NHAI Opens Tamil Nadu's First Barrierless MLFF Toll at Paranur

The correct answer is Paranur Toll Plaza. It lies on the Tambaram-Tindivanam section of NH-179B and has become the first location in Tamil Nadu where the National Highways Authority of India charges toll without a boom barrier, letting vehicles roll through while cameras and FASTag settle the fee. Option A, Chorayasi, is wrong because that plaza is on the Surat-Bharuch section of NH-48 and lies in Gujarat, not Tamil Nadu. Option B, Gharaunda, is wrong because it sits on the Panipat-Jalandhar section of National Highway-44 in Haryana. Option D, Manoharpura, is wrong because it is one of the three plazas on the Delhi-Jaipur section of NH-48 in Rajasthan, the others being Shahjahanpur and Daulatpura. All three of these were converted to free-flow tolling earlier, but none of them is in Tamil Nadu, so only Paranur answers the question asked here.

The correct answer is Automatic Number Plate Recognition, usually shortened to ANPR. Cameras at the plaza read the registration plate of every vehicle that crosses, and the FASTag-based Electronic Toll Collection system then debits the user fee from the account linked to that vehicle. Option B is wrong because the free-flow system described for Paranur rests on plate reading and FASTag, not on satellite tracking of individual vehicles. Option C is wrong because no chassis number is broadcast anywhere in this arrangement; the chassis number is a manufacturing identity and plays no part in charging toll. Option D is wrong because the whole purpose of the change is the opposite: free-flow tolling is meant to cut human intervention in collection, so staff do not type registration numbers for passing traffic. Together, ANPR and FASTag allow charging without any halt.

The correct answer is the Tambaram-Tindivanam section of NH-179B. That is where Paranur Toll Plaza stands, and it is the stretch on which Tamil Nadu received its first barrier-less tolling arrangement from the National Highways Authority of India. Option A is wrong because the Surat-Bharuch section of NH-48 carries the Chorayasi plaza in Gujarat. Option C is wrong because the Panipat-Jalandhar section of National Highway-44 carries the Gharaunda plaza in Haryana. Option D is wrong because Urban Extension Road-II in the Delhi-NCR area carries the Mundka-Bakkarwala plaza. Each of those three is a genuine free-flow location, which is what makes them useful distractors, but the question asks specifically about Paranur, and that plaza belongs to the Tambaram-Tindivanam stretch of NH-179B in Tamil Nadu.
