Firstly, swimming alone in the river is also very dangerous, especially for students. Accidents are unpredictable and no one will help or even know if they are alone.
Furthermore, it is important for students to be careful while on their way to and from school. As the traffic becomes busy, students have to be alert while using the roads and follow the traffic instructions.
Lastly, student can always tell their teacher or contact the local police whenever they are in problem. With that, they can get help as soon as possible and assure their safety.
