What should be noted when driving a motor vehicle through school zones?

When driving through school zones, the following key points should be noted: Honking is prohibited in school zones, and reminder signs are usually posted – drivers must comply. Motor vehicles should slow down promptly when passing through school areas, where the speed limit is generally no more than 30 km/h. While passing, drivers must observe road conditions on both sides and remain vigilant to avoid hazards caused by students crossing the road. Motor vehicles must adhere not only to specific driving regulations in school zones but also to clear rules when passing through residential areas, mountain curves, and other locations. Drivers should exercise caution to ensure road safety. Below are the driving regulations: When traffic signs or road markings indicate priority, yield to the party with the right of way. In the absence of traffic signs or markings, stop and look before entering an intersection, yielding to vehicles approaching from the right. Turning vehicles must yield to straight-moving motor vehicles. Right-turning vehicles from opposite directions should yield to left-turning vehicles.

What does it mean when the heater is turned on with A/C?

Turning on the heater with A/C means the car's compressor is running, which will additionally increase the vehicle's fuel consumption. Reasons why turning on the heater with A/C increases fuel consumption: In A/C mode, since the car's air conditioning compressor is always in operation, it will inevitably lead to increased fuel consumption and additional engine load. When using the heater, the A/C switch should be turned off to prevent the compressor from running and causing extra fuel consumption during heating. Function of A/C: A/C is the abbreviation for air conditioning, with its full name being air condition, which can be understood as air control or air adjustment. It achieves the purpose of cooling or heating through different operation modes of the air conditioning compressor, hence it has dual meanings of cooling and heating. However, in cars, since the heating function of the vehicle's air conditioning is accomplished through the heat from the engine's cooling water and the heating wires on the glass, A/C only has the single meaning of cooling in this context.

How many days do I have to register my vehicle after successfully selecting a license plate number on the 12123 traffic management platform?

After confirming the license plate number selection on the 12123 traffic management mobile app, you must complete the vehicle registration process within 3 days. Otherwise, the selected plate number will be returned to the pool, and the vehicle owner will be prohibited from using the online platform for license plate selection for one year. This is because the national license plate selection system has eliminated all third-party selection methods. Currently, you can only choose between the in-person 50-option random selection at the window or pre-selecting a plate number on the 12123 internet platform. The online pre-selection offers both custom-composed and random selection methods. If you wish to create a personalized or meaningful license plate number, 12123 is your only option. In China, license plates serve as unique identifiers for vehicles. The primary function is to identify the province, city, or county where the vehicle is registered. Traffic management departments can trace vehicle owners through their license plate numbers.

How to Shift Gears in the Subject 3 Road Test?

Here are the methods for shifting gears in the Subject 3 road test: press the clutch, shift to 1st gear, and after starting, you can shift to 2nd gear. When the speed reaches 20, you can shift to 3rd gear, and when the speed reaches 30, you can shift to 4th gear. Below are the precautions for shifting gears in the Subject 3 test: 1. Master the clutch pedal: Practice pressing the clutch pedal frequently to maintain a stable state and develop a good habit—press it all the way down and release it slowly. 2. Coordinate the throttle and clutch properly: Ensure proper coordination between the throttle and clutch. When starting, shift to 1st gear, release the clutch slowly, and apply the throttle at the semi-clutch state. Only release the clutch completely after the car starts moving. 3. Grasp the timing for shifting gears: Shift gears when the engine speed is around 2000 RPM. First, reduce the throttle and then press the clutch to prevent the clutch from being forced to disengage. Then, shift gears. The shifting sequence must be 1st gear → 2nd gear → 3rd gear → 4th gear → 5th gear. Skipping gears is not recommended. The downshifting sequence depends on the speed and the specific condition of your car. Generally, downshift when the engine speed is below around 1500 RPM. 4. Shift gears frequently: Shift gears frequently during driving based on the speed and road conditions. Choosing the appropriate gear is essential. Infrequent shifting can easily cause the car to drag, increasing wear and fuel consumption. Therefore, it is crucial to develop the habit of frequent shifting. 5. Make shifting movements smooth: Ensure that shifting movements are smooth, and the clutch is pressed all the way down in one motion. Gear shifting should also be done in one step. Familiarize yourself with the gear positions and practice the feel frequently.
