Can I retake the test immediately if I score 86 in Subject 4?

You can retake the test on the same day. If you fail both attempts, you can apply for a retest after 10 days. There is no limit to the number of retakes, and each attempt provides two opportunities. Subject 4, also known as the theoretical test or driver's theory test, is part of the motor vehicle driver's license examination. The test consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing score of 90. Below is an introduction to other test subjects: 1. Subject 1: Also known as the theoretical test or driver's theory test, it is part of the motor vehicle driver's license examination. The test content includes driving theory basics, road safety laws and regulations, and local regulations. The test format is computer-based, with 100 questions, and a passing score of 90 or above. 2. Subject 2: Also known as the small road test, it is part of the motor vehicle driver's license examination and refers to the field driving skills test. For small cars (C1, C2), the test items include five mandatory components: reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-curves). 3. Subject 3: Includes the road driving skills test and the safety and civilized driving knowledge test. It is part of the motor vehicle driver's license examination and refers to the road driving skills and safety and civilized driving knowledge test. The content of the road driving skills test varies depending on the type of vehicle license.

How to use lights when entering the deceleration lane on a highway?

When entering the deceleration lane on a highway, you should turn on the right turn signal. The following is an introduction to highway knowledge: 1. Definition: A highway, also known as an expressway, refers to a road specifically designed for high-speed vehicle travel. Highways have different regulations in different countries and regions, different eras, and various scientific research and academic fields. 2. Service facilities: Along the highway, service areas are set up approximately every 50 kilometers, equipped with gas stations, parking lots, rest areas, restaurants, restrooms, and auto repair shops. Service areas are important supporting facilities within the highway system, providing necessary safety guarantees for long-distance driving.

What are the advantages and disadvantages of an intake supercharger pump?

The advantage of an intake supercharger pump is its simple maintenance, while the disadvantage is its short lifespan. Below is an introduction to the knowledge about intake supercharger pumps: 1. Advantages of an intake supercharger pump: The pump has fewer parts and seals, making maintenance simple and cost-effective. Additionally, it features high output performance at a low cost. 2. Disadvantages of an intake supercharger pump: High-pressure superchargers indefinitely reduce the diameter of the steel wheel in the turbine housing flow path, causing the supercharger to operate at excessive speeds continuously. The average speed exceeds that of ordinary superchargers by 20,000 to 30,000 RPM. The lifespan of a high-pressure supercharger is only two-thirds that of a standard supercharger, and the lifespan of high-pressure superchargers from smaller manufacturers is even shorter.

What is the rightmost lane on the highway called?

The rightmost lane on the highway is called the driving lane, with a speed limit of 60-90 km/h. The leftmost lane is the overtaking lane, with a speed limit of 110-120 km/h, while the middle lane is also a driving lane, with a speed limit of 90-110 km/h. Below are some precautions for driving on highways: 1. Check the car before entering the highway: Inspect the car's braking system, tire pressure, and wear before entering the highway to avoid emergency braking failure. Both underinflated and overinflated tires are unsafe for high-speed driving and can easily lead to blowouts, which can be fatal at high speeds. Therefore, thorough vehicle inspection is essential. 2. Fasten seat belts: Seat belts should be worn whether driving on regular roads or highways. Rear passengers should also fasten their seat belts during high-speed driving. 3. Drive in the designated lane: Highways have clearly marked lanes for large vehicles, small vehicles, etc. After overtaking, promptly return to your designated lane and avoid occupying other lanes for extended periods. Additionally, the emergency lane should not be occupied without special reasons. 4. Maintain a safe speed and avoid speeding: The dangers of speeding are well-known and can lead to irreversible consequences, whether on local roads or highways. 5. Be cautious when overtaking: Exercise caution when overtaking on highways. Always use turn signals before overtaking and use the overtaking lane. Avoid the bad habit of overtaking from the right. After signaling, check the rear traffic conditions before overtaking. When conditions permit, accelerate and maintain a lateral distance of about 1.5 meters from the vehicle ahead. Leave sufficient distance to merge back into the driving lane after overtaking to avoid rear-end collisions. 6. Maintain a safe following distance: Under normal conditions with dry roads and good brakes, the following distance (in meters) should not be less than the speed (in km/h). For example, at 80 km/h, maintain at least 80 meters; at 100 km/h, maintain at least 100 meters. Always pay attention to roadside distance markers. In rainy, foggy, snowy, or wet conditions, double the following distance. 7. Observe traffic signs: Always watch for roadside and overhead signs and markings, and drive slightly to the right to avoid crossing the right lane divider, providing enough lateral distance for overtaking vehicles. 8. Do not occupy the emergency lane unnecessarily: Traffic accidents can happen on highways. If other vehicles cause blockages, avoid occupying the emergency lane, as it may hinder rescue vehicles. 9. Avoid fatigue driving and take breaks: Fatigue driving is extremely dangerous on highways. Fatigue reduces reaction time, making it difficult to respond correctly to emergencies.

Can the speedometer indicate the grade of a car?

The speedometer cannot indicate the grade of a car. It can only be said that high-performance cars generally have larger maximum speed readings on the dial, but cars with large maximum speed readings are not necessarily high-performance. Car manufacturing follows a modular approach, meaning speedometers are not exclusively selected for certain performance models. As a result, multiple car models may share the same speedometer, making it impossible to conclude that a larger maximum speed reading directly correlates with better car performance. Below is an introduction to the car's central control system: 1. Central locking system: There are many types of central locks installed in cars, but their basic components mainly include door lock switches, door lock actuators, and door lock controllers. 2. Switches: Most central lock switches consist of a master switch and individual switches. The master switch is located on the driver's door, allowing the driver to lock or unlock all doors in the car. Individual switches are installed on other doors, enabling independent control of a single door. 3. Actuators: The central lock actuator is used to execute the driver's commands to lock or unlock the doors. Door lock actuators come in three types: electromagnetic, DC motor, and permanent magnet motor. Their structures all involve changing polarity to reverse the direction of movement, thereby executing the locking or unlocking action.
