Is driving at 120 km/h in rainy weather when the speed limit is 80 km/h on the highway considered speeding?

What are the considerations when enrolling in a driving school?

With the increasing popularity of cars, more and more people are obtaining driver's licenses. When enrolling in a driving school, you should pay attention to the following: 1. Non-local residents must handle their residence cards properly. According to driving school regulations, those without local household registration must take the test in their hometown. Although they can learn to drive nearby, they must first process their residence cards. 2. Ensure accurate identity information. When enrolling, you must bring your ID card to confirm that your identity information matches the ID card or household registration. 3. Record multiple fingerprints during the fingerprinting process. Currently, both theory and practical training require students to sign in with fingerprints. Having multiple fingerprints prevents issues like peeling skin later on, ensuring there are additional fingerprints available for use.

What Causes the Buzzing Sound from the Chassis While Driving?

Below are the reasons for the buzzing sound from the chassis while driving: 1. The wheel bearing has been contaminated with impurities or water, the bearing is damaged, there is insufficient lubrication, or abnormal wear of the steel ring and ball bearings; if there is a problem, the source of the abnormal noise must be identified, and generally, this type of noise can be resolved by replacing the bearing. 2. Loose exhaust pipe hangers; aging, cracking, or broken rubber hangers, fractured hanger brackets, rusted or damaged fastening bolts, and other reasons can cause the exhaust pipe to be loosely connected, resulting in abnormal noise, including buzzing sounds. 3. Tire imbalance: affects the stability of the vehicle while driving; 4. Deformed tie rods.

Do Cars Need to Warm Up Before Driving?

Car engines do require warming up. Here are the relevant details about warming up your car: 1. Reason: After starting the car, let it idle for about a minute. When a car remains stationary for an extended period, the engine oil gradually settles to the bottom of the engine. As a result, there is no oil lubrication between the various components inside the engine. 2. Warming up technique: After starting the car, you'll notice the engine speed is around 1200 RPM. After about a minute of idling, the speed will drop to approximately 800 RPM, indicating the warm-up is complete. How long should you warm up your car before driving? The car can be driven once this signal appears. Otherwise, it may lead to increased carbon buildup in the engine, which can be more damaging than not warming up the car at all.

Can cars without ETC use highways?

It is possible to use highways without ETC. According to Article 19 of the "Notice on Vigorously Promoting the Development and Application of ETC on Expressways" issued by the State Council, vehicles without ETC by 2020 cannot enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual channels. Additionally, newly installed ETC devices cannot be used on highways immediately; they must be activated before normal use. During free holiday periods, highways can still be used. For users who have already installed ETC, passing through ETC lanes will not incur charges. ETC Deduction Principles: There will be one or more ETC lanes on highways. Through microwave-specific short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, computer networking technology is used to conduct background settlement with banks. This achieves the goal of vehicles paying tolls without stopping at highway toll stations, all based on the principle of passing first and deducting fees later. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear: Saves costs, decreases the frequency of vehicle starts and brakes, and reduces wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times or more, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also set a clear target in the main indicators of the "13th Five-Year" comprehensive transportation development: "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC adoption rate for passenger vehicles, future efforts will include promoting ETC use for trucks and exploring the deep integration of the ETC system with smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide car owners with comprehensive travel services, meaning more application scenarios will support ETC applications.

Are Antifreeze and Coolant the Same Thing?

Engine coolant and antifreeze are not the same thing. Coolant is a liquid that can lower the temperature of the engine. It circulates within the engine cooling system, carrying away excess heat generated during engine operation, allowing the engine to operate at normal working temperatures and providing a cooling effect. Antifreeze, whose full name is antifreeze coolant, is a coolant with special additives that provide antifreeze properties. Antifreeze not only prevents freezing but also offers cooling, anti-corrosion, and anti-scaling effects. Below is a related introduction: Antifreeze can prevent the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or the engine cylinder block or cylinder head to freeze and damage. However, antifreeze is not just for winter use; it is used throughout the year. In regular car maintenance, engine antifreeze should be replaced every year, with special vehicles requiring more frequent antifreeze changes. Coolant, on the other hand, can only be used in summer. In winter, when temperatures are low, coolant lacks antifreeze properties and is prone to freezing. Coolant is not equivalent to antifreeze, but antifreeze can be equivalent to coolant.

Can Scratched Wheel Rims Be Repaired?

Scratched wheel rims can be repaired. Here is relevant information about wheel rims: 1. Wheel rim scratches are generally categorized into surface scratches and rim edge scratches. After being scratched and losing paint, the wheel rim loses its protective layer. Prolonged exposure in this condition can lead to oxidation and corrosion of the rim surface. 2. Once the aluminum alloy material of the wheel rim is damaged, the rim is rendered unusable. Particularly, corrosion resulting from unrepaired edge scratches can cause the tire to not fit tightly with the rim, leading to slow air leakage and compromising safe usage. Daily maintenance of car wheel rims includes: (1) When the car has been driven for an extended period and the wheel rims are hot, avoid washing them with cold water. Instead, wait for the rims to cool naturally before cleaning. Washing hot rims can cause chemical reactions on the surface, leading to loss of gloss and affecting the overall appearance of the car. (2) Never use an iron brush when cleaning wheel rims to prevent surface damage. Opt for a soft-bristled brush or a specialized wheel rim cleaning brush.
