Automatic transmission cars typically have 6-7 gears, which are D, P, R, N, S, L, while the M gear is unique to manual-automatic transmission models and is not available in every automatic car. The functions corresponding to each gear are D-Drive (forward gear), P-Park (parking gear), R-Reverse (reverse gear), N-Neutral (neutral gear), S-Sport (sport mode), L-Low (low gear), and M-Manual (manual mode). D-Drive (Drive) is the most commonly used gear, where gear shifting is controlled by the accelerator. D1 (or L gear), D2, and D3 are equivalent to gears 1 and 2, 3 and 4, and 5 and 6 in a manual transmission. L-Low (Low) is used when descending a slope to reduce brake usage, and when ascending a slope to provide more power for climbing. R-Reverse (Reverse) can only be engaged when the vehicle is stationary. Some models with a lock button require pressing the button to switch to this gear. N-Neutral (Neutral) is used for temporary stops, such as at traffic lights, and the handbrake should be engaged. It should not be used when descending a slope. S-Sport (Sport) differs from D only in that the computer switches to a different shifting program, so S can be engaged at any time without damaging the transmission. It is suitable for overtaking but not for high-speed driving. M-Manual (Manual) is unique to manual-automatic transmission models, allowing the driver to enjoy manual shifting. The "+" sign indicates upshifting, while the "-" sign indicates downshifting. P-Park (Parking) is sometimes separated as an electronic brake in some models, though the principle remains the same.

Will driving in a vest result in penalty points?

Driving in a vest generally does not result in penalty points. Here are some driving tips: 1. Slow down and look both ways at intersections: Develop the habit of slowing down and checking left and right when approaching intersections. Observe the traffic conditions on the cross lanes and proceed only when it is clear. Maintaining a calm mindset while driving is crucial—anticipate situations in advance, stay composed, and handle emergencies with ease. 2. Slow down and check carefully when turning: Whether in urban or rural areas, always slow down significantly when turning. Develop the habit of checking bicycle lanes and pedestrian walkways, and actively yield to electric bikes on bicycle lanes and pedestrians on walkways. When making a right turn in the city, always yield to pedestrians and electric bikes, ensuring no accidents occur before proceeding slowly. 3. Maintain a safe following distance: Many traffic accidents are directly related to unsafe following distances. Always pay attention to the distance between vehicles while driving. Reduce speed and use the horn to signal in areas with turns or heavy pedestrian traffic.

Can I Claim Insurance If I Hit a Pole with My Car?

If you have only purchased compulsory traffic accident liability insurance and third-party liability insurance, the insurance company will not compensate for hitting a pole while driving. If you have purchased vehicle damage insurance, you can file a claim with the insurance company for hitting a pole. Compulsory traffic accident liability insurance and third-party liability insurance are both designed to compensate third parties in traffic accidents, so the insurance company will not pay for hitting a pole. Vehicle damage insurance, however, is a commercial insurance that covers the loss or damage to the vehicle itself, making it possible to claim compensation for hitting a pole. According to Article 5 of the "Motor Vehicle Damage Insurance Clause," during the insurance period of the contract, the company is responsible for compensating for the loss of the insured vehicle caused by an accident, as stipulated in the contract. Article 6 states that in the event of an insurance accident, the company is responsible for compensating the necessary and reasonable expenses incurred by the insured for rescue and protection measures taken for the insured vehicle, as stipulated in the contract. Article 7 specifies that the company is not responsible for compensating for the portion that should be covered by other responsible parties in the accident according to the compulsory traffic accident liability insurance contract.

What are the four special designs of a gasoline direct injection engine?

The four special designs of a gasoline direct injection engine are high-pressure swirl injectors, intake swirl generation devices, special pistons, and electronic throttle control. Below is an introduction to engines: 1. Introduction: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. The first external combustion engine was invented by R. Stirling in the UK (Scotland) in 1816, which was later improved by Watt into the steam engine. 2. Applicability: Engines can refer to both power generation devices and the entire machine including power devices (e.g., gasoline engines, aircraft engines). Their types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), gas turbines (racing cars), electric motors, etc. 3. Development History: Looking back at the history of engine creation and development, it has gone through three stages: steam engines, external combustion engines, and internal combustion engines.

What is the correct sequence of operations for stalling in Subject 3?

Here is the introduction to the correct sequence of operations for stalling in Subject 3: 1. Sequence one: There are two deduction criteria for stalling in Subject 3. One is a direct stall caused by improper operation, which deducts 10 points. The other is a stall caused by a mismatch between the gear and the vehicle speed (usually high gear and low speed), which manifests as a jerking sensation in the vehicle, and this type of stall is considered a failure. The first type of stall is caused by improper use of the clutch, usually lifting it too quickly. 2. Sequence two: The method of using the clutch: When pressing down, it must be pressed all the way to the bottom. During the lifting process, it should be two fast, two slow, and one pause. The total travel of the clutch when lifting is divided into five points (fast-slow-pause-slow-fast). The engagement point of the clutch varies for each vehicle. For beginners, the entire travel should be slower, gradually approaching the correct method of use. 3. Sequence three: During the process of lifting the clutch pedal when starting on a flat road in Subject 3, as soon as the car starts to move, the clutch has entered the engagement point area and must be paused. If lifted further, the vehicle will either jerk or stall. Wait until the car has moved forward more than 2 meters, then slowly lift the clutch pedal completely. This way, the vehicle will not stall when starting.
