Will I get points deducted for running a red light at 80 km/h?

Driving at 80 km/h through a traffic light exceeds the speed limit set for intersections and constitutes a speeding violation, which will result in a fine ranging from 20 to 200 yuan. More details are as follows: 1. According to Article 42 of the "Road Traffic Safety Law of the People's Republic of China": When driving on the road, motor vehicles shall not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, a safe speed should be maintained. When driving at night or on sections prone to danger, or under weather conditions such as sandstorms, hail, rain, snow, fog, or ice, the driving speed should be reduced. 2. Article 44: When passing through intersections, motor vehicles shall proceed according to traffic signals, signs, markings, or the direction of traffic police. When passing through intersections without traffic signals, signs, markings, or traffic police direction, drivers should slow down and yield to pedestrians and vehicles with the right of way.

What Causes the Lower Part of the Wiper to Shake?

The reasons and solutions for wiper shaking are as follows: 1. Foreign objects between the wiper blade and windshield causing shaking: When the wiper is turned on, there may be a sharp friction sound between the wiper blade and the windshield. The owner can check and clean any foreign objects on the wiper blade or underneath the wiper to ensure the area is clean. 2. Friction in the wiper linkage bushing causing shaking: Over time, the wiper linkage mechanism may age, the wiper arm spring may lose elasticity, and the bushing may wear out or even fall off. Please inspect the wiper arm or linkage bushing. 3. Wiper motor causing shaking: If the wiper motor itself lacks power and shakes, it may be a sign that the motor is nearing the end of its lifespan. It is recommended to have a more detailed inspection at a professional repair shop.

What Causes High Engine Temperature?

Here are several common causes of engine overheating: 1. Insufficient coolant leading to high temperature: Coolant deficiency is the easiest to identify—simply open the engine hood and check the coolant level. If the coolant level is below the "MIN" mark, it indicates insufficient coolant. 2. Dirty radiator causing temperature rise: If the engine compartment accumulates excessive dust due to long-term lack of cleaning, it can lead to poor heat dissipation in the radiator, resulting in high engine temperature. Generally, overheating caused by excessive dust on the radiator can be resolved by simply cleaning the dust off the radiator. 3. Thermostat malfunction causing temperature rise: The thermostat's function is to automatically adjust the amount of water entering the radiator based on the coolant temperature, altering the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. If high temperature is noticed during normal driving, open the engine hood and touch the radiator's inlet and outlet pipes to check for a temperature difference. If a temperature difference exists, it indicates a faulty thermostat that cannot function properly, leading to high engine temperature. 4. Electric fan malfunction causing temperature rise: Fan failure is another cause of engine overheating. A non-operational fan leads to insufficient radiator cooling, causing high engine temperature. There are many reasons for fan failure, including fan motor malfunction, thermostat failure, or a blown fan fuse, all of which can prevent the fan from operating.

What is the sound when hitting the radar?

Radar emits a continuous beep when hitting an obstacle. Here are the relevant details: 1. Reversing Radar: The reversing radar, also known as "reverse anti-collision radar" or "parking assist device", mainly consists of ultrasonic sensors, a controller, and a display. 2. Working Principle: When reversing, the reversing radar uses the ultrasonic principle. The probe installed on the rear bumper sends ultrasonic waves that reflect off obstacles, calculates the actual distance between the vehicle body and the obstacle, and then alerts the driver, making parking or reversing easier and safer.

Which institutions can inspect used cars?

Seek independent third-party vehicle inspection institutions with nationwide chains for more reliable results. Below are methods to check if a used car has been in an accident: 1. Check the glass production date: Normally, glass isn't replaced, so checking its production date can be telling. The date is usually in a format of numbers + dots, where numbers represent the year and dots represent the month. 2. Examine the wear on the frame: If the car has been in a major accident, the body frame will show varying degrees of dents and misalignment, so assessing the frame's condition can indicate past accidents. 3. Inspect the screws: Look at the screws on the hood, radiator support, and door connections. If any of these screws show abnormalities, it's a strong indication the car was in a major accident. 4. Review maintenance records: Check the maintenance records at authorized dealerships (4S shops). Any accident repairs done at a 4S shop will be systematically recorded.

Standard Values for Intake Air Temperature Sensor?

Under normal conditions, the resistance is approximately 2-3 kiloohms at 20°C and about 0.4-0.7 kiloohms at 80°C. If the measured values do not meet the specified requirements, the sensor should be replaced. When the intake air temperature sensor installed inside the air flow sensor is damaged, the air flow sensor should be replaced. Below is additional information about the intake air temperature sensor: 1. Function: The intake air temperature sensor is essentially a negative temperature coefficient thermistor. Its role is to transmit the intake air temperature to the ECU in the form of a voltage signal, which the ECU then uses as a correction signal for fuel injection and ignition. 2. Location: The intake air temperature sensor is typically installed in the intake pipe or within the air flow meter. 3. Damage Consequences: If the engine's intake air temperature sensor is damaged, the ECU not only fails to accurately use it as a correction signal for fuel injection and ignition but may also receive incorrect information, leading to issues such as difficulty starting the engine, unstable idle speed, and increased exhaust emissions.
