How Long Does It Take to Retake the Subject 1 Exam?

The retake time for the exam is 45 minutes. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the Subject 1 exam can be taken twice on the same day. If the first attempt is unsuccessful, a second retake is allowed free of charge. If the second attempt also fails, the Subject 1 exam is terminated, and the candidate must wait ten days before scheduling another exam. Subject 1, also known as the theoretical exam or driver's theory test, is part of the motor vehicle driver's license assessment. The exam content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is conducted via computer. The Subject 1 test consists of 100 questions, divided into single-choice and true/false questions, each worth 1 point, totaling 100 points. If a candidate answers 11 questions incorrectly, the system will automatically submit the exam and end the test. Subject 1 Exam Content: Regulations on driver's licenses and motor vehicle management; Road traffic conditions and rules; Road traffic safety violations and penalties; Road traffic accident handling regulations; Basic knowledge of motor vehicles; Local regulations; Knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; Specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 Exam Notes: Candidates should dress appropriately for the exam; no slippers are allowed. Electronic devices and bags are prohibited in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen, and store personal belongings in lockers before entering the exam room. At the exam room, the identity verification desk will assign a seat. Once seated, begin the exam. Ensure the camera is aligned with you and follow exam discipline. If you fail the first attempt, a same-day retake is allowed. If you fail again, you must pay to reschedule. After the exam, queue to collect your score report and sign it. Unsigned reports are considered invalid. There is no limit to the number of times you can schedule the Subject 1 exam. Each subject exam allows one retake if the first attempt fails. If you skip the retake or fail it, the exam is terminated, and you must reschedule. For Subject 2 and Subject 3, there are only five exam attempts. Subject 2 and Subject 3 exams can be rescheduled after ten days. If you fail the Subject 3 safe driving knowledge test, your passed road driving skills test results remain valid. There are three subjects in the driver's license exam: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge exam. Subject 2 refers to the field driving skills exam. Subject 3 is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security's Order No. 123) does not include "Subject 4."

What Octane Gasoline Should an Audi A4 Use?

Audi A4 should use 95-octane gasoline. This octane rating is recommended in the vehicle's official owner's manual. In addition to checking the owner's manual for the appropriate gasoline octane, you can also find this information on the fuel filler cap, which will indicate the recommended octane. Typically, the required octane can also be determined by the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the use of new technologies, the compression ratio alone cannot determine the required octane, as high-compression engines can also be tuned to use lower-octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the octane rating, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong octane gasoline in an Audi A4, simply switch back to the correct octane after the tank is empty. However, long-term use of the wrong octane can have the following effects: Using a higher octane gasoline in a vehicle designed for lower octane will not cause damage, but the increased octane can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using a lower octane gasoline in a vehicle designed for higher octane can cause engine knocking. The significantly lower octane reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to severe engine damage.

How many items are there in the 2021 C1 Subject 2 test?

The C1 Subject 2 test is mainly divided into five items: reversing into a garage, parallel parking, curve driving, right-angle turning, and hill start. For automatic transmission (C2), the hill start is not included. In some regions, there is an additional item of high-speed card collection. A C1 driver's license allows driving small and micro passenger vehicles, among others. Introduction and tips for the Subject 2 test: Before starting the car during the Subject 2 test, be sure to adjust the seat height and rearview mirrors to ensure a wide field of vision, and fasten the seat belt. During the test, do not stop unless the system announces a failure. Parallel parking: Park the car in the designated space without crossing or touching the lines. Tips: Remember to find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the car's speed. Hill start: Drive slowly up the hill and stop within the designated area. Tips: Remember to engage the handbrake, turn on the left turn signal when starting, release the handbrake, stabilize the clutch, and gently press the accelerator while releasing the clutch to avoid stalling or rolling back. Right-angle turning: Prepare to turn 90 degrees while driving straight without crossing or touching the lines. Tips: Find the reference point before turning and coordinate with the car's speed. Curve driving (S-curve): Drive slowly through the S-curve without crossing or touching the lines. Tips: Control the speed, drive slowly, and coordinate the timing of turning the car's front. Reversing into a garage: Reverse the car into the garage without stalling or crossing/touching the lines. Tips: Control the speed, find the reference point, and make minor adjustments if there is any deviation observed in the rearview mirror. C1 driver's license passing standards: Traffic regulations and related knowledge—90 points to pass. Field driving—80 points to pass. Road driving—80 points to pass. Subject 2 deduction items: Reversing into a garage: If the car body crosses the line, 100 points are deducted, and the test is failed. If the car is not fully parked in the garage, 100 points are deducted, and the test is failed. Stopping midway deducts 5 points each time. Failing to complete the test within the specified time deducts 100 points, and the test is failed. Parallel parking: If the car body crosses the line after parking, 100 points are deducted, and the test is failed. Stopping midway deducts 5 points each time. If the tires or car body touch the curb line while driving, 10 points are deducted. Failing to complete the test within the specified time deducts 100 points, and the test is failed. Curve driving: If the wheels touch the road edge line, the test is failed. Stopping midway results in failure. Driving in a gear lower than second deducts 5 points. Right-angle turning: If the wheels touch the road edge line, the test is failed. Stopping midway deducts 5 points each time. Hill start and parking: If the car's front bumper or motorcycle's front axle is not aligned with the pole line and exceeds 50 cm, the test is failed. If the start time exceeds the specified time, the test is failed. If the car's front bumper or motorcycle's front axle is not aligned with the pole line but does not exceed 50 cm, 10 points are deducted. If the car body is more than 30 cm but less than 50 cm away from the road edge line after stopping, 10 points are deducted. If the parking brake is not engaged after stopping, 10 points are deducted.

What Documents Are Required for a Driver's License Medical Examination at the Hospital?

Here are the materials you need to bring for the driver's license medical examination: 1. ID card: Original ID card and a photocopy of it. 2. Pen: You will need to fill out forms during the examination. Borrowing a pen from someone else at the last minute can waste a lot of time and may affect your queue speed. 3. Glue stick: Needed for attaching photos. Alternatively, you can bring two pieces of double-sided tape, enough to attach one photo. 4. Glasses for nearsightedness: The examination requires a vision of 4.9, but nowadays, many people who don't usually wear glasses find it hard to meet this standard. Therefore, borrowing a pair of glasses that fit well in advance is particularly important.
