Generally speaking, ordinary spark plugs need to be replaced every 20,000 kilometers, while platinum or iridium spark plugs can last up to 60,000 kilometers or even longer before replacement. Spark plugs: Spark plugs are crucial components of the ignition system in gasoline engines. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Corolla: The Corolla, formerly translated as "Huaguan," is a brand under Toyota Motor. The Corolla is equipped with Michelin 215/45R17 tires, high-performance shock absorbers, TRD-TF4 17-inch sport rims, reinforced clutches, and high-performance brake pads, ensuring it has relatively ideal sports performance.

Is Running a Yellow Light Considered Running a Red Light?

Running a yellow light and running a red light are both considered the same traffic violation—driving a motor vehicle in violation of traffic signal regulations. According to the "Road Traffic Safety Law of the People's Republic of China," this offense is punishable by a fine and a deduction of 6 points from the driver's license. Article 26 of the "Road Traffic Safety Law of the People's Republic of China" states: Traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning. The "Road Traffic Safety Law" stipulates: A yellow light serves as a warning, and motor vehicles should slow down when approaching an intersection. If a vehicle has already crossed the stop line when the yellow light turns on, it may continue to pass; otherwise, it should stop. The "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China," Article 38, specifies the meanings of motor vehicle and non-motor vehicle signals: When the green light is on, vehicles are permitted to proceed, 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 proceed. When the red light is on, vehicles are prohibited from proceeding. 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 proceed if they do not obstruct the passage of other vehicles or pedestrians. Electronic traffic enforcement captures red-light violations based on the following three photos, which are reviewed by traffic police to determine whether a red light was run: An image of the vehicle not having passed the stop line when the red light is on. An image of the vehicle's front wheels pressing against the stop line. An image of the vehicle's entire body having crossed the stop line. If these three photos show that the vehicle moved beyond the stop line while the red light was on, the traffic police can confirm a red-light violation during review. To avoid running a yellow light: Slow down when approaching an intersection, maintain a speed of 20–30 km/h, keep a safe distance from the vehicle ahead, and avoid tailgating or rushing through a yellow light. Alternatively, pay attention to the traffic signal in advance; observe the duration of the green light—if traffic is light and the green light lasts longer, prepare to slow down.

Does idling with the heater on harm the car?

Idling with the heater on will slow down the engine's warming-up speed and increase fuel consumption, but it won't cause damage to the car. More information about idling is as follows: 1. According to relevant test data, using the heater while idling is related to the car's displacement and engine tuning. Of course, the main impacts of prolonged idling are increased fuel consumption and engine carbon buildup, so it's recommended not to leave the car idling for extended periods. 2. In idle mode, turning on the heater won't cause serious harm to the car, but it does affect passengers. However, since fuel doesn't burn completely during idling, carbon monoxide is produced. If windows remain closed, carbon monoxide concentration inside the cabin will gradually accumulate, potentially leading to carbon monoxide poisoning for occupants.

How many points are deducted for cutting in line while waiting in traffic?

Cutting in line while waiting in traffic results in a deduction of two points. According to the "Decision of the Ministry of Public Security on Amending Traffic Regulations" implemented from April 1, 2016, when encountering a situation where vehicles ahead are stopped or moving slowly, drivers who borrow lanes to overtake, occupy the opposite lane, or cut in line will be penalized with a deduction of 2 points. Below is an extended explanation: Traffic congestion at intersections due to non-sequential waiting: When traffic is blocked at an intersection due to obstruction, vehicles from behind may change lanes randomly, cut in line, or squeeze into the normal queue to pass early, leading to further obstruction and saturation of traffic flow at the intersection.

Why does pearl white touch-up paint turn yellow after one month?

The reasons why pearl white touch-up paint turns yellow after one month are as follows: Issues with the paint itself: On one hand, there may be inherent problems with the paint. If this is the case, you can go back to the place where the touch-up was done and request a repaint, and even seek compensation if necessary. Poor touch-up technique: On the other hand, it could be due to improper operation by the technician during the touch-up process. This might involve spraying the pearl layer before the white base coat has dried, or applying the clear coat before the pearl layer is properly set. In such cases, you can only seek after-sales service from the paint shop. Maintenance: If color differences appear, polishing can help restore the car's original color. Regular car paint maintenance is also important—avoid prolonged exposure to sunlight and rain, and park the car in a garage if possible to slow down the yellowing process.

Can a ride-hailing driver's license be transferred to another location?

Ride-hailing driver's licenses can be transferred to another location. According to the "Notice on Further Strengthening the Management of Road Transport Practitioners' Qualification Certificates" issued by the Ministry of Transport, if one year has passed since the initial issuance of the qualification certificate, the holder can apply to the original issuing authority for the transfer of their professional qualification management records. The transferred records must be handed over to the management department of the new location within 30 days after the transfer procedures are completed. Here is an extended introduction: Ride-hailing driver's license application in a different location: The ride-hailing driver's license can be applied for in a different location, but the applicant must hold a C1 or C2 driver's license. Since driver's licenses are valid nationwide, when applying for a ride-hailing license in a different location, the vehicle used cannot be from that different location—it must be a local vehicle that meets the local entry requirements. As long as the vehicle meets the entry requirements, an out-of-town driver's license can be used to apply for the ride-hailing license.
