If you wish to purchase a new CNG vehicle, you may approach the dealer of that vehicle to make the necessary arrangement with any of the above-mentioned CNG system suppliers for a suitable CNG conversion kit to be installed onto your vehicle.

Following this, the vehicle dealer can proceed to submit an application via VITAS (Vehicle Inspection and Type Approval System) with the relevant documentation and certification.

If the requirements are complied with, we would give an in-principle approval letter to the vehicle dealer (the applicant) to proceed with the inspection at any of the LTA-authorised vehicle inspection centres. This is to check that the vehicle is still roadworthy after the conversion. The converted CNG vehicle is required to pass this inspection.

If you wish to convert your vehicle to be able to operate on CNG, you may approach any LTA-approved CNG system supplier to assess whether the CNG conversion kit that they are providing is suitable for your vehicle. Should you decide to have a CNG conversion kit installed onto your vehicle upon such assessment, the CNG system supplier will then proceed to submit an application via VITAS with the relevant document and information to LTA for assessment.

If the requirements are complied with, we would give an in-principle approval letter to the CNG system supplier (the applicant) to proceed with the inspection at any of the LTA-authorised vehicle inspection centres. This is to check that the vehicle is still roadworthy after the conversion. The converted CNG vehicle is required to pass this inspection.
