Why Honk More When Driving in Foggy Weather?

Honking more when driving in foggy weather is to attract the attention of others and avoid potential dangers. Here are the relevant explanations: 1. Visibility in foggy weather: With poor visibility in foggy conditions, drivers can only determine the positions of other vehicles through sound. Therefore, honking is frequently used as a means of "communication" in foggy weather. When hearing other vehicles honk, drivers should also inform others of their own position to prevent accidents caused by poor visibility. 2. How the horn works: The horn produces sound through the vibration of a metal diaphragm. A car's electric horn consists of an iron core, a magnetic coil, contacts, an armature, a diaphragm, etc. When the driver presses the horn switch, current flows through the contacts to the coil, generating a magnetic force that pulls the armature, forcing the diaphragm to move.

I believe honking the horn frequently in heavy fog is primarily for safety reasons, as poor visibility means others may not see your car at all. I've experienced this several times on highways where dense fog reduced visibility to just a few meters. Frequent honking can promptly alert vehicles ahead or pedestrians on the roadside, preventing rear-end collisions or accidents. At the same time, this is part of basic driving knowledge – combining it with turning on front and rear fog lights, maintaining a safe distance, and reducing speed is essential for truly enhancing safety. Relying solely on the horn without slowing down increases risks. Remember, driving in fog requires full concentration and anticipating potential hazards. I recommend testing your horn before entering any foggy area, as it's your audible signal that could be lifesaving in critical moments, but avoid excessive honking to prevent unnecessary noise pollution.

Will points be deducted for overloading a sedan?

Overloading a sedan will result in point deductions, with varying penalties depending on the circumstances. Here are the relevant details: Detailed information: Driving an operational passenger vehicle (excluding buses) or school bus with passengers exceeding the approved capacity by less than 20%, or driving other passenger vehicles with passengers exceeding the approved capacity by more than 20%, will result in a 6-point deduction; driving passenger vehicles other than operational passenger vehicles (excluding buses) or school buses with passengers exceeding the approved capacity by less than 20%, will result in a 3-point deduction. Impact of overloading: Vehicle overloading severely damages road infrastructure. Increased load mass leads to greater inertia, longer braking distances, and higher risks. Drivers operating overloaded vehicles often experience increased psychological stress and mental pressure, making them prone to operational errors, affecting driving safety, and potentially causing traffic accidents. Overloaded vehicles cannot maintain normal driving speeds, occupying lanes for extended periods, directly impacting road traffic flow.

What is the fuel consumption per kilometer for a semi-trailer?

Under standard road conditions and proper loading, the fuel consumption ranges between 36L/100km to 45L/100km. Below are relevant details: Introduction to semi-trailers: A semi-trailer is a trailer with axles positioned behind the vehicle's center of gravity (when evenly loaded) and equipped with a coupling device that transmits both horizontal and vertical forces to the tractor. Precautions for highway driving: Avoid distractions. During this time, no one can predict what might happen. Once attention is diverted, unexpected situations ahead may leave insufficient time to react, potentially leading to accidents. Control your speed. Each lane on the highway has a fixed maximum speed limit. Exceeding the limit not only results in penalty points and fines but, more importantly, poses significant safety hazards. Higher speeds increase the vehicle's inertia and extend the braking distance. Signal lane changes in advance. This indicates your driving intentions to other vehicles. Be sure to use your turn signals early to provide ample warning.

Which Gear to Use for Curve Driving?

Curve driving uses 1st or 2nd gear. Below are relevant details: Introduction to Curve Driving: Curve driving, commonly known as S-curve, is an assessment point in Subject 2 of the driver's test. The test requires the vehicle to drive on an S-shaped road of specified width without pressing the edge lines and with smooth steering. It assesses the driver's ability to maneuver the steering and control the vehicle during curve driving. The purpose is to develop the driver's steering skills and mastery of wheel trajectory. Precautions: When entering the curve, reduce speed in advance and keep to the right. Avoid turning the steering wheel too quickly or sharply. Choose the path with the largest turning radius whenever possible. Avoid using the brake, especially emergency braking. Check the rearview mirror—it's essential to learn how to use it properly—and master the clutch by using semi-clutch engagement.

Is an ID card required for the simulated driving test of Subject Two?

An ID card is not required for the simulated driving test of Subject Two. Below is the relevant information: Introduction to Subject Two: Subject Two, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. The C1 car test includes five mandatory items: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curve. Points to note: Pay attention to details, remember the entire test process and procedures, and operate according to the rules. Avoid mistakes such as forgetting to fasten the seat belt, forgetting to turn on the turn signal, or forgetting to turn off the turn signal. After completing the test, do not rush to get out of the car or make any sudden movements. Wait until you hear the voice announcement "Test completed, result passed" before getting out of the car, otherwise you may fail.

Is it safe to store lithium batteries in the trunk during summer?

Storing lithium batteries in the trunk during summer is not safe. Here are relevant details: Introduction to lithium batteries: Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive/negative electrode materials and non-aqueous electrolyte solutions. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. Precautions for using lithium batteries: Do not place lithium batteries in any location exposed to direct sunlight. Keep lithium batteries away from heat sources. Before using lithium batteries, be sure to read the user manual and any warnings on the device. Do not spill water, saltwater, juice, or other liquids on lithium-ion batteries. Use battery chargers and AC adapters specifically designed for lithium batteries. Lithium batteries have designated positive and negative terminal orientations. Do not directly connect lithium batteries to a car's power socket or cigarette lighter socket without using a battery charger.
