Will a tire be punctured if it runs over a glass bottle?

A tire that runs over a glass bottle may not be punctured on the first day, but it could still be punctured on the second day. This is because glass fragments may get lodged in the tire tread, and as the tire is used, the pressure on the glass shards can cause them to penetrate deeper, potentially puncturing the tire's inner liner. When inflating a tire, pay attention to the following points: Always use a pressure gauge to check the tire pressure to avoid over-inflation, which could cause the tire to burst. After stopping, wait for the tire to cool down before inflating, as driving increases tire temperature, which affects pressure. Check the valve stem. If the valve stem and core are not properly aligned or have defects, it may be difficult to inflate or measure pressure. Ensure clean air when inflating. The air should not contain moisture or oil, as these can deteriorate the inner tube rubber. Do not exceed the standard pressure significantly and then release air, nor over-inflate due to prolonged inability to inflate while traveling. Over-inflation can overstretch the tire cords, reducing their strength and shortening tire lifespan. Before inflating, clean the valve stem of dust and ensure the valve core is secure. After inflating, apply soapy water (or saliva) to the valve stem to check for leaks (bubbles indicate leaks). Install the valve cap tightly to prevent dirt from entering. When inflating radial tires, their larger contact area and greater deflection may lead to misjudgment of under-inflation or over-inflation. Use a standard pressure gauge for accurate measurement. The recommended pressure for radial tires is 0.5-1.5 kg/cm² higher than that of conventional tires.

Which finger is used for the fingerprint in Subject 2?

Subject 2 fingerprint recording generally requires the use of the thumb, index finger, or middle finger. According to examination regulations, candidate identity verification is required before both Subject 2 and Subject 3 tests, primarily through ID card verification and fingerprint scanning. Theoretically, if fingerprint recording is part of the pre-exam process in your region, it is a mandatory step before the test begins. Below is related information: 1. Definition of Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. 2. Content of Subject 2: The test includes five mandatory items: reversing into a garage, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving.

Is a mock test still necessary for the second attempt at Subject 2?

The necessity of a mock test entirely depends on the candidate's confidence level. If the candidate feels fully prepared, a mock test may not be required. Purpose of the mock test: It aims to familiarize candidates with the exam environment and allows instructors to point out areas prone to point deductions. Therefore, mock tests are absolutely essential—thorough preparation is key to optimal performance. Definition of Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills examination. Content of Subject 2: For car licenses C1 and C2, the test items include five mandatory components: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns).

How Long Does It Take to Practice Driving Before Going on the Road Alone?

The time it takes to practice driving before going on the road alone varies from person to person. Those with a good foundation may only need 2 to 4 hours, while those with a weaker foundation may require 10 to dozens of hours. For better safety assurance, it is generally recommended to practice for about 10 hours. This will help you adapt to most typical road conditions in urban areas. Below are some related points: 1. No highway driving during the probationary period: Generally, drivers can drive on highways only after completing a one-year probationary period after obtaining their license. If traffic violations occur during the probationary period, the period may be extended by another year, making it two years in total. 2. Highway driving during the probationary period: If you need to drive on highways during the probationary period, you must be accompanied by someone with at least three years of driving experience.

What are the differences between the first and second sessions of Subject 3?

There is no difference between the first and second sessions of Subject 3. The only variation is that if a student fails the first session, they will be given a second session as a retake. If the student passes the first session directly, there will be no second session. If the student fails the second session as well, they will have to re-register for Subject 3, but the exam content remains the same. Below is an introduction to Subject 3: 1. Definition of Subject 3: Subject 3, which includes the road driving skills test and the safe and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviated term for the road driving skills and safe and civilized driving knowledge test in the motor vehicle driver's examination. 2. Content of Subject 3: Vehicle preparation, simulated nighttime lighting test, starting, driving in a straight line, gear shifting operations, changing lanes, pulling over, proceeding straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and nighttime driving.
