How many days after passing Subject 3 can you take Subject 4 without an appointment?

Subject 4 can be taken without an appointment within 7 days after passing Subject 3. As long as the Subject 3 results are uploaded to the vehicle management office database, you can make an appointment, which usually takes about a day. It is recommended to consult your coach as situations vary in different regions. In some cases, after passing Subject 3, you can directly take Subject 4 without an appointment (for the first time), but you must ensure that the Subject 3 results have been uploaded. Additional information: Subject 4 exam period: If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retest on your own, and no retest fee is required. There are no appointment restrictions for the safe and civilized driving theory test, but the driving skill test permit is valid for three years.

How Much Fuel Does Using Air Conditioning Consume?

Under normal circumstances, it consumes an additional 1-1.5 liters per 100 kilometers. For vehicles with larger displacement or more interior space, the consumption is slightly higher, approximately 15%-20% more than when the air conditioning is not in use. It is also related to factors such as the set temperature of the air conditioning, the external temperature, the condition of the vehicle, the condition of the air conditioning unit, and the driving skill. Below is extended information about car air conditioning: Air Conditioning Introduction: The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions. It provides a comfortable riding environment for passengers, reduces travel fatigue, and creates good working conditions for the driver, playing a crucial role in ensuring safe driving. Car Air Conditioning Layout: Different types of air conditioning systems have different layout methods. Currently, integrated heating and cooling air conditioning systems are widely used in passenger cars. The layout involves assembling components such as the evaporator, heater core, centrifugal blower, and control mechanism together, referred to as the air conditioning unit assembly.

What is the combined fuel consumption per 100 kilometers for the Leiling Hybrid?

The Leiling Hybrid currently has 6 models on sale. Among them, the 2022 model - Dual Engine-1.8H-E-CVT Basic Edition, Luxury Edition, Tech Edition, Leading Edition, and Premium Edition are equipped with a 98-horsepower engine, with an NEDC fuel consumption of 4L per 100 kilometers. The 2022 model - Dual Engine-1.8H-E-CVT Sport Edition is also equipped with a 98-horsepower engine, with an NEDC fuel consumption of 4.2L per 100 kilometers. The fuel tank capacity of the Leiling Hybrid is 43L. The distance that can be covered on a full tank of fuel is as follows: For the 2022 model - Dual Engine-1.8H-E-CVT Basic Edition, Luxury Edition, Tech Edition, Leading Edition, and Premium Edition, the distance that can be covered on a full tank is 43/4*100=1075km. For the 2022 model - Dual Engine-1.8H-E-CVT Sport Edition, the distance that can be covered on a full tank is 43/4.2*100=1023km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not vaporize easily during cold starts, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, in low temperatures, the engine computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

Is a Driver's License Required for Electric Motorcycles in Xi'an?

Riding an electric motorcycle requires a driver's license. As of March 2019, some regions have begun implementing this requirement; electric motorcycles require a motorcycle driver's license, and driving without one may result in detention, such as in Maoming, Guangdong. Starting from April 15, 2019, if the vehicle's speed exceeds 25 kilometers per hour, a motorcycle driver's license is required. Additional Information: Speed Regulations: According to the "New National Standard," the design speed of electric bicycles should be controlled within 25 km/h. However, investigations have found that most electric bicycles currently on the market can reach maximum speeds of 40~50 km/h.

Will points be deducted for gear shifting mistakes in Subject 2?

No points will be deducted. Subject 2 mainly examines the candidate's ability to control the vehicle's position in the field. Generally, shifting to the wrong gear does not result in point deductions. However, if a wrong gear is detected, it is still necessary to promptly shift to the correct gear to avoid affecting the vehicle's performance and, consequently, the operation of the vehicle. Additional information: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and is the abbreviation for the field driving skills test. The test items for cars C1 and C2 include five mandatory tests: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-curves). The total score for the test is 100 points, and a score below 80 points for C1 and C2 tests will be considered a failure.
