Li Lei’s right leg was hurt. (His classmates had to send him to the hospital.)So it’s very important for us to obey the traffic rules. First, when the lights turn red, we must stop. When the lights turn green, we can cross the road. Second, we shouldn’t ride too fast and we should ride on the right of the road. Third, we should always be careful and wear bicycle helmets when we ride bikes. Fourth, if we break the traffic rules, we’ll get a fine.
