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.
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.
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
