GRAP Stage 4 continues in Delhi as air quality remains in the ‘Severe+’ category, prompting authorities to enforce the most stringent level of the Graded Response Action Plan (GRAP). With the Air Quality
Index (AQI exceeding hazardous levels, several vehicle restrictions are in place to curb emissions and improve air quality. Under Stage 4, specific classes of older petrol and diesel vehicles are banned from operating in the National Capital Region (NCR) unless used for essential services. Vehicle owners must understand these restrictions and related challans to avoid penalties while commuting within Delhi-NCR.

What Is GRAP Stage 4?
GRAP Stage 4 is the highest level of response under the Graded Response Action Plan, activated when the region’s air quality deteriorates to Severe+ levels. This stage adds emergency measures to help control pollution sources, targeting vehicular emissions and reducing on-road contribution to poor air quality. The plan is enforced by the Commission for Air Quality Management (CAQM) and implemented across Delhi-NCR to protect public health.
Vehicle Restrictions You Must Know
Under GRAP Stage 4, BS-3 petrol and BS-4 diesel vehicles are banned from plying in Delhi-NCR, except when used for essential services. This ban includes private cars, two-wheelers, and commercial vehicles that do not meet the latest Bharat Stage emission standards. Vehicles that comply with BS-6 norms, as well as CNG and electric vehicles, are permitted to operate within the region without restrictions.
Commercial Vehicle And Truck Entry Rules
The restrictions extend to commercial transport. Diesel trucks and light commercial vehicles registered outside Delhi that do not meet BS-6 standards are barred from entering the city, unless they are carrying essential goods or serving emergency purposes. LNG, CNG, electric and BS-6 diesel commercial vehicles are allowed limited access under specified conditions.
Exemptions And Essential Services
Emergency vehicles, such as ambulances, police, and government service vehicles, are exempted from the vehicle ban even if they fall under older emission categories. Public transportation and goods services tied to essential sectors continue operating to ensure mobility for critical needs while pollution levels remain high.
Challans And Penalties For Non-Compliance
GRAP Stage 4 has been enforced strictly, and non-compliance can result in heavy penalties for both private vehicle owners and commercial operators.
- Using BS-III petrol or BS-IV diesel vehicles during this period can invite action under the Motor Vehicles Act.
- Fines can go up to Rs 20,000, and authorities are empowered to impound vehicles that violate the rules.
- Vehicles without a valid PUC certificate may face penalties of up to Rs 10,000, making timely renewal essential.
- The Delhi Police and Transport Department have stepped up on-ground enforcement and are using digital monitoring tools to identify violators and limit non-essential vehicle movement as pollution levels remain high.
- Vehicle owners are advised to stay updated, as additional or stricter measures may be announced if air quality worsens further.

What Else Is Restricted In Stage 4
Beyond vehicles, the Stage 4 restrictions typically halt non-essential construction, use of diesel generators (except emergency services), and certain industrial activities until air quality improves. There is also a switch to hybrid work models and online schooling to reduce outdoor exposure and lower pollution from traffic congestion. Understanding and complying with these restrictions can help residents avoid fines while contributing to efforts to improve air quality in Delhi-NCR.
