My name is Tony. I'm a traffic policeman. I'm glad to hear that you are going on an outing tomorrow. For everyone's safety, I'll give you some advice on how stay safe. First of all, you should take care of your own safety. You should always put safety first. Second, you should obey traffic safety rules. Don't cross the road the green light is on. Some of you like to go hiking bike. Don't forget to wear helmets when you ride your bike. You need to ride the right. If there is traffic accident, remember to call the accident telephone for help. Finally, you should care for each other and help each other. I hope you will have a good trip. Thank you.
