What are the reasons for the ETC device not lighting up after inserting the card?

etc device not lighting up after inserting the card is due to device malfunction or incorrect card insertion method. The method to check if the ETC device is working properly is: After receiving the ETC device, first check if the ETC card and electronic tag are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly light up. If the OLED screen displays "Label Invalid" or "Please Insert Card," it indicates the device is functioning normally. The advantages of installing ETC include: 1. Saving time, eliminating the hassle of waiting in line; 2. Green and low-carbon, as vehicles can pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; 3. Cost savings, as vehicles can reduce the frequency of starting or braking, lowering wear and fuel consumption, and users can also enjoy discounts on toll fees.

Can you overtake from the right side when driving a motor vehicle?

Overtaking from the right side is not allowed. Here are the relevant regulations: 1. Traffic laws stipulate: When overtaking, motor vehicles should turn on the left turn signal in advance, switch between high and low beams, or sound the horn. 2. On roads without a center line or with only one motor vehicle lane in the same direction, when the leading vehicle receives an overtaking signal from the following vehicle, it should reduce speed and move to the right to give way if conditions permit. The following vehicle should overtake from the left side of the leading vehicle after confirming a sufficient safe distance, and then turn on the right turn signal to return to the original lane after maintaining a necessary safe distance from the overtaken vehicle. 3. However, if there are two or more motor vehicle lanes in the same direction, a vehicle traveling in the right lane may overtake a vehicle in the left lane.

What does the L mean on an automatic car?

L in an automatic car stands for Low gear. Here are the relevant introductions: 1. When in L gear, the transmission will remain in 1st gear, adjusting the power input and output rotation ratio to low speed and high torque, thereby obtaining strong traction. 2. Introduction to automatic car gears: P gear is the parking gear, used when the vehicle is parked for a long time; R gear is the reverse gear, used when the vehicle needs to move backward; N gear is the neutral gear, used when the vehicle is parked for a short time without turning off the engine; D gear is the drive gear, when the gear lever is placed in D gear, the vehicle will automatically switch gears based on throttle opening and speed data; S gear is the sport mode, making the vehicle drive more sporty; M gear refers to the manual mode, when the gear lever is shifted into M gear, gear shifting is done manually by the driver.

Do cars need maintenance every month?

Car maintenance is not required every month. Here are the relevant details: 1. Generally, a routine maintenance is performed every 5,000 kilometers or every six months, which mainly includes changing the engine oil, oil filter, and air filter. The maintenance every six months involves cleaning the exterior of the engine, taking care to waterproof the electrical components during cleaning. 2. If the electrical components have high waterproof requirements, avoid using high-pressure or high-temperature water jets to clean the engine. Instead, use a brush with cleaning solution to clean the engine exterior. 3. The fuel filter and air filter should be replaced every 10,000 kilometers, while the cabin air filter should be replaced every year or approximately every 20,000 kilometers. 4. A full fluid replacement is required at 40,000 kilometers. 5. During each maintenance session, the transmission should be inspected. Although transmission fluid does not need to be replaced, the fluid level should be checked regularly, and non-original fluid should not be used without authorization.

How is running a red light determined?

It is determined by capturing three photos through electronic cameras. The first photo shows the vehicle crossing the stop line at the intersection, including the red light and the license plate number. The second photo shows the vehicle completely passing the stop line, including the red light and the license plate number. The third photo shows the vehicle continuing to move, mainly by comparing the change in the vehicle's position from the second photo, including the red light and the license plate number. Capturing these three photos can determine that the vehicle has run a red light. According to Article 26 of the Road Traffic Safety Law, traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to pass, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and if a vehicle passes through an intersection during a red light, it constitutes the traffic violation of running a red light. The following points can help avoid running a red light: First look at the arrow light, then the circular light: Currently, there are two types of indicator lights: arrow traffic lights and circular indicator traffic lights. When there is an arrow light, first observe the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, you can turn right; when encountering an arrow signal light with a red right-turn arrow, you cannot turn right, otherwise it will be penalized as running a red light. Brake in time: When the red light turns on, do not let the front of the vehicle cross the stop line. If the front wheels accidentally cross and the rear wheels follow, the electronic camera will capture it, and it will be penalized as running a red light. If the front wheels have just crossed the stop line when the light turns red, do not proceed through the intersection; wait for the green light before proceeding. Check the green light countdown before proceeding: When the green light flashes, if there is a countdown, you can judge based on the countdown. If there is no countdown and the vehicle is close to the intersection with high speed, you can proceed to avoid running a red light due to untimely braking. If the speed is slow and the vehicle is far from the intersection, brake immediately to stop and avoid running a red light. Article 38 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China states: When the green light is on, vehicles are permitted to pass, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to pass. When the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signal indications. When the red light is on, right-turning vehicles may pass if they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not considered illegal under the following circumstances: Extreme weather: When visibility is very low, and even electronic police cannot clearly see the traffic lights. Photos of the violation may be blurry, and if you accidentally run a red light, traffic police will not impose penalties. Emergency situations: When transporting a critically ill patient to the hospital, you may run many red lights, and 12 points may not be enough. After delivering the patient, provide proof from the hospital or the person being helped to the traffic police for verification. If confirmed, the violation record can be cleared. If possible, it is best to call an ambulance to avoid accidents caused by running red lights. Traffic police direction: During peak hours, traffic police may temporarily direct traffic at important intersections. Drivers should follow the gestures of the traffic police. Yielding to special vehicles: Yielding to special vehicles such as ambulances or fire trucks. If captured by surveillance cameras while yielding, the running of the red light will not be recorded during manual review. Even if recorded, you can apply for reconsideration at the traffic police department. The traffic police department states that according to Article 38 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, when the yellow light flashes at an intersection, vehicles that have already crossed the stop line may continue to pass. If the yellow light is already on and you still rush to pass, it will be considered running a red light if captured.

Is Adding a Light Enhancer Effective for Cars?

Adding a light enhancer to a car is effective. Here are the relevant details: 1. The principle of a light enhancer is to stabilize the voltage at 14.2V, essentially functioning as a DC-to-DC module. The light enhancer provides a soft start for the voltage, which offers some protection to the bulbs. However, it may reduce the bulb's lifespan by about 15% in the long run, though this impact is negligible. 2. A car's light enhancer system includes the generator, high/low beam switch, headlights, high beam relay, and low beam relay. The two relays are connected in series and installed near the generator or headlights at the front of the car, with their series connection point grounded. One end of the high beam relay is connected to the high beam control output of the high/low beam switch, and its normally open contact is connected between the generator and the high beam filaments of the two headlights. Similarly, one end of the low beam relay is connected to the low beam control output of the high/low beam switch, and its normally open contact is connected between the generator and the low beam filaments of the two headlights. This setup shortens the current transmission distance from the generator to the headlights, thereby reducing line voltage drop, increasing the headlight illumination intensity, and enhancing nighttime driving safety.
