How many subjects are required for the driving test?

The driving test consists of four subjects. The content and passing standards of the test subjects are uniformly regulated nationwide, and the test sequence follows Subject 1, Subject 2, Subject 3, and Subject 4 in order. Only after passing the previous subject can one proceed to the next. The details are as follows: 1. Subject 1: Road traffic safety laws, regulations, and related knowledge test. The structure and basic question types of the test question bank are formulated by the Ministry of Public Security, while provincial traffic management departments under the public security authorities establish the test question bank for their respective provinces (autonomous regions, municipalities) based on local conditions. 2. Subject 2: Field driving skills test, including test items such as reversing into a garage, stopping and starting on a slope, turning at a right angle, driving along a curve, and parallel parking. 3. Subject 3: Road driving skills test, including basic test items such as preparation before driving (walking around the vehicle counterclockwise, fastening the seatbelt, turning on the left turn signal, shifting gears, releasing the handbrake, and honking), starting, driving straight, changing lanes, passing through intersections, parking by the roadside, crossing pedestrian crosswalks, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and driving at night. 4. Subject 4: Safe and civilized driving knowledge, covering test items related to safe and civilized driving.

What to Use for Cleaning Car Interiors?

When cleaning by yourself, pay attention to selecting different cleaning agents and auxiliary tools according to different parts. The specific contents of car interior cleaning are as follows: Cleaning the car center console: Use cleaning soft gel. For hard-to-reach gaps, cleaning gel can solve this problem. Cleaning door interiors: Cleaning liquid and towel. The cleaning agent can dissolve dirt on the door, and then wipe it off with a towel, which works quite well. Cleaning the car ceiling interior: Cleaning agent and brush. Spray the cleaning agent, then scrub with a brush, and finally wipe off the water with a towel. Steering wheel cleaning: Cleaning foam and towel. Since the steering wheel is made of leather, using foam cleaning can avoid damaging the leather material, with good results. Leather seat cleaning: Cleaning foam and towel. Seats are the most frequently used areas, so foam cleaning allows for deeper cleaning and is also easier to wipe off. Cleaning dust and debris inside the car: Car vacuum cleaner. The vacuum can quickly and effectively suck away debris from corners or gaps, especially fine sand and mud brought in by shoes, which is very effective.

What is the correct way to use an exhaust brake?

An exhaust brake (commonly known as an exhaust retarder) is a type of auxiliary braking device that functions as a secondary brake. Its purpose is to reduce or maintain vehicle speed without or with minimal use of the service brakes, although it cannot bring the vehicle to an emergency stop. Proper use of the exhaust brake can significantly reduce reliance on service brakes, thereby minimizing wear on brake pads (or discs) and greatly lowering the risk of overheating due to continuous braking, which could compromise driving safety. Key considerations for using an exhaust brake are as follows: 1. It is an auxiliary brake: The exhaust brake serves as a supplementary braking mechanism and cannot replace the service brake for emergency stops or be used as a parking brake. However, it can be used in conjunction with the service brake. 2. Preventing engine stalling when stopping: When the exhaust brake is engaged, the throttle pedal should be at zero position, and the fuel injectors stop injecting fuel. If the accelerator or clutch pedal is pressed, the exhaust brake will automatically disengage, preventing engine stalling when stopping and avoiding exhaust brake activation during fuel injection. 3. Engine exhaust braking power depends on engine speed: For optimal braking performance, when using the exhaust brake on long downhill slopes, select an appropriate gear (the transmission should not be in neutral) to keep the engine speed between 1600-2400 rpm. At lower engine speeds, the braking effect is limited, and it is advisable to shift to a lower gear or use conventional service brakes.

Can a Car Designed for 92 Octane Use 95 Octane?

A car designed to use 92 octane gasoline can occasionally be filled with 95 octane gasoline, but it should not be used for an extended period. Below are the consequences of using fuel that does not match the engine's requirements: 1. Using lower octane fuel in a high-compression engine can lead to reduced power output and damage to engine components. 2. Using higher octane fuel in a low-compression engine can cause incomplete combustion and also damage engine components. Here is additional information about gasoline grades: 1. The octane rating of gasoline is determined by its Research Octane Number (RON). For example, 92 octane gasoline has a RON of at least 92. The choice of gasoline grade for an engine primarily depends on whether the compression ratio matches the gasoline's octane rating. 2. The terms 92, 95, and 98 octane unleaded gasoline refer to fuels containing 92%, 95%, and 98% of "isooctane," which has strong anti-knock properties, and 8%, 5%, and 2% of "n-heptane," which has poor anti-knock properties, respectively.

What to Do After Stalling in Subject 2?

After stalling in Subject 2, it's important to stay calm and not panic. Restart the engine by shifting the transmission lever back to neutral before starting the car. Once the engine starts, promptly release the key to avoid affecting the starting performance. Subject 2 is a field driving skills test, which includes tasks like reversing into a garage and parallel parking. The driver's license examination is a standardized test nationwide for obtaining a motor vehicle driver's license, consisting of four subjects: road driving performance and knowledge of civilized driving. Upon passing all four subjects, one can receive a motor vehicle driver's license. Individuals aged 18 or older are eligible to take the test.
