Here's All About The New GRAP-4 Measures In Delhi Amid Worsening Air Quality

As Delhi-NCR faces "severe" air quality levels, authorities have enforced Stage 4 of the Graded Response Action Plan (GRAP) to combat air pollution. This strict measure aims to curb emissions from older vehicles and reduce pollution in the national capital region.

For the unversed, the Graded Response Action Plan (GRAP) is a set of emergency measures implemented in phases based on air pollution severity in Delhi-NCR. Stage 4, the most stringent phase, occurs when the air quality index (AQI) reaches "severe" levels, imposing restrictions on various vehicle types to control emissions.

The goal of GRAP Stage 4 is to reduce emissions and halt the deterioration of air quality immediately. Older vehicles with less stringent emission standards contribute significantly to air pollution, making these measures essential for public health and environmental safety.

Vehicles Restricted Under GRAP Stage 4

Commercial Vehicles

• Restricted: Diesel-run medium and heavy goods vehicles registered in Delhi with BS-IV compliance or below are banned.

• Exceptions: Vehicles carrying essential goods are permitted.

Interstate Trucks

• Restricted: Trucks carrying non-essential goods are prohibited unless powered by electric, LNG, or CNG powertrains.

• Diesel Trucks: Only BS-VI-compliant trucks can enter Delhi.

• Light Commercial Vehicles: Non-essential diesel vehicles must also be BS-VI compliant or use cleaner fuels to enter the city.

Private Cars

• Restricted: Movement of BS-III petrol cars and BS-IV diesel cars is not allowed in Delhi.

How To Check A Vehicle's BS Compliance Level

To determine whether your vehicle is compliant with GRAP Stage 4, you can use the following methods:

Registration Certificate (RC): Check the emission standard listed on your vehicle’s RC document.

Owner’s Manual: The manual includes detailed specifications, including the Bharat Stage (BS) compliance level.

Pollution Certificate: Refer to the Pollution Under Control (PUC) certificate, which also mentions the vehicle’s emission standard.

Manufacturing Year

Use your vehicle's manufacturing year to determine compliance:

• BS-I: Manufactured before 2000

• BS-II: 2001–2005

• BS-III: 2005–2010

• BS-IV: 2010–2020

• BS-VI: 2020 onwards
