According to Article 46 of the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' applicants who pass the exam must receive no less than half an hour of safety education on civilized driving and case studies of traffic accidents, and participate in the oath-taking ceremony for receiving the license. Subject 4, also known as the theoretical exam for Subject 4 or the driver's theoretical exam, is part of the assessment for obtaining a motor vehicle driving license. Below is an introduction to the Subject 4 exam: 1. Scope: Depending on the type of driving license being applied for, 50 questions are proportionally selected from the corresponding Subject 4 question bank. For car licenses, questions are selected from 1235 questions, and for large vehicle licenses, questions are selected from 1235 questions, with each question worth 2 points. 2. Time: The exam duration is 45 minutes. If 12 points (6 questions) are answered incorrectly during the exam, the session will be terminated. 3.

Does the Dash Cam Continue Recording After the Car is Turned Off?

The dash cam can continue recording after the car is turned off. The parking monitoring function primarily relies on the dash cam automatically starting to record when it detects vibrations. This functionality is achieved through a built-in high-sensitivity gravity sensor. Operating time of the dash cam: If the dash cam is wired to a constant power source during installation, providing 24-hour power supply, and if the parking monitoring, time-lapse recording, or motion detection features are enabled on the dash cam, then after the car is turned off, the dash cam will start recording upon detecting vibrations and automatically save the video without overwriting it. If there is movement within the range of the dash cam's camera, the motion detection feature will activate and automatically start recording. With time-lapse recording enabled, the dash cam can continue recording around the clock even after the vehicle is turned off. Important notes: Even though the dash cam can record after the car is turned off, it's important to be aware that dash cams have blind spots. Single-lens dash cams can only capture the front view, dual-lens dash cams can capture the front and rear, and 360-degree panoramic dash cams can capture all angles. For safety considerations, it is recommended to park the vehicle in an area with surveillance cameras.

What are the reasons for engine coolant deficiency?

Here are the reasons for engine coolant deficiency: 1. When the water temperature rises, the steam inside the water channel forces the coolant out of the reservoir. 2. Poor performance of the water pump or thermostat can cause the circulating system's water temperature to become too high, leading to excessive pressure inside the radiator and cooling system, which results in coolant flowing out from the reservoir. 3. Poor sealing of the cylinder gasket. Below are some related points: 1. Lack of coolant in a car means the car's engine and radiator lack protection. 2. Insufficient coolant in a car can affect the radiator's heat dissipation efficiency, failing to achieve the necessary cooling effect. This disrupts the normal circulation of coolant, leading to high temperatures and, in severe cases, can cause engine damage.

How to Spray Windshield Washer Fluid?

Windshield washer fluid spray switch is located on the right-hand stalk of the steering wheel, which also operates the wipers. Pull the stalk towards yourself to spray the fluid. Windshield washer fluids are mainly divided into three types: summer-use fluid, winter-use antifreeze fluid, and special antifreeze fluid. Summer-use fluid is primarily used to remove insect residues from the windshield. It is important to choose the appropriate windshield washer fluid based on different climates and temperature conditions. Below are the key features of windshield washer fluids: 1. Cleaning Performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal. 2. Antifreeze Performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. 3. Anti-fog Performance: A single-molecule protective layer forms on the windshield surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision.
