FASTag is a mandatory electronic toll payment system in India that allows automatic toll deduction when a vehicle passes through toll plazas. It is directly linked to your bank account or prepaid wallet.
If you sell your car, transfer ownership, or your vehicle is lost or stolen,How to Block FASTag immediately is extremely important.
Why blocking FASTag matters
If FASTag is not blocked:
- Toll charges continue to get deducted
