What are the differences between the three routes in Subject 3?

The differences between the three routes in Subject 3 lie in the fifth, sixth, seventh, and eighth test items. For Route 1, the fifth item is passing a bus stop; for Route 2, the fifth item is driving straight; and for Route 3, the fifth item is proceeding straight through an intersection. The sixth item for Route 1 is proceeding straight through an intersection; for Route 2, it is gear shifting; and for Route 3, it is passing a school zone. The seventh item for Route 1 is overtaking; for Route 2, it is overtaking; and for Route 3, it is driving straight. The eighth item for Route 1 is gear shifting; for Route 2, it is changing lanes to the left; and for Route 3, it is changing lanes to the left. Subject 3 road test consists of 16 items in total. Candidates need to master preparation before driving, light simulation test, starting, driving straight, gear shifting operation, changing lanes, pulling over, proceeding straight through an intersection, turning left at an intersection, turning right at an intersection, passing a crosswalk, passing a school zone, passing a bus stop, meeting oncoming vehicles, overtaking, making a U-turn, and driving at night. Candidates should pay attention to the penalty items during the test and avoid making mistakes to pass the test smoothly.

Is it okay to lock the car without turning off the air conditioner?

There is a certain impact. If you lock the car without turning off the air conditioner, it should not cause the battery to drain, as the power to the air conditioner is cut off after locking. However, since the air conditioner was not turned off before locking the car, the fan switch remains on. The next time you start the car engine, the fan will start directly. Since the fan draws a large current when starting, it will affect the lifespan of the switch contacts and increase the engine load. Therefore, it is advisable to turn off the air conditioner and fan before locking the car. Here are some precautions for using the car air conditioner: 1. Avoid using the air conditioner for too long in a single session: If the temperature inside the car has reached a comfortable level, you can turn off the air conditioner or turn it on again after a while. Prolonged use of the air conditioner can increase the pressure on the condenser, causing wear and tear on the cooling system. Therefore, it is recommended not to use the air conditioner for extended periods. 2. Ventilate by opening the windows: When you first enter the car, open the windows and turn on the external circulation to expel the hot air. 3. Avoid using the internal circulation mode for too long: Internal circulation recirculates air within the enclosed space of the car, leading to a continuous decrease in oxygen levels. Additionally, if the gasoline in the cylinders does not burn completely, unburned carbon monoxide from the engine may leak into the cabin, deteriorating the air quality inside the car and potentially causing harm to the occupants.

Can the Air Conditioning Be Turned On Without Starting the Engine?

No, the air conditioning cannot be turned on without starting the engine, because the air conditioning compressor cannot operate without the engine running, and thus the air conditioning cannot provide cooling. The car air conditioning cooling system consists of components such as the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These parts are connected by copper pipes and high-pressure rubber hoses to form a sealed system. When the cooling system is in operation, the refrigerant circulates through this sealed system in different states. The process is mainly divided into four stages: compression, heat dissipation, throttling, and heat absorption. The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet, compresses it into high-temperature, high-pressure gas, and discharges it from the compressor. The high-temperature, high-pressure superheated refrigerant gas then enters the condenser, where, due to the reduction in pressure and temperature, it condenses into a liquid and releases a significant amount of heat. The high-temperature, high-pressure refrigerant liquid passes through the expansion device, where its volume increases, and its pressure and temperature drop sharply, exiting the expansion device in a mist-like form. The mist-like refrigerant liquid enters the evaporator, where, because the boiling point of the refrigerant is much lower than the temperature inside the evaporator, it evaporates into a gas. During this evaporation process, it absorbs a large amount of heat from the surroundings, and the resulting low-temperature, low-pressure refrigerant vapor re-enters the compressor. When using the car air conditioning, attention should be paid to the timing of turning the air conditioning on/off, the use of the internal/external air circulation, and the direction of the airflow. It is best to adjust the airflow direction to blow only toward the face, with the air vents positioned horizontally or slightly upward for optimal performance.

Do You Need to Press the Clutch When Turning a Car?

When turning a car, you need to press the clutch. Before turning, you should first press the brake to slow down. If the engine shakes severely, you need to downshift and then press the clutch to change gears. This is because when turning, pressing the brake to slow down is the priority, while pressing the clutch only cuts off the power, but the car still has inertia. Degree of pressing the clutch: When the car speed is slow during a turn but the gear is too high, and the car tends to jerk or stall, you need to press the clutch to downshift. At this time, the clutch must be pressed all the way down; otherwise, it may be difficult to engage the gear or the gear may not stay stable during downshifting. Correct way to press the clutch and brake when turning: Press the brake before turning to slow down in advance, then shift into the appropriate gear based on the size of the curve and the car speed. After entering the curve, press the brake to slow down and press the clutch. After exiting the curve, press the accelerator to speed up. If you press the clutch directly without slowing down, the car will enter a coasting state, or the power will become weak. In case of an emergency, the driver will have to control the steering wheel, pay attention to the speed, and possibly change gears, which can easily lead to confusion. Precautions when turning: When turning a car, you need to control the speed according to the size of the curve. Try to slow down as much as possible to avoid phenomena such as loss of control or skidding. If a skid occurs, immediately release the accelerator pedal and turn the steering wheel toward the side where the rear wheels are skidding. Once the car returns to the normal driving direction, straighten the steering wheel and proceed. When turning, the operation of the steering wheel should match the curvature of the road and coordinate with the car speed, ensuring appropriate steering angle, timely steering, and prompt return of the steering wheel. It is strictly forbidden to take both hands off the steering wheel to prevent deviation and danger.
