How long does it take to get the result of Subject 4 application?

Generally, a text message reply will be given within 7 days. Confirming registration status: There is a certain delay in the driving test system, and the system will provide a reply at the latest 2-5 days before the scheduled exam date. If there is no reply for a long time, it is best to call the local vehicle management office to clarify whether the registration was successful, to avoid missing the exam or making a wasted trip on the day thinking the appointment was successful. Driving test appointment ranking rules: First-time appointment: The sorting time is based on the date when the user initially applied for a motor vehicle driver's license. Non-first-time appointment: The sorting time is based on the date of the last exam. Self-cancellation: If a user who successfully scheduled an exam cancels the appointment due to personal reasons, the sorting time is based on the cancellation date. Simultaneous compliance: If both the second and third conditions are met, the most recent time is used as the sorting time.

What brand of tires does the Trumpchi GA6 use?

Trumpchi GA6 uses Michelin brand tires. Michelin Group is a global leader in tire technology, established a century ago in Clermont-Ferrand, France. In addition to tires, Michelin Group also produces rims, steel wires, mobility assistance systems, travel services, maps and travel guides, with its map and guide publishing arm being a leader in the field. More details are as follows: 1. Michelin is the world's number one tire brand and the inventor of radial tires. In fact, Michelin is a manufacturer with relatively balanced technology, slightly emphasizing comfort and quietness. Although Michelin tires are more prone to wear due to their softer sidewalls, the Michelin EverGrip technology ensures that the tires maintain a certain level of grip even after the tread pattern wears down. Additionally, Michelin tires are generally priced higher, making them suitable for owners who prioritize comfort and quietness and have no budget constraints. 2. Tires are consumables and need to be replaced every few tens of thousands of kilometers. You can refer to the tire wear indicators in the main drainage grooves of the tire. When the tire tread wears down to the level of the wear indicators, it means the tires need to be replaced. When tires reach their wear limit, the wet grip area is significantly reduced, severely compromising safety in wet conditions. Therefore, never wait until the tires are completely bald before replacing them.

What are the effects of parking on uneven roads for a long time?

Parking on uneven roads for a long time has the following effects on the vehicle: 1. The tires and suspension on the lower side of the vehicle will bear greater force, affecting the chassis and suspension. 2. The higher side of the suspension system will experience uneven force distribution, which may affect the shock absorption performance over time. 3. The chassis may also deform due to prolonged uneven force distribution. Here is some extended information about the effects of long-term parking on uneven roads: 1. Tires, being the part of the vehicle in direct contact with the ground, may deform due to prolonged parking on uneven roads, leading to uneven force distribution. This can cause steering wheel deviation or vibrations while driving, significantly affecting driving comfort and stability. 2. Improper parking can result in doors not closing tightly or poor sealing. Parking on uneven surfaces for extended periods can cause the vehicle to experience unbalanced forces and excessive wheel height differences, leading to frame deformation and twisting. Therefore, it is advisable to choose flat surfaces for parking whenever possible.

What are the methods to avoid crossing the line when turning in an S-curve during Subject 2?

Here are the methods to avoid crossing the line when turning in an S-curve during Subject 2: 1. When entering the curve, position the front of the car in the middle. When the left corner of the car touches the right line, turn the steering wheel left by one and a half turns (45 degrees) and maintain the course. When the left corner of the car touches the left line of the second curve, straighten the steering wheel. When the right corner of the car touches the left line of the second curve, turn the steering wheel right by one and a half turns (45 degrees). Once the car is straight, straighten the steering wheel and slowly exit the S-curve. 2. When navigating the S-curve, it is crucial to control the speed properly. Press the clutch gently to slow down, which increases reaction time. Even if the direction is slightly off, it can be adjusted in time to avoid crossing the line. 3. There are two entry directions: left entry and right entry. For a left entry, keep the vehicle as close to the right line as possible before turning the steering wheel left. For a right entry, do the opposite—keep the vehicle as close to the left line as possible before turning the steering wheel right. This accounts for the inner wheel difference, preventing the rear wheels from crossing the line during the turn.

How to Replace Transmission Oil with a Flushing Machine?

There are currently two common methods for replacing transmission oil with a flushing machine: gravity oil change and flushing machine oil change. A flushing machine is a device that utilizes pressure to dynamically replace automatic transmission fluid. The principle involves simultaneously extracting the old oil and injecting new oil, using pressure to push out the old oil with the new oil. The advantages of using a flushing machine for oil change are as follows: 1. The oil change is more thorough, with an oil change rate of over 95%. 2. It is simple and labor-saving. 3. It can clean the internal sludge and metal debris of the automatic transmission, thereby appropriately extending the maintenance cycle of the transmission oil.

Can Four-Wheel Drive Vehicles Not Be Towed?

Yes, but it depends on the situation. Among the three towing methods—tow rope towing, lift towing, and flatbed towing—only flatbed towing is suitable. Tow Rope Towing: Tow rope towing refers to providing power to the towed vehicle through a tow rope. It is not recommended to tow a four-wheel drive vehicle this way because if the vehicle is not started, the steering wheel cannot be turned, and the brake booster does not work. Forcibly towing may cause the anti-theft module and transmission to lock up, damaging the car. Lift Towing: This involves using a tow truck to lift the two front wheels of the towed vehicle off the ground, relying on the rear wheels to roll for towing. In a four-wheel drive vehicle, all four wheels rotate together, coordinated by the transmission, central differential, and drive shaft. If only the rear two wheels rotate, these three major components fail to coordinate, potentially causing damage to the drivetrain, central differential, and other parts, with significant harm to full-time four-wheel drive vehicles. Flatbed Towing: This method involves lifting the vehicle or using other means to place it on a flatbed truck. In this case, the vehicle is essentially parked on the truck, with neither the front nor rear wheels rotating. As long as it is properly secured, there is minimal risk of damage to the vehicle.
