What is the speed requirement for straight-line driving?

Straight-line driving requires a speed of no less than 30km/h and no more than 40km/h, with the optimal speed controlled at 36km. The following are relevant details: 1. Steering wheel issue in straight-line driving: Straight-line driving means maintaining the vehicle's straight-line movement, not keeping the steering wheel motionless. However, there are techniques for operating the steering wheel. Generally, the right hand performs actions like acceleration and gear shifting, making it especially important for the left hand to hold and stabilize the steering wheel. Additionally, slight adjustments can be made to the steering wheel during driving, but sudden and forceful movements should be avoided. 2. Vision issue in straight-line driving: Adhere to the principle of "looking far while taking care of the near." This means looking ahead to spot situations early and react in advance, while also paying attention to the immediate surroundings and the rear of the vehicle. Since the speed in the third section of the driving test is fast, looking far ahead helps in early detection of situations and making preemptive responses. At the same time, the vehicle is more likely to maintain a straight path.

Is it serious if there is a clicking sound when shifting into P gear without the car being fully stopped?

It is not serious if there is a clicking sound when shifting into P gear without the car being fully stopped. Incorrect gear shifting operation: Downshifting requires deceleration first. Before shifting gears, the clutch pedal must be fully depressed. The gear lever should be operated gently, quickly, softly, and accurately. The clutch must be pressed all the way down, and gear shifting should be done in one smooth motion. Excessive wear of the gear lever ball socket: Excessive wear of the gear lever ball socket can cause the lower end of the gear lever to fail to push the sliding gear into place when shifting into first gear or reverse gear. This means it may slip out from above the groove of the first or reverse gear shift fork shaft guide block, preventing the first or reverse gear shift fork shaft from reaching the correct position during gear engagement. It is recommended to visit a repair facility to replace the gear lever.

Do I Need to Change to Snow Tires in Winter If It Doesn't Snow?

In winter, if it doesn't snow, you don't need to change to snow tires. Reasons are as follows: When entering winter, the all-season tires equipped by car manufacturers when the vehicle leaves the factory can handle common road conditions. The performance of all-season tires is a compromise between summer tires and winter tires. Whether to change to winter tires depends not only on personal driving conditions but also mainly on environmental factors. For example, four-wheel-drive vehicles have higher tire stability, and unless there is particularly heavy snowfall, driving only in urban areas may not require a change. However, if the winter is very cold with significant rain and snow, it is advisable to change to snow tires as a precaution. Disadvantages of Using Snow Tires in Winter: Although snow tires can prevent slipping in winter, they also have certain drawbacks. Vehicles with snow tires will experience significantly increased fuel consumption, and due to the greater friction between snow tires and the road, tire noise on ordinary roads will be very noticeable.

Why does the car make a creaking sound at low speeds but disappears after acceleration?

If the car makes abnormal noises at idle speed and the noises disappear after pressing the clutch, it indicates that the source of the noise is a transmission fault. Internal contamination of the transmission: When an automatic transmission malfunctions, in many cases, it is not due to damage to the internal valve body but rather the presence of stubborn dirt and impurities inside. Especially when dirt and impurities accumulate inside the valve body, forming blockages, it prevents effective regulation of oil pressure, leading to issues like jerking, impact, and slippage. High temperature damages the transmission: High temperatures can degrade the quality and friction characteristics of automatic transmission fluid, increasing friction and wear, which results in transmission noise. At the same time, sludge can form inside the transmission, causing jerking and impact. If the temperature exceeds 120 degrees Celsius, rubber sealing materials begin to harden, eventually leading to leaks and reduced hydraulic pressure. If the temperature rises even higher, the transmission starts to slip, and the slippage in turn causes the temperature to rise further.

How to Read a Tire Inflation Pressure Gauge?

Tire inflation pressure gauge reading method: Align and press the measuring end slot of the pressure gauge against the tire valve stem. At this point, the pointer on the tire pressure gauge will deflect, and the indicated value is the inflation pressure of the tire. Alternatively, the gauge's indicator rod may be pushed out by the air pressure, and the value displayed on the rod is the tire's inflation pressure. The greater the internal pressure, the more the pointer deflects. Tire pressure precautions: 1. For passenger car tires, the pressure is usually between 2.0 and 2.5 bar, not exceeding 3.5 bar; 2. For light truck tires, typically 6-ply tires should be between 3.0 and 3.5 bar, 8-ply tires between 4.0 and 4.5 bar, and 10-ply tires not exceeding 5.5 bar; 3. For trailer tires, the pressure usually should not exceed 4.2 bar.

What happens if tire pressure is too low in snowy winter?

Low tire pressure in snowy winter can affect driving safety, and the tire pressure should be adjusted promptly. Reference standards for adjusting tire pressure: According to the international GBT2978-2008 standard, the standard tire pressure is approximately 2.4-2.5 bar for standard tires and 2.8-2.9 bar for reinforced tires. In winter, it is advisable to slightly increase the tire pressure by about 0.2 bar based on the standard tire pressure. Always use a pressure gauge to check the pressure to avoid overinflation, which can cause tire blowouts. Effects of low tire pressure: It significantly increases friction between the tire and the ground, causing a rapid rise in tire temperature, softening the tire, and drastically reducing its strength. When driving at high speeds, this can lead to blowouts. It also increases tire deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat buildup, accelerating rubber aging, fatigue in the cord layers, and cord breakage. Additionally, it increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
