How to File an Insurance Claim or Repair the Car Yourself After a Scratch?

There are two scenarios after a car scratches itself, as detailed below: 1. If the vehicle is covered by commercial insurance, specifically the vehicle damage insurance, the owner can directly report the incident to the insurance company for vehicle handling. 2. If the vehicle is not covered by commercial insurance, the owner must repair the scratch themselves and cannot file an insurance claim. Below is an additional introduction to the process for car owners to claim compensation from the insurance company: 1. The car owner should report the incident to the insurance company within 48 hours, and the insurance company will dispatch a specialized loss assessor to evaluate the damage. 2. If more than 48 hours have passed, the car owner is advised to bring their original ID card to the insurance company to report the incident. 3. If the insurance company's loss assessor asks whether the scratch was self-inflicted, the car owner can answer truthfully, as this will not affect the compensation amount from the insurance company.

Does the Dash Cam Still Work After Locking the Car?

After the engine is turned off, the dash cam continues to work if it has a parking monitoring (motion detection) function. The parking monitoring function requires the dash cam to have a built-in battery or to be connected to the ACC fuse for power supply. Once the vehicle is turned off, it automatically enters parking monitoring mode, where the sensors continuously monitor the vehicle's condition. If any abnormality or vibration is detected, the dash cam automatically records the monitoring video and saves it separately. Here is some additional information: The first way a dash cam operates is by drawing power from the cigarette lighter, but the cigarette lighter must remain powered after the vehicle is turned off. The second method is for the dash cam to draw power from the reading light or other constant power sources. Both methods allow the dash cam to continue working after the vehicle is turned off, essentially operating 24/7. However, both methods have a drawback: the continuous power draw from the dash cam can drain the battery, making it unable to provide sufficient power the next time the engine is started.

Can I Take the Driving Test (Subject 3) Without My ID Card?

You cannot take the Subject 3 driving test without your ID card. Here are the relevant details: 1. According to the Ministry of Public Security's Order No. 91 and related regulations, candidates must present a valid personal identification document—either a resident ID card or a temporary resident ID card—to take the driving test. Typically, before entering the examination venue for Subject 3, candidates are required to verify their original ID card. For those taking the test in a different location, the original residence permit must also be verified. Both documents are mandatory. 2. If your ID card is lost before the Subject 3 test, you should promptly apply for a temporary ID card at the local police station. A temporary ID card holds the same legal validity as a regular ID card within its effective period and can be used to take the Subject 3 test.
