How to Disinfect the Interior of a Car?

Detailed methods for disinfecting the interior of a car are as follows: 1. Use an air purifier: An air purifier can, to some extent, prevent certain viruses and particulate matter like dust from entering the car. However, it is important to note that viruses are primarily transmitted through droplets. When coughing, sneezing, or even speaking, droplets are expelled from the mouth and nose. Therefore, relying solely on a car air purifier to filter harmful substances does not completely block viruses. 2. Maintain ventilation: The Chinese Center for Disease Control and Prevention has provided the following recommendations for protecting private cars during the pandemic: in open areas, ensure ventilation and air exchange; in enclosed environments, close the windows and doors while turning on the air conditioning in recirculation mode. However, when opening windows for ventilation in winter, be cautious to prevent unnecessary situations like catching a cold due to significant temperature differences between the inside and outside of the car. 3. Disinfecting wipes: After drivers or passengers return to the car from public places, it is recommended to first use hand sanitizer for hand hygiene. If relatives or friends (with unknown health status) have been in the car, promptly open the windows for ventilation and disinfect the surfaces of relevant objects inside the car. You can choose legally effective disinfectants or disinfecting wipes for wiping and disinfection.

What are the rules for entering a service road from the main road?

Rules for entering a service road from the main road: 1. Use turn signals: When driving on the main road, if approaching a traffic light intersection, you must enter the service road before making a right turn. When merging from the main road into the service road, use your turn signals to inform vehicles behind you that your vehicle intends to change lanes. 2. Observe the situation: Before entering the service road, observe the conditions on the service road to ensure there are no vehicles behind you. Merge slowly, as there may be blind spots in the rearview mirror. If necessary, stop between the main road and the service road to clearly assess the situation before merging to avoid any unexpected incidents. 3. Steer gently: When merging into the service road, avoid turning the steering wheel too sharply. This gives vehicles behind you in the service road time to react. Observe the movement of vehicles going straight on the service road before entering. 4. Follow the correct route: On roads with service lanes, it is often necessary to enter the service lane when making a right turn from the main road. Therefore, while driving, follow the road markings, signs, and indicators to choose the correct lane.

Will the Subject 2 Test Be Cancelled in Heavy Rain?

It depends on the intensity of the rain. Generally, light rain will not affect the test, and only extremely severe weather or torrential downpours will lead to cancellation. Don't panic if you take the test on a rainy day—maintaining composure is most important. Slowing down your speed will give you more time to think and react, and by using the methods taught by your instructor, you can still pass the test with ease. Here are some relevant details: 1. Disadvantages of taking the test on a rainy day: Although rain can make boundary lines and reference points clearer after being washed by the rain, excessive water accumulation can obstruct visibility. Additionally, rainwater on the rearview mirrors and windshield, as well as fogging inside the car, can impair your view. 2. Preparations for a rainy-day test: Wipe the rearview mirrors clean before getting in the car; avoid closing the windows too tightly, as this can cause fogging on the windshield; promptly turn on the wipers and adjust their speed according to the rain intensity to ensure clear visibility; wear anti-slip shoes, as wet soles may cause slipping when pressing the pedals, or dry your soles with a cloth before stepping on the pedals.
