What is a C9 driver's license?

C9 is not a driver's license classification; it refers to the C9 League (a group of nine prestigious universities in China). Below are specific details about driver's license classifications: 1. According to the "Motor Vehicle Driver's License Business Regulations" issued by the relevant authorities, China implements a tiered driver's license system, dividing licenses into 15 categories: A1, A2, A3, B1, B2, C1, C2, C3, C4, D, E, F, M, N, and P. 2. The permitted vehicle types for each license category are as follows: a. A1 license: Permits driving large passenger vehicles; b. A2 license: Permits driving tractor units, heavy and medium-duty full trailers, and semi-trailer combinations; c. A3 license: Permits driving urban buses with a capacity of 10+ passengers; d. B1 license: Permits driving heavy passenger vehicles; e. B2 license: Permits driving heavy and medium-duty trucks; f. C1 license: Permits driving small and mini passenger vehicles; g. C2 license: Permits driving small and mini automatic transmission passenger vehicles; h. C3 license: Permits driving low-speed trucks (formerly four-wheel agricultural transport vehicles); i. C4 license: Permits driving three-wheeled vehicles (formerly three-wheel agricultural transport vehicles).

What are the speed limits for two-lane, three-lane, and four-lane roads?

Regardless of the number of lanes, the basic speed limit regulations are a minimum of 60km/h and a maximum of 120km/h. Depending on the number of lanes, the specific limits are as follows: for two lanes, the left lane has a minimum of 100km/h and the right lane a minimum of 60km/h; for three lanes, the left lane has a minimum of 110km/h, the middle lane a minimum of 90km/h, and the right lane a minimum of 60km/h; for four lanes, the far left lane is 110km/h, the second left lane is 100km/h, the third left lane is 90km/h, and the far right lane is 60km/h. No matter which lane, the maximum speed is not allowed to exceed 120km/h. Highways are classified as high-grade roads. Although different countries have different names for highways, they all refer to roads with more than four lanes, separated directions, fully controlled access points, and all using grade-separated interchanges. Generally, highways are designed to accommodate speeds of 120km/h or higher, with road widths of more than four lanes. A median divider is set up in the middle, using high-grade pavement materials like asphalt concrete or cement concrete, equipped with complete signage, markings, signals, and lighting devices; pedestrians and non-motorized vehicles are prohibited from using the road, with other routes accessed via grade-separated interchanges, pedestrian overpasses, or underpasses.

Are there multiple-choice questions in the driving license theory test (Subject 1)?

The driving license theory test (Subject 1) includes multiple-choice questions, divided into single-choice questions and true/false questions. There are 100 questions in total, with each question worth 1 point, making a total score of 100. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," if you answer 11 questions incorrectly during the test, the system will automatically submit the test and end the exam. Subject 1, also known as the theoretical driving test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes the theoretical basis of driving, road safety laws and regulations, local regulations, and other related knowledge. The test is conducted on a computer, with a time limit of 45 minutes. Subject 1 test content: Driving license and motor vehicle management regulations; Road traffic conditions and regulations; Road traffic safety violations and penalties; Road traffic accident handling regulations; Basic knowledge of motor vehicles; Local regulations; Knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; Special knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: During the test, candidates should pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in a locker before entering the examination room. Inside the examination room, the identity verification desk will assign a seat. Once seated, begin the test, ensuring the camera is properly aligned and adhering to test discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score report and sign it—unsigned reports are considered invalid. There is no limit to the number of times you can reschedule the Subject 1 test. Each subject can be taken once, with one retake allowed if you fail. If you do not take the retake or fail it again, the test session ends, and you must reschedule. In contrast, Subject 2 and Subject 3 have only five attempts each. Subject 2 and Subject 3 tests can be rescheduled after ten days. If you fail the Subject 3 safety and civilized driving knowledge test, the passing score for the road driving skills test remains valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safety and civilized driving knowledge. The safety and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as Subject 4.

What does it mean when the ESP system is activated?

ESP system activation refers to the computer's self-check. Below are specific details about the ESP system: 1. The Electronic Stability Program (ESP) is a type of traction control system. 2. Within seconds after startup, the computer performs a self-check, and all indicator lights, including the fault light, will illuminate. The self-check lasts only a few seconds before the lights turn off. If any light remains on, it is advisable to visit a 4S store for inspection. 3. The ESP system is essentially a traction control system. Unlike other traction control systems, ESP controls not only the drive wheels but also the non-drive wheels. For example, in rear-wheel-drive vehicles that often experience oversteer, where the rear wheels lose control and cause the car to fishtail, ESP will brake the outer front wheel to stabilize the vehicle. In cases of understeer, ESP will brake the inner rear wheel to correct the trajectory. 4. The ESP system is a crucial component in a vehicle, typically supporting the functions of ABS and ASR. It analyzes data from various sensors about the vehicle's driving state and issues corrective commands to ABS and ASR to help maintain dynamic balance. ESP ensures optimal stability under various conditions, particularly in situations of oversteer or understeer. The system generally requires the installation of steering sensors, wheel sensors, slip sensors, and lateral acceleration sensors. 5. In addition to utilizing the wheel speed sensors and hydraulic modulators from ABS and TCS, ESP also includes an integrated lateral acceleration sensor, yaw rate sensor, and steering angle sensor. These sensors are responsible for measuring the vehicle's rotational movement around its vertical axis and recording the driver's steering intentions. The wheel speed sensors measure the instantaneous speed of the wheels, while the steering angle sensor records the driver's steering input. The yaw rate sensor and lateral acceleration sensor measure the vehicle's rotational movement around its vertical axis and centrifugal forces.

What is the phenomenon of a sedan driving on the road?

Cars driving on the road belong to the phenomenon of rotation. The following are precautions for driving on the road: 1. Maintain a safe distance from the vehicle in front: Develop the habit of keeping a safe distance from the vehicle in front. If you encounter a car on the adjacent lane suddenly changing lanes without signaling, you will have sufficient distance to respond calmly. 2. Avoid driving at night: The biggest trouble brought by darkness is visual impairment, so try to avoid driving at night. 3. Other precautions: Turn signals must be used when turning or changing lanes, and always check the rearview mirror before slowing down or turning.
