Subject 3 lighting simulation mnemonic is as follows: High beam: When driving on roads with low visibility, use the high beam correctly. On poorly lit or unlit road sections, the high beam can be used. Alternating high and low beams: When passing sharp curves, slopes, arched bridges, or crosswalks at night, alternate between high and low beams no less than 2 times. When passing intersections without traffic signals at night, alternate between high and low beams no less than 2 times. When overtaking vehicles ahead at night, alternate between high and low beams no less than 2 times. Position lights and hazard warning lights: For temporary parking on the roadside, use position lights + hazard warning lights. In case of vehicle malfunction that obstructs traffic and is difficult to move, use position lights + hazard warning lights.

I remember when preparing for the lighting section of Subject 3, the most effective trick was this rhyme: 'Start with high beams then switch to low, toggle between them when meeting a car, use high beams for night driving, turn on fog lights in rain or fog.' During practice, I recited it repeatedly and found it super practical, especially when simulating night-time car encounters—I nailed it as soon as the examiner gave the command. Lighting operations are no joke; messing up means instant failure and compromises safety, like blinding other drivers by forgetting to turn off high beams. I advise learners to practice night driving more, familiarize themselves with light switch positions, and execute actions swiftly and precisely—no hesitation. Exam mindset matters too; stay calm to avoid mistakes. The rhyme became my lifeline—I passed in one go. Sharing this with friends preparing for the test!

Should You Press the Clutch When Starting the Car?

Starting the car requires pressing the clutch. Pressing the clutch first when starting ensures a smooth take-off. After the engine is started and before the car begins to move, the driver should first press the clutch pedal to disengage the clutch, separating the engine from the drivetrain. Then, the gear is engaged, and the clutch pedal is gradually released to allow the car to start smoothly. Below are some relevant details: 1. Before starting the car, the engine must naturally be started first. When the car begins to move, it accelerates gradually from a complete standstill. If the drivetrain (which connects the entire car) is rigidly linked to the engine, engaging the gear will cause the car to jerk forward suddenly but not actually start moving. 2. This is because the car has significant inertia when transitioning from a standstill to moving forward, creating a substantial resistance torque on the engine. Under the effect of this inertial resistance torque, the engine's speed drops sharply below the minimum stable speed (generally 300-500 RPM), causing the engine to stall and stop working. Consequently, the car cannot start moving, which is why the clutch is necessary. 3. After the engine is started and before the car begins to move, the driver should press the clutch pedal to disengage the clutch, separating the engine from the drivetrain. Then, the gear is engaged, and the clutch pedal is gradually released to allow the clutch to engage progressively. During this process, the resistance torque on the engine increases gradually, so the accelerator pedal should be pressed simultaneously to gradually increase the fuel supply to the engine. This ensures the engine's speed remains at the minimum stable level, preventing stalling. 4. At the same time, as the clutch engagement tightens progressively, the torque transmitted from the engine to the driving wheels through the drivetrain increases gradually. Once the traction force is sufficient to overcome the starting resistance, the car begins to move from a standstill and accelerates smoothly.

What does the driving license test subject 2 include?

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. For small vehicles C1 and C2, the test items include five mandatory tests: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curve (commonly known as the S-curve). In some regions, there is also a sixth item: highway toll card collection. Teaching objectives: Master the essentials: grasp the basic driving operation essentials and possess the basic ability to control the vehicle; Develop skills: proficiently master the basic methods of field and road driving, have the ability to reasonably use vehicle control components and correctly control the spatial position of the vehicle, and be able to accurately control the vehicle's driving position, speed, and route.

Can I Pick Up My Car on the Same Day After Painting?

Whether you can pick up your car the same day after bodywork and painting depends on the size of the painted area. If the painted area is small, you can usually pick up the car the same day, but the paint needs time to dry completely. Differences in bodywork painting: Bodywork painting can be divided into paint and powder. Powder coating dries relatively quickly, especially in a drying oven, while paint, being a liquid, dries more slowly. Paint thickness: The drying time depends on the thickness of the paint and the degree of atomization. Thicker paint takes longer to dry in an oven, and even longer if left to dry naturally—possibly up to a week. Weather conditions: Sufficient light is required when mixing paint to avoid color discrepancies, so paint cannot be mixed on cloudy days.

What is the fuel consumption per 100 kilometers for a 125cc scooter?

Scooter 125cc fuel consumption per 100 kilometers ranges between 1.5L-2.0L. Here is some relevant information about scooters: 1. Overview: Scooters are basically continuously variable transmission with automatic clutch, similar to electric mopeds, without gear design. After starting, you only need to twist the throttle to go, and releasing the throttle will automatically slow down until stopping. Moreover, the wheels of scooters are smaller than other motorcycles, and the transmission part is mostly belt-driven, which is commonly known as a step-through motorcycle. The term "scooter" refers to the wide footboard between the seat and the handlebars, allowing riders to comfortably place their feet on it, just like sitting on a chair, without having to straddle the bike as with other motorcycles. 2. Methods to reduce fuel consumption: (1) Maintain normal cylinder pressure: Cylinder pressure is closely related to the sealing performance of the cylinder. If the cylinder pressure is below 50% of the standard value of 165350, it must be repaired in time, otherwise it will increase fuel consumption. (2) Choose high-quality tires: Tires with good wear resistance are a good choice, and since scooters have a lower chassis, tires are crucial.

Can You Still Drive with an Engine Control System Malfunction?

You can continue driving. Vehicles are designed with emergency measures for the engine system. If this warning light is on, you should avoid driving too fast. Over time, emission control may stop functioning properly, and fuel efficiency may decrease, but this does not significantly affect the control system. As long as you drive slowly, there should be no major issues. Below is an introduction to the engine control system: Control Computer: The ECU is the engine's control computer, often referred to as the brain of the engine. Without the ECU, the car's engine cannot operate normally. Causes of ECU Damage: There are many factors that can lead to ECU damage, such as power circuit faults, output power module failures, memory faults, ECU water ingress, or moisture exposure. Electronic Control Unit: The ECU, or Electronic Control Unit, is essentially a dedicated automotive microcomputer controller. It consists of a microprocessor, memory, input/output interfaces, analog-to-digital converters, and large-scale integrated circuits for shaping and driving.

What's the Difference Between Full Synthetic Oil and Mineral Oil?

The biggest differences between the two are: synthetic oil has a wider temperature range, a longer service life, and higher costs. For the same oil film requirements, synthetic oil can achieve this with a lower viscosity, whereas mineral oil requires a relatively thicker viscosity to meet the same requirements. Below are the relevant introductions: 1. Mineral Oil Mineral oil is the residue left after gasoline and heavy oil are refined from petroleum. Mineral oil is actually a natural oil with more impurities. It is cheaper compared to semi-synthetic and full synthetic oils but provides poorer lubrication for the engine and has a shorter service life. If a car uses mineral oil, it is recommended to change the oil every 5,000 kilometers for better engine performance. 2. Full Synthetic Oil: This is the highest quality and most durable type of oil, and also the most expensive. Generally, it can last for 10,000-12,000 kilometers in a typical car without deteriorating. However, for safety reasons, it is recommended to change full synthetic oil every 10,000 kilometers or within 8 months, whichever comes first, unless under special circumstances.
