What does incorrect driving posture in Subject 3 mean?

Incorrect driving posture in Subject 3 includes the following points: 1. Wrong gear shifting: The Subject 3 test clearly stipulates that looking down at the gear lever is prohibited when shifting gears. As many beginners are unfamiliar with the gear positions, they may engage the wrong gear when shifting. 2. Shifting too quickly: If the gear lever stays in neutral for too short a time during shifting, the neutral sensor may not detect it before engaging another gear, and the computer will also judge it as wrong gear shifting, resulting in immediate point deduction. 3. Staying in neutral for too long: Although staying in neutral is required when shifting gears, it should not be prolonged. Especially during straight-line driving, when shifting gears at high speed, the distance of coasting in neutral can easily exceed 100 meters. 4. Not stepping on the accelerator promptly when starting: When starting with half-clutch, first release half of the clutch, wait until the car body starts to shake, then release the handbrake. When the handbrake is fully released, immediately step lightly on the accelerator to give gas. If the action of stepping on the accelerator is not timely at this moment, the system will judge it as "incorrect driving posture".

Does Driving Resistance Increase or Decrease in Rainy Weather?

Driving resistance increases in rainy weather. Here are some rainy day driving tips: 1. Brake in advance: The braking distance on muddy or wet roads can be up to 3 times longer than on dry roads. Brakes are less effective in the rain, so slow down and brake earlier. 2. Do not reduce tire pressure: Some people lower their tire pressure during the rainy season, thinking it will increase the contact area between the tire and the ground for better traction. However, this has the opposite effect. Increasing the contact area reduces the pressure per unit area of the tire on the ground, weakening the force that pushes away the water film between the tire and the road, making the tire more prone to slipping. Therefore, lowering tire pressure does not improve traction—in fact, increasing tire pressure helps prevent slipping.

What is the difference between headlights and high beams?

The main differences between headlights and high beams are as follows: 1. Conceptual aspect: Headlights refer to front lights, including high beams, low beams, and turn signals. High beams specifically refer to the high beam function. 2. Illumination distance: Headlights have varying illumination distances. Among them, low beams have a shorter illumination distance, while high beams have a longer illumination distance. High beams provide higher and farther illumination. High beams focus their light to emit parallel beams, which are more concentrated and brighter, allowing illumination of objects that are farther and higher. Below is additional information: Drivers should immediately switch from high beams to low beams under the following circumstances: 1. When there is an oncoming vehicle; 2. When the distance to the vehicle ahead in the same direction is relatively close; 3. When the road is already sufficiently illuminated; 4. When entering busy streets with heavy traffic.

Can You Wear a Hat While Driving?

You can wear a hat while driving, as there are no regulations in China's road traffic laws that prohibit wearing a hat while driving. Here is some additional information: 1. Do not make phone calls while driving: If a driver is found making or receiving phone calls, watching TV, or engaging in any other behavior that hinders safe driving while operating a motor vehicle, they will be fined between 20 and 200 yuan and receive a 2-point penalty. If you must answer a call, pull over to the side of the road and resume driving only after handling the matter. 2. Do not wear high heels, slippers, or drive barefoot: According to the Road Traffic Safety Law, drivers are not allowed to wear high heels exceeding 4 cm while operating a motor vehicle. Violators will receive a warning and a fine of 50 yuan. If an accident occurs, the fine increases to 200 yuan. Drivers who fail to maintain a safe distance or wear high heels while driving will bear full responsibility for the accident. 3. Do not wear gloves while driving: Wearing gloves can cause the steering wheel to slip, especially during sharp turns, increasing the risk of understeering and accidents. 4. Remove accessories and hanging ornaments while driving: In the event of a sudden emergency, the body may lunge forward due to inertia, and the seatbelt can exert significant pressure. Wearing hanging ornaments at this time may lead to serious injuries such as sternum fractures.

Why is there a clicking noise when the car window is rolled up to the top?

Here are the possible reasons for the clicking noise when the car window is rolled up to the top: 1. It may be caused by aging of the window seal strip. After the seal strip ages, the friction increases, resulting in the noise. In this case, the problem tends to be more noticeable in summer because the aged seal strip expands more severely after exposure to the sun, increasing friction and making the noise more pronounced. 2. It could be due to dirt in the gap between the glass and the seal strip. Particles in the dust rubbing against the glass can also produce noise. 3. The glass guide rail might be dirty. 4. The issue could be caused by a malfunctioning window lift motor.

How to Determine if a Car Has Just Been Scratched?

Here is an introduction on how to determine if a car has just been scratched: 1. Color: Fresh scratches are usually clean and bright, with a color closer to the car's original paint. Older scratches may appear darkened and have accumulated dust. 2. Texture: Feel the scratch with your hand. If it feels noticeably uneven with obvious burrs, it is likely a fresh scratch. If the scratch feels smoother, it is probably an older one. Additional Information: 1. Shallow Scratches: If the scratch is shallow, you can try polishing to remove minor surface scratches. Minor scratches can also be repaired by applying toothpaste. 2. Deep Scratches: These can only be repaired by repainting. You can purchase specialized touch-up paint kits online for repair, but DIY attempts may have issues, so it's best to visit a 4S shop for repainting.
