What does ACC mean in cars?

Why was the First Examination Site in Guandu District Closed?

The closure of the First Examination Site in Guandu District is due to continuous heavy rainfall, resulting in significant water accumulation. Below are the specific details of the new driving test regulations: Adjustment of test scheduling time: For obtaining a small automatic transmission vehicle driver's license, the interval for scheduling the Subject 3 test has been shortened from 30 days after passing Subject 1 to 20 days. For upgrading to a large or medium-sized passenger or truck driver's license, the interval for scheduling Subject 3 has been reduced from 40 days after passing Subject 1 to 30 days. Adjustment of cross-regional subject test attempts: For small vehicle driver's license applications, the number of times applicants can request a change of examination location has been increased from 1 to no more than 3 times, meeting the demand for cross-regional testing. Reduction of proxy materials: If applicants cannot promptly handle license replacement or renewal and other traffic management services, they can authorize others to handle these matters via the Traffic Management 12123 platform without the need for a paper power of attorney.

What does the engine oil grade 10w40 mean?

The number 10 represents the minimum applicable temperature of the oil at -25 degrees Celsius, W stands for Winter, and 40 indicates the high-temperature viscosity of the oil, which is the meaning of 10w40 engine oil. The oil grade typically denotes viscosity and quality. The oil grade consists of two parts: classification and viscosity specification, with specific interpretations as follows: w represents the cold-start performance, and the smaller the number before w, the easier it is to start the engine in cold weather. Common grades include 0w, 5w, 10w, and 15w. The number 40 indicates the viscosity characteristics of the oil at high temperatures. High-viscosity oils (with higher values) may be more suitable for high-speed driving or heavy-duty vehicles. The number after w is an indicator of the oil's high-temperature resistance. The larger the number, the better the oil's protective performance at high temperatures. The grade following the oil classification represents its viscosity specification. For example, in "15w-40, 5w-40," the lower the number before w, the better the engine protection during cold starts. For instance, 5w represents resistance to external temperatures as low as -30°C, while 20w can withstand temperatures as low as -15°C. The number after w represents the oil's kinematic viscosity at 100°C, with higher numbers indicating higher viscosity. The viscosity of lubricating oils is often labeled using the SAE grade, where SAE stands for the "Society of Automotive Engineers." Internationally, the SAE (Society of Automotive Engineers) viscosity grade and API (American Petroleum Institute) quality grade are widely adopted. When selecting engine oil, consider the following precautions: Choose oil based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Multi-grade oils are preferred because they are economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oils, they may appear darker prematurely and have lower oil pressure compared to conventional oils during use, which is normal.

Is a Power of Attorney Required for Vehicle Inspection in Another Location?

Vehicle inspection in another location does not require a power of attorney. According to relevant regulations, vehicle annual inspections are "nationwide accessible," meaning small cars, trucks, and medium-sized buses can undergo vehicle inspections directly in provinces other than the registration location. Upon passing the inspection, the inspection compliance mark can be directly applied for without the need for delegated inspection procedures. The process for out-of-town annual inspection includes: 1. Vehicle submission for inspection: Once the delegated vehicle annual inspection procedures are completed, the owner drives the vehicle to the inspection hall next to the vehicle management office for on-site testing; 2. Printing the annual inspection compliance certificate: After the vehicle passes the inspection, the vehicle inspection report is taken to the window of the vehicle management office's service hall to print the inspection compliance mark; 3. Online information transmission back to the original registration vehicle management office: After the vehicle annual inspection is completed, the vehicle annual inspection information will be transmitted back to the original registration location's vehicle management office via the internet, and the next year's inspection will follow the same process.

Is the upward turn signal left or right?

