How to judge if the car is parked in the middle of the road at the entrance of an S-curve?

Drivers can generally judge if the car is parked in the middle of the road by aligning themselves with the center of the S-curve entrance. Below are the contents of the Subject 2 driving test: 1. Parallel parking; 2. Stopping at a designated point and starting on a slope; 3. Reversing into a parking space; 4. Driving through curves; 5. Turning at a right angle. Here is some additional information: 1. Materials required for Subject 2: ID card, exam admission ticket, etc. Before the test, check if all items are prepared, as missing any may affect the exam. 2. Subject 2 retake rules: Subject 2 allows up to five retakes. If the fifth attempt is still unsuccessful, the results of other previously passed subjects will be invalidated, and you will need to start over from Subject 1. Each Subject 2 exam appointment includes two attempts. If the first attempt fails, you can retake it once for free. If you do not take the retake or fail the retake, the exam ends, and you can reschedule the Subject 2 test after ten days.

What are the policies for new energy vehicles?

New energy vehicle policies: 1. "2021 Industrial and Information Technology Standardization Work Priorities": The document mentions the need to vigorously conduct research and formulation of standards for electric vehicles, charging and swapping systems, fuel cell vehicles, etc.; promote the development of related standards for power battery recycling; and revise the guidelines or roadmaps for the standard system construction of electric vehicles, lithium-ion batteries, etc., based on the needs of technological progress and rapid industrial development and integration. 2. "Implementation Plan for Accelerating the Cultivation of New Consumption": The plan proposes to improve the configuration and layout of charging power sources and increase the construction of charging piles (stations) to meet the demand for new energy vehicles and delivery logistics vehicles. It also encourages charging pile operators to appropriately reduce charging service fees. 3. "2021 Energy Work Guidance": The guidance points out that, following the "source-grid-load-storage integration" approach, efforts should be made to continuously advance the construction of urban smart grids, promote the high-quality development of urban electric vehicle charging and swapping infrastructure, accelerate the promotion of interactive power supply and demand systems, and adapt to the diversified access needs of high-proportion renewable energy and electric vehicles.

What temperature should the car air conditioner be set at in summer?

In summer, the temperature inside the car should not be set too low. Generally, setting it at 26°C is optimal, and maintaining a temperature difference within 10°C between the inside and outside of the car is the healthiest. Below is additional information: 1. Car Air Conditioner: A car air conditioner refers to the air conditioning device installed in a vehicle, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The air conditioning system has become one of the indicators of a car's comprehensive functionality. It generally includes cooling, heating, and ventilation devices. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally. 2. Working Principle: When the cooling system operates, the refrigerant circulates in different states within this closed system, with each cycle consisting of four basic processes: compression, heat dissipation, throttling, and heat absorption. During the evaporation process, it absorbs a large amount of surrounding heat, after which the low-temperature, low-pressure refrigerant vapor re-enters the compressor. These processes repeat continuously to achieve the reduction of air temperature around the evaporator.

Which light must be turned on to alert vehicles and pedestrians in foggy conditions?

Fog lights must be turned on when driving in foggy conditions. Below are the usage guidelines for car light signals: 1. Overtaking or when the vehicle ahead doesn't move after the traffic light turns green: Corresponding light signal: Flash the headlights once or twice. When waiting at an intersection, if the vehicle ahead doesn't move after the light turns green, the vehicle behind usually takes some action to give a hint. You can flash the headlights once or twice to remind the driver ahead, but avoid doing it too frequently. The same applies when overtaking—appropriately flash the headlights once or twice to alert the driver ahead to yield or pay attention. 2. Encountering blinding high beams during nighttime driving: Corresponding light signal: Flash the headlights twice. With technological advancements, more and more vehicles on the road are equipped with xenon headlights. Flash the headlights twice from a distance to remind the oncoming vehicle to switch to low beams when passing. If there's no response to the flashing, you can also briefly turn on the high beams and then quickly turn them off to remind the other driver to adjust their lights. 3. Alerting another driver to your vehicle's condition: Corresponding light signal: Flash the headlights three times, accompanied by a horn. While driving, if you notice that the vehicle ahead has an unclosed door or significantly underinflated tires, you can flash the headlights three times in succession. Once the driver ahead notices the lights, flash them three more times.
