At which toll plaza has Tamil Nadu's first Multi-Lane Free Flow (MLFF) tolling system been started?

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.

The correct answer is that the exempted FASTag must still be renewed every year, because this is precisely the requirement the revision removes. Earlier guidelines made annual renewal compulsory; the new framework sets validity by the recorded percentage of disability so that beneficiaries are spared repeated formalities. Option A is correct and therefore not the answer, since the slabs of five years and three years follow directly from the recorded percentage. Option B is correct as well: a valid Disability Certificate, a Unique Disability Identity Card or other applicable records are accepted to establish that percentage. Option D is also correct, because the exemption extends both to vehicles specially designed and built for use by persons with physical disabilities and to vehicles registered under the ownership type recorded as Divyangjan.

The correct answer is 2 October 2026. The ministry announced the revision and stated that the new guidelines would come into force from that date, covering both the issuance and the renewal of exempted FASTags for eligible Divyangjan and persons with disabilities. Option A is wrong because that is the day the announcement itself was made public, not the day the framework begins to operate, and exams frequently set the announcement date against the effective date to see whether a candidate reads carefully. Option C and option D are wrong because no such deferment was provided; the ministry did not push the start into November or into the next financial year. Along with the date, remember that the change replaces compulsory annual renewal with validity fixed by the recorded percentage of disability.

The correct answer is five years. The revised framework of the Ministry of Road Transport and Highways ties the validity of an exempted FASTag to the percentage of disability on record, and the higher slab of 70 to 100 per cent carries a validity of five years. Option A is wrong because yearly renewal was the earlier practice that this revision does away with; it is no longer the rule for any slab. Option B is wrong because three years is the validity for the lower slab, that is a recorded disability of 40 to less than 70 per cent, so the figure is real but attached to the wrong group. Option D is wrong because no slab under these guidelines runs for ten years. After the validity ends the tag may be renewed, provided the holder is still eligible and the conditions of the National Highways Fee Rules, 2008 are satisfied.
