A warning sentence needs to be added. In China, the Road Traffic Safety Law stipulates that you are not allowed to use mobile phones while driving a motor vehicle, and you are not allowed to publish text, pictures, audio and video and other information while driving a motor vehicle through information networks. When posting driving videos on Douyin, there are cases where mobile phones are used, so it is necessary to add similar warnings such as "Please do not imitate, pay attention to safety" at the beginning or end of the video to remind people watching the video to pay attention to traffic safety and not to imitate. .
