Delhi’s border points witnessed strict vehicle checks on Thursday as enforcement agencies intensified action under Stage IV of the Graded Response Action Plan (GRAP) following a sharp deterioration in air quality. A thick blanket of smog covered key entry points, including the Delhi-Noida Direct (DND) Flyway, with the Air Quality Index (AQI) near the Chilla border slipping to around 490, placing it in the hazardous category.
Officials from the Delhi transport department and traffic police were seen stopping vehicles registered outside the capital, particularly those that did not meet BS VI emission standards. Non-compliant vehicles were either fined Rs 20,000 or asked to turn back from the border.
According to transport department officials supervising the checks, teams are verifying vehicle compliance using portable devices that allow instant confirmation of registration details, emission norms and Pollution Under Control Certificate (PUCC) validity. Drivers without valid PUCCs are also being penalised.
Old and non-BS VI vehicles under scanner
Barricades were placed along key routes to slow traffic and enable thorough inspection. Enforcement teams are specifically targeting vehicles that appear old or do not carry blue stickers indicating BS VI compliance. Traffic personnel from neighbouring states are also part of the joint operation at border points.
Officers said that diesel vehicles older than 10 years and petrol vehicles older than 15 years, especially those meeting BS-III or lower emission standards, are being stopped and fined as per existing rules. Authorities maintained that these measures are part of emergency steps to limit vehicular pollution during the winter peak.
Commuters voice frustration over enforcement
Some motorists expressed dissatisfaction with the sudden enforcement drive. A commuter from Faridabad, whose BS-III vehicle was stopped at the border, questioned the fairness of the checks, arguing that ordinary drivers were being penalised while larger systemic issues remained unaddressed. He also raised concerns about the lack of uniform checks on public transport vehicles.
Officials, however, said awareness about vehicular pollution norms has been repeatedly communicated and that enforcement teams have been deployed across all major entry points to prevent violators from using alternate routes to enter the city.
Vehicles a major contributor to winter pollution
Data shared by officials indicates that transport accounts for over 20% of PM2.5 pollution during winter months in Delhi-NCR. Of the nearly 2.88 crore vehicles in the region, about 93% are light motor vehicles and two-wheelers, while nearly 37% fall under BS-III or older categories. These older vehicles emit significantly higher levels of particulate matter and nitrogen dioxide compared to newer models.
Experts cited in media reports have pointed out that while vehicle restrictions may offer temporary relief, long-term solutions are necessary. Concerns have also been raised about the effectiveness of the existing PUC system, which does not adequately measure particulate emissions, and the need for stronger scrappage policies and improved public transport to address cross-border pollution.
Former transport officials have criticised what they described as last-minute enforcement measures, calling for consistent tailpipe emission checks, better inter-state coordination and the creation of a dedicated pollution control task force to tackle vehicular emissions more sustainably.
