally from the corresponding Subject 4 question bank, with each question worth 2 points. Question types: The test includes single-choice questions (including true/false questions) and multiple-choice questions, with questions presented as animations, pictures, scenario recognition, and text descriptions. Retake considerations: If you fail Subject 4, you only need to retake Subject 4. The driving school will schedule the retake, and there is no limit to the number of retakes. You can retake it continuously until you pass, and no additional fees are required for Subject 4 retakes. Subject 4 test tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, do not just look at the correct answers and memorize them. Refer to regulations, textbooks, or reference books to find out the reasons for the mistakes and understand them. Categorize and summarize the questions. You can refer to the question bank analysis for categorization and find similar questions: Many questions in the bank are similar and can be confusing, so they should be analyzed and summarized. For example, traffic signs for walking, hiking, pedestrian attention, crosswalks, and crosswalk attention have very similar patterns and can be confusing. During study, categorize them to avoid mistakes. Find memory techniques: Many questions in the bank involve numbers, which can be summarized for easier memorization. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the test on road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safety and civilized driving knowledge test.

What are the reasons for windshield wipers not spraying water?

The reasons for windshield wipers not spraying water are: 1. The wiper nozzle is clogged or the pipeline is detached. It is recommended to check the spray nozzle; 2. The fuse is blown and needs to be replaced. The power source of the wiper comes from the motor, which is the core of the entire wiper system.
