Why is the electronic driver's license not displaying?

It may be due to the DMV information not being uploaded. Here are the relevant details: Electronic Driver's License: Commonly known as the 'e-license,' the electronic driver's license was piloted in three cities—Tianjin, Chengdu, and Suzhou—starting June 1, 2021, to provide drivers with online 'license display' and 'code display' services, facilitating easier travel and transactions for the public. It will be fully promoted nationwide in 2022. Applicability: Currently, the electronic driver's license is only applicable within the local city and not in areas outside the city, including highways, as highways fall under separate jurisdiction and are not managed by local traffic authorities. Therefore, it is still necessary to carry the paper version of the driver's license for unexpected situations. Traffic Management 12123: On the Traffic Management 12123 app, click on the 'Driver's License' option in the top left corner of the homepage. On the driver's license interface, you can see the electronic driver's license, completing the process of opening it. The electronic vehicle license is a digital version of the vehicle license, serving as a supplement to the physical document. In cases where the physical document is not carried, the electronic version can be used for roadside checks and other purposes.

The nameplate is located in different positions on the car, usually under the front passenger door—just open the door to see it. 2. Look for the vehicle's factory certificate, but generally, this certificate is kept at the vehicle management office. 3. Review your car purchase contract, which usually specifies the model purchased.

What Causes the Hissing Sound When Braking?

The reasons for hearing a hissing sound when braking are as follows: 1. When you press the brake pedal, you can clearly hear a leaking sound, and sometimes a hissing sound after pressing the pedal. In this case, the initial judgment is that there might be an issue with the brake booster. 2. The leaking sound generally falls into two scenarios: one occurs during the normal operation of the brake booster but is only brief; the other happens after pressing the pedal, with a more noticeable or continuous sound. Additional Information: 1. To check if the sound is caused by a leaking brake booster: Start the engine, let it run for 1~2 minutes, then turn it off, and press the pedal three times. For a normally functioning vacuum booster, the first press will have a normal pedal travel due to sufficient vacuum in the booster; the second press will show significantly reduced travel as some vacuum has been lost; by the third press, with very little vacuum left in the booster, the pedal travel will be minimal, and further pressing will be difficult. 2. This is the so-called "each press higher than the last." It proves the booster is not leaking and is functioning properly. If each pedal press has minimal and unchanged travel, known as "extremely hard pedal," it indicates the booster is leaking and failing. Severe leaks can produce audible sounds, and a leaking booster should be replaced.

Is it allowed to drive in the wrong direction on a service road?

Driving in the wrong direction on a service road is not allowed. According to the "Road Traffic Safety Law of the People's Republic of China", vehicles must drive on the right side of the road. Driving in the wrong direction will result in a fine and a deduction of 3 points from the driver's license. On roads with solid dividing lines, vehicles are prohibited from entering the opposite lane. Specifically, roads with double solid lines or single solid lines as dividing lines must not be crossed under any circumstances. Below are some driving precautions: 1. Check the rearview mirrors: When turning or changing lanes, always use the turn signals and slow down. Before turning, always check the rearview mirrors. For left turns, primarily check the left rearview mirror; for right turns, primarily check the right rearview mirror. For both left and right turns, also check the interior rearview mirror. 2. Do not focus solely on the area directly in front of the vehicle: When driving on clear roads, look straight ahead at a distance of about 100 meters, avoiding fixation on the immediate area in front of the vehicle. 3. Depress the clutch: Generally, when decelerating at speeds above 40 km/h, there is no need to depress the clutch immediately. Wait until the speed drops to around 20 km/h before depressing the clutch. 4. Steering: When turning at high speeds, steer slowly; when turning at low speeds, steer quickly.
