What to Do If You Forget the Electronic Signature for Subject One?

This issue has different requirements in different places. In some areas, forgetting the electronic signature doesn't matter, as you've already entered your name and ID number before the exam. In other places, it may be considered an invalid test, requiring a retake. Here are some precautions for the Subject One exam: 1. Confirm the test center in advance: After scheduling the Subject One exam, make sure to confirm the test location. Arrive at the venue one hour early on the exam day. 2. Bring all necessary documents: Do not lose the admission ticket. You must bring a valid ID card for the exam and queue up to enter the test center. 3. Verify your information before answering: Check if the information on the screen matches yours. Ensure you are facing the camera properly. If your image is incomplete or not captured, your score may be deemed invalid. 4. Pay attention to commonly mistaken questions: During the exam, be mindful of questions you often get wrong. Careful reading of the questions is crucial. 5. Stay calm: Answer the questions patiently, as there is ample time to complete them.

What Type of Driver's License is Required for Electric Vehicles?

Electric vehicles require a Class C driver's license. The length, width, and speed of electric vehicles are the same as those of motor vehicles, with a maximum speed of 60 km/h. Their performance far exceeds that of elderly mobility scooters, so electric vehicles are still classified as motor vehicles, and drivers must hold a Class C driver's license to drive them on the road. More details are as follows: 1. According to national regulations, electric vehicles must comply with the relevant provisions of the "National Motor Vehicle Manufacturers and Products Announcement" issued by the Ministry of Industry and Information Technology to be registered. They must also have a vehicle qualification certificate, purchase invoice, tax payment certificate, compulsory traffic insurance, etc. Vehicles not included in the "Road Motor Vehicle Manufacturers and Products Announcement" cannot be registered as per regulations. 2. According to the "Road Traffic Safety Law" and related laws and regulations, the state implements a registration system for motor vehicles. Only after being registered by the traffic management department of the public security authority can motor vehicles be driven on the road. One of the bases for the traffic management department to register motor vehicles is the products listed in the "Announcement" issued by the national motor vehicle product authority. 3. If the electric vehicle purchased by a citizen is a product listed in the "Announcement," meaning the vehicle's information can be found in the vehicle directory of the vehicle management office, they can apply for the corresponding driving license type as listed in the "Regulations on the Application and Use of Motor Vehicle Driving Licenses." The registration procedures for electric vehicles that meet the relevant conditions are the same as those for ordinary motor vehicles.

Are 92 and E92 gasoline interchangeable?

92 and E92 gasoline can be used interchangeably, as they share the same anti-knock properties, volatility, oxidation stability, corrosion resistance, and environmental requirements. The differences between 92 and E92 gasoline: 92-octane gasoline is regular unleaded gasoline without any alcohol content, while E92 gasoline refers to ethanol-blended gasoline, which contains 10% alcohol. The designation method involves adding the letter 'E' before the original gasoline grade. In terms of pricing, E92 gasoline is generally cheaper. Benefits of using E92 gasoline in cars: Since gasoline combustion significantly contributes to environmental pollution, many cities have introduced ethanol-blended gasoline to replace traditional gasoline in order to protect the atmospheric environment. Ethanol gasoline also has excellent cleaning properties, as ethanol can help dissolve and clean impurities in the car's fuel tank or fuel lines. Drawbacks of using E92 gasoline: Ethanol has a high heat of vaporization, and its evaporation temperature under theoretical air-fuel ratio conditions is higher than that of conventional gasoline. This affects the formation of the air-fuel mixture and combustion speed, leading to reduced vehicle power, fuel economy, and cold-start performance, which negatively impacts acceleration.

What is the General Weight of a Sedan?

Sedans vary in weight depending on brand, model, vehicle configuration, and engine differences, with typical weights ranging from 100-200 kg. Detailed Introduction to Vehicle Weight: Automotive Design Indicators: The weight of a car, also known as curb weight, refers to the total mass of the vehicle when equipped according to factory specifications, including items like spare tires, tools, and all necessary fluids. This weight is closely related to the car's design, manufacturing, and industrialization levels. Curb weight represents the vehicle's own mass, encompassing the weight under normal driving conditions plus any additional accessories. Relationship with Fuel Consumption: Curb weight is a significant factor affecting a car's fuel consumption. There is a proportional relationship between fuel usage and curb weight—the heavier the vehicle, the higher the fuel consumption. Reasons for Weight Differences in Sedan Engines: Sedan engines are made from materials such as cast aluminum, cast steel, and cast iron. Depending on the vehicle classification, engine designs vary in displacement, number of cylinders, and consequently, weight. For the same material, a 4-cylinder engine is lighter than a 6-cylinder, a 6-cylinder is lighter than an 8-cylinder, and an 8-cylinder is lighter than a 12-cylinder. Generally, minivan engines are lighter than those in compact cars, and compact car engines are lighter than those in mid-sized vehicles. The engine of a minivan can typically be moved by hand, usually weighing under 100 pounds, whereas the engine of a large truck can weigh several hundred pounds or even exceed a ton.

