The Ministry of Road Transport and Highways amended the Central Motor Vehicles Rules, 1989 to permit up to 100 per cent ethanol (E100) in flex-fuel vehicles.

It also introduced an annual concessional toll pass for eligible non-commercial vehicle owners living within 20 km of a National Highway fee plaza.

Both steps support the ethanol-blending push and ease local commuters' toll burden.

How the exam will ask it

ప్రిలిమ్స్

  • E100 refers to fuel containing up to 100 per cent ethanol; a flex-fuel vehicle can run on petrol, ethanol or a blend of both.
  • The Central Motor Vehicles Rules, 1989 are framed under the Motor Vehicles Act, 1988 and are administered by the Ministry of Road Transport and Highways.
  • The concessional annual toll pass is meant for non-commercial vehicle owners residing within 20 km of a National Highway fee plaza.
  • Ethanol blended with petrol reduces crude oil import dependence and is produced mainly from sugarcane-based feedstocks in India.

మెయిన్స్

GS3 (Energy, Infrastructure). Allowing E100 in flex-fuel vehicles through a CMVR amendment gives legal backing to the ethanol-blending push, cutting oil import dependence and supporting farm incomes, while the concessional toll pass eases the burden on residents near fee plazas. The way forward lies in assured ethanol supply without straining food crops and water, expanding fuel pumps and flex-fuel vehicle availability, and designing the toll concession so that it does not erode highway revenue.

Quick recall

Answer before you reveal

The Supreme Court struck down a Karnataka law validating a recruitment whose cancellation courts had upheld, holding that the legislature cannot nullify judgments. This reflects the constitutional principle of:

  1. Doctrine of Eclipse
  2. Doctrine of Pith and Substance
  3. Separation of powers
  4. Doctrine of Severability
సమాధానం చూడండి

సమాధానం: C — Correct: Separation of powers — A legislature may change the law on which a judgment rests, but cannot directly annul a court's judgment; that would breach separation of powers. • Doctrine of Eclipse — wrong: The Doctrine of Eclipse concerns pre-Constitution laws inconsistent with fundamental rights, not validating laws. • Doctrine of Pith and Substance — wrong: Pith and substance resolves overlaps between Union and State List subjects, not legislative overriding of judgments. • Doctrine of Severability — wrong: Severability allows the invalid part of a law to be cut off from the valid part; it does not address nullifying judgments.