Pushing the turn signal lever upward indicates a right turn. The light switch is located on the lever behind the left side of the steering wheel. Using your left hand to push the lever downward activates the left turn signal, while pushing it upward activates the right turn signal. When the turn signal is activated, the front, rear, and side turn signal lights will flash simultaneously to alert nearby vehicles and pedestrians. Turn signal lights are installed at both the front and rear of the vehicle. Some cars also have turn signal lights on the sides, rear window glass, or side mirrors. Drivers are advised to activate the corresponding flashing indicator in advance before turning to warn pedestrians or vehicles in front of or behind the car, indicating the intended direction of travel. Types of turn signal lights: They are divided into three categories: resistance wire type, capacitor type, and electronic type. The resistance wire type can be further classified into thermal wire type (electrothermal) and wing type (spring-loaded). The electronic type can be divided into hybrid (relay with contacts and electronic components) and fully electronic (without a relay). The spring-loaded flasher operates on the principle of thermal expansion and contraction, using the heat effect of current to cause sudden movement of the spring, which connects and disconnects the contacts to achieve light flashing. Turn signal light tube structure: The tube uses a xenon lamp, with a microcontroller-controlled circuit that enables continuous alternating flashing of the left and right lights.

Will demerit points before license upgrade be counted towards the upgraded driver's license?

Demerit points before license upgrade will be counted towards the upgraded driver's license. You can apply for a license upgrade if you have not accumulated 12 demerit points in the most recent three consecutive scoring cycles before applying. Medium-sized bus driving license category: You must have held a driving license for small cars, small automatic transmission cars, low-speed trucks, or three-wheeled vehicles for more than three years, with no full demerit point record in the most recent two consecutive scoring cycles before applying; or have held a driving license for city buses or large trucks for more than one year, with no full demerit point record in the most recent scoring cycle before applying. Tractor driving license category: You must have held a driving license for medium-sized buses or large trucks for more than three years, with no full demerit point record in the most recent two consecutive scoring cycles before applying; or have held a driving license for large buses for more than one year, with no full demerit point record in the most recent scoring cycle before applying. Large bus driving license category: You must have held a driving license for medium-sized buses or large trucks for more than five years, with no full demerit point record in the most recent three consecutive scoring cycles before applying; or have held a driving license for tractors for more than two years, with no full demerit point record in the most recent scoring cycle before applying.

Can you make a U-turn on a single white dashed line?

U-turns are allowed on white dashed lines, provided there are no signs prohibiting U-turns or left turns, or separate U-turn traffic signals. Vehicles can make a U-turn without affecting normal traffic flow and ensuring safety. Scenarios where U-turns are permitted: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, a U-turn can be made. If there is a U-turn traffic signal, follow the signal's instructions. In the absence of a signal, make the U-turn based on the specific situation, ensuring it does not hinder other vehicles or pedestrians. Intersections without explicit U-turn or left-turn prohibition signs: U-turns are allowed where there are no signs explicitly prohibiting them. 'No explicit prohibition' means the intersection lacks signs like 'No U-turn,' 'No left turn,' or solid center lines, allowing confident U-turns. Yellow grid lines also permit U-turns: Yellow grid lines are no-stopping zones, typically marked at intersections prone to congestion due to temporary stops, important facility entrances, or other necessary locations. Stopping on these lines (including waiting for traffic lights) is a violation. However, U-turns are allowed in yellow grid line areas unless there is a central barrier, as they are equivalent to 'U-turn permitted.' Intersections with U-turn traffic signals: This is straightforward—if there is a U-turn signal, proceed only when it is green. Simultaneous 'No left turn' and 'U-turn permitted' signs: U-turns are allowed even if left turns are prohibited, but 'No U-turn' does not mean 'No left turn.' Points to note when making U-turns at intersections: Observe road markings—solid lines prohibit U-turns under any circumstances. Continue driving to find a suitable spot. If there is a 'No left turn' sign, U-turns are also prohibited at that intersection, as U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. U-turns are not allowed from the second left-turn lane. Always yield to oncoming traffic when making a U-turn. Failing to do so makes you liable for any accidents. Near intersection stop lines, lanes often have directional arrows. Not all leftmost lanes have left-turn arrows; some may have straight arrows, prohibiting U-turns even without explicit signs. U-turns on crosswalks are prohibited and constitute a traffic violation.