How Many Questions Are There in Subject 1 Exam?

The Subject 1 exam for a driver's license consists of 100 questions, as stipulated in the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses.' These questions are divided into single-choice questions and true/false questions, with each question worth 1 point, totaling 100 points. If a candidate answers 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1, also known as the theoretical test or driver's theory exam, is part of the motor vehicle driver's license assessment. The exam content includes the theoretical basis of driving, road safety laws and regulations, local regulations, and other related knowledge. The exam is conducted on a computer, with a time limit of 45 minutes. Subject 1 exam content: Regulations on driver's licenses and motor vehicle management; Road traffic conditions and regulations; Road traffic safety violations and penalties; Regulations on road traffic accident handling; 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 precautions: Candidates should pay attention to their attire during the exam; no slippers are allowed, and electronic devices and bags are prohibited in the exam hall. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in a locker before entering the exam hall. Upon entering, verify your identity at the designated area to be assigned a seat. Once seated, begin the exam, ensuring the camera is aligned with you and adhering to exam discipline. If you fail the first attempt, a retake is available on the same day. 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 reschedule the Subject 1 exam. Each subject can be taken once, with one retake allowed if you fail. If you do not take the retake or fail the retake, the exam process ends, and you must reschedule. In contrast, Subject 2 and Subject 3 have only five exam attempts each, and rescheduling for Subject 2 and Subject 3 must be done at least ten days later. If you fail the Subject 3 safe and civilized driving knowledge test, your previously passed road driving skills test results remain valid. The driver's license exam consists of three subjects: 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 and civilized driving knowledge. The safe and civilized 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 a 'Subject 4.'

What is the passing score for C2 Subject 2?

The passing score for C2 Subject 2 is 80 points. According to Article 35 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses', the passing standards for each subject examination are as follows: the full score for Subject 2 is 100 points. For large buses, trailers, city buses, medium-sized buses, and large trucks, a score of 90 or above is required to pass. For other vehicle types, a score of 80 or above is sufficient. The C2 Subject 2 examination consists of four items: reversing into a garage, parallel parking, curve driving, and right-angle turning. Compared to the C1 manual transmission test, it excludes the hill start item. According to Article 25 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses' (Ministry of Public Security Order No. 123), starting from June 1, 2021, the C2 and C5 Subject 2 tests no longer assess hill start and stopping. Reversing into a garage is one of the more challenging items in the Subject 2 test, which is why many test centers place it as the first item. The key points for reversing into a garage are: the steering wheel's full-lock point, the 30 cm correction point, and the stopping point inside the garage. The vehicle must follow the designated route and sequence. The vehicle must enter the garage during reversing and must not cross the lines. Parallel parking focuses on aligning the front line of the garage with the rear wheels, spotting the rear corner in the side mirror, and maintaining the distance between the wheel and the left dashed line. After parking, the wheels do not need to be straightened, and the turn signal must not be forgotten when exiting. The vehicle body must not cross the lines after stopping inside the garage. During driving, the tires must not touch or press the lane boundary lines. Curve driving, commonly known as the S-curve, can often be completed by students with good vehicle control simply by feel, indicating that the S-curve is not particularly difficult. However, some students may misjudge the line positions during the actual test, leading to immediate failure by crossing the lines. The key to the S-curve is observing the position of the hood marker points relative to the boundary lines. The wheels must not press the road edge lines. Right-angle turning is actually less difficult and can be seen as a simplified version of the exiting part of the reversing into a garage item. The method for finding the reference points is the same as for exiting: observing the relationship between the hood's horizontal line and the front line (either aligning or delaying). Care must be taken to ensure the wheels do not press the road edge lines. Generally, the required training hours for C1 Subject 2 are 16 hours, while for C2 Subject 2, they are 14 hours. Completing the required training hours is a basic requirement for taking the Subject 2 test. Training hours can only be increased, not reduced. If additional test items are added, corresponding training hours must also be increased. Each training hour is 60 minutes, with effective teaching time not less than 45 minutes. If you fail the Subject 2 test, you can retake it once. If you fail the retest, the examination process is terminated, and you must reschedule the test after ten days. If you fail five consecutive test attempts (including retests, totaling 10 attempts), all previously passed subject scores will be invalidated, and you must start over from Subject 1.
