语法上没错,只是个人觉得the significance of traffic rules作为短语,并不算长,放bring后面好些,只是建议.
We should bring the significance of traffic rules home to those who violate traffic regulations.
建议,不要为了用高级句型而用句型,不妨看看下面的句子也还可以
we should let those who violate trafic rules know the significance/importance of obeying traffic rules.
