The National Highways Authority of India (NHAI) has clarified the payment structure for the Multi-Lane Free Flow (MLFF) toll system, which eliminates traditional toll booths for a more efficient, barrier-free experience on national highways. Under this system, tolls are automatically deducted via FASTag as vehicles pass through overhead gantries equipped with cameras and sensors. If a vehicle fails to complete a toll transaction, an electronic notice (e-Notice) will be issued, allowing the owner to pay the pending toll within 72 hours without incurring extra fees. Payments made after this period will incur a double toll charge. Motorists can verify and settle their dues through the official NIC portal, ensuring they maintain an active FASTag and sufficient balance to avoid penalties. NHAI emphasizes that user awareness and prompt action are essential for the MLFF system to function effectively, ultimately aiming to enhance travel efficiency and reduce congestion on highways.
