How many points are deducted for not using turn signals when changing lanes in Shanghai?

Failure to use turn signals when turning a motor vehicle results in a deduction of 1 point. Below is more information about turn signals: Introduction to turn signals: Turn signals are important indicator lights that are activated when a motor vehicle turns to alert vehicles and pedestrians in front, behind, and on either side. The turn signal tube uses a xenon tube, with a microcontroller controlling the circuit, enabling alternating left and right flashing without interruption. Turn signals use a flasher to achieve light blinking; they can mainly be divided into three types: resistance wire type, capacitor type, and electronic type. Function of turn signals: To alert pedestrians or other vehicles of the intended turning direction. To indicate the direction for overtaking or lane changing. When both left and right turn signals are activated simultaneously, it indicates that the vehicle is in an emergency situation, alerting other vehicles to be cautious.

What Mileage Should Not Be Exceeded When Buying a Used Car?

Generally, for private cars, a mileage of 120,000 to 150,000 kilometers over 6 years is considered normal for a used car. Below are detailed explanations regarding purchasing a used car: 1. Choose a newer model if the mileage is similar: Vehicles, like people, age even when not in use. A car with 50,000 kilometers can be considered in its prime, with no major issues and few minor problems. 2. Consider older models with good maintenance: Assuming an average annual mileage of 20,000 kilometers for family cars, if you find a car that has only driven 50,000 kilometers in 6 years, it might indicate the owner took good care of the vehicle, performing regular maintenance, detailing, and cleaning. Thus, even a car with 100,000 kilometers isn't necessarily old, and such well-maintained, older models are worth considering. 3. Age has a greater impact than mileage: From the perspective of a vehicle's actual lifespan, the age of the car affects it more than the mileage, primarily because the actual service life of a car is long, while the impact of mileage is relatively minor. 4. Long actual service life of vehicle components: Components like the engine, chassis suspension, and transmission have very long service lives. Naturally, higher mileage leads to more wear and tear. So, what does a car with 200,000 kilometers mean? It's equivalent to a regular family car being driven for about 10 years. However, in terms of scrapping, a vehicle is only recommended for scrapping after exceeding 600,000 kilometers. Thus, 200,000 kilometers is akin to just reaching adulthood. In reality, these components are designed to last well beyond 600,000 kilometers.

Do I need to bring my own photo to get a driver's license?

When collecting your driver's license, you do not need to bring a photo ID because the photo for the driver's license was already submitted when you enrolled in the driving school. There is no need to submit the photo again; you only need to participate in the license oath ceremony. The requirements for driver's license photos are as follows: Photo time: A recent front-facing, bareheaded, color, single-person half-length photo of the driver's license applicant taken within the last 6 months; Photo size: The photo should be 3.2cm x 2.2cm, with the head length between 1.9cm and 2.2cm, and the head width between 1.4cm and 1.6cm; Requirements: The background color should be white, you cannot wear white clothes, you cannot wear uniform clothing for the photo, and your facial features must be visible. You cannot privately change the driver's license photo because the license needs to be stamped, and the stamp will cover part of the license and the photo. If you change the photo, the stamp will become incomplete, which is also the reason why you cannot wear red clothes when taking the driver's license photo. How to replace or reapply: The driver's license photo can only be changed when applying for or replacing the license. You can apply for a replacement driver's license at the vehicle management office (you can also apply for a replacement even if the license is not lost). You need to prepare the original and a copy of your ID card, a one-inch white background photo, and submit the application for a replacement driver's license at the service window of the vehicle management office.

What could be the reason for suddenly showing no fuel when the tank is half full?

If the fuel gauge suddenly shows no fuel when the tank is half full, it might be due to poor contact of the fuel pump's float-like component. If this issue persists, it should be repaired. The fuel pump is a lightweight and compact pump, categorized mainly into inline, distributor, and unit types. The fuel pump requires a power source to operate, with its lower camshaft driven by the engine's crankshaft gear. Introduction to the functions of the fuel pump: 1. The fuel pump is suitable for transporting various oils, such as heavy oil, diesel, and lubricating oil. With copper gears, it can transport low-flash-point liquids like gasoline and benzene. Some models with stainless steel gears can also transport beverages and corrosive liquids. 2. The fuel pump can also handle liquids containing hard particles or fibers and is suitable for various viscosities. It can withstand temperatures up to 300°C. For transporting high-temperature liquids, high-temperature resistant gear pumps are recommended, capable of handling liquids below 300°C. 3. Many types of fuel pumps feature simple and compact structures, are easy to use and maintain, and have good self-priming capabilities, eliminating the need to fill the pump with liquid before each use. 4. Some fuel pumps are lubricated automatically by the transported liquid, so no additional lubricant is needed during regular operation. 5. Using flexible couplings to transmit power can compensate for minor deviations caused during installation. It also provides effective buffering against unavoidable hydraulic impacts during pump operation.

How Long Should You Practice Driving in a Day?

It is recommended that 2-3 people take turns practicing driving, with each session not exceeding 1 hour and not less than half an hour. Here are the detailed explanations: 1. Limited energy: Practicing driving is physically demanding, requiring both hands and feet to work together while maintaining high concentration. A person's energy and focus are limited, and an adult can typically maintain this for about 40 minutes at a time. Once this limit is exceeded, efficiency drops significantly. 2. Driving cannot be mastered quickly: Developing good driving habits requires time and persistent training, not just a day or two of continuous practice. While diligence can compensate for clumsiness and practice makes perfect, these do not mean achieving mastery in a short time. Diligent practice emphasizes persistence rather than frequency. 3. Intermittent practice is more efficient: Practicing driving, like any work, requires a balance of effort and rest to make it easier. After a few rounds of practice, take a break and let someone else take over. During this time, you can not only rest but also observe others' driving to learn from their strengths and weaknesses.

What causes a clunking sound when braking and starting?

Braking and starting with a clunking sound is due to the brake disc and brake pads sticking together due to rust, causing abnormal noise. This usually occurs after driving in rainy weather and then leaving the vehicle parked for several days without use. The brake disc and brake pads rust and stick together, resulting in noise when the vehicle is started again. This is a normal phenomenon. Below are some related points: 1. Regular inspection: Develop the good habit of checking tires and wheel hub screws before driving to prevent accidents caused by missing screws or flywheel issues. 2. Poor break-in: If new friction pads or a new brake disc are installed, they may not immediately break in properly with each other, leading to abnormal noise.
