Why is the Subject 2 Test Appointment Still Under Review?

If the Subject 2 test remains under review, it indicates the student's appointment was unsuccessful. In some regions with high applicant volumes for Subject 2 tests, the review process typically yields results within 5 working days. If no outcome is received, it means the applicant's ranking has been eliminated. In such cases, students may consult their driving school or resubmit the appointment application. Below is additional relevant information: Subject 2: 1. Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It refers to the field driving skills examination, with mandatory test items for C1/C2 license including reverse parking, parallel parking, hill start, right-angle turn, and S-curve driving (some regions may include a 6th item: highway toll card collection). 2. According to Article 36 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses': Vehicle management offices shall arrange examinations based on the scheduled test site and time. After passing Subject 1, applicants may schedule Subject 2 or Subject 3 (road driving skills test). In eligible regions, applicants may simultaneously schedule Subjects 2 and 3, allowing consecutive testing upon successful appointment. After passing both Subjects 2 and 3, applicants may participate in the Subject 3 safety and civilized driving knowledge test on the same day.

What Causes Engine Vibration When Turning on the Air Conditioning?

The reason the engine vibrates when turning on the air conditioning is: the throttle valve is dirty and should be cleaned promptly. Below are some precautions regarding using the car's air conditioning: 1. Placement and Replacement: Avoid placing items near the air conditioning intake to prevent blockage, which could hinder airflow in the system. The air purifier in the air conditioning system should be replaced regularly. Replace the deodorizing filter approximately every 3 months or every 5,000 kilometers driven. 2. Monitor Coolant Temperature: The air conditioning system should be used when the engine coolant temperature is normal. If the engine is under heavy load and causes the coolant temperature to rise excessively, stop using the air conditioning and only resume usage once the coolant temperature returns to normal.

What Causes Brake Shaking at High Speeds in Cars?

Here are the reasons for brake shaking when driving at high speeds: 1. Uneven brake disc surface: The brake disc surface is uneven, with excessive radial runout. During braking, the brake pads contact the disc unevenly, resulting in varying braking force and causing vehicle vibration, which is usually noticeable when lightly applying the brakes. 2. Significant wheel alignment deviation: Large deviations in wheel alignment data, especially incorrect front wheel alignment angles or excessive toe-in. This makes the vehicle difficult to control during acceleration, with generally minor shaking but an overall uncomfortable driving experience. 3. Incorrect tire pressure: Either too high or too low. Excessive tire pressure causes more severe vibration at higher speeds, while insufficient pressure leads to a floating sensation and pulling to one side.

What are the hazards of leaving a car running for a whole day without turning it off?

Here are the hazards of leaving a car running for a whole day without turning it off: 1. Carbon buildup: If the car remains idling for a long time, the engine will take longer to reach its normal operating temperature. The improper air-fuel mixture ratio in the engine leads to incomplete combustion, resulting in carbon buildup. Normally, cars will have some carbon buildup, which doesn't significantly affect the vehicle. However, excessive carbon buildup can cause the driver to feel a decrease in the car's power. 2. Increased fuel consumption: Idling causes carbon buildup, and excessive carbon buildup can further lead to increased fuel consumption. Besides the impact of carbon buildup, since the engine runs all night, it will consume fuel from the tank. If there isn't much fuel left in the tank, after a night of consumption, the car might even experience malfunctions. 3. Engine damage: Running the engine all night can cause significant damage. The engine contains many components that experience wear during normal driving. Continuous operation will undoubtedly worsen this wear and affect the oil pump, pistons, and even the connecting rods in the car.

How Often Should Wiper Blades Be Replaced on a New Car?

Car wiper blades can be replaced every 1-2 years. Here are some precautions for using car wiper blades: 1. Dirty wiper blades will shorten their lifespan: If the wiper blades themselves are not clean, gaps may appear during use, potentially wearing away the lubricating graphite. This affects performance, increases resistance during operation, and over time, shortens the lifespan of the wiper rubber. 2. Dry wiping damages the windshield: When the windshield is dry and the wipers are used without water, it can harm both the wiper blades and the windshield. Scratches on the windshield can impair visibility while driving, compromising road safety.

Private vehicles are not allowed to tow broken-down vehicles on highways; only rescue vehicles or wreckers can perform towing operations. Below is relevant information about highway towing: 1. When a motor vehicle breaks down on the highway: The procedures stipulated in Article 52 of this law shall be followed. However, warning signs must be placed at least 150 meters behind the disabled vehicle in the direction of approaching traffic. All passengers should quickly move to the right shoulder or emergency lane and immediately call the police. If a motor vehicle becomes disabled or is involved in an accident on the highway and cannot be driven normally, it must be towed by a rescue vehicle or wrecker. No organization or individual may intercept vehicles for inspection on highways, except for police officers performing official duties in accordance with the law. 2. The towing of trailers by motor vehicles must comply with the following regulations: Trucks, semi-trailer tractors, and tractors are only permitted to tow one trailer. The trailer's lighting signals, brakes, connections, and safety devices must meet national standards. Passenger cars are only allowed to tow recreational trailers or trailers with a total mass under 700 kg. Trailers must not carry passengers.
