Remind yourself to be a qualified driver. Freshmen must participate in warning oath education activities before taking the "Civilization Test" (subject 4), because drivers are high-risk occupations, and if they are not careful, they will not only endanger themselves, but also endanger the safety of others. The oath is to remind myself to be a qualified driver. Otherwise, you can't take the subject four exam, which avoids the form and formality of each driving school.
