How Many Questions Are There in the Traffic Rules Subject 1 Exam?

The Subject 1 exam for the driver's license consists of 100 questions, according to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses." It includes single-choice questions and true/false questions, with each question worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1, also known as the Subject 1 theory test or driver theory test, is part of the motor vehicle driver's license assessment. The exam content covers driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is computer-based with a time limit of 45 minutes. Subject 1 exam content includes: driver's license and motor vehicle management regulations; 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 cargo vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 exam precautions: Candidates should dress appropriately—no slippers allowed. Electronic devices and bags are prohibited in the exam hall. Bring your ID card and queue to enter the waiting area. Observe the instructions and procedures on the large screen before entering the exam hall, and store personal belongings in lockers. Upon entering, verify your identity at the assigned station, locate your seat, and begin the exam. Ensure the camera is aligned with you and follow 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 completion, queue to collect and sign your score report—unsigned reports are invalid. There is no limit to the number of times you can reschedule the Subject 1 exam. If you fail the first attempt, you can retake it once. If you skip the retake or fail again, the exam session ends, and you must reschedule. In contrast, Subjects 2 and 3 allow only five exam attempts. Subjects 2 and 3 must be rescheduled at least 10 days later. If you fail the Subject 3 safety and civilized driving knowledge test, your previously passed road driving skills scores 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 is the field driving skills test. Subject 3 is divided into two parts: road driving skills and safety and civilized driving knowledge. The safety and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4, though this term is not officially recognized (i.e., not mentioned in the Ministry of Public Security's Order No. 123).

Can the Compulsory Traffic Insurance Cover a Broken Car Windshield?

No, the Compulsory Traffic Insurance does not cover the repair costs for your own car's broken windshield, as it is designed to compensate for damages to third-party vehicles and individuals. To claim for your vehicle's damage, you must have purchased a separate vehicle damage insurance. The Compulsory Traffic Insurance is mandatory by the state, and without it, you cannot legally drive on the road. According to the "Road Traffic Safety Law," the traffic management department of the public security authority may detain the motor vehicle, notify the party to provide the corresponding license, mark, or complete the necessary procedures, and may issue a warning or impose a fine ranging from 20 to 200 yuan. Compulsory Traffic Insurance for Vehicles: The full name of the Compulsory Traffic Insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates within the liability limits for personal injuries, deaths, and property losses of victims (excluding vehicle occupants and the insured) caused by road traffic accidents involving the insured motor vehicle. The premium is based on the nationally unified standard rates. However, the price of Compulsory Traffic Insurance varies for different vehicle types, mainly influenced by the number of car seats. Compared to the over 20 exemption clauses in commercial third-party liability insurance, the exemption scope of Compulsory Traffic Insurance covers losses caused by intentional acts of the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses from accidents, offering much broader coverage. Moreover, regardless of whether the insured vehicle is at fault in the accident, the Compulsory Traffic Insurance will compensate within the liability limits, with no deductible or exemption. Introduction to Electronic Insurance Policies: An electronic insurance policy refers to a digital policy issued by an insurance company using digital signature software that complies with the PKI system and an enterprise digital certificate, bearing the electronic signature of the insurance company. An insurance policy, abbreviated as a policy, is the formal written proof of the insurance contract between the insurer and the insured. The policy must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The content recorded in the policy serves as the basis for both parties to fulfill the contract. The insurance policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof marks on paper; Saves time and is convenient, not restricted by time or location, with information universally accessible online anytime, quickly and easily; Allows for reissuance and resending, eliminating worries about losing it. If a paper version is needed offline, it can also be printed or mailed; Facilitates management, as electronic standardization makes it easier for insurance companies and traffic police departments to manage the insurance information of various vehicles.

What is the highest grade of gasoline?

Currently, the highest grade is 100-octane gasoline. Gasoline can be divided into different grades, such as 90#, 93#, 97#, 98#, etc. Some regions also offer 100# gasoline. These different labels represent different octane ratings. The higher the grade, the higher the octane rating, which means the gasoline has better anti-knock performance. Octane rating is a numerical value representing the gasoline's resistance to knocking. The higher the anti-knock performance, the better the gasoline's quality. The octane rating of gasoline is a unit of its anti-knock performance in a lean mixture. Under specified conditions, when the anti-knock performance of the sample is the same, its value equals the volume percentage of isooctane contained in the standard fuel. For example: 93# gasoline has an octane rating of 93, meaning it has the same anti-knock performance as standard gasoline containing 93% isooctane and 7% n-heptane. Similarly, 97# gasoline has the same anti-knock performance as standard gasoline containing 97% isooctane. 100# base oil is produced from high-quality crude oil through vacuum distillation, solvent dewaxing (a process where lubricant crude oil is diluted with solvent and frozen to precipitate wax crystals, thereby reducing the freezing point of the base oil), and clay refining (a process using the adsorption capacity of activated clay to adsorb various impurities onto the clay, which is then filtered out to remove all impurities). Its performance advantages include good viscosity-temperature characteristics, low evaporation loss, excellent low-temperature fluidity, good oxidation stability, and strong solubility for oxidation products and additives. It is recommended that vehicles designed for lower-grade gasoline will not be damaged if higher-grade gasoline is mistakenly used, but the increase in octane rating may alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in a noticeable drop in performance. Using lower-grade gasoline in vehicles designed for higher grades may cause engine knocking. Because the octane rating is too low, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If combustion occurs before the spark plug ignites, resistance will be generated during the upward stroke. This resistance can make the engine run very unstably. If the knocking is mild, it may only increase noise without significant damage to the engine. However, if the knocking is severe, it indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Is it illegal to use autonomous driving in cars?

Using autonomous driving in cars is not illegal. In China, when accidents involving driverless cars occur, liability can only be pursued against the producers or sellers. In China, current laws have almost no regulations regarding autonomous vehicles. The Road Traffic Safety Law does not address the legal regulation of autonomous vehicles. For example, provisions in Articles 2, 16, and 19 of the Road Traffic Safety Law concerning vehicle testing, assembly, modification of motor vehicles, as well as driver's licenses and subjects, do not apply to autonomous vehicles. Additionally, although Article 76 of the Road Traffic Safety Law stipulates the allocation of liability for personal injuries, deaths, or property losses caused by traffic accidents involving motor vehicles, it does not directly specify the liability allocation for autonomous vehicles.
