Tire 101W represents the load index and speed rating of the tire. 101 indicates a maximum load capacity of 825kg, and W means the maximum speed should not exceed 270km/h. Speed rating: The speed rating refers to the maximum speed a tire can achieve under specified load and inflation pressure standards. Load index: The load index indicates the maximum load capacity of a single tire under specified conditions. Here is a partial introduction to tires: 1. Tires are classified by usage, including load-bearing tires, passenger car tires, and mining tires, among others. Load-bearing tires must not only have the size specifications marked on the sidewall but also indicate the ply rating. 2. The ply rating of load-bearing tires does not refer to the actual number of layers but rather to the load performance of tires made with high-strength material cords, which is equivalent to the number of cotton cord layers in tires made with cotton cords.

What is the impact of seat height on reference points in Subject 2?

Subject 2 seat height mainly affects the timing of operations. After adjusting the seat, the reference points will change, which significantly impacts Subject 2 performance. Maneuvers such as hill starts, right-angle turns, S-curve driving, reverse parking, and parallel parking all rely on reference points. Generally, if the seat is raised, the timing of each operation needs to be delayed; if the seat is lowered, the timing can be adjusted earlier. It is recommended to fix a position when learning to drive and adjust it to a familiar and comfortable position during practice. When candidates begin the Subject 2 test, they should first adjust the seat so that there is at least a fist's distance between the head and the roof of the car. It is essential to remember the number of notches moved forward or backward, and the backrest must be at a 90-degree angle to the seat. The distance between the top of the head and the car roof can be measured with fingers or tools. When the foot presses the brake pedal to the deepest point, the leg should still have a slight bend, indicating the seat's optimal position.

Is the driving test fee paid by oneself?

Driving test fees are paid by the driving school. The fee you pay when registering at the driving school already includes the examination fee. All subsequent fees are already covered and are fully handled by the driving school. However, retake fees are not included and require separate scheduling. Below is the detailed information: 1. Driving school registration time: Registering for a motor vehicle driver's license at a driving school takes about half an hour to complete. After registration, wait for the driving school's notification for a medical examination. Once the medical examination is completed, proceed with the study for the driver's license theory test (Subject 1). After completing the required study hours, you can take the test. Other test subjects must be completed in the same order. The medical examination does not need to be repeated within six months. 2. Time to obtain a motor vehicle driver's license: Under normal circumstances, it takes about 45 days to obtain a motor vehicle driver's license, with a maximum time limit of three years starting from the completion of the Subject 1 test. If the time limit is exceeded, the qualification for the driver's license test will be canceled, and you will no longer be able to take the test.

How many days after failing the subject 2 test can you schedule a retake?

If you fail the subject 2 test, you need to wait 10 days before you can schedule a retake. For the subject 2 test, if you fail the first attempt, you are allowed one retake. However, if you do not take the retake or fail the retake, the current test session ends, and the applicant must schedule a new test after 10 days. Within the validity period of the driving skills test permit, the number of times you can schedule the subject 2 and subject 3 road driving skills tests cannot exceed five. If you fail the fifth scheduled test, the passing scores of other subjects you have already passed will be invalidated. Passing criteria for subject 2: The full score is 100 points, with evaluation standards set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: For large buses, tractors, city buses, medium buses, and large trucks, a score of 90 or above is required; for other vehicle types, a score of 80 or above is required.

Why Does the Exam Car Stall Easily?

The reason why the exam car stalls easily is that the clutch pedal is lifted too quickly, and the vehicle's throttle is not pressed in time, increasing the engine load and causing the stall. During the motor vehicle driver's license test, it is essential to pay attention to lifting the clutch pedal slowly to ensure the normal power output of the vehicle's engine and avoid stalling. The clutch pedal of a motor vehicle is the control device for the manual transmission car's clutch assembly, serving as the human-machine interface for the driver. When operating the vehicle, the clutch pedal must be used. The quality of clutch pedal control is closely related to the vehicle's driving performance. Therefore, drivers must learn to operate the clutch correctly during practice. Additionally, if the car lacks sufficient power and the examinee reacts too slowly, it is advisable to park in first gear on a slope. When starting, quickly press the clutch to shift gears while simultaneously accelerating to prevent rolling back. To avoid stalling, sufficient speed and power are required. One of the most likely causes is that the handbrake is not fully released, leading to frequent stalling. If this possibility is ruled out, the issue may lie with the car's clutch. In such cases, the examinee can request the examiner for a vehicle change.

Does Fuel from Small Gas Stations Affect Cars?

If the fuel from a small gas station meets quality standards, it will not affect the car. However, if the gas station is unregulated and the fuel quality is poor, it can cause severe damage to the car's engine. Below are the effects of poor fuel quality on a car: 1. Oil Burning: Poor fuel quality leads to incomplete combustion, resulting in excessive carbon deposits. Over time, these deposits accumulate and thicken, with some entering the pistons, causing piston ring sticking and oil return port blockage. This creates gaps in the engine, allowing oil to enter the combustion chamber and burn, leading to oil burning. 2. Reduced Power: Low-quality fuel often results in incomplete combustion, leaving carbon residues that reduce engine power.

Can I make another appointment if I miss the scheduled exam for Subject 1?

If you miss the scheduled exam for Subject 1, you can make another appointment. However, you need to resubmit the registration fee before scheduling the exam again. After missing the exam, the vehicle management office's system requires approximately ten working days to record the results, including the absence. After this period, you can log in to the 12123 Traffic Management APP to reschedule. If the system hasn't updated after ten working days, you can contact the driving school or local vehicle management office for assistance. The key to successfully scheduling Subject 1 is to choose a test center with more available slots. For any subject, there are two scheduling methods: letting the system arrange the exam or selecting the session manually. The system-assigned option has a higher success rate because it automatically matches available test centers. There are rules for the ranking of Subject 1 appointments. For first-time applicants, the sorting time is based on the date when the user initially applied for the motor vehicle driver's license. For non-first-time applicants, the sorting time is based on the date of the last exam. If a user cancels a successful appointment due to personal reasons, the cancellation time becomes the sorting time. If both the second and third conditions apply, the most recent time is used as the sorting time.
