As　the　main　artery　of　transportation,　freeway　is　responsible　for　the　operation　of　trucks,　but　these　trucks　have　led　to　an　increase　in　the　appearance　of　debris.　Understanding　the　subjective　cognitive　laws　of　drivers　on　freeway　debris　is　essential　for　freeway　safety　management.　Based　on　questionnaire　data,　this　paper　explores　differences　in　drivers’　perception　of　freeway　debris　through　independent　sample　t-test　and　one-way　ANOVA.　The　results　show　that　drivers　of　different　genders,　driving　ages,　and　driving　styles　are　different　in　their　awareness　and　attention　to　debris.　In　the　early　warning　measures　for　debris,　drivers　prefered　the　navigation　system.　In　the　traffic　management　measures,　drivers　tended　to　choose　to　improve　the　inspection　of　the　binding　goods　for　trucks　at　toll　stations.　This　can　provide　a　basis　for　the　formulation　of　the　management　regulations　of　the　freeway　management　department　on　the　debris.　©　ASCE.
