近年來我國工商業發展迅速，觀光與交通事業也隨之有長足的發展。工商業進步，促進社會的經濟繁榮，而經濟繁榮導致人貨交流的更大需求，車輛或其他交通工具因之激增。因車輛激增，社會中各行各業對汽車駕駛人員的需求非常殷切。我們熟知駕駛人員是否良好，不僅直接影響行人、乘客及駕駛人自身的生命與財產安全，並且對雇用機關之業務積效、財產安全及經營利潤亦均息息相關。除此之外，更重要者，駕駛人員的工作表現，對於交通秩序之良好與否，對於社會治安有利與否也有密切而不可分的關係。是故如何甄巽稱職的駕駛人，如何淘汰已從事駕駛工作而有肇事傾向的司機，如何了解駕駛人員的機械能力、人格特質、駕駛態度等以預防不幸事件之發生，以及如何提高駕駛人員素質等問題，已是當前工商與交通事業發展過程中極端重要的問題，而迫切需要答案及解決之道。
