Is the QR Code on the Electronic Driver's License Only Accessible by Traffic Police?

Electronic driver's license QR codes can only be scanned by traffic police. When traffic police use handheld law enforcement devices to scan the QR code, they can access all information related to the driver's license holder. Introduction to Electronic Driver's License: The electronic driver's license, commonly known as the "e-license," was piloted in three cities—Tianjin, Chengdu, and Suzhou—starting from June 1, 2021, to digitize motor vehicle driver's licenses. It provides drivers with online "license display" and "code display" services, offering greater convenience for public affairs and travel. It will be fully promoted nationwide in 2022. How to Handle Traffic Violations with an Electronic Driver's License: Open the Traffic Management 12123 app, click on the electronic driver's license, and display your electronic driver's license to the processing personnel to handle traffic violations.

Why is the car not responding when starting?

Possible reasons for the car not responding when starting are as follows: Engine malfunction: Related to issues such as poor performance of the main fuel injector, cold start injector, temperature control switch, ECU and control circuit, weak battery, damaged ignition or pulse generator, fuel system not supplying fuel or supplying fuel abnormally, etc. Automatic transmission malfunction: Slow acceleration, strong impact during automatic gear shifting, high oil temperature, lack of high-speed gear, inability to start, inability to shift the gear lever, etc. Most automatic transmission faults are caused by untimely maintenance and adjustment, apart from component failures due to long-term use.

What are the reasons why motor vehicles are prone to skidding inside tunnels?

The reason why motor vehicles are prone to skidding inside tunnels is that the tunnel floor is relatively slippery. Precautions for driving in tunnels: It is necessary to appropriately reduce speed before entering the tunnel. Tunnel entrances usually have clear speed limit signs to remind drivers to slow down before entering. The lanes inside the tunnel are typically narrower than those outside, so reducing speed helps drivers accurately assess road conditions. At the same time, it is essential to turn on the low beam headlights. Due to the relatively dim lighting inside the tunnel, drivers may experience temporary "blindness," making it necessary to use low beam headlights to clearly see the road ahead. It is important to note that using high beam headlights inside the tunnel is strictly prohibited, as it is an extremely dangerous action. Requirements for driving in highway tunnels: Changing lanes or overtaking is prohibited inside tunnels. Due to the limited space and poor lighting conditions, lane changes and overtaking can easily disrupt the normal flow of other vehicles. Additionally, most tunnels are now equipped with comprehensive camera surveillance systems, and illegal lane changes will result in a 3-point penalty and a fine.

How Long Can You Listen to Music After the Car Is Turned Off?

After the car is turned off, a 35Ah battery can play music for about 3 hours, while a 45Ah battery can last between 3 to 4 hours. Battery Capacity: The current battery capacity SOC (State of Charge) of the vehicle is equal to the remaining charge/usable capacity × 100%; however, these two values are generally measured indirectly through the ampere-hour integration method, which still has many errors. Moreover, as the battery degrades, these errors become increasingly significant. Power Battery: For power batteries, the discharge capability varies under different temperatures. For example, the usable capacity refers to the maximum charge (AH) that the battery can store in its current state. This value changes constantly, with the most obvious factor being aging. Over time, as the number of charge-discharge cycles increases, the usable capacity gradually decreases.

Is It Advisable to Buy a Second-hand Car Without Transferring Ownership?

It is not advisable to buy a second-hand car without transferring ownership. If you only sign an agreement without transferring ownership when buying or selling a used car, the previous owner can still use the car as collateral, which may harm the interests of the subsequent owner. Definition of Ownership Transfer: Transferring ownership of a second-hand motorcycle, as the name implies, means changing the name of the vehicle's owner. It is an indispensable procedure in the process of buying and selling used vehicles. Not transferring ownership can cause inconvenience to both the buyer and the seller. Precautions for Ownership Transfer: According to Article 31 of the "Road Traffic Accident Handling Measures," if a motor vehicle driver is temporarily unable to compensate, the driver's employer or the owner of the motor vehicle is responsible for making the payment. If the ownership transfer is not completed, the owner remains the original owner, meaning that if someone else causes an accident, the original owner will be held liable. Moreover, if the property rights are not transferred to your name, disputes may easily arise in the future.

What are the reasons for a car not responding when starting?

Reasons for no response when starting are as follows: Battery depletion: Battery depletion does not mean the battery is completely dead, but the voltage is insufficient to start the car. In this case, you need to jump-start the car or replace the battery. Spark plug damage: Damaged spark plugs in the engine are one of the reasons why the car won't start, as the spark plugs are needed to ignite the gasoline in the cylinders to get the engine running. Distributor circuit failure: The main circuit for starting is the distributor. If the distributor is damaged, it may also cause the car to fail to start. Starter damage: The starter is primarily responsible for turning the engine during ignition. If the starter is damaged, the car won't start.
