What it means
A conventional toll plaza has lanes, booths and barriers, so every vehicle slows down or stops. MLFF removes the barriers. Gantry-mounted FASTag readers detect the tag, and ANPR cameras read the plate. The plate read matters most when a tag is missing, invalid or has no balance, because the plate is then the only way to identify the vehicle and its owner.
How it applies in India
NHAI launched India's first MLFF tolling system at the Chorayasi Toll Plaza on the Surat-Bharuch section of NH-48 in Gujarat. PIB reported on 2 May 2026 that around 41,500 vehicles crossed the MLFF location on the first day. The system uses ANPR and FASTag-based electronic toll collection. Users with insufficient balance or an invalid tag receive an electronic notice (e-notice) and must pay the normal fee within 72 hours. After 72 hours the fee is twice the normal rate. Unpaid e-notices can lead to FASTag blacklisting and restrictions on other vehicle services through VAHAN.
For an operator, plate read rate and correct vehicle classification decide how much revenue the e-notice process must recover.
