Should You Use Internal or External Air Circulation in Winter?

What are the differences between National 5 and National 6 emission standards for passenger cars?

The differences between National 5 and National 6 emission standards for passenger cars lie in their control levels, release dates, and issuing authorities. Here are the specific differences between National 5 and National 6 emission standards for passenger cars: Different control levels: The emission control level of National 5 standard is equivalent to the European Phase 5 emission standard currently in implementation. The National 6 standard for motor vehicle pollutant emissions is formulated to prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. Different release dates: The National 5 standard was released on September 17, 2013. The National 6 standard for motor vehicle pollutant emissions was released on June 22, 2018 (for heavy-duty diesel vehicles). Different issuing authorities: The National 5 standard was issued by the Ministry of Environmental Protection. The National 6 standard for motor vehicle pollutant emissions was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine.

How is speeding determined?

Determination of speeding is based on: Motor vehicles driving on the road must not exceed the speed indicated by speed limit signs or markings. On roads without speed limit signs or markings, motor vehicles must not exceed the following maximum driving speeds. Relevant information about speed limits is as follows: Introduction to speed limits: Speed limits typically refer to the regulation of driving speeds within a certain numerical range over a specified length of road. Purpose of speed limits: The main purpose is to pre-warn drivers to reasonably control their speed in subsequent sections of the road ahead, prevent the dangers of speeding, and ensure driving safety. Speed limits are an indispensable and most important part of road transportation safety.

What to Do If Too Much Antifreeze Is Added?

If too much antifreeze is added, you can directly use a syringe to extract the excess antifreeze or use absorbent paper towels to soak it up until the liquid level is below the maximum mark (MAX). Method for Replacing Antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. The five-way hose is named for its five connection points to various parts, as antifreeze flows through it and is distributed to different sections of the car to function. If there is any antifreeze leakage in this area, replace the hose or re-secure the connections as needed. Drain the old antifreeze, then flush the fluid channels with clean water. Add clean water to the antifreeze reservoir, then continue filling the reservoir to allow water to flow continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir may appear slightly pinkish. Continue adding clean water until the outflow is clear. Note: Remember to disconnect the heater hose and drain the water from the heater core. After draining for about an hour, add the new antifreeze through the radiator hose—this allows the antifreeze to flow quickly into the radiator. Then, add another bottle of antifreeze to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As the cooling system expels some air, the liquid level will drop. Top up the antifreeze to the "MAX" mark on the reservoir.

Is ETC Required for Free Holiday Travel?

During highway toll-free periods, vehicles entering through ETC lanes and exiting through ETC lanes will not be charged. Similarly, vehicles entering through manual lanes and exiting through manual lanes will also not be charged. However, if a vehicle enters through a manual lane and attempts to exit through an ETC lane, the exit barrier will not lift due to the absence of entry vehicle information, preventing normal exit. In such cases, the vehicle must exit through a manual lane. The toll-free period is determined by the time the vehicle leaves the highway exit toll lane. For regular roads, it is based on the time the vehicle passes through the toll station lane. In other words, entering the highway during toll hours and exiting during free hours will not incur charges. Conversely, entering during free hours and exiting during toll hours will result in charges. ETC Usage Notes: The ETC transaction sensing range is 8 meters. When the vehicle in front stops, maintain a distance of over 10 meters to prevent accidental payment for the preceding vehicle, which might have a faulty or no ETC device. The ETC lane recognition speed is 20km/h. Exceeding this speed may prevent reading vehicle device information, leading to failed transactions. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag becomes loose or detached, will render the tag ineffective. It can be taken to the bank where the ETC card was issued or a highway service center for inspection. Non-deliberate detachment or loosening only requires reactivation. When using a debit card linked to ETC, insufficient balance may cause transaction failure. Follow on-site staff guidance to use manual MTC lanes with cash or card payment. Excessively thick car windshields may cause poor signal reception. This is particularly relevant for vehicles that have had windshields replaced after accidents or those with modified front windshields.

How is the car body considered to have swept the line in reverse parking?

Body sweeping the line means the car body crosses the line, which results in a 100-point deduction and failure of the current test. Other actions that also incur a 100-point deduction include the vehicle crossing the line, not entering the parking space completely, stopping midway, not following the prescribed route or sequence, and exceeding the time limit. The total score for the two subjects is 100 points, with evaluation criteria set for failure, 20-point deduction, 10-point deduction, and 5-point deduction. The rules for the second subject of the motor vehicle driving license test state that any mid-test stop, rolling back, or not following the voice prompts will result in failure. Additionally, the wheels or body touching the line will also lead to failure. Many learners encounter line-touching issues during the second subject study, with 'touching the line' being the most common mistake leading to failure. The primary reason for wheel line-touching is the learner's failure to master the correct timing for steering. Besides missing the right moment to steer, another reason could be the steering speed not keeping up with the vehicle speed. Second subject deduction standards: Not wearing a seatbelt: 100-point deduction. Starting the engine without the gear in neutral: 100-point deduction. Not using the turn signal (including starting, changing lanes, overtaking, turning, and parking); using the turn signal for less than three seconds (this is easily overlooked!); forgetting to turn off the turn signal or using it incorrectly: 10-point deduction. Stalling once: 10-point deduction. Reverse parking: Not following the prescribed route sequence: 100-point deduction. Body crossing the line: 100-point deduction. Not completing the parking: 100-point deduction. Before reversing, if both front wheels do not pass the control line: 100-point deduction. Exceeding the 210-second time limit: 100-point deduction. Stopping for more than 2 seconds: 5-point deduction each time. Slope fixed-point parking and starting: After stopping, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: 100-point deduction. If not aligned but within 50 cm: 10-point deduction. Exceeding 30 seconds to start after stopping: 100-point deduction. Wheels touching the road edge line while driving: 100-point deduction. Rolling back more than 30 cm when starting: 100-point deduction. After stopping, if the body is more than 50 cm from the road edge line: 100-point deduction. Not tightening the parking brake after stopping: 10-point deduction per time. If the body is more than 30 cm but within 50 cm from the road edge line: 10-point deduction per time. Rolling back more than 10 cm but less than 30 cm when starting: 5-point deduction per time. Parallel parking: After parking, if the body crosses the line: 100-point deduction. Not using or incorrectly using the turn signal when parking: 10-point deduction. Exceeding the 90-second time limit: 100-point deduction. Touching the parking space edge line while driving: 10-point deduction per time. Wheels touching the lane edge line while driving: 10-point deduction per time. Stopping for more than 2 seconds: 5-point deduction per time. 90-degree turn: Wheels touching the road edge line: 100-point deduction. Not using or incorrectly using the turn signal during the turn, or not turning it off after the turn: 10-point deduction. Stopping for more than 2 seconds: 5-point deduction per time. Curve driving: Wheels touching the road edge line: 100-point deduction. Stopping for more than 2 seconds: 100-point deduction. Not driving in second gear or above: 5-point deduction.
