How Many Times Can You Take the Subject 4 Exam in One Day?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," there is no limit to the number of times you can take the Subject 4 exam. If you fail the first attempt on the same day, you can retake it once on-site. If you still fail, you will need to reschedule the exam. 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 fails to complete the exam within this period, the results of any previously passed subjects will be invalidated. Subject 4 consists of a test paper with 50 questions, primarily in the form of case studies, images, and animations. The maximum score is 100, with a passing score of 90. Subject 4, also known as the theoretical exam for drivers, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and the "safe and civilized driving knowledge" exam, commonly referred to as "Subject 4," which evaluates "driving ethics." Subject 4 is the colloquial term for the safe and civilized driving knowledge exam under Subject 3, not a separate subject. Since this exam is conducted after Subject 3, it is commonly referred to as Subject 4. Officially, there is no Subject 4. The safe and civilized driving knowledge exam is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 45 minutes. Number of Questions: Depending on the type of driving license being pursued, 50 questions are randomly selected from the corresponding Subject 4 question bank, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. The questions may involve animations, images, scenario recognition, or text descriptions. Subject 4 Exam Tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, do not just memorize the correct answer. Instead, refer to regulations, textbooks, or reference materials to understand the underlying reasons for errors. Categorize and summarize questions. Refer to the question bank analysis for classification and identify similar questions. Many questions in the bank are similar and can be confusing, so it is helpful to group them for analysis. For example, traffic signs for walking, pedestrian crossings, and pedestrian warnings have similar patterns and can be easily mixed up. Grouping them during study helps avoid mistakes. Use memory techniques. Many questions in the bank involve numbers, which can be summarized for easier memorization. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the exam on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skills exam. Subject 3 refers to the road driving skills and safe and civilized driving knowledge exam.

What are clearance lights and rear position lights?

Clearance lights and rear position lights are both used to identify the vehicle body, providing a light signal to oncoming and following vehicles. Rear position lights are also called width indicator lights, which include front and rear position lights on the vehicle. Generally, clearance lights are positioned higher than rear position lights. The specific differences between clearance lights and rear position lights are as follows: Clearance lights are warning lights, usually located at the top edges of the front and rear of the vehicle, indicating both the height and width of the car. Safety regulations require that vehicles taller than three meters must be equipped with clearance lights. Rear position lights are mainly used to indicate the presence and approximate width of the vehicle, helping other vehicles judge during overtaking or meeting. These lights are installed at the rear of the vehicle and are red. When the vehicle brakes, the circuit is activated, automatically emitting red light. Rear position lights are commonly found on large vehicles such as buses, coaches, and trucks, with multiple lights on each side. When illuminated at night, they help other vehicles gauge the length and width of the vehicle to avoid accidents. Width indicator lights provide an estimate of the vehicle's width. In rainy or foggy conditions, they inform following vehicles of the vehicle's size and width. There is also a noticeable difference in brightness between clearance lights and rear position lights. Since clearance lights are closely related to driving safety, their brightness is significantly higher compared to front and rear position lights. Classification and Usage Tips for Vehicle Lights Turn signals: Must be turned on when changing direction, flashing intermittently to alert surrounding vehicles and pedestrians. The timing for activating turn signals is crucial—they should be turned on approximately 30 to 100 meters before the turn. Turning them on too early may give the impression of forgetting to turn them off, while turning them on too late may catch following vehicles or pedestrians off guard, leading to mistakes. Headlights: Commonly known as "high beams," headlights are the "heart" of a vehicle's lighting system. Regular checks are essential, and professional workshops can adjust the height and angle of the lights to ensure optimal visibility for the driver. When meeting another vehicle, switch to low beams and revert to high beams afterward to extend visibility. Use alternating high and low beams to signal other vehicles when passing intersections or overtaking. Brake lights: These are highly bright and inform following vehicles that the car ahead is slowing down or stopping. Regular inspection of brake lights is necessary. If damaged, they should be replaced promptly to avoid rear-end collisions, which can cause significant harm to the cervical spine. Fog lights: These should also be checked regularly to ensure they work in case of sudden fog, rain, snow, or emergencies, alerting following vehicles to take timely action. Drivers must use fog lights in foggy conditions—small lights cannot substitute them. Using rear fog lights in non-foggy conditions can impair the vision of following drivers and is unsafe. Emergency hazard lights: Many drivers rarely use emergency hazard lights (hazard flashers). These should be activated when the vehicle breaks down and needs to stop temporarily or in emergencies. They should also be turned on in poor visibility conditions. Regular checks are necessary to ensure they function properly.

What Causes a Car to Lose Power Over Time?

Car losing power over time may be due to insufficient engine power. Here are the specific reasons: 1. Unreasonable increase in external load: For example, "brake drag" caused by brake system failure. Therefore, when noticing insufficient engine power, reduced speed, and poor acceleration, the first step is to analyze and identify external influencing factors. After eliminating external factors, proceed to investigate internal causes. 2. Improper installation or adjustment of the throttle pedal and linkage: Due to incorrect installation or adjustment of the throttle linkage, the governor load control lever cannot be pushed to the full-load position, thereby affecting the engine's power output.

Where to Look When 50 cm Away from the Side Car?

Sit inside the car and find a reference point according to your own habits to locate a suitable spot. Additional information is as follows: 1. Introduction: A safe following distance refers to the necessary gap maintained by a trailing vehicle to avoid accidental collisions with the vehicle ahead while driving. Maintaining a safe distance is the most direct, effective, widespread, and fundamental method to prevent rear-end collisions. 2. Measurement Standard: There is no absolute standard for a safe following distance, only dynamic standards. The most direct and significant factor affecting the safe distance is speed. When the speed increases, the required braking force, braking distance, and the distance traveled at the original speed during the reaction time all increase accordingly. Maintaining a safe distance requires controlling the speed.
