NHAI standardises highway designs for tolling without stopping vehicles

The National Highways Authority of India announced guidelines on 6 November 2026 to standardise infrastructure for Multi-Lane Free Flow tolling on national highways with four or more lanes. The framework was announced in New Delhi and featured in news on 7 November 2026. It covers future projects as well as projects under construction. The proposed collection system allows vehicles to move through a tolling zone without stopping at a physical barrier.

The guidelines address plaza layouts, the arrangement of lanes, overhead gantries, lighting, signs and supporting facilities. Projects at the detailed project report stage must incorporate the new design. For projects already awarded or under construction, changes will follow the relevant contract provisions. Advance information and electronic message signs are intended to guide users safely through the collection zone. The framework also provides for an administrative building and facilities to operate and maintain the plaza.

Facts to remember

• Announcement: 6 November 2026; coverage includes national highways with four or more lanes.
• MLFF stands for Multi-Lane Free Flow; vehicles need not stop at physical barriers.
• The design framework applies to future projects and those under construction.
• NHAI was constituted under the National Highways Authority of India Act, 1988.

Background

NHAI develops, maintains and manages national highways entrusted to it by the Central Government. Its statutory origin lies in the 1988 Act. Highway planning includes the infrastructure required to operate and maintain a road as well as the carriageway itself. Tolling infrastructure is part of that operational framework. A design standard sets requirements for infrastructure; its announcement should be distinguished from completion of works at individual locations.

Why it matters for exams

For CLAT Economy and general knowledge, revise transport infrastructure and statutory authorities, and distinguish a design guideline from a completed rollout.
