Reasons for car shaking at idle: 1. Unstable oil pressure, abnormal fuel pump supply pressure, or incorrect readings and poor performance of the intake pressure sensor can cause body shaking; 2. Severe engine carbon buildup, dirty throttle body, or excessive carbon deposits in the fuel injectors; 3. Ignition system issues, poor ignition system performance, or faulty spark plug firing can also lead to such symptoms; 4. Aging engine components, engine mounts are responsible for absorbing minor vibrations during engine operation. If the engine mounts fail, these vibrations will be transmitted to the steering wheel and cabin, causing shaking at idle.

Does running a yellow light that turns red midway count as running a red light?

Whether running a yellow light that turns red midway counts as running a red light depends on whether the rear of the vehicle has crossed the line when the red light turns on. If the vehicle has just crossed the line and the driver does not continue moving the vehicle, maintaining the status quo, the traffic authorities will not consider it as running the light. More details are as follows: There is a three-second transition period between the yellow light turning on and the red light turning on. Electronic police operate 24/7, and they do not capture images when the yellow light is on—they only start capturing images when the red light turns on. If you accidentally run a red light but have already passed the stop line without completely crossing the intersection, traffic police may cancel the violation based on the following conditions: if stopping at the intersection does not obstruct traffic; if it does not affect pedestrians crossing the crosswalk; or if the vehicle has not completely passed through the intersection. As long as these three conditions are met, stopping after running the red light will not result in a fine.

Can I drive without the supplementary card of the vehicle license?

Driving without the supplementary card of the vehicle license is not allowed. According to the Traffic Safety Law, driving without the supplementary card of the vehicle license is considered a violation. Here are the relevant details: 1. Composition of the vehicle license: A complete driver's license includes the original and the supplementary card, and a complete vehicle license also includes the original and the supplementary card. If the supplementary card is missing, it means the driver's license or vehicle license is incomplete, and you will be penalized. If both the driver's license and vehicle license supplementary cards are lost, it is recommended to go to the local transportation management office and traffic police detachment to reapply for them. Otherwise, you cannot drive on the road. 2. Handling method: The correct way to handle the situation of not carrying the vehicle license is to temporarily detain the motor vehicle, issue a compulsory measure certificate until the relevant proof materials (vehicle license) are presented, and then make an administrative penalty decision. The traffic police cannot make an administrative penalty decision on the spot and can only temporarily detain the motor vehicle.
