How Many Days After Booking the Subject 2 Test Will the Exam Take Place?

After successfully booking the Subject 2 test, the exam can be scheduled no earlier than 10 days after obtaining the study driving permit. Here are the relevant details: 1. Regulations: According to Article 40 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," for first-time applicants or those applying to add a permitted vehicle type, the following rules apply when booking the Subject 2 test: Applicants for small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, small automatic transmission passenger cars for the disabled, wheeled self-propelled machinery, trolleybuses, or tram permitted vehicle types can schedule the exam no earlier than 10 days after obtaining the study driving permit. Applicants for large buses, tractors, city buses, medium-sized buses, or large truck permitted vehicle types can schedule the exam no earlier than 20 days after obtaining the study driving permit. 2. Notes: In areas where conditions permit, applicants can simultaneously book the Subject 2 and Subject 3 road driving skill tests. If the booking is successful, the exams can be taken consecutively. After passing both the Subject 2 and Subject 3 road driving skill tests, applicants can take the Subject 3 safe and civilized driving knowledge test on the same day.

What is the Difference Between Commercial Vehicles and Passenger Vehicles?

Passenger vehicles and commercial vehicles have significant differences. The following is a detailed introduction: 1. Passenger vehicles: Refer to cars and vehicles primarily designed for carrying passengers with no more than 9 seats, including SUVs, MPVs, racing cars, and household pickup trucks. Commercial vehicles, on the other hand, refer to all trucks, special-purpose vehicles, military vehicles, engineering vehicles, buses with more than 9 seats, as well as tractors, agricultural vehicles, and mining vehicles. Passenger vehicles are designed and technically characterized mainly for transporting people and their luggage or occasionally goods, with a maximum of 9 seats, including the driver. 2. Commercial vehicles: Commercial vehicles are designed and technically characterized for transporting people and goods. Since 2005, China's automotive industry has implemented a new statistical classification for vehicle types. Compared to the old classification, commercial vehicles include all trucks and buses with more than 9 seats. In China, vehicles are classified into several categories: trucks, off-road vehicles, dump trucks, tractors, special-purpose vehicles, buses, passenger cars, spare classification numbers, and semi-trailers. Among these, trucks, buses, and passenger cars are the three most common types of vehicles.

What is the correct procedure for warming up a car while stationary?

The correct procedure for warming up a car while stationary is as follows: Start the engine and let it idle for about one minute before beginning to drive slowly. Once the coolant temperature reaches the normal operating range, you can proceed with normal driving. Additional information about stationary warm-up is provided below: 1. Stationary warm-up refers to idling the engine while parked. For manual transmission vehicles, shift to neutral and engage the parking brake. For automatic transmission vehicles, engage the parking brake and you may shift to P (Park) or N (Neutral). 2. During stationary warm-up, avoid using any electrical accessories except for the rear window defroster to prevent overloading the battery. 3. Do not use the heater for defrosting during stationary warm-up. The heater won't produce warm air at this stage, and it will only prolong the warm-up time while further burdening the battery. 4. Avoid pressing the accelerator pedal aggressively during stationary warm-up. Since lubrication is inadequate immediately after startup, revving the engine can lead to increased wear. Moreover, the timing chain tensioner may not be fully engaged right after startup, and aggressive throttle input could cause the timing chain to skip teeth, resulting in timing misalignment that would require engine disassembly for repair.

What are the effects of high and low oil viscosity on car engines?

Oil viscosity has the following effects on car engines: 1. If the engine oil viscosity is too high, the resistance during engine operation increases, leading to higher fuel consumption, and the engine speed rises relatively slowly after pressing the accelerator. 2. If the engine oil viscosity is too low, it cannot form a stable oil film on the surface of various components during engine operation, resulting in poor lubrication. Below is extended information on the effects of oil viscosity on engines: 1. If the oil viscosity is too high, the oil film becomes too thick, increasing resistance due to oil viscosity and causing adverse effects. The car becomes harder to start and accelerates sluggishly. Engine power output decreases, and cooling efficiency worsens. The car consumes more fuel, leading to wastage. Due to poor oil fluidity, it cannot quickly reach the cylinders, increasing wear during startup. 2. If the oil viscosity is too low, it also adversely affects the engine. The oil film thickness is insufficient, and the oil film strength is weak, making it easily disrupted. It is difficult to form a sufficiently thick oil film on high-temperature, high-pressure friction surfaces, preventing normal lubrication and causing excessive engine wear. The sealing effect is poor, and low oil viscosity leads to inadequate piston ring sealing, directly causing combustion chamber blow-by and oil burning. Engine noise increases.

Can You Stop During Subject 2 of the Driving Test?

During the Subject 2 driving test, stopping midway is not allowed. According to the scoring criteria, stopping midway results in a failing grade. Here are the relevant details: 1. Deduction Rules: Not following the prescribed route sequence results in a 100-point deduction; failing to completely reverse into the parking space results in a 100-point deduction; the vehicle body crossing the line results in a 100-point deduction; stopping midway results in a 100-point deduction (previously, examinees could stop before entering the parking space, but once GPS positioning confirms the vehicle is in a complete stop, the examinee will be directly deducted 100 points). 2. Important Notes: After getting into the car, quickly adjust the seat, rearview mirrors, and fasten the seatbelt. Once everything is ready, verify your fingerprint and follow the voice prompts to enter the designated test lane. Each test item in the examination area is monitored by GPS positioning, and the control line (yellow dashed line) for each item represents the test area for that item. Once the front of the vehicle crosses the control line, it means you have entered the test for that item and must complete the test according to the rules of that item.

If I fail midway during Subject 2, should I continue to the next item?

If you hear the announcement of failure midway through Subject 2, regardless of which item you are currently on, you can only drive the car back to the starting point and begin the test again from the first item. You have two chances, and passing either one means you qualify. Remember to collect your score sheet at the exit to confirm your qualification. Here are the relevant details: 1. Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the field driving skills test. For small cars (C1/C2), the test items include five mandatory items: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-curves). Some regions may have a sixth item, high-speed card collection. 2. Passing criteria: The full score is 100 points, with evaluation standards set for failure, minus 20 points, minus 10 points, and minus 5 points. The following regulations apply for passing: For large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 is required; for other vehicle types, a score of 80 is required.
