B2 What equipment do you use in rainy and foggy weather?

B2 is easy to hang on rainy days, because if it rains heavily, you even have to close the window. Once the window is closed, the water droplets on the left and right rearview mirrors will naturally cause misjudgment. The misjudgment here refers to our human error, because the lines on the ground and in the corner of the warehouse make it difficult for you to judge whether you are in the right place, so it is easy to fail, which is why you often fail in the exam in the rain.

According to the survey, if ten people take the exam in heavy rain, almost half will fail because of the weather. This data can only be said to be low or high, which is no exaggeration!
