Is there a time limit for retaking the subject one test after deducting 12 points?

There is a time limit for retaking the subject one test after deducting 12 points. If a driver's license is deducted 12 points, the license will be confiscated. To retake the test and retrieve the driver's license, the driver must attend a 7-day study session on road traffic safety laws, regulations, and related knowledge at the traffic management department within 15 days. Within 20 days after completing the study session, the driver must take the subject one test. Only after passing the test can the points be cleared and the driver's license returned. If the driver fails to attend the study session at the designated place within the specified time, it is best to consult the traffic management department to explain the reason for not participating in the study session and then apply to take the test to retrieve the driver's license. Subject one test content: Basic knowledge of motor vehicles; laws, regulations, and road traffic signals; basic knowledge of safe driving and civilized driving; basic knowledge related to motor vehicle driving operations. Test process: Follow the staff's instructions and collect your driving school file in order in the waiting area; Carry and present your ID card for inspection by the supervising officer; Mobile phones must be turned off when entering the test area; No loud noise is allowed in the test area; Regulation textbooks are not allowed in the test area (or must be placed in a bag); After the test, keep your ID card safe and submit the file to the "Submission Window" at the front of the test area; Candidates who pass the test will sign under the guidance of the staff at the exit of the test area and then leave; Candidates who fail the test can leave the test area and wait for the driving school staff to notify them of the retake time.

Will Not Going to the 4S Store After the First Maintenance Affect the Warranty?

Not going to the 4S store after the first maintenance will not affect the warranty. Specific explanation: If the car is under warranty and has not been repaired or maintained at a 4S store, the car will not lose its warranty opportunity. In other words, after the first maintenance, if you go to an external repair shop for maintenance, the car can still enjoy the warranty provided by the 4S store. If you always maintain the car at a 4S store, some warranty processes are relatively simple and do not require too many other operations. However, maintenance at an external repair shop will be relatively more complicated. Related knowledge about car warranty: If some minor parts or parts unrelated to where the maintenance is performed have problems, as long as it is confirmed that the damage was not caused by maintenance at the repair shop, there is no doubt that the 4S store will definitely provide the warranty. This is because these parts have nothing to do with where or when the maintenance is performed, so the 4S store naturally has no reason to refuse.

What Causes a Battery to Bulge?

Battery bulging occurs when the battery enters a thermal runaway state during charging. Detailed Explanation: Thermal runaway happens due to excessive charging or when the battery, after prolonged use, experiences severe water loss and sulfation, leading to increased internal resistance. The increased internal resistance causes the battery temperature to rise during charging under the influence of current. The rising temperature further increases the current, creating a vicious cycle that eventually causes the battery to deform and bulge. How to Handle a Bulging Battery: Once a battery is confirmed to be bulging, it should be replaced as soon as possible. Before replacement, it is essential to have a professional repair facility inspect and measure the vehicle's charging system and battery connections to ensure normal charging conditions and that the battery itself is not at risk of bulging due to external factors.
