What is the sign of low engine oil in a car?

When a car is low on engine oil, the warning light resembles a teapot and illuminates in yellow. Below are some related explanations about engine oil: 1. Insufficient oil level: The most common reason for the engine oil light flashing is a low oil level in the car. In this case, you need to add engine oil. 2. Overheated engine: Another possible cause is an overheated engine. Prolonged driving can lead to excessive engine temperatures, which may thin out the oil. 3. Damaged components: If parts related to the engine oil system are damaged, the oil light may flicker, potentially causing the car to malfunction. The quality of the oil also affects the car's performance. If the oil used is of poor quality, it may contain more impurities, negatively impacting the car's operation.

Should motor vehicles slow down after entering a sharp curve?

Motor vehicles should slow down after entering a sharp curve; otherwise, excessive speed may lead to accidents. The following are legal regulations regarding driving at intersections: 1. When motor vehicles pass through intersections controlled by traffic signals: At intersections with designated lanes, vehicles should enter the appropriate lane based on their intended direction; vehicles preparing to enter a roundabout must yield to vehicles already in the roundabout; when turning left, vehicles should turn from the left side of the intersection center. Turn signals must be activated when turning, and low beams must be used when driving at night. 2. At intersections without directional signal lights: Turning motor vehicles must yield to straight-moving vehicles and pedestrians. Right-turning vehicles from opposite directions must yield to left-turning vehicles.

What does incorrect driving posture in Subject 3 mean?

Subject 3 incorrect driving posture may occur due to the following reasons: 1. Delayed throttle application: After starting, it's essential to master the technique of gently releasing the clutch and applying the throttle according to speed for gear shifting. If throttle application is delayed at this stage, the system will judge it as "incorrect driving posture". 2. Wrong gear selection: Many examinees mistakenly select wrong gears due to nervousness during tests. However, selecting wrong gears in Subject 3 examination will trigger a "speed-gear mismatch" warning. High gear with low speed may cause engine stalling, naturally resulting in test failure. 3. Looking down while shifting: Subject 3 examination explicitly prohibits looking down at the gear lever during gear shifting.

What are the reasons for the headlights of Lavida not working?

Reasons for the headlights of Lavida not working: 1. Severe battery depletion. 2. Overheating of wires leading to increased resistance in the circuit, resulting in reduced brightness of the headlights. In severe cases, the headlight circuit may short-circuit due to the melting of the wire insulation, potentially causing circuit damage or even a vehicle fire. 3. Contacts in the circuit, such as those in the light relay or combination switch, may become corroded or stuck, preventing the circuit from opening or closing properly. 4. The fuse in the headlight circuit may blow, leaving the front of the car in darkness. 5. When using multiple electrical devices for an extended period, the generator may become overloaded, potentially burning out the diodes and coils, leading to generator failure.

Is it a failure if the car body sweeps the line during a right-angle turn?

During right-angle and curve tests, sweeping the line with the car body does not result in point deduction. Additional information: 1. Test requirements: a) During curve driving: If the vehicle crosses the edge line during curve driving assessment, it is considered a failure. b) Right-angle turn: If the wheels touch or press against the protruding point during a right-angle turn, it is considered a failure. 2. The main objectives of Subject 2 test: To master the basic driving operation essentials and possess fundamental vehicle control capabilities; To proficiently master the basic methods of driving on designated areas and internal roads, and have the ability to reasonably use vehicle control components and correctly control the spatial position of the vehicle movement, accurately controlling the vehicle's driving position, speed, and route.

What are the main items tested in vehicle exhaust emissions?

Vehicle exhaust emissions testing primarily examines carbon monoxide, nitrogen oxides, hydrocarbons, photochemical oxidants, and smoke density. The following are reasons for excessive vehicle exhaust emissions: 1. Aging of vehicle components: Due to prolonged use, various parts may deteriorate, leading to noticeably reduced performance and differences in exhaust emissions compared to before. Additionally, older vehicles may have been manufactured using processes that met standards at the time but now fall short due to advancements in production technology and stricter emission regulations, making them more prone to exceeding emission limits. 2. Poor fuel quality: The quality of fuel also impacts vehicle exhaust emissions. Imported vehicles, especially high-end models, often require higher-quality fuel. However, fuel quality in some remote areas of the country may not meet the necessary standards. Long-term use of substandard fuel can easily result in excessive emissions, leading to failure in annual vehicle inspections.
