Car horn sounds are considered noise if they exceed 74 dB. Introduction to Car Horn Sounds: Car horn sounds are a major source of traffic noise pollution, characterized by sudden onset, short duration, and high volume. The horn of a small car can cause instantaneous noise levels to exceed 70 dB and approach 80 dB, while the horn of a large vehicle can exceed 80 dB. Legal Regulations on Noise: The 'Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution' defines environmental noise pollution as noise that exceeds the national environmental noise emission standards and interferes with the normal life, work, and study of others.

Is 20 Minutes of Daily Driving Practice at Driving School Reasonable?

1. Every time you go to the driving school for practice, you have to wait in line for a long time before it's your turn. However, the instructor only allows each person to practice for 20 minutes before switching to the next. Many students complain that the instructor is stingy. In fact, the instructor does this not to save on fuel costs or cut expenses, but for your own good. Only after understanding the reason will you realize the instructor's good intentions. 2. Therefore, everyone should cherish their 20 minutes of practice time. Don't think that the practice time is too short and just go through the motions. You can also observe others' practice to learn from their experiences and enrich your own. Additionally, after practice, you should reflect and summarize your experiences in a timely manner. This way, your driving skills will improve, helping you pass the test smoothly.

Do driving schools usually conduct training on rainy days?

Indeed, driving schools generally do not conduct training on rainy days. However, 'generally' does not mean 'always.' Many driving schools, especially when they have a large number of students and a full schedule, will still arrange training sessions even in the rain. If the driving school or instructor is unwilling to conduct training in the rain, there's not much you can do. But if you're pressed for time and finally have an opportunity, you might try to persuade the instructor. Normally, it is possible to practice for Subject 2 (basic vehicle control) on rainy days. After all, the weather can't always be sunny, and exams proceed as usual even in the rain. Practicing Subject 2 in the rain can help candidates adapt to an additional scenario, making them more comfortable during the exam if it happens to rain.

Are Driving Schools State-Owned or Private?

Both exist. Driving schools are institutions where individuals obtain motor vehicle driver's licenses. They assist students in mastering relevant driving skills and collaborate with vehicle management offices to conduct examinations, serving as training units for acquiring motor vehicle driver's licenses. As part of the transportation industry, they fall under the category of service-oriented training institutions. During the examination period for a motor vehicle driver's license, it is possible to switch driving schools, but only once. After changing driving schools, students must complete all remaining subject examinations at the new institution without further changes. This significantly extends the time required to obtain a motor vehicle driver's license, providing convenience for those taking the driving test while working or studying in a different location.
