Do Automatic Transmission Cars Need to Shift Gears?

Automatic transmission vehicles do not require gear shifting during normal driving. However, gear shifting is necessary in the following situations: when accelerating to overtake, controlling speed downhill, or driving uphill. When accelerating to overtake: The D gear may feel sluggish when rapid acceleration is needed for overtaking. In such cases, using manual mode or the S gear mode can provide stronger power. When controlling speed downhill: In D gear, the vehicle may accelerate due to gravity. To counter this, manually shift or use the S gear to lock into a lower gear using the "+-" buttons, enabling engine braking to reduce speed. When driving uphill: Since the D gear shifts at lower RPMs (around 2000 RPM), it may lack sufficient power for steep inclines. Using manual mode or the S gear to lock into first or second gear can provide higher torque for climbing and prevent the vehicle from rolling back. Precautions when shifting gears in automatic transmission cars: Avoid keeping the car in D gear during prolonged stops: During traffic jams or at red lights, many drivers prefer to keep the gear lever in D while pressing the brake pedal. While this is acceptable for short durations, it is advisable to shift to N gear and engage the parking brake for extended stops. Keeping the gear in D while stationary causes slight forward movement in automatic transmission cars. Prolonged braking to counteract this movement can raise transmission fluid temperature, leading to fluid degradation, especially when the air conditioning is on and the engine is idling at higher RPMs. Avoid coasting in neutral while driving: Do not shift to neutral while coasting, as the engine operates at idle speed in this mode. This reduces oil pump supply to the transmission, while transmission components and gears continue to rotate at high speeds during coasting, potentially causing overheating and transmission damage. Shifting to N gear when coasting to a stop at low speeds is acceptable and has no adverse effects.

What is the maximum number of participants for Subject 2 exam?

Generally, there is no maximum limit for the number of participants in the Subject 2 exam. If there are too many applicants, the specific number will depend on the quota released by the vehicle management office and the scale of the examination site. Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the field driving skills test. For small vehicles C1 and C2, the test items include five compulsory subjects: 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). Some regions also include a sixth item: highway card collection. For large vehicles A1, A2, A3, B1, and B2, the test items include: pole test, stopping and starting on a slope, parallel parking, driving over a single-plank bridge, driving through curves, turning at a right angle, passing through a narrow gate, driving over continuous obstacles, driving on bumpy roads, making a U-turn on a narrow road, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rainy (foggy) weather, slippery roads, and emergency handling. The full score is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The exam is considered passed if the following conditions are met: For large passenger cars, tractors, city buses, medium-sized passenger cars, and large trucks, a score of 90 points or above is required. For other vehicle types, a score of 80 points or above is required. For large passenger cars, tractors, city buses, medium-sized passenger cars, and large trucks, a score of 90 points or above is required. For other vehicle types, a score of 80 points or above is required.

What are the consequences of hitting someone else's car and leaving the scene?

Hitting someone else's car and leaving the scene is considered a hit-and-run. If the other party reports it to the police, authorities will retrieve information to contact the offending vehicle. The following are the specific consequences: 1. If it does not constitute a crime: According to Article 13 of the "Measures for Quick Handling of Motor Vehicle Traffic Accidents (Trial)", for hit-and-run cases, the traffic management department of the public security authority will impose a fine on the driver, along with administrative detention of up to 15 days and a 12-point penalty on the driver's license. Additionally, insurance companies are required to increase the insurance premium for the fleeing vehicle the following year. 2. If it constitutes a crime: According to Article 101 of the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China", if a serious traffic accident occurs due to violation of road traffic safety laws and regulations, constituting a crime, criminal responsibility shall be pursued, and the traffic management department of the public security authority will revoke the motor vehicle driver's license.

Can a Five-Seater Modified to a Four-Seater Pass the Annual Inspection?

A five-seater modified to a four-seater cannot pass the annual inspection. The reason is that it alters the vehicle's structure. Below is a detailed introduction about the annual vehicle inspection: 1. Overview: The annual vehicle inspection refers to the annual examination of vehicles that have obtained official license plates and registration certificates, conducted in accordance with the "Technical Conditions for Motor Vehicle Operation Safety." The purpose is to check the main technical conditions of the vehicle, encourage enhanced maintenance, ensure the vehicle is always in good condition, and guarantee driving safety. 2. Others: For passenger vehicles used for commercial purposes, the inspection is conducted once a year within the first 5 years. After 5 years, it is conducted every 6 months. For trucks and large or medium-sized non-commercial passenger vehicles, the inspection is conducted once a year within the first 10 years. After 10 years, it is conducted every 6 months. The annual inspection of motor vehicles is divided into the initial inspection and regular inspections.

Will the car move if the handbrake is not pulled after turning off the engine?

After turning off the engine, the car may move if the handbrake is not pulled. It is essential to engage the handbrake after shutting down the engine. Proper use of the car's braking system is crucial during vehicle operation. Below is a detailed introduction to automobile brakes: 1. Brakes: Brakes, also known as the braking system, refer to the mechanism that stops or reduces the speed of moving locomotives, vehicles, other transportation tools, or machinery. The braking device is a mechanical system designed to slow down the vehicle's speed, also referred to as a decelerator. 2. Braking System: The braking system consists of the control system, hydraulic system, and power assist system. The control system includes components like the pedal and handbrake. The hydraulic system comprises hydraulic fluid, the brake pump, and hydraulic lines. The power assist system includes the vacuum booster pump. The electronic control system consists of the ABS pump, ABS sensors, and ABS computer. The execution system is made up of the brake caliper, brake pads, and brake disc.

What are the reasons for the brake light staying on after the engine is turned off?

After the engine is turned off, the brake light staying on is related to a faulty brake switch or a short circuit in the wiring. The specific reasons are as follows: Faulty Brake Switch: Manually replace the brake switch. Short Circuit in Wiring: Lack of brake fluid: Brake fluid plays a crucial role in the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders located at each wheel, causing the brake pads to contact the wheels and stop the vehicle. Damaged tail light bulb: The brake fluid reservoir has upper and lower lines. If the brake fluid level falls below the lower line, the sensor next to the reservoir will detect this and reflect it through the brake light on the dashboard. If the brake fluid level drops rapidly, it indicates a leak in the braking system. Brake pads need replacement: Note that if the parking brake is not released while driving, the light will also stay on. Therefore, first check whether the parking brake is released.
