Toll tax for cars in India is collected by NHAI (National Highways Authority of India) at toll plazas on national highways. FASTag is mandatory for all vehicles — cash tolls are 1.5x the FASTag rate, making RFID-based payment the only cost-efficient option. Toll rates for cars (LMV) range from approximately ₹0.50/km on 2-lane highways to ₹1.25/km on 4-lane expressways.

The return trip discount (50% off on the return leg within 24 hours) is automatically applied when using FASTag. This means a ₹340 one-way Delhi-Chandigarh trip costs only ₹510 return with FASTag — a ₹170 saving over two separate one-way cash payments.

FASTag: Mandatory and Essential

Since February 2021, FASTag is mandatory at all NHAI toll plazas. Without FASTag, you pay 1.5x the listed toll rate. With FASTag, you pay the listed rate and save 33%. FASTag can be purchased online (Amazon, Flipkart) or at toll plazas, and is linked to a bank account or prepaid wallet.
