Hi Jolene Poh! Same way you converted it into a Z10/Z11 change it to a P10/P11. To convert your vehicle out of the chauffeured Private Hire Car (PHC) scheme, please login to https://onemotoring.lta.gov.sg/content/onemotoring/home.html > Digital Services > Convert Vehicle Type or Scheme and complete the conversion. There will be a $100 administrative fee for the conversion. Then after you get a normal car insurance.
