Hi John, thank you for your question. A Z10 classification is for sedans and a Z11 classification is for SUVs and MPVs. If you intend to use your vehicle as a private hire car, you have to convert it to a Z10/Z11 classification. The conversion can be done easily at ONE MOTORING: https://onemotoring.lta.gov.sg/content/onemotoring/home.html and an administrative fee of $100 is applicable.
