To modify the registered mobile phone number for motor vehicle filing, the vehicle owner needs to bring their original ID card. For company vehicles, the original organization code certificate, company seal, and the agent's original ID card are required. The modification must be done at the internet service window of the vehicle management office. Below is relevant information regarding the modification of the registered mobile phone number for motor vehicles: 1. Pay attention to the registration time: Some vehicle owners may have registered their phone numbers a long time ago, and the phone numbers registered for their driver's license or vehicle may no longer be in use but have not been updated at the vehicle management office in time. Even if they want to change the information on the "12123" app, they cannot register successfully if the phone number used for registration is not the one previously registered. 2. Update the registered phone number promptly: If the phone number used for registering the driver's license or vehicle was used to register for the traffic management app "12123", the owner can log in directly and make changes on the business hall page of the app. Failing to update the registered phone number promptly can have consequences. If the driver's mobile phone number or other information changes and is not updated at the vehicle management office in time, they may not receive SMS reminders, leading to overdue renewal or inspection of the driver's license. Exceeding the time limit may result in point deductions, fines, or even revocation of the driver's license, causing inconvenience to daily life and travel.

After changing my phone number, I wanted to update my registration information and immediately went to the nearest DMV. I brought my ID card, driver's license, and vehicle registration certificate. The front desk asked me to fill out a "Motor Vehicle Change Registration Application Form," mainly to fill in the old and new phone numbers and my name. After the staff verified the information, the new number had to be verified on the spot via SMS to ensure it could receive messages. The process was simple, but waiting in line took some time—about half an hour to complete. After the change, I felt relieved knowing that traffic violation notices and annual inspection reminders would be sent directly to my new phone, so I wouldn’t miss messages on the old number. Since my phone number is linked to too many apps and records, I make sure to update it regularly to avoid being unreachable in emergencies. Don’t procrastinate—just bring all the required documents, and the process can be completed quickly.

Going directly to the vehicle management office is the fastest way. Just bring your original ID card and the vehicle's license. When I went, I filled out an application form indicating the new phone number to be changed. The staff entered the new number into the system, then sent a verification code to the new phone to confirm it was my own operation. The entire process took less than 20 minutes. It's essential to update your phone number promptly; otherwise, you won't receive notifications for traffic violations, leading to higher overdue fines, and you won't be able to log in to the vehicle management app. It's recommended to make an online appointment in advance to reduce waiting time. After the change, the vehicle management system will automatically update, and all related services will use the new number.

Updating your registered mobile number is crucial, as traffic violation notifications are sent directly to your phone. I brought my ID and vehicle documents to the DMV, filled out the form with both old and new numbers, and verified the new number on-site in one go. Failing to update it promptly may result in missed messages, causing issues that could affect your car insurance or annual inspection progress. It's advisable to regularly check if your mobile number matches to avoid risks.

How to Drain Engine Oil from a Car?

Drive the vehicle onto a steep slope, then turn off the engine and engage the handbrake. Because the fuel tank has a U-shaped bottom, it's difficult to drain oil on flat ground. Open the fuel tank and insert a plastic hose. Place the other end of the plastic hose into your mouth and suck hard, being careful not to get oil in your mouth. Once you see oil coming up, place that end of the hose into an oil container and let it drain naturally. This is the most traditional method for draining gasoline from a car, but it doesn't completely empty the tank. When you need to drain oil, you can visit a repair shop or 4S store to use professional equipment for the job.

How to Check the Results of Subject One Exam?

The score of the Subject One exam is available immediately. After completing the questions and clicking submit, the system calculates the candidate's score, and the result is displayed on the spot. However, if you want to check your score online, you will need to wait for the data to be synchronized to the system. You can check your Subject One score on the "Traffic Safety Comprehensive Service Management Platform," provided the data has been synchronized. Generally, it takes about 2-3 days for the exam results to be uploaded to the system after passing the exam. In some cases, synchronization may be completed within 1-2 hours, and an SMS notification will be sent to the candidate. The total duration of the Subject One exam is 45 minutes. The exam consists of 100 questions, including true/false and multiple-choice questions, with a full score of 100 and a passing score of 90.

How to Achieve Proper Meshing of a Pair of Gears?

The base pitch of a pair of gears must be equal. Because the cutting tools for involute gears are standardized, the meshing conditions for gears are that the pressure angles on the pitch circles of both gears are equal, the modules of both gears are equal, and they conform to the national standard values. The condition for continuous meshing of gears is that the contact ratio must be greater than 1. The meshing points of the working tooth profiles on one side of a pair of involute gears must simultaneously lie on the meshing line N1N2. If two pairs of teeth are engaged simultaneously, the meshing points of the working tooth profiles of both pairs must also lie on the meshing line. Standard gears are those whose parameters all conform to standard values, and standard gears for different purposes are manufactured according to different standards. Standard gears are often used as reference samples for producing gears or for calibrating measuring instruments. For a pair of meshing transmission gears, an installation where the pitch circle and the reference circle do not coincide is called a non-standard installation, and its center distance is referred to as the non-standard installation center distance. This results in backlash, impact, a decrease in the contact ratio, and reduced smoothness.

What Does the Triangle with Yellow Exclamation Mark Indicate?

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: Visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in vehicles. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark, a red circle with parentheses and an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic Transmission Fault: A yellow gear with an exclamation mark indicates an automatic transmission fault warning light, signaling a transmission issue or low transmission fluid. Transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, indicating either a brake system malfunction or low brake fluid. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: A bracket with a horizontal line and an exclamation mark in the middle indicates a tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is a lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
