The failure to schedule the Subject 4 exam can be attributed to two main reasons: 1. Excessive number of applicants: When there are too many applicants at the time, and the priority of the scheduler is not as high as others, they will naturally be pushed out. 2. System issues: Sometimes, the system may be under too much pressure, leading to some students being unable to schedule the exam. In such cases, one can only wait for the system to be fixed. Below is relevant information about Subject 4: 1. Main exam content: Safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods in situations like tire blowouts, and knowledge on handling traffic accidents. 2. Retake instructions: If Subject 4 is not passed, there is no need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own, and no retake fee is required. There are no scheduling restrictions for the safe and civilized driving theory exam, but the validity period of the driving skill test permit is three years. If the applicant fails to complete the exam within the validity period, the results of the already passed subjects will be invalidated.

I encountered several failures when trying to book the Subject 4 test before, and there are quite a few reasons for that. The main issue could be the high traffic volume on the platform causing system lag, especially during peak hours like weekends or the end of the month. With so many people nationwide trying to secure spots at the same time, the servers can't handle it. Another possibility is that your Subject 3 test results haven’t been fully uploaded or synchronized to the system yet—you might need to wait a few business days after passing Subject 3 before booking Subject 4. Also, double-check your personal details for accuracy; mistakes like entering the wrong ID number or having spaces in your name could lead to failure. Some regions also have priority rules for bookings, where first-time applicants get precedence over retakers, depending on local traffic management policies. Lastly, there’s the payment step—if you don’t pay the exam fee on time, the system will automatically cancel your booking. My advice is to avoid peak times and try multiple times. If all else fails, it’s best to visit the DMV directly to clarify the specific reason.

I've experienced the frustration of failing to book the subject 4 test, and there are several possible reasons. First, operational issues like selecting the wrong test center or entering incorrect dates during booking can lead to no available slots being matched. Second, system restrictions may apply—some regions require completing a specified number of hours in safe driving training before you can register, and you might not have logged enough time. Additionally, network issues play a big role; unstable mobile signals during operation can cause submission failures, so trying a WiFi connection is recommended. Another factor is delayed data synchronization, such as passing subject 3 but the information not being promptly updated in the booking system. Some students also report that the booking channel may temporarily close during system upgrades or maintenance. If you keep encountering failures, it's best to contact your driving school—they're usually familiar with local regulations and can help identify exactly where the issue lies.

Is Audi Original Glass Better or Coated Glass Better?

Choosing coated glass is better. Coated glass offers many color options for the coating, and since the glass coating is applied to the 2nd and 3rd surfaces of the insulated glass, it ensures excellent durability of the coating. Additionally, selecting low-e coated glass can effectively prevent UV damage and more. Introduction to Coated Glass: Coated glass (Coated glass) is also known as reflective glass. Coated glass involves applying one or more layers of metal, alloy, or metal compound films on the glass surface to alter its optical properties and meet specific requirements. Depending on the product's characteristics, coated glass can be categorized into the following types: heat-reflective glass, low-emissivity glass (Low-E), conductive film glass, etc. Production Methods of Coated Glass: There are many production methods for coated glass, mainly including vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel methods. Magnetron sputtering coated glass utilizes magnetron sputtering technology to design and manufacture complex multi-layer film systems, allowing for a variety of colors on white glass substrates. The film layers exhibit good corrosion resistance and wear resistance, making it one of the most widely produced and used products currently.

What is the fuel consumption of the new Bora?

According to the test by the Ministry of Industry and Information Technology, the comprehensive fuel consumption of the new Bora 1.6L is around 6.8 to 7.2, while the 1.4T model is around 6.6. Introduction to fuel consumption: Fuel consumption (Constant-Speed Fuel Economy): Constant-speed fuel consumption refers to the fuel economy indicator when a car is driving at a constant speed on a good road surface. Since constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. Comprehensive fuel consumption: Comprehensive fuel consumption is tested under different conditions such as urban roads, highways, and varying loads. It is only a reference, and the actual fuel consumption may be higher or lower than this number. For example, driving daily in busy city areas, frequently braking and accelerating, can lead to higher fuel consumption, even reaching 10 liters per 100 kilometers, which is quite normal.

