Why are the high beams of a car lower on the left and higher on the right?

In China, vehicles drive on the right side of the road, with oncoming traffic on the left. The left headlight is adjusted to a lower position to ensure the visibility of oncoming drivers, effectively reducing the occurrence of accidents. The right headlight is set higher to illuminate farther distances. On one hand, this helps drivers detect pedestrians ahead earlier, ensuring safer driving. On the other hand, it also alerts non-motorized vehicles or pedestrians to the presence of approaching vehicles from behind, allowing for a safety buffer. Below are some related details: 1. High beams: High beams adjust the intensity of light based on the distance of the filament. The high beam is focused at its focal point, emitting parallel light that is more concentrated and brighter, capable of illuminating distant and high objects. Low beams are positioned beyond the focal point, between 1 to 2 times the focal distance, emitting divergent light that covers a larger area at closer distances. 2. Precautions: When driving at night, it is important to use lights appropriately to avoid compromising the safety of other drivers.

Is the highway toll free during Mid-Autumn Festival?

No. According to the "Implementation Plan for Exempting Toll Fees for Small Passenger Vehicles on Major Holidays" issued by the state, the holidays for free highway travel are limited to four national statutory holidays: Spring Festival, Qingming Festival, Labor Day, and National Day. Mid-Autumn Festival is not included in the list of holidays for free highway travel. Below is some relevant information: 1. Highway tolls: Due to varying economic development levels, GDP, and road grades across different regions in China, highway toll standards differ. More expensive provinces charge around 0.9 yuan per kilometer, while cheaper ones charge 0.3 yuan per kilometer. 2. Precautions: Before entering the highway, be sure to check all vehicle lights, as highway driving at night relies on car lighting. Also, clean the front windshield thoroughly and remove anything that obstructs visibility. Otherwise, reflections or blocked vision may occur under the headlights of other vehicles.

What to Do When Brakes Suddenly Fail While Driving?

In case of sudden brake failure, utilize the dedicated emergency lanes on the roadside to decelerate and stop the vehicle, or scrape the car body against rocks or trees by the road while shifting to a lower gear. Below is more information regarding brake failure: 1. Causes: (1) No brake fluid in the master cylinder. (2) Damaged or flipped master cylinder cup. (3) Severe rupture or disconnection of brake lines. 2. Diagnosis: If brake failure occurs, immediately stop and inspect. First, check for any leaking brake fluid. If there is severe leakage from the master cylinder push rod dust cover, it is mostly due to a flipped or severely damaged master cylinder cup. If a large amount of brake fluid is found at the edge of a wheel's brake drum, it indicates that the wheel cylinder cup is flipped or severely damaged. Leakage in the brake lines is usually clearly visible. If there is no sign of brake fluid leakage, check whether the brake fluid in the master cylinder reservoir is sufficient.

What Causes the Noise from a Compressor Stuck in the Cylinder?

Reasons for the noise from a compressor stuck in the cylinder: 1. Insufficient lubrication due to the failure of the refrigeration oil to rise, leading to increased friction and the compressor's rotating shaft getting stuck, resulting in noise; 2. Presence of dust or impurities in the pipeline, causing the moving surfaces to seize; 3. Mechanical failure causing the compressor to get stuck and produce noise. Methods to handle a stuck compressor: 1. Tapping method: Use a wooden hammer to firmly tap the three welding points on the compressor when starting it, being careful to control the force to avoid deformation; 2. Capacitor starting method: Add an additional capacitor in parallel with the original one to increase the starting force and get the compressor running; 3. Pressure relief method: Release some of the Freon to reduce the pressure.

How to Determine Car Tire Pressure?

Methods to determine car tire pressure: Using a tire pressure gauge can accurately measure the air pressure in car tires. Most vehicles are equipped with a tire pressure monitoring system, which displays the tire pressure on the dashboard. Strictly speaking, tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a crucial role in the performance and power of the vehicle. Tires are circular elastic rubber products mounted on various vehicles for rolling contact with the ground, usually installed on metal rims. They support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. During operation, tires endure various deformations, loads, forces, and high and low temperatures, so they must possess high load-bearing, traction, and cushioning capabilities.

Can the ETC card be removed when not in use?

When the ETC is not needed, users can remove the ETC card. Especially for ETC cards with financial functions, such as those enabled with UnionPay QuickPass and small-amount quick payment features, it is advisable to remove them after use to avoid the risk of being fraudulently charged. ETC is an electronic toll collection system, also known as an automatic road charging system. It is specifically designed for toll roads, commonly found on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC charging principle: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's on-board electronic tag (installed on the windshield) and the microwave antenna in the ETC lane at toll stations, the system uses computer networking technology to settle payments with banks in the background. This allows vehicles to pay tolls without stopping at toll booths, operating on the principle of "pass first, deduct later." Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by allowing vehicles to pass toll stations without stopping, thereby lowering pollution; Cost-saving: Reduces vehicle wear and fuel consumption by minimizing frequent starts and stops; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC systems faster, more advanced, and 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, intercity transportation cards will be basically interoperable in key city clusters, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators to "achieve a 50% ETC usage rate for road passenger vehicles by 2020." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC adoption for trucks. Future developments will explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation directions, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC usage.
