The main differences between Subject 1 and Subject 4 include: the number of test questions, question types, proportion of exam content, and exam focus. The basis comes from the "Regulations on the Application and Use of Motor Vehicle Driving Licenses". Number of test questions: The most obvious difference between Subject 1 and Subject 4 is the number of test questions. Subject 1 has 100 questions, while Subject 4 only has 50 questions. In Subject 1, the test will automatically submit if more than 10 questions are answered incorrectly, while in Subject 4, the test will automatically submit if more than 6 questions are answered incorrectly. Question types: Subject 1 consists of 100 questions, each worth 1 point, with a total test time of 45 minutes. The question types are true/false and single-choice questions, with a full score of 100. Subject 4 consists of 50 questions, each worth 2 points, with a test time of 45 minutes. The questions are mainly in the form of case studies, pictures, animations, etc., and the question types include true/false, single-choice, and multiple-choice questions, with a full score of 100. Exam content focus: Subject 1 mainly assesses basic knowledge of road driving, while Subject 4 focuses on safe and civilized driving knowledge. It can be understood this way: Subject 1 tests how to drive, while Subject 4 tests how to drive safely. Although the difference is just two words (safety), the focus is completely different. Proportion of exam content: Subject 1 exam content composition: Driving license and motor vehicle management regulations account for 20%; Road traffic conditions and regulations account for 25%; Road traffic safety violations and penalties account for 25%; Road traffic accident handling regulations account for 10%; Basic knowledge of motor vehicles accounts for 10%; Local regulations account for 10%. Subject 4 exam content composition: Safe driving knowledge accounts for 20%; Civilized driving knowledge accounts for 18%; Comprehensive application of road traffic signals in traffic scenarios accounts for 8%; Safe driving knowledge under adverse weather and complex road conditions accounts for 16%; Emergency avoidance knowledge accounts for 12%; Typical accident case analysis accounts for 6%; Traffic accident rescue and common hazardous chemical disposal knowledge accounts for 10%; Local test questions account for 10%. There is no limit to the number of attempts for driving test Subject 1 and Subject 4. If the test is failed, it can be rescheduled. Each scheduled test has two attempts. If both attempts are failed, the test can only be retaken until it is passed. Both Subject 1 and Subject 4 are theoretical tests and are part of the motor vehicle driving license assessment. There are a total of 3 subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. In the official terminology (i.e., the Ministry of Public Security Order No. 123), there is no such term as Subject 4.

The exam content for Subject 1 includes basic knowledge such as traffic laws and regulations, traffic signals, and driving safety, which serves as the theoretical foundation for obtaining a driver's license. I was first exposed to this part when learning to drive. The exam questions are all single-choice and true/false, relatively straightforward, testing the memorization of basic rules. Subject 4, on the other hand, is the safe and civilized driving test, which is actually closer to complex scenarios encountered in real road conditions. The questions are mostly case analyses and situational simulations, testing your ability to make flexible judgments in various situations, such as how to react when encountering pedestrians. Failing Subject 1 means you can't start practical driving lessons, while Subject 4 is the final step before obtaining the driver's license, with more practical question types that focus on details often overlooked in actual driving.

What is the average fuel consumption of large-displacement motorcycles?

400CC: around 4.5 liters, 500CC and above: around 5 liters, 750CC and above: around 6 liters. Displacement and Fuel Consumption: Generally speaking, the larger the displacement of a motor vehicle, the higher the fuel consumption per kilometer. However, due to factors such as vehicle type, engine, and other internal and external influences, there is no standard formula between displacement and fuel consumption. Weight and Fuel Consumption: For the same displacement, vehicles with different total weights will have different fuel consumption; lighter vehicles are more fuel-efficient. Similarly, for the same displacement, tires with different widths will affect fuel consumption; narrower tires are more fuel-efficient.

Is It Safe to Store Iwatani Gas Canisters in a Car?

It is unsafe to store portable stove gas canisters in a car. These canisters contain flammable and explosive fuel, with instructions specifying that storage temperatures should not exceed 40°C. During summer, temperatures inside a vehicle can exceed 60°C, which may easily cause the gas canisters to explode or combust. Safety Precautions for Portable Stove Gas Canisters: Definition of Portable Stove: Portable stoves, also known as butane gas stoves, are non-fixed cooking appliances that primarily use butane gas as fuel (liquefied petroleum gas can also be used) and employ direct flame heating. They are commonly used for outdoor family recreation and as hotel supplies. Pressure Sensing Mechanism: Most portable stoves utilize a pressure-sensing system via a regulating valve that monitors pressure in both the valve body and gas canister. The system triggers corresponding actions by the anti-explosion rod inside the regulating valve when pressure fluctuates. Without this pressure-regulating and explosion-proof device, excessive pressure in the canister and valve could lead to explosions. When equipped with safety mechanisms, the anti-explosion rod will activate under high-pressure conditions by either engaging the canister lever or cutting off the gas inlet/outlet to isolate gas flow, thereby preventing further pressure buildup and potential hazards.

What Are the Effects of Extremely Cold Weather on New Energy Vehicles?

New energy vehicles may experience different situations depending on the type of model. Here are the main effects: Reduced Driving Range: Both plug-in hybrids and pure electric vehicles are affected. Due to the chemical properties of their power batteries, when the temperature drops below 0 degrees Celsius, their pure electric driving range will decrease to varying degrees. Decline in Acceleration Performance: With the rapid reduction in driving range and the impact of extreme cold, battery performance significantly decreases, and the discharge power weakens. This places an even heavier burden on electric vehicles, which are already limited in mobility, leading to a notable decline in acceleration performance during winter. Charging Difficulties: Due to the influence of low winter temperatures on charging current and speed, charging times become longer.

What Causes the Engine Malfunction Light to Flash Suddenly?

When the vehicle's power is turned on but the engine is not yet started, various malfunction indicator lights on the dashboard—including those for the engine, coolant temperature, battery, and airbag—will illuminate simultaneously. These lights will automatically turn off once the vehicle is started, which is part of the vehicle's self-diagnostic function and is considered normal. Three scenarios after the engine malfunction light flashes: Vehicle fails to start: This could be caused by a faulty fuel pump or ignition components. In this case, it is advisable to call for roadside assistance immediately. Malfunction light remains on: If the vehicle drives normally without any noticeable issues, the problem might be a faulty sensor. You can continue driving temporarily, but it is recommended to drive at low to moderate speeds and head to a repair shop as soon as possible. Engine malfunction light illuminates: If the vehicle can still be driven but exhibits severe shaking, lack of power during acceleration, or other concerning symptoms, it is best to pull over safely and call for emergency assistance.
