Access the Traffic Management 12123 platform page. The identity verification number is your ID card number. If you forget your password, you can reset it by verifying your mobile phone number and then log in again. Verify the previously registered fingerprint on your phone. The vehicle status will be displayed. Here, you can view the complete vehicle information under your name.

After selling my car, I was also curious if I could still see it on the Traffic Management 12123 app, but experience tells me this app is mainly linked to the current owner. If the vehicle information disappears from your account after the sale, it means the transfer process is complete; otherwise, if it's still bound, you need to confirm the procedures at the vehicle management office to avoid lingering issues. Before selling the car, the buyer and I went through the transfer process together, and the app automatically updated the information, which was convenient. However, after the sale, you can no longer check for violations or the vehicle's status, so the focus should be on retaining the transfer certificate. Although the app has many functions, it doesn't guarantee real-time updates, especially after the new owner takes over. It's best to periodically manually check the binding interface—safety first, don't let small issues turn into big troubles.

I often use the vehicle management app to handle car-related matters. Operating the Traffic Management 12123 app is quite simple: after logging in, click on the personal center to view the list of bound vehicles. If the car disappears from the list after selling it, it means the transfer was successful; otherwise, urgent action is needed to unbind it. The app is designed to sync owner data in real-time, but selling a car means the ownership has been transferred, so you can no longer check its details like violation records. During the transfer process, carefully assist the buyer in completing the procedures. Remember, the app is just a tool—don’t rely on it entirely. Other daily functions like violation queries remain usable, but once the car is gone, there’s no point dwelling on old data.

When my husband and I sold our car, we couldn't see the old vehicle information in the app anymore. The Traffic Management 12123 system only links to the current owner's account, and it automatically removes the vehicle binding after sale. You can open the app to check the personal vehicle section for confirmation - if the list is empty, you can rest assured. If there are any residual records, visit the vehicle management office as soon as possible to complete the deregistration. When selling a car, always complete the transfer procedures together with the buyer and keep the documents for future reference. The app can still check your personal driver's license, but the vehicle status is now managed by the new owner - don't overlook these small details.

What is the speed limit for passenger cars on highways?

On highways, the maximum speed for small passenger cars must not exceed 120 kilometers per hour, while other motor vehicles must not exceed 100 kilometers per hour, and motorcycles must not exceed 80 kilometers per hour. Relevant details are as follows: 1. Regulations: On highways with two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; on highways with three or more lanes in the same direction, the minimum speed for the far-left lane is 110 kilometers per hour, and the middle lane's minimum speed is 90 kilometers per hour. If the speed limit indicated by road signs differs from these lane speed regulations, drivers must follow the speed limit indicated by the road signs. 2. Real-time monitoring: To effectively enforce highway speed limits, public security traffic authorities have installed GPS satellite positioning systems on medium and large passenger vehicles for real-time tracking and monitoring. Other vehicles are subject to random checks at exits to control and prevent speeding violations.

Do I Need to Replace Two Tires at the Same Time?

It is not necessary to replace two tires at the same time. The specific situations can be divided into the following: 1. If it is a new car and the mileage is not high, you only need to replace the problematic tire because the wear difference between tires on the same axle is not significant; 2. If the vehicle has already traveled tens of thousands of kilometers but does not yet require tire replacement, and only one tire has an issue, replacing just one tire may cause uneven height, leading to vehicle bumpiness or steering deviation at higher speeds. In this case, it is best to replace a pair of tires; 3. If the repair shop does not have the same brand or model of tire for the vehicle, replacing a pair is necessary for short-term driving, while replacing two pairs is required for long-term driving.

Should You Shift to Neutral or Engage the Handbrake First After Parking?

After parking, you should engage the handbrake first before shifting to neutral. Below is the correct parking sequence: 1. Pull over: Stop the vehicle by the roadside, shift the transmission into neutral, and then engage the handbrake. Shifting to neutral prevents accidental throttle input. Once in neutral, even if the accelerator pedal is pressed, the vehicle won't surge forward. 2. Turn off the engine: Depress the clutch, shift into 1st gear, and then exit the vehicle. This step is actually a precaution against forgetting to engage the handbrake. 3. Prevent accidents: If the gear is left in neutral and the driver forgets to engage the handbrake, the vehicle may roll, leading to safety hazards. After shifting into 1st gear, even if the handbrake is forgotten, the vehicle generally won't roll on its own. This is an added safety measure.

Will Pea-Sized Hail Damage a Car?

Pea-sized hail has minimal impact on cars and generally does not cause damage. Vehicles possess a certain level of impact resistance, and in most cases, they remain unharmed unless the car body or glass is of poor quality. Below are some measures to take when encountering hail while driving: 1. Seek Shelter: Try to move the car to a covered area, preferably an underground parking lot. If the car is parked outdoors, covering it with a thick blanket can help minimize potential damage. 2. Avoid Personal Injury: If there is no place to take shelter when hail strikes, quickly move to the rear seats of the car to avoid injury from shattered windshield glass. Additionally, hail damage falls under the coverage of a comprehensive auto insurance policy. Car owners who have purchased such coverage can file a claim with their insurance company if their vehicle is damaged by hail.
