Does ETC need to be connected to a power source?

Installing ETC does not require an external power connection as it uses its own built-in power source. The ETC electronic tag consumes power, but it does not need to be charged during normal use because there is a solar panel on the back of the battery that can charge it automatically. During installation, it is necessary to avoid the black areas on the windshield. The built-in power source of ETC typically has a lifespan of 3-5 years. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed. Applicants must be between 18 and 60 years old, and the vehicle must be registered under an individual's name. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; and the vehicle that needs to be equipped with ETC. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, it settles the toll with the bank in the background, allowing the vehicle to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: Avoid the hassle of waiting in line; Green and eco-friendly: Low-carbon solution, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions; Cost-saving: Reduces vehicle start-up and braking frequency, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Efficiency improvement: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What Causes Car Brake Noise?

Here are the reasons for car brake noise: 1. During brake disc break-in period; 2. Normal activation of ABS system; 3. Foreign objects between brake pads and discs; 4. Rust on brake disc surface; 5. Excessive wear of brake pads or discs; 6. Assembly issues; 7. Problems with new brake pads. Below is extended information about car brakes: 1. The braking system consists of control system, hydraulic system and booster system. The brake device generates friction between the brake pads and wheel drum or disc, converting the kinetic energy during car movement into heat energy during the friction process. 2. The principle of braking system is to create enormous friction that converts vehicle's kinetic energy into heat energy.

What is the Safe Driving Distance?

Safe driving distance refers to the necessary gap that a following vehicle maintains from the vehicle ahead to avoid accidental collisions while driving. Below is an explanation of safe driving distances: 1. Maintain 40 meters at 40 km/h; 2. Maintain 60 meters at 60 km/h; 3. Maintain 10 meters when speed drops to 20 km/h; 4. Maintain 5 meters at 15 km/h. Here is additional material on judging distances while driving: 1. When the lower edge of the rear wheel of the vehicle ahead aligns with the lower edge of the windshield, the distance is approximately 3 to 5 meters; 2. When the lower edge of the front bumper aligns with the lower edge of the windshield, the distance is about 2 meters; 3. When the upper edge of the front bumper aligns with the lower edge of the windshield, the distance is approximately 0.5 to 1 meter.

How to Use Lights When Driving a Motor Vehicle at Night?

When driving a motor vehicle at night without street lights, poor lighting, or under conditions of low visibility such as fog, rain, snow, dust, or hail, the headlights, position lights, and rear lights should be turned on. However, high beams should not be used when a following vehicle is driving close behind another vehicle in the same direction. During foggy conditions, fog lights and hazard warning flashers should be activated. Additional Information: 1. Article 48 of the "Road Traffic Safety Law" states that when meeting another vehicle at night, drivers should switch to low beams at least 150 meters away from the oncoming vehicle. On narrow roads, narrow bridges, or when meeting non-motorized vehicles, low beams must be used. 2. Article 51 specifies that when a motor vehicle passes through an intersection controlled by traffic signals, it should proceed as follows: When turning left, the vehicle should turn from the left side near the center of the intersection. Turn signals should be activated when turning, and low beams should be used when driving at night. 3. Article 59 states that when a motor vehicle passes through sharp curves, slopes, arched bridges, pedestrian crossings, or uncontrolled intersections at night, it should alternately use high and low beams as a signal. When approaching sections that affect safe visibility, such as sharp curves or the top of a slope, or when overtaking or encountering an emergency, the vehicle should slow down and sound the horn as a warning. 4. Article 60 requires that if a motor vehicle breaks down or is involved in an accident on the road, obstructing traffic and making it difficult to move, the hazard warning flashers should be activated, and a warning sign should be placed 50 to 100 meters behind the vehicle. At night, position lights and rear lights should also be turned on simultaneously. 5. Article 61 stipulates that when towing a faulty motor vehicle, the following rules must be observed: Both the towing vehicle and the towed vehicle should have their hazard warning flashers activated.

How to Paint a Car?

Here are the steps for car painting: 1. Clean the car body with water, use a sanding block to flatten the sandpaper, then wet-sand the scratches until the edges are smooth. 2. Apply putty evenly over the scratches using a spreader and let it dry completely. 3. After drying, wet-sand the putty with sandpaper until the putty surface is level with the paint surface. 4. Mask the surrounding parts of the scratches, and once properly masked, you can begin painting. Below are the precautions during painting: 1. Hold the spray gun about 20 cm away from the surface and spray evenly in multiple passes for better results. When applying multiple coats, ensure each subsequent coat is applied after at least 10 minutes to allow the paint to dry and avoid sagging. If sagging occurs, wait for it to dry, then sand it smooth and respray from a distance. After the paint is completely dry, apply a clear coat to enhance gloss, protect the paint, and improve durability. 2. Maintain a perpendicular spray pattern to the surface. For a wetter, darker, and thicker coat, spray closer; for a drier, lighter, and thinner coat, spray farther away. For uniform paint thickness, use a cross-spray method followed by horizontal spraying.

How Long Does It Take to Wax a Car?

Depending on the waxing method, the time required for waxing will vary. Generally, manual waxing can be completed in about half an hour, while machine waxing may take around one and a half hours. If polishing and waxing are combined, the process will take relatively longer, approximately three hours. Proper waxing can make the car's paint shine brighter and extend the lifespan of the paint surface. Here are some precautions for waxing: 1. Choose car wax carefully: There are many types of car wax, and the selection should be based on the car's quality. If you're unsure, consult professionals at a 4S store to avoid unnecessary losses due to incorrect wax selection. 2. More expensive doesn't mean better: This is a common mistake when choosing car wax. The performance of waxes varies, leading to different effects. Improper wax selection can cause paint discoloration, so choose wax based on the car's driving environment and age. 3. Avoid frequent waxing: While waxing enhances paint brightness, excessive waxing can have the opposite effect, especially for new cars. New cars come with a protective film from the factory, and waxing too soon can damage this layer, resulting in unnecessary losses.
