Are Driving Licenses Universally Valid?

Driving licenses are valid nationwide, but the license review must be conducted at the place where the license was originally issued. For convenience, vehicle owners may also choose to replace their license. According to national regulations, if the household registration of a motor vehicle driver is relocated outside the jurisdiction of the original vehicle management office, the driver should apply for a license replacement at the vehicle management office of the new location. If a motor vehicle driver resides outside the jurisdiction of the vehicle management office where the license was issued, they may also apply for a license replacement at the vehicle management office of their current residence. License transfer can be categorized into two types: license transfer-out and transfer-in. This refers to the procedure where vehicle owners, due to reasons such as job transfers or moving, relocate from their original place and transfer their driving license to their new residence to avoid the hassle of annual license reviews. Whether transferring out or in, the vehicle management office of the final residence jurisdiction serves as the licensing authority. License transfers can be summarized as local residents transferring in with an out-of-town license and non-local residents transferring in with an out-of-town license.

Which Light to Observe When Making a Right Turn?

When facing a circular red traffic light, you can generally make a right turn even if the intersection displays a red light, unless there are specific traffic instructions prohibiting it. However, with arrow signal lights, you may only turn right when the right-turn arrow turns green; otherwise, it constitutes running a red light violation. Below are relevant details: When there is a dedicated right-turn signal light or right-turn sign, you must follow the signal's instruction. In the absence of a right-turn signal or sign, you can turn right when the straight-through light is red. At intersections without dedicated bicycle or pedestrian signals, non-motorized vehicles and pedestrians should follow the motor vehicle traffic signals. When the light is red, right-turning vehicles may proceed provided they do not obstruct the passage of other vehicles or pedestrians. Another often overlooked violation when making a right turn is failing to yield to pedestrians. If pedestrians are crossing the road during your right turn, you must stop and wait; otherwise, you may face a fine. Similarly, if left-turning vehicles are approaching during your right turn, you must yield to them. In case of a collision, the right-turning vehicle typically bears greater responsibility.

What to Do If You Fail the Subject 2 Driving Test for the First Time?

If you fail the Subject 2 driving test on your first attempt, you are allowed one retake. If you do not take the retake or fail it again, the current test session ends, and you must reschedule the test after ten days. Within the validity period of your driving skill test permit, you can schedule the Subject 2 and Subject 3 road driving skill tests up to five times. If you fail the fifth attempt, any previously passed subjects will be invalidated. Additional Information: Passing Criteria: The test is scored out of 100, with deductions of 20, 10, or 5 points for various mistakes. To pass: (1) For large buses, tractors, city buses, medium buses, or large trucks, a score of 90 or above is required; (2) For other vehicle types, a score of 80 or above is needed.

Which Light to Watch When Making a Right Turn in a Car?

When making a right turn at an intersection, the driver should first check if there is a dedicated arrow signal for right turns and follow the rule of stopping at red and proceeding at green. Precautions for making a right turn in a car: Before changing lanes for a right turn, the driver should signal in advance. This serves as a warning to vehicles behind as well as to electric bikes, bicycles, and pedestrians. Always check for oncoming straight traffic from the left and yield to them. Observe traffic signals carefully and follow traffic rules. Car turning techniques: Follow the outside-inside-outside principle for turning. To navigate a curve quickly and minimize centrifugal force, make use of the full width of the road and take a wide arc, making the turn as straight as possible. For uphill curves, ease off the throttle and downshift before entering the curve, then accelerate quickly to exit. Before entering the curve, release the throttle to allow the car to enter at a higher speed along the outside of the curve, then downshift one or two gears. Choose the best line and correct the direction while gently applying the throttle.

What Causes the Idle Speed to Increase When Engaging Gear?

Introduction to the causes of increased idle speed when engaging gear: Malfunction of the idle control valve: Normally, electronic fuel injection engines rely on the idle control valve to determine the normal idle speed. During driving, the electronic control unit (ECU) calculates based on the information transmitted by the engine to adjust the intake air volume, thereby altering the engine's idle speed. However, if oil contamination or carbon deposits affect the idle control valve, the ECU cannot receive accurate information, leading to improper idle speed regulation and resulting in excessively high idle speed. You can check whether the idle control valve makes any sound during operation; if there is no sound, it indicates a malfunction. Intake system leakage: Maintaining normal idle speed requires strict control of the intake air volume. When there is a leak in the intake system, the ECU cannot perform accurate calculations, leading to an increase in intake air volume. In such cases, the idle speed will also be excessively high. Fuel injector leakage or clogging: When the fuel injector leaks or becomes clogged, it causes issues in the vehicle's fuel injection system, resulting in either excessively high or low concentration of the air-fuel mixture inside the engine. This inevitably affects the cylinder's operation, leading to unstable idle speed.

Where to Get a Car Remote Key

Car 4S shops can provide remote keys. Below are the specific functions of car remote keys: 1. Close windows after turning off the engine: Press and hold the lock button on the remote key to close the windows. This feature may also be available on ordinary family cars. 2. Find the car in a parking lot: Some car keys have a dedicated car-finding button. For certain vehicles, pressing the lock button twice will make the car emit a beep to indicate its location, making it easier to find the car quickly in crowded parking areas. 3. Automatically open the trunk: Many car models have a trunk-opening button on the remote key. Press and hold the trunk unlock button to open the trunk automatically. 4. Keyless entry: You need to carry the car key. When the key is near the car, it will automatically match the car's decoder. Press the unlock button on the car door handle to unlock the car.
