BS4 Truck Ban in Delhi from 1 Nov 2026: Who Can Enter

A BS-IV truck that rolled into Delhi without trouble all of last year will be stopped at the border from 1 November 2026. The one-year grace period that let older diesel goods vehicles keep entering the capital ends on 31 October, and a separate winter ban announced by the Delhi government sits on top of it.

This guide explains both rules as they stand on 29 October 2026: which trucks can still enter, which are exempt, how to check your own vehicle, and the practical options for operators whose fleet is still BS-IV.

BS4 truck ban in Delhi: what changes on 1 November 2026

From 1 November 2026, a goods vehicle registered outside Delhi can enter the city only if it is BS-VI diesel, CNG, LNG or electric. BS-IV and older diesel trucks registered in other states will be turned back.

• Who is affected: light, medium and heavy goods vehicles (LGV, MGV and HGV) registered outside Delhi.
• What is allowed: BS-VI diesel, CNG, LNG and electric goods vehicles.
• What ends on 31 October 2026: the transitional entry allowed for BS-IV goods vehicles, and the limited exemption for BS-IV vehicles carrying essential goods.
• Who is not covered: goods vehicles registered in Delhi.

On top of that, the Delhi government has announced a winter restriction on all non-BS-VI vehicles registered outside Delhi from 1 November 2026 to 31 January 2027, with CNG, electric and essential-service vehicles exempt. Both are explained below.

Where the rule comes from

The goods vehicle rule is a statutory direction of the Commission for Air Quality Management (CAQM), the body that runs air pollution control across Delhi and the National Capital Region.

Under CAQM Direction No. 88, commercial goods vehicles registered outside Delhi lost the right to enter the city from 1 November 2025 unless they were BS-VI, CNG, LNG or electric. An amendment of 17 October 2025, reported at the time by The Tribune, gave BS-IV goods vehicles a one-year transition up to 31 October 2026. BS-III and older diesel goods vehicles from outside Delhi were barred outright from 1 November 2025.

The same direction allowed vehicles carrying essential commodities a limited exemption, also only until 31 October 2026. After that date, essential supplies coming in from outside Delhi also have to move in BS-VI, CNG, LNG or electric vehicles.

On 16 and 17 October 2026, Gurugram Traffic Police issued an advisory restating that BS-IV and older goods vehicles will be stopped from entering Delhi from 1 November. No extension had been announced as of 29 October 2026.

The winter ban on non-BS-VI vehicles, 1 November 2026 to 31 January 2027

Separately, Delhi Chief Minister Rekha Gupta announced on 20 October 2026 that vehicles registered outside Delhi and below BS-VI will not be allowed into the city from 1 November 2026 to 31 January 2027, as part of the winter pollution plan, as reported by Autocar India and other outlets.

• Scope: reports describe it as covering all non-BS-VI vehicles registered outside Delhi, not only goods vehicles. Most coverage includes private cars; some reports describe only commercial vehicles. The official order text had not been published when this guide was written.
• Exempt: CNG and electric vehicles, and essential and emergency services such as ambulances and fire services.
• Also announced: fuel stations will refuse petrol, diesel, CNG and LPG to vehicles without a valid PUC certificate, and parking charges at municipal lots are doubled.

For a truck operator the practical effect is the same: a BS-IV goods vehicle from outside Delhi cannot enter from 1 November under either rule, and the CAQM rule continues after the winter ban ends on 31 January 2027.

Which trucks can enter Delhi from 1 November

• BS-VI diesel goods vehicles, from any state. These form the bulk of trucks sold since April 2020. Trucks India lists every current BS-VI truck with price and payload.
• CNG trucks, which are exempt from both rules. See the CNG truck listings and what they cost to run in the CNG running cost guide.
• LNG trucks, allowed under the CAQM direction. Trucks India lists the LNG trucks on sale.
• Electric goods vehicles, exempt from both rules. See the electric truck listings.
• Goods vehicles registered in Delhi, which the CAQM rule does not cover, whatever their emission class.

Restrictions under each stage of the Graded Response Action Plan (GRAP) still apply on top of this. When a higher GRAP stage is in force, entry of trucks into Delhi can be restricted further, so check the stage in force on the day of dispatch.

How to check whether your truck is BS-IV or BS-VI

1. Look at the RC. The registration certificate carries the emission norm, written as "Bharat Stage IV" or "BS-VI" in the norms field. The RC details guide explains how to pull it up on Vahan or mParivahan if you do not have the paper RC to hand.
2. Check the registration date. BS-IV vehicles could not be sold or registered in India from 1 April 2020, so almost every truck first registered after that date is BS-VI, and a diesel truck registered before it is BS-IV or older.
3. Check the fuel. A truck registered as CNG or electric is exempt, whatever its age, as long as the RC records that fuel.

There is no approved way to upgrade a BS-IV diesel truck to BS-VI. The BS6 emission norms guide explains what changed between the two stages and why the hardware differs.

What BS-IV truck owners can do

Stop at the border and transship. For regular Delhi deliveries, unload at a yard outside the border and move the goods in on a BS-VI, CNG or electric vehicle. Inside the city, goods vehicles of every class also face daytime and peak-hour entry windows, which the heavy vehicle no entry timings guide sets out.

Route through traffic around Delhi. Trucks that only pass through can use the Eastern and Western Peripheral Expressways instead of entering the city.

Put BS-VI or CNG trucks on Delhi routes. Operators with mixed fleets can keep BS-IV trucks on routes that do not touch Delhi and move compliant vehicles onto Delhi work.

Replace the vehicle. For an owner whose work is mostly in Delhi, the ban changes the replacement sums. A scrappage certificate earns a discount on a new vehicle and a road tax concession in many states, which the vehicle scrappage policy guide explains. An electric truck or a CNG truck also clears the winter ban.

Keep the PUC valid. Even a compliant truck without a valid pollution certificate will be refused fuel at Delhi pumps under the winter plan. The PUC guide covers validity and renewal.

Will the BS-IV deadline be extended?

Transport associations asked for more time when the rule was first made in October 2025, and some said they would go to court if BS-IV trucks were barred after the one-year transition. As of 29 October 2026, no extension had been announced, the Gurugram Traffic Police advisory restated the 1 November date, and the Delhi government added its winter ban on top. Plan on the rule taking effect, and check the CAQM and Delhi Transport Department notices before dispatching a BS-IV truck towards Delhi.