Which one is the low beam headlight on the Baojun 560?

The low beam headlight on the Baojun 560 is controlled by a lever on the left side of the steering wheel. Above the turn signal indicator, there is a symbol for the low beam headlight. Twist it twice to turn on the low beam. Introduction to low beam headlights: Low beam headlights are designed for close-range illumination. Their design requirements include a wide coverage angle (160 degrees) and a short illumination distance, with non-adjustable focus. Illumination range of low beam headlights: The low beam headlights illuminate approximately 30-40 meters ahead. According to experiments, when driving at 55 km/h at night, the braking distance after noticing an obstacle is exactly 30 meters. This means that if you spot an obstacle within the low beam's range and brake immediately, there will be no gap between the car and the obstacle. Of course, this is under ideal conditions with good vehicle and road conditions and a quick driver reaction. If the speed is higher, or if the vehicle or road conditions are poor, or the driver is fatigued with slower reactions, the outcome can be imagined. Therefore, it is essential to control your speed when driving at night. On flat, wide, and well-lit roads, you can use high beams and drive slightly faster. However, when encountering oncoming traffic, uneven roads, turns, bridges, narrow roads, or intersections, you should slow down, generally keeping the speed below 40 km/h.

What is the chassis code of the new Fit?

2021 Fit is the fourth generation Fit, and the chassis code of this model is GR9. The chassis code is commonly known as the frame number, similar to a person's ID number. The frame number is the ID number of that car. Normal frame number locations: Except for trailers and motorcycles, on the door hinge pillar, door lock pillar, or one of the pillars connected to the door lock pillar, near the driver's seat; fixed on the left side of the dashboard; fixed on the inner side of the door, near the driver's seat. It should be in a place where it can be easily read without moving any parts of the vehicle except for the outer door. The VIN code of most domestic cars can be found on the left side of the dashboard or below the windshield. Importance of the frame number: The frame number is like a person's fingerprint. If the steel plate with the frame number is damaged, the owner must not cut the steel plate with the frame number by themselves. The damaged condition of the vehicle must be preserved, and the car should be driven directly to the vehicle management department for certification to prove that the steel plate with the frame number is indeed damaged. Then, the vehicle management department will handle the situation according to the actual circumstances.

What is the fuel consumption per 100 kilometers for the Audi A7?

Audi A7 has an average fuel consumption of 14.45 liters per 100 kilometers. Introduction to fuel consumption: Constant-Speed Fuel Economy refers to the fuel efficiency indicator when a car is driving at a constant speed on a good road surface. Since constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. For example, France and Germany use the constant-speed fuel consumption at 90Km/h and 120Km/h as the main evaluation indicators for fuel economy. China also adopts this indicator. Fuel consumption testing: Special personnel select experimental roads, use a specially marked fuel tank to run a 100-kilometer round trip (acceleration fuel consumption can be calculated, but coasting is not allowed), and then divide by two to calculate the actual constant-speed fuel consumption per 100 kilometers.

How often should the automatic transmission fluid be changed in a new Santana?

The automatic transmission fluid and filter in the new Santana should be replaced every 60,000 kilometers, or every two years or 50,000 kilometers, whichever comes first. Transmission fluid change interval calculation: The replacement cycle for transmission fluid is calculated the same way as the vehicle's maintenance cycle, based on either mileage or time in use. If the vehicle's manual clearly specifies both indicators, follow whichever comes first. If the manual doesn't provide such indicators or doesn't clearly mark the fluid change interval, replace it every 50,000 to 80,000 kilometers. Transmission fluid change methods: Circulating machine fluid change method: This method can completely clean out the old transmission fluid. However, it's relatively expensive and suitable for vehicles less than 5 years old.
