One possible version：obeying_the_traffic_rules.
Nowadays，as the number of vehicles is increasing on the road，traffic problems have become part of our life.Some people run the red light at the crossing and others ride their bikes on the roadway.Some drivers drive too fast in the street.All the behavior presents potential danger.If we don’t obey the traffic rules，there might be more traffic jams and accidents.
To keep the traffic smooth，I suggest all the students should obey the traffic rules when walking in the street to make sure we are safe and avoid trouble.Also，I think it is necessary to lay stress on the traffic safety education.
Let’s take responsibility for ourselves and others.Let’s take action now!
