🚗 Why CNG Kit Installation Requires RTO Approval

Compressed Natural Gas (CNG) is an economical and environmentally friendly fuel. Due to rising petrol and diesel prices, many car owners in India are switching to CNG. However, installing a CNG kit without proper RTO approval is illegal and can lead to hefty fines, RC cancellation, or insurance rejection.

Is CNG legal in all states?

Yes, CNG is legal throughout India, but installation must be done only at RTO-approved retrofit centers with proper documentation.
