How to Immediately Know If You Have Committed a Traffic Violation?

What does front-engine four-wheel drive mean?

Front-engine four-wheel drive (4WD) refers to a vehicle configuration where the engine is positioned at the front of the vehicle, and power is delivered to all four wheels. Since all four wheels receive power, this design offers superior handling performance compared to vehicles that rely solely on front-wheel or rear-wheel drive. Additional details: 1. This layout is commonly used in rally racing and off-road vehicles due to its stability, particularly on challenging terrains such as hills, beaches, mud, and deserts. 2. It provides excellent traction not only on rough surfaces but also on wet or winter roads. For high-powered vehicles, it also offers advantages on dry, well-paved roads.

Where to Inflate Underinflated Tires?

Here are the solutions for underinflated tires: You can go to an auto repair shop or a 4S dealership to have your tires inflated. Alternatively, you can use a bicycle pump to inflate them. The best option is to purchase a portable electric car air pump (make sure it comes with a tire pressure monitoring device) and keep it in your car for convenient tire inflation anytime. Additional information: 1. The most severe consequence of underinflation is a tire blowout. Similarly, overinflation can also lead to blowouts. However, underinflation is often hard to detect unless deliberately checked. Driving for extended periods with low tire pressure can cause significant damage to the tires and, in severe cases, endanger the safety of the driver and passengers. 2. Underinflation causes considerable harm. Firstly, it increases the tire's self-friction coefficient during movement. The flattened contact patch of the tire creates an abnormal motion compared to the unaffected side, causing the tire to operate out of its normal circular shape. This leads to increased tire temperature.

Is it necessary to replace brake pads at a 4S shop?

Brake pads do not necessarily need to be replaced at a 4S shop; they can also be replaced at a repair shop or even by yourself. The cost of brake pads varies depending on the location, vehicle model, and the material of the brake pads. Outside of 4S shops, the quality of brake pads may differ, and it cannot be guaranteed whether they are original. Below is some relevant information: 1. Whether the brake discs need to be replaced can be determined by yourself. Each person's driving habits have a certain impact on the replacement of brake pads. If they are replaced based solely on a uniform mileage standard, it may lead to waste or excessive wear, posing potential hazards. Generally, new brake pads are about 1.5 cm thick. If they wear down to one-third of their original thickness, meaning less than 5 mm, it is recommended to replace them promptly. 2. A good and efficient braking system must provide stable, sufficient, and controllable braking force. The working principle of braking mainly relies on friction, involving the friction between the brake pads and the brake discs (or drums) as well as the friction between the tires and the ground. When replacing brake pads, it is advisable to use original spare parts provided by the manufacturer. Only in this way can the braking effect between the brake pads and the brake discs be optimal, with minimal wear. You should choose brake pads produced by reputable manufacturers, which have a license number, specified friction coefficient, and comply with execution standards. The packaging should include a certificate of conformity, production batch number, and production date.

Can You Slam the Accelerator with a CVT?

CVT transmissions should not be subjected to sudden, aggressive acceleration. For automatic transmission vehicles, theoretically, the deeper you press the accelerator, the faster the speed increases. However, CVT transmissions do not have a gear structure; instead, they use a metal chain and pulleys for power transmission. When subjected to excessive load, the chain can slip, causing the engine to rev without proper power transfer, which may damage the engine. A CVT, or continuously variable transmission, is characterized by its lightweight, compact size, and fewer components. Prolonged aggressive driving behaviors such as driving at excessively high speeds in low gear, driving at low speeds in high gear, sudden acceleration, and hard braking fall under the category of abusive driving for CVT transmissions. Extended periods of such driving can lead to issues like increased oil consumption, and in severe cases, may cause brake pad overheating, reduced braking efficiency, cylinder scoring, or even engine seizure.

How Many Days to Receive Notification for Highway Reversing Violation?

Highway reversing violations are typically notified within three days through SMS, postal mail, or email to the vehicle owner. According to relevant regulations, reversing or driving in the wrong direction on a highway not only results in a fine but also deducts 12 points from the driver's license. The offending driver must participate in road safety training and exams organized by traffic authorities. Only after passing the exam can the driver regain their driving privileges. If the exam is failed, the driver must continue studying and retaking the exam until they pass. If a driver misjudges the direction and misses an intended exit or junction, they must not reverse. Instead, they should continue driving to the next exit, leave the highway, and then plan a new route to return to the desired exit.

Can a Damaged Sidewall Be Repaired?

The sidewall is the weakest part of a tire. Generally, once a car tire's sidewall is damaged, it cannot be repaired, which is different from damage to the tire tread. Secondly, whether to continue using the tire or replace it depends on the specific situation. The judgment methods are as follows: 1. During parallel parking, improper observation or operation may cause the tire sidewall to come into contact with the curb, resulting in damage. Such minor scrapes usually have little impact on the tire sidewall. If there is no significant surface damage, you can continue using the tire, but you must pay extra attention to its condition. Replace it immediately if air leakage occurs. 2. If you encounter potholes while driving at high speed and cannot avoid them in time, the tire sidewall may suffer significant pressure and tear. In this case, replacement is strongly recommended. 3. When low-profile tires are impacted, the sidewall may bulge. A bulging tire poses a serious safety hazard, as it can blow out at any time and compromise driving safety. Therefore, it must be replaced.
