The rule closes the transition period that was given to BS-IV vehicles last year. Transporters who run trucks and buses into Delhi from other states will need to check their fleet now, and those planning a purchase can compare the full list of new trucks on TrucksBuses to see what is available.
Which Vehicles Are Covered
According to the advisory, the ban applies to commercial goods vehicles that conform to BS-IV or lower emission standards. This includes light goods vehicles (LGVs), medium goods vehicles (MGVs), heavy goods vehicles (HGVs) and other trucks. The advisory also covers buses that meet BS-IV or older standards.
Which Vehicles Can Still Enter Delhi
Three categories remain exempt under the announced rules: CNG vehicles, electric vehicles, and diesel trucks and buses that meet BS-VI standards. For operators looking at the electric route in the goods segment, TrucksBuses lists the Eicher Pro X EV 3.5T, which has a GVW of 3,490 kg and a 107 HP motor, with 32 kWh and 40 kWh battery options.
Buses: Delhi-Registered Exempt, Tourist Permits Covered
The advisory says the restriction does not apply to buses registered in Delhi. Buses that operate under All India Tourist Permits (AITPs) and other service arrangements will face the restriction if they meet BS-IV or older norms, which makes this especially relevant for outstation tourist and contract operators who run into the capital.

Background: CAQM Direction and the BS-IV Transition
The rule follows a direction from the Commission for Air Quality Management (CAQM). Under it, commercial goods vehicles registered outside Delhi and not compliant with BS-VI were barred from the city from 1 November 2025, while BS-III and older vehicles were stopped at that time. BS-IV commercial goods vehicles were allowed in for a limited period as a transitional measure, up to 31 October 2026. Commercial goods vehicles registered in Delhi, and those running on CNG, LNG or electricity, were not restricted. Curbs under the Graded Response Action Plan (GRAP) can also continue to apply for commercial vehicles whenever a stage is enforced.
What Operators Should Check Before 1 November
Gurugram Traffic Police have appealed to transporters, drivers and bus operators to verify their vehicles' emission standard and registration details and to confirm eligibility before entering Delhi. Operators can start by checking the BS norm printed in the registration certificate and by confirming whether the vehicle runs on CNG or electricity. If you are thinking of buying an older vehicle, look at the emission standard first, since not all listings among used trucks and buses will meet the BS-VI requirement.
Replacement Options for Fleet Owners
Owners of BS-IV trucks and buses who still need to run into Delhi have three broad options: switch to a BS-VI diesel vehicle, move to CNG, or choose an electric vehicle. The right choice depends on route length, load and local fuelling or charging access. The authorities have not announced any further extension of the transition period, so operators should plan on the 1 November date.
What This Means for Bus Operators
For bus operators, the key point is registration: Delhi-registered buses are exempt, while buses registered elsewhere need to meet BS-VI or run on CNG or electricity. CNG is one route for staff and tourist operators, and TrucksBuses lists buses such as the Tata Starbus Prime LP 913/52 CNG, a 51-seater. Operators should confirm the latest rules with the Delhi transport department or traffic police before sending a vehicle into the city, since enforcement details can change.
