Engine oils from different brands should not be mixed. Explanation: This is because engine oils produced by different manufacturers may contain varying chemical compositions of additives. When lubricants with different additive chemistries are mixed together, chemical reactions may occur between the additives. If you find yourself in a situation where the oil level is insufficient during operation and have no choice but to mix oils, try to select oils of similar types and the same viscosity to avoid potential negative consequences. Function of engine oil: Engine oil serves to lubricate and reduce friction among internal engine components, assist in cooling, provide sealing to prevent leaks, and act as a shock absorber. If improper lubrication occurs due to mixing oils, it can cause significant damage to the engine.

Will the car move after releasing the brake pedal?

After releasing the brake pedal, the car generally will not move. Below is an introduction to the braking system: Introduction: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. Techniques: Many braking actions are emergency stops that are unavoidable. In such cases, it is essential to pay attention to braking techniques. Vehicles without ABS (Anti-lock Braking System), which is common in older models, may experience wheel lock-up if the braking force is too strong during emergency stops. Therefore, when braking in older vehicles, it is advisable to use intermittent braking (pump braking) as much as possible.

Can I Wear Colored Contact Lenses for the Subject 1 Test?

You can wear colored contact lenses for the Subject 1 test. There are no explicit regulations prohibiting it, but avoid wearing clothing such as tank tops, vests, or slippers, as these may prevent entry into the examination hall. If you wear hats, masks, scarves, or other facial coverings, you may enter after removing them. Important notes for the Subject 1 test: Candidates should dress appropriately—no slippers are allowed, electronic devices and bags are prohibited in the examination hall, and you must bring your ID card. Line up to enter the waiting area, observe the instructions and procedures on the screen, and store personal belongings in lockers before entering the examination hall. At the identity verification station, you will be assigned a seat. Once seated, begin the test, ensuring the camera is properly aligned with your face and following exam rules. If you fail the first attempt, a free retake is available on the same day. Failing again requires payment and rescheduling. After completion, line up to collect and sign your score report—unsigned reports are invalid. The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" clearly state that candidates can take the Subject 1 test twice on the same day. If the first attempt is unsuccessful, a free retake is allowed. Failing the second attempt terminates the session, and a new appointment can be made after ten days. Subject 1, also known as the theoretical driving test, is part of the driver's license examination. It covers driving theory, road safety laws, local regulations, and related knowledge. The test consists of 100 questions, including single-choice and true/false questions, each worth 1 point (total 100 points). If you answer 11 questions incorrectly, the system will automatically submit and end the test. The Subject 1 test is computer-based and has a 45-minute time limit. Subject 1 test content includes: driver's license and motor vehicle regulations; road conditions and traffic rules; traffic violations and penalties; traffic accident handling procedures; basic vehicle knowledge; local regulations; braking systems and safety features for large/medium buses and trucks; specialized knowledge for wheeled machinery, trams, and trolleybuses. There is no limit to the number of Subject 1 test appointments. Each subject allows one initial test and one retake if failed. Skipping the retake or failing it again terminates the session, requiring a new appointment. In contrast, Subjects 2 and 3 allow only five attempts each, with appointments available after ten days. Failing the Subject 3 safe driving knowledge test does not invalidate the passed road skills test. The driving test consists of three subjects: Subject 1 (theoretical knowledge), Subject 2 (field driving skills), and Subject 3 (road driving skills and safe driving knowledge). The safe driving knowledge test follows Subject 3, often referred to as "Subject 4," though this term is unofficial (not mentioned in the Ministry of Public Security’s Order No. 123).
