With respect to tour bus operators, the DGH proposed that, starting in 2007, tour buses exceeding 12 years of age will be forcibly withdrawn from general service, and special license plates will be issued restricting them to fixed routes and forbidding them from serving mountainous areas. Furthermore, tour bus operators will be required to display each vehicle's date of manufacture prominently on its body, for consumers 'information.
關於遊覽車業者，公路總局則研擬，2007 年起車齡超過 12 年的遊覽車一律強制退場、改換發僅能行駛固定路線的交通車牌照，並且禁行山區；此外，還將強制遊覽車在車身明顯部位標示出廠時間，以方便消費者辨識。
