How to Distinguish Between China 5 and China 6 Emission Standards for Vehicles?

China 6 and China 5 mainly differ in the content of emissions. When purchasing a new car, you can check the vehicle's factory certificate and the environmental standard list to distinguish between them. Below is some information about China 6 and China 5: 1. The primary difference between China 6 and China 5 lies in the emission content, with China 6 standards being significantly lower than China 5 standards. 2. The carbon monoxide emission limit for gasoline vehicles under China 5 standards is 1000 mg/km, while under China 6 standards, it is 700 mg/km. 3. The emission limits of 'China 6 standards' are approximately 40% to 50% stricter than those of 'China 5 standards'.

What Type of Driver's License is Required for Agricultural Vehicles?

Agricultural vehicles generally require a C3 driver's license. Here is some information about the C3 driver's license: 1. The C3 driver's license is issued by the vehicle management office as a certification for operating low-speed trucks. With a C3 license, you can drive agricultural transport vehicles or light-duty trucks with a length of less than 6 meters and a total weight of less than 4500KG. Additionally, a C3 license also permits the operation of three-wheeled vehicles covered under the C4 license. 2. Low-speed refers to a maximum speed not exceeding 70km/h. These vehicles are generally not allowed on urban main roads and are commonly seen in rural or suburban areas.

How to Solve the Problem of Unstable Car Idling Speed Fluctuating Up and Down?

Solutions to unstable car idling speed fluctuating up and down: adjust the throttle valve and idle speed to ensure the engine operates at the lowest stable speed. The throttle valve is a controllable valve that regulates air intake into the engine, available in two types: traditional cable-operated and electronic throttle. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture for combustion and power generation. It connects to the air filter at the top and the engine block at the bottom. The responsiveness of the car's acceleration is closely related to the cleanliness of the throttle valve. Car idling refers to an operating condition where the engine runs without load, meaning the car is in neutral gear. The engine speed during idling is called the idle speed, which can be adjusted by altering the throttle opening size. Idling essentially means the engine is running but not performing work.

Does driving over a crosswalk count as running a red light?

If the vehicle stops at the crosswalk without continuing to drive, it does not count as running a red light but rather as overstepping the stop line. According to Article 4, Item 5 of the 'Scoring Standards for Road Traffic Safety Violations': Failing to drive or stop as required when passing through an intersection results in a 2-point deduction. The act of running a red light is clearly defined in the 'Road Traffic Safety Law.' Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition, a green light indicates permission, and a yellow light serves as a warning. A red light is a traffic signal that prohibits passage. If a vehicle proceeds through an intersection when the light is red, it constitutes the traffic violation of running a red light. Running a red light refers to the act where, when the vehicle is within the stop line and the forward direction is already a red light, the vehicle continues to move forward until both its front and rear wheels have completely crossed the stop line. This is determined by capturing three photos via electronic cameras: A photo of the vehicle crossing the intersection stop line, including the red light and license plate number. A photo of the vehicle completely crossing the stop line, including the red light and license plate number. A photo showing the vehicle continuing to move, with a comparison to check for changes in the vehicle's position, including the red light and license plate number. Capturing these three photos confirms the act of running a red light. Running a red light is not considered illegal under the following circumstances: Yielding to special vehicles: Yielding to ambulances, fire trucks, or other special vehicles. If captured by surveillance cameras while yielding, manual review will not record the act as running a red light. Even if recorded, you can apply for reconsideration with the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights. Photos of the violation may be blurry, and accidental running of a red light will not be penalized by traffic police. Emergency situations: After delivering a patient with a critical condition, providing proof from the hospital or the person being assisted to the traffic police for verification can result in the removal of the violation record. If possible, it is best to call an ambulance to avoid traffic accidents caused by running a red light. Traffic police direction: During peak hours, traffic police may temporarily direct traffic at important intersections. Drivers must follow the gestures of the traffic police.

How much should the steering wheel be turned for a general U-turn?

When making a U-turn, the steering wheel is typically turned more than 90 degrees and then adjusted to half a turn, aligning the front of the vehicle with the center of the road. The steering process should not be too fast, and the wheel should not be turned to the extreme. Adjust the steering angle according to the turning angle of the vehicle's front, as the angle and speed are related. Remember to maintain a low speed during the U-turn. Here are the key points to note for a U-turn: 1. At intersections with U-turn signals, proceed to the intersection and follow the dedicated U-turn signal or ground markings if available. 2. At intersections without a U-turn signal but with a left-turn signal, generally, as long as there is no no-U-turn sign or a separate U-turn signal, vehicles can make a U-turn at any time without affecting normal traffic flow and ensuring safety. Typically, the central divider on regular roads changes from a solid line to a dashed line near the intersection, allowing U-turns in this area. 3. Yellow grid areas indicate no stopping. If the traffic light is red ahead, vehicles behind should avoid this area. However, U-turns are permitted in this zone as long as there is no central barrier. 4. Intersections with no-left-turn signs prohibit left turns, but since U-turns require a similar path to left turns and occupy the opposite lane, U-turns are also prohibited at these intersections. 5. Pedestrian crossing areas, although usually not marked with no-U-turn signs, are equivalent to sidewalks and do not allow U-turns. 6. The leftmost lane with only a straight arrow: Near intersections, lanes are marked with arrows to guide vehicle direction. If the leftmost lane has only a straight arrow, U-turns are not allowed even if there is no no-U-turn sign.

What are the consequences of not having a car inspected on time?

The consequences of not having a car inspected on time: Vehicles that fail to undergo annual inspection on time are not allowed on the road; driving a vehicle without timely inspection will result in 3 penalty points and a fine; if an accident occurs involving a vehicle that has not been inspected, the party involved will bear full or primary responsibility, and the insurance company will not compensate; driving without timely inspection is considered illegal driving and may lead to vehicle impoundment; according to the "Mandatory Scrapping Standards for Motor Vehicles," if a vehicle fails to obtain an inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection period, it will be forcibly scrapped. The procedure for annual inspection: First, after submitting the inspection application, the vehicle undergoes an online inspection. The vehicle is driven into an automatic inspection area to test exhaust emissions, speed, lights, side slip, and chassis for compliance with standards. Only when all items pass can the vehicle proceed. Next is the appearance inspection, verifying the vehicle's license plate, type, body color, engine number, VIN code, and frame number for accuracy. Then, the vehicle's exterior is inspected, including details such as the bumper, engine compartment, rearview mirrors, lower mirrors, window glass, paint, engine operation condition, and the interior of passenger vehicles and wheels. Finally, the owner can obtain the inspection report and application form from the inspector. If all inspection items pass, the owner can proceed to pay the inspection fee and receive the vehicle license and qualification label; if any items fail, the owner must repair the vehicle and participate in a re-inspection until it passes before proceeding with the visa procedures.
