How many seconds after the light turns red does the camera start capturing?

The camera starts capturing two seconds after the green light directly turns red. If a motor vehicle crosses the stop line under a green light and gets stuck in the middle of the road when the light turns red, it will not be considered as running a red light. Here is the relevant information: Penalty: Running a red light refers to the act of a motor vehicle violating the prohibition of passage during the red light phase at a signal-controlled intersection or road section, crossing the stop line and continuing to move. According to the latest revised "Regulations on the Application and Use of Motor Vehicle Driving Licenses", running a red light results in 6 penalty points and a fine. Evidence of running a red light: The determination of "running a red light" is based on passing through the entire intersection, generally requiring three photos as evidence. The first photo is taken when the wheels cross the stop line, the second when passing through the intersection, and the third after passing through the intersection, all of which must be taken during the red light phase. Only when these conditions are met will the electronic eye record it as running a red light.

Is it a violation if the front wheels cross the stop line?

If a vehicle has just crossed the stop line when the light turns red and stops immediately, this kind of running a red light will not be penalized. However, if there is obvious movement after crossing the line, it will be subject to penalties. New regulations on running red lights: A vehicle is considered to have run a red light only if it drives past the stop line, enters the intersection, and continues through the intersection. Ways to avoid running red lights while driving: When there are arrow signals, follow the arrow lights; otherwise, follow the circular lights. When the red light is on, the front of the vehicle must not cross the stop line. When the yellow light is on, the front of the vehicle must not cross the stop line. When the green light just starts flashing, if you are close and moving fast, you should proceed, as braking might not stop you in time to avoid crossing the stop line; if you are far or moving slowly, you should stop.

What does DCT transmission mean?

DTC transmission is short for dual-clutch transmission. It refers to two sets of clutches. The one cooled by air is called dry dual-clutch, while the one cooled by oil is called wet dual-clutch. DCT Transmission: The main body of a DCT transmission is a manual transmission, which can also be considered an upgraded version of a manual transmission. The DCT transmission has two sets of clutches, primarily responsible for shifting odd-numbered gears and even-numbered gears (including neutral gear), respectively. During operation, these two sets of clutch plates work alternately to complete the tasks of upshifting and downshifting in the DCT transmission. Generating significant heat: During the shifting process, the friction plates of the two clutches generate a substantial amount of heat due to intense friction. This is especially true when driving in congested urban areas, where frequent stop-and-go conditions occur. The transmission shifts gears more frequently, requiring the vehicle's transmission clutches to work continuously, thus causing the DCT transmission to generate a significant amount of heat.

Why Do Cars Need Frequent Oil Changes?

Cars require frequent oil changes for the following reasons: 1. To improve and enhance lubrication for the engine's moving friction components; 2. To extend the engine's service life; 3. To optimize the engine's lubrication conditions and reduce friction between moving parts. Precautions for oil changes include: 1. Perform the change when the engine is warm to ensure thorough drainage of old oil; 2. Add new oil and ensure the correct oil level; 3. Start the engine after adding oil and inspect all components for leaks. The oil change procedure consists of: 1. Lift the vehicle, remove the underbody cover, and place a ~10L container beneath the drain plug; 2. Loosen the drain plug, use an air gun to blow through the oil filler opening for two minutes, then tighten the drain plug and wipe with tissue to check for leaks; 3. Reinstall the underbody cover, lower the vehicle, and use a funnel to add new oil through the filler opening.

What Causes High Water Temperature in Excavators?

Reasons for high water temperature in excavators include: failure of the coolant circulation water pump, which prevents water in the radiator from circulating, leading to high temperature; the excavator's radiator surface being covered with dust and mud, blocking the cooling channels and reducing cooling capacity, resulting in high temperature; use of unqualified coolant that clogs the radiator or insufficient coolant, causing inadequate cooling capacity and high temperature. Introduction to the Engine Radiator: The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator where the heat is dissipated, and then returns to the water jacket to circulate, maintaining the temperature. It is a part of the car engine. Working Principle of the Engine Radiator: The radiator is a crucial component of a water-cooled engine. As an important part of the water-cooled engine's cooling circuit, it absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, the temperature does not rise significantly after absorbing heat from the engine block. Therefore, the engine's heat is transferred through the liquid cooling circuit, using water as the heat carrier, and then dissipated through large-area cooling fins via convection to maintain the engine's optimal operating temperature.

What are the reasons why a car always runs out of battery?

The reasons why a car always runs out of battery are: 1. The car has been left unused for a long time, during which the battery self-discharges; 2. The electrical appliances inside the car were not turned off during use, resulting in prolonged discharge; 3. The car battery has aged. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine stops running or is at low idle, it powers the car's electrical equipment; 3. When the generator's output is insufficient, it can assist in supplying power to the electrical equipment; 4. It mitigates voltage surges in the electrical system, protecting the car's electronic devices; 5. It can store excess electricity generated by the alternator.
