What Causes the Jerking Sensation When Shifting Gears While Driving?

Driving with a jerking sensation during gear shifts is caused by the transmission oil not being replaced in time, leading to changes in its performance. Below is relevant information about gear shifting: Gears: The tire's rotating shaft has gears for different gear positions. When the engine speed remains constant, engaging gears of different sizes (different gear positions) with the engine results in the larger gear obtaining a lower circumferential speed than the smaller gear. Torque: According to the principles of torque, in lower gears, the larger gear allows the engine to drive a larger radius with a smaller radius, providing the car with greater driving force. In higher gears, the engine drives a smaller radius, resulting in a faster circumferential speed, meaning the car moves faster but with less torque, i.e., less driving force. Therefore, shifting gears in a car essentially changes the transmission gears.

Can I replace only one license plate?

If replacement is needed, both plates must be replaced together. However, you can also choose not to replace them and simply report the plate as lost, then proceed to apply for new plates directly. When applying for replacement plates, two plates are always issued at once. The rear plate can be kept as a spare without replacement. Materials required for replacing a new license plate: (1) Application form for motor vehicle license plate replacement (the content of the application form should be filled in with a pen or signature pen and must not be altered). (2) Vehicle license plates. (3) If one plate is lost or replaced, the other plate should be surrendered and replaced; if damaged or replaced, both plates should be surrendered and replaced simultaneously. (4) Original and copy of the identity proof of the motor vehicle owner. (5) If a representative is handling the case, they must also submit their identity proof.

When to Use Hazard Lights?

The following situations require the use of hazard lights. 1. Driving in fog: Due to poor visibility in foggy conditions, it is necessary to turn on both hazard lights and fog lights to alert passing vehicles and provide illumination for yourself. 2. In case of a traffic accident: Hazard lights should be activated when a vehicle breaks down or is involved in an accident on the road to warn other vehicles for safety. On highways, failure to use lights and set up warning signs properly after a breakdown or accident will result in a 12-point penalty. 3. Towing a faulty vehicle: Both the towing vehicle and the towed vehicle should turn on hazard warning lights to indicate their abnormal status. 4. Temporary parking: When temporarily parked on the road, turn on hazard lights to alert other vehicles.

Will replacing the car film damage the rear window heating wires?

Heating wires are highly likely to be damaged, but using the correct method to replace the car film will not harm the rear window heating wires. During the replacement process, technicians use a heat gun to warm the film, ensuring it separates from the glass so the old film can be peeled off. If the heating wires are already broken, they cannot be repaired. Even a slight break in the rear window heating wires renders them ineffective, as it disrupts the heating function of the rear window glass. A break in the wires interrupts the circuit, and there is no way to fix them once they are damaged. While this does not affect the overall vehicle, it means you won't be able to clear fog from the window. If the wires break, the entire rear window glass must be replaced because the heating wires are installed during manufacturing and are very fragile. Although they are rarely used throughout the year, if they break, they should not be used or repaired—simply replace the glass.

Why Are Laser Lights Installed on Highways?

Highway roads are straight with few fixed reference points, leading to monotonous driving actions and a single line of sight for drivers. Prolonged driving under such conditions can easily cause drowsiness. This is more pronounced in summer, as the daytime heat drains physical energy. Freight drivers often undertake long-distance trips at night, making them prone to fatigue driving, which has become a key illegal activity targeted for prevention and enforcement by highway traffic authorities. Installing laser lights can alter the monotonous driving environment and mitigate visual fatigue through changes in light. After multiple rounds of concentrated discussions, highway traffic police have placed laser lights on relatively straight sections of road where fatigue driving is more likely to occur. The lasers are adjusted to ensure sufficient brightness while also providing a certain visual impact. The laser lights come in two forms: continuous and strobe, with a range of 2 kilometers.
