How Long After Passing Subject 1 Can You Schedule Subject 2?

You can schedule the Subject 2 driving test online 10 days after passing Subject 1. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the registration requirement for Subject 2 is completing 26 study hours, including 2 hours of theoretical knowledge, 3 hours of simulated driving, and 21 hours of practical training. For a C1 driver's license, you can schedule the Subject 2 test online 10 days after passing Subject 1. Each Subject 2 test appointment includes two exam attempts. If you fail the first attempt, you can retake it once for free. If you do not take the retest or fail the retest, the exam session ends, and you can reschedule the Subject 2 test after 10 days. Within the validity period of the driver's license learning period, you can schedule the Subject 2 test no more than 5 times. If you fail the fifth attempt, all previously passed subjects will be invalidated. To continue learning for the driver's license, you must restart the process from Subject 1. Subject 2 test content includes: completing specified driving tasks within a designated area; demonstrating mastery of vehicle driving skills; and assessing the ability to judge the vehicle's spatial position. Subject 2, also known as the "small road test," consists of five required tasks: reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves. Subject 2 test tips: After getting into the car, adjust the seat and mirrors to the proper position and ensure the seatbelt is fastened. For parallel parking, find the correct angle quickly, turn the steering wheel rapidly, and coordinate with the vehicle's speed. On the slope, remember to engage the handbrake, signal left when starting, and release the handbrake. Control the clutch while gently pressing the accelerator to avoid stalling or rolling back. For right-angle turns, react quickly once the turning point is identified and coordinate with the vehicle's speed to prevent deviation. For curve driving (S-curve), reduce speed and proceed slowly. Those with good driving sense may pass smoothly in one go. When reversing into a parking space, control the speed, identify reference points, and make minor adjustments if deviations are noticed in the mirrors. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 covers traffic laws, regulations, and related knowledge; Subject 2 tests field driving skills; and Subject 3 consists of two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, commonly referred to as Subject 4, though this term is not officially recognized in regulations (e.g., the Ministry of Public Security's Order No. 123).

Will using 92 octane fuel in a car that requires 95 octane have any impact?

Using 92 octane fuel in a car that requires 95 octane will have an impact. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles designed for lower octane fuel, using higher octane fuel will not cause damage, but the increase in octane rating will alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, with the practical effect being poorer performance. For vehicles designed for higher octane fuel, using lower octane fuel can cause engine knocking. Because the octane rating is too low, the fuel's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will develop during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring. Besides checking the appropriate gasoline grade in the car's manual, you can also find it on the fuel tank cap. Generally, the gasoline grade can also be determined by the engine's compression ratio. Cars with a compression ratio between 8.6-9.9 should use 92 octane fuel, while those between 10.0-11.5 should use 95 octane. Higher compression ratios may require 98 octane fuel. However, with modern technologies, the compression ratio alone cannot determine the required gasoline grade, as high compression ratios can be tuned to use lower octane fuel. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, higher octane fuel has a higher octane rating and better anti-knock properties. 92 octane fuel contains 92% isooctane and 8% n-heptane, while 95 octane fuel contains 95% isooctane and 5% n-heptane.

What is the Concept of Motor Vehicles?

Motor vehicles refer to wheeled vehicles powered or towed by power devices that are used for transporting people or goods on roads, as well as for specialized engineering operations. In practice, the most common motor vehicles include cars and trucks. The state implements a registration system for motor vehicles. Only after being registered with the traffic management department of the public security authority can a motor vehicle be driven on roads. For motor vehicles that have not yet been registered but require temporary road use, a temporary pass must be obtained. Non-motor vehicles refer to means of transportation powered by human or animal force on roads, as well as vehicles such as disabled motorized wheelchairs and electric bicycles that, although equipped with power devices, have a designed maximum speed, unladen mass, and dimensions that comply with relevant national standards. Therefore, electric bicycles that meet national standards are not classified as motor vehicles. Vehicle classification is a fundamental aspect of various vehicle standard systems. Different standards have different vehicle classification methods, which may cross-reference each other while also having their own focuses and distinctions. Only by correctly understanding and grasping the basic concepts and applicable scopes of different classification methods, and clarifying the connotation and extension of specific definitions, can relevant standard clauses be accurately applied in motor vehicle inspection practices to precisely determine vehicle types and correctly issue inspection conclusions.

Will an automatic transmission car roll back on a slope?

If an automatic transmission car is in neutral gear, it will roll forward or backward as long as the handbrake is not engaged or the brake pedal is not pressed. Reasons for rolling back on a slope: 1. Not pressing the brake, inertia: The driver does not press the brake or engage the handbrake, causing the vehicle to roll back due to inertia. 2. Insufficient power: In neutral gear, the power is insufficient, or the vehicle's idle power is limited, and the slope is steep. When in D gear, the vehicle's power is insufficient, leading to rolling back. 3. Delayed power response: Some automatic transmission models experience a delay in power delivery when releasing the brake and pressing the accelerator, causing the vehicle to roll back.

What Preparations Are Needed After Buying a New Car?

After purchasing a new car, you can make the following preparations: 1. Vehicle Inspection: Before inspection, check the car body for scratches. It is recommended to wash the car thoroughly. You can also have a maintenance check at the 4S store before the inspection (for new cars, a detailed inspection can be done at the time of pickup, and any issues should be addressed by the staff or even consider returning the car). 2. Eliminate Interior Odors: New cars often have strong odors, so it's essential to remove these smells immediately after purchase. These odors contain a significant amount of formaldehyde, making it crucial to place charcoal bags inside the car to absorb the formaldehyde. 3. Install a Dash Cam: A dash cam can record most incidents that occur in front of the car, which is very useful for handling emergencies. For beginners who lack experience in driving skills and dealing with unexpected events, installing a dash cam before hitting the road is vital to protect their legal rights. 4. Enhance Anti-Theft Measures: After buying a new car, it's important to prioritize anti-theft measures. Purchasing a steering wheel lock is highly recommended. There are various types of steering wheel locks available, such as double-bar baseball locks, T-shaped locks, and telescopic locks.

Where to Collect the Annual Inspection Sticker for a Newly Purchased Car?

If the vehicle qualifies for the six-year exemption from inspection, you don't need to drive the car there. Simply bring the vehicle registration certificate, the ID card of the person named on the registration, and a copy of the valid compulsory insurance policy. It's best to handle this within three months before the policy expires. If there's less than one month remaining, you can still proceed, but don't wait until it's expired. Here is additional information: According to relevant regulations, starting from October 2015, an on-site inspection is not required. However, the owner still needs to provide proof of compulsory traffic accident liability insurance, proof of payment or exemption of vehicle and vessel tax, and after settling any traffic violations or accidents, they can directly apply to the traffic management department for the inspection sticker.
