Why is the score still 0 after the C1 clearance?

A cumulative score of 0 on the driver's license indicates that the holder has no traffic violations or points deducted. Below are relevant details about driver's license scoring: 1. Scoring cycle: The cumulative scoring cycle for road traffic safety violations (i.e., the scoring cycle) is 12 months, with a full score of 12 points, calculated from the date the motor vehicle driver's license was initially issued, and so on in a continuous cycle. The clearance date for the driver's license is the issuance date on the license, and the system automatically clears the score on that date each year. The scoring cycle starts from the 'initial issuance date' of the driver's license, with one year as a cycle, and so on in a continuous loop. 2. Point deduction handling: If the points deducted within a year are relatively few, they will automatically reset to zero at the start of the next cycle, and the score will restart from 12 points. Drivers who accumulate 12 points within a cycle usually need to participate in learning activities organized by relevant departments. In some regions, drivers who accumulate 9 or more points within a cycle also need to attend these sessions. For those with particularly severe violations, measures such as temporary suspension or revocation of the driver's license are often imposed.

How Many Years Can a Statically Flooded Car Still Be Driven?

How many years a statically flooded car can be driven depends on the extent of water immersion. If the damage is not severe and proper maintenance is performed afterward, it can generally be driven for five to six years. Methods to identify a flooded car: 1. Smell: Check for a musty odor inside the car. Flooded cars often have a musty smell in hidden areas such as the floor mats, trunk mats, and under the seats, which are difficult to clean and usually leave evidence. 2. Look: Inspect screws in hidden areas for rust or signs of replacement. Pull back the seats to check for rust or sand in the tracks. Extend the seatbelt fully to see if there are water stains or dirt at the end. 3. Press: Test the function buttons inside the car. If multiple buttons feel sticky or have weak rebound, these components may have been submerged in water. 4. Check: Visit a 4S shop to review maintenance records and check for any engine repair history. If present, it usually indicates a major accident or flooding incident.

How many points will be deducted for driving at 140 km/h on the highway?

It depends on the driving lane, with 3 or 6 points deducted. Here is some information about the point deduction system for learning traffic laws: 1. Purpose: On the surface, the system gives drivers more behavioral points, but it mainly encourages drivers who have been penalized to learn traffic laws, thereby promoting legal awareness. 2. Notes: If a driver accumulates 12 penalty points, their license will be suspended, and they must attend a 7-day course on traffic regulations at the location of the violation within 15 days and pass the exam. Additionally, if a driver accumulates 12 penalty points in one scoring cycle, they cannot participate in the point deduction system for learning traffic laws in the next cycle.

What is the working principle of an air conditioning pressure gauge?

The working principle of an air conditioning pressure gauge is that when the pressure in the system is higher or lower than the rated safe pressure, the disc inside the sensor moves instantaneously, pushing the switch contact to connect or disconnect via the connecting rod. When the pressure drops or rises to the rated recovery value, the disc instantly resets, the switch automatically resets, and the free end of the elastic element generates displacement, directly or after comparison, pushing the switch element to change its on/off state, thereby achieving the purpose of controlling the measured pressure. The manifold pressure gauge is an essential tool for repairing automotive air conditioning systems. Connected to the refrigeration system, it can perform vacuuming, refrigerant charging, and diagnose faults in the refrigeration system. The pressure gauge set has multiple uses, including checking system pressure, charging the system with refrigerant, vacuuming, and adding lubricating oil to the system. The manifold pressure gauge must be connected to the automotive air conditioning system using rubber hoses. Rubber hoses come in many different colors. Typically, the low-pressure side uses a blue hose, connected to the low-pressure side service valve; the high-pressure side uses a red hose, connected to the high-pressure side service valve; and green or yellow hoses are used to connect the vacuum pump or refrigerant tank.

How old must a child be to sit in the front passenger seat on the highway?

Children must be at least 12 years old to sit in the front passenger seat of a car. The car's seat belts are designed according to adult standards and are suitable for individuals weighing 36kg and measuring over 140cm in height. If used for children, the seat belt may press against the child's neck, posing greater risks in the event of an accident. Even if a mother holds a child while riding, it is highly unsafe. Relevant information about car seat belts is as follows: Introduction: Car seat belts are safety devices designed to restrain occupants during a collision, preventing secondary collisions with the steering wheel, dashboard, etc., or avoiding injuries from being ejected from the vehicle during a crash. Working Principle: The retractor contains a ratchet mechanism. Normally, occupants can pull the webbing freely and evenly while seated. However, when the webbing is continuously pulled out and suddenly stops or when the vehicle encounters an emergency, the ratchet mechanism locks automatically, preventing further webbing from being pulled out.
