Can a pre-selected license plate number be canceled?

Pre-selected license plate numbers can be canceled. Within the 15-day validity period of the license plate, bring the required vehicle documentation to the local DMV to re-select and register a new plate number. After this period, the selection will be automatically considered abandoned. After successfully selecting a number through the 12123 traffic management platform, the license plate number is reserved for 15 working days starting from the next day. During this period, users are not allowed to re-select a number or modify submitted information online. If registration is not completed within the deadline, the pre-selected license plate number will be canceled, and the user will be blacklisted, prohibiting them from online license plate selection services for two years. On-site license plate selection process at the DMV: Prepare all necessary materials for license plate selection; Bring the documents to the vehicle inspection area and queue for inspection; After inspection, proceed with the selection process, which includes random selection or custom selection. Random selection involves choosing a satisfactory number from a list of options provided by the selection machine; Custom selection allows users to create their desired license plate number. However, due to the high volume of new vehicle registrations, most desirable numbers have already been taken, making the success rate of custom selection very low. Once the selection is completed, proceed to the service counter in the main hall to finalize other necessary procedures.

How to Distinguish the Authenticity of a Driver's License?

Methods to distinguish the authenticity of a driver's license: 1. Check the anti-counterfeiting mark: There is a significant difference between the anti-counterfeiting marks of genuine and fake driver's licenses. The anti-counterfeiting mark on a genuine license features the word "China" in a dot matrix pattern, composed entirely of dots and appearing blurry; whereas a fake license uses vector graphics with block-like strokes that appear clearer. 2. Examine the font: Check if the handwriting, color, and material on the main and secondary pages of the license are consistent. Inconsistencies indicate a fake license. Besides the printed font, look for noticeable pinpricks in the text. Additionally, observe special fonts; the English translation below "People's Republic of China Motor Vehicle Driver's License" includes the word "CHINA," where the letter "A" uses a special font visible under a magnifying glass. 3. Inspect the laser anti-counterfeiting mark on the plastic seal: The upper right corner of the license displays the words "China," "CHINA," "Driver's License," and "DRIVING LICENSE," which are clearly visible when tilted under light. The lower right corner features a distinct five-pointed star, and the laser star must overlap the photo. 4. Check the secondary page: The patterns on the secondary page should align seamlessly with those on the main page. If they don't, the license is fake.

What to Do When All 12 Points of a C1 Driver's License Are Deducted?

C1 driver's license has all 12 points deducted, at this time you need to study and take a test to clear the points. The specific process is as follows: 1. When a C1 driver's license has 12 points deducted, the license will be suspended: At this time, you need to go to the traffic management department of the public security authority at the place where the motor vehicle driver's license was issued or where the driver's illegal behavior occurred to undergo a 7-day (8 hours per day) study of road traffic safety regulations. Of course, the total study hours generally need to be completed within 15 days. 2. Then take the subject one test: After passing the test (90 points), the points will be cleared and the driver's license will be reissued. For those who fail the test, they need to reschedule and take the test again until they pass. 3. The test content is determined based on the points deducted: For those who have more than 12 points but less than 24 points deducted within one scoring cycle (one year), they need to take the subject one test; for those who have 24 points deducted, in addition to taking subject one, they also need to pass the subject three test to retrieve their driver's license.

What grade of gasoline should the new Highlander use?

The new Highlander should use 95-octane gasoline, as this is the recommended grade specified in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it marked on the fuel tank cap of the new Highlander. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower-octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the new Highlander occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, using a higher grade will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, with the actual experience being poorer performance. For vehicles recommended to use higher-octane gasoline, using a lower grade can cause engine knocking. Because the octane number is too low, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will be generated during the upward stroke. This resistance makes the engine run very unstable. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Can Tree Sap Corrode Car Paint?

Tree sap can damage car paint. Here is some relevant information about tree sap: 1. Introduction: Tree sap contains acidity. Any acidic or alkaline liquid can cause damage to car paint. The film-forming substance in car paint is usually polyurethane. Strong acids and alkalis corrode paint by reacting with the resin or pigment fillers in the paint, causing it to deteriorate. Initially, the paint will lose its luster, then gradually corrode, and in severe cases, it may even corrode the car's body. 2. Precautions: Not only tree sap, but also bird droppings and air conditioning condensation can damage car paint.
