How many days does it take to learn Subject 3?

Subject 3 generally takes varying amounts of time to learn depending on the student's learning ability. Those who learn quickly may take about 2-4 days, typically requiring 10-15 practice sessions. Slower learners may need around 7 days. Subject 3 includes the road driving skills test and the safety and civilized driving knowledge test. Below is an introduction to the driving test subjects: Subject 1: A test on road traffic laws, regulations, and related knowledge. The structure and basic question types of the test database are formulated by the Ministry of Public Security, while provincial traffic management departments establish their own test databases based on local conditions. Subject 2: A test on site driving skills, including reverse parking, hill start, right-angle turns, curve driving, and parallel parking. In cities like Shanghai, Subject 2 consists of nine mandatory tests: reverse parking, right-angle turns, parallel parking, tunnel driving, parking for toll collection, curve driving, narrow road U-turns, emergency stops, and hill starts. Subject 3: A test on road driving skills, including pre-driving checks (walking around the vehicle counterclockwise, fastening the seatbelt, turning on the left signal, shifting gears, releasing the handbrake, and honking), starting, straight-line driving, lane changes, passing intersections, pulling over, crossing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, U-turns, and night driving. Subject 4: A test on safety and civilized driving knowledge, covering related safety and civilized driving concepts.

Is Car Window Tinting Necessary?

It can be applied or not, depending on personal preference. The advantages of car window tinting are introduced as follows: One-way visibility (privacy): Some car windows come with one-way visibility from the factory, but others do not, so some car owners use window tinting to achieve this feature. Anti-explosion function: It can enhance the anti-explosion performance of car windows, making them less likely to shatter. Even if the glass breaks, the fragments will adhere well to the window and not fly around, causing injury. Heat insulation and energy reduction: Although the scope of car window tinting is broad, in a narrow sense, it refers to car window film, also known as "car heat insulation film" or "car sun film." As the name suggests, heat insulation (blocking sunlight/heat) is the main purpose of car window tinting. UV protection: When passengers are in the car for long periods, the human body is basically in a static state, making it more susceptible to UV damage, which can cause skin diseases. Especially in summer, increased UV rays can not only burn the skin but also cause the car's interior, such as seats and dashboard panels, to fade or deform due to sun exposure.

Where can I buy a water blocking airbag?

You can purchase it directly online. Here is an introduction to the function of the water blocking airbag: The water plug is a water blocking airbag, which mainly serves a protective function. Function 1: Some smaller water plug holes are processing channels during machining, and they are blocked with water plugs after the machining is completed. Function 2: Some larger water plug holes are designed to protect the engine block or cylinder head. If an engine filled with water in winter is forgotten to be drained, the water plug will expand first when the water freezes, thereby protecting the engine block or cylinder head to a certain extent. Working principle of the airbag water blocking: It uses a high-quality rubber airbag that is inflated to expand. When the gas pressure inside the airbag reaches the specified requirements, the airbag fills the entire pipe cross-section, and the friction between the airbag wall and the pipe blocks the water leakage, thereby achieving the purpose of no water seepage in the target pipe section.

What is the handbrake called?

Handbrake is called auxiliary brake. The function of handbrake: After the vehicle is parked, tighten the handbrake to make the brake shoe stick to the brake drum or brake disc, so that the vehicle is in a braking state to prevent dangerous movement of the vehicle. However, when driving at high speed, the braking force of the handbrake is very small. If the owner pulls the handbrake at high speed, the rear wheels are easily locked and the cable will break. At this time, the vehicle will skid or even roll over. The professional name of handbrake: Auxiliary brake, which is different from the principle of the brake. It uses steel wire to connect to the rear brake shoe to brake the car. The handbrake is a system with a high usage rate. Reasonable and correct use can make future use smoother, especially for mechanical handbrakes with a large amount. It is best to use them according to the correct method.
