Yonhap A union of private taxi drivers said Sunday they will conduct a comprehensive inspection on cabs that are outdated , smelly and unsanitary . A union of independent taxis in Seoul City said it would survey a total of 16 , 200 member cabs running in the capital . Those to be effected have been in use for at least four years and six months . Each owner of an applicable taxi has been informed . The survey will be conducted at six designated gas stations with a team of four inspectors to examine the interior and exterior of the vehicles . Points for review will include whether the cabs wreak of smoke or other musty smells such as from poor maintenance of air conditioning filters . They will also look at the sanitary level of the car seat covers and mats . The level of uncleanliness will be graded good , fair or poor . Those with poor grades will immediately undergo cleaning at the site , replacing the seats and mats and using antibacterial steam cleaners . Those with fair grades will be cleaned with antibacterial deodorizers as well . The inspection will also look into whether there are any illegal advertisements stuck in or on the outside of the taxis , and whether the signs and security lights installed inside the cabs work properly . “ The inspection will be completed on older cabs before being applying to all 50 , 000 cabs belonging to the union by October , in order to provide safer and more pleasant service for the citizens , ” the union said .
