Call for 30km/h Speed Limit in Red Zones Amid Rising Fatal Crashes in Delhi
New Delhi: The alarming rise in fatal crashes on Delhi’s roads has prompted renewed calls for stricter speed regulations. In 2025, the city recorded 1,578 fatal crashes, a slight increase from 1,504 in 2024. This situation has raised concerns about the effectiveness of the current speed limits, which vary widely across the city, with some roads allowing speeds of 50 km/h and others permitting 60 km/h or even higher on highways that traverse densely populated areas.
Current Speed Limit Situation
Delhi’s roads operate under a confusing patchwork of speed limits. This inconsistency has been a focal point of discussions among experts, policymakers, and civil society groups. A recent seminar organized by the Road Safety Network (RSN) in collaboration with IIT Delhi and IIT Kharagpur highlighted the urgent need for a uniform speed limit of 50 km/h on urban roads, with even stricter limits proposed for residential areas, school zones, and pedestrian-heavy corridors.
The Impact of Speed on Road Safety
Bhargab Maitra, a professor of civil engineering at IIT Kharagpur and a member of RSN, emphasized the significant role of highways in fatal crashes. He pointed out that while national highways constitute only 2% of India’s road network, they account for over 36% of road fatalities. Speeding has been identified as the primary risk factor, particularly for vulnerable road users such as pedestrians and cyclists.
Highway Safety Concerns
During the seminar, experts discussed how high speeds are incompatible with Indian road conditions, which often feature mixed traffic, frequent access points, and inadequate protection for pedestrians and two-wheelers. Treating highways as uninterrupted high-speed corridors poses severe risks, especially when they pass through urban areas.
Global Perspectives on Speed Limits
David Cliff, CEO of the Global Road Safety Partnership in Geneva, noted that even modest speed reductions could lead to significant decreases in fatalities and serious injuries. He recommended a speed limit framework that includes:
- 30 km/h in urban areas
- Under 80 km/h on rural roads
- 100 km/h on expressways
Urban Road Fatalities
Contrary to popular belief, most fatal crashes in urban areas do not occur in narrow lanes but rather on wide arterial roads, flyovers, and signal-free corridors, often during low-traffic hours when drivers are tempted to speed. Data indicates that speeding was responsible for 68.1% of all road fatalities in India in 2023, with 72.5% of these deaths occurring on national highways. Even a 1 km/h increase in average speed can raise the risk of injury crashes by 3% and fatal crashes by up to 5%.
Commute Times vs. Safety
Participants in the seminar rejected the notion that lower speed limits would significantly worsen commute times. They argued that in already congested cities, speed caps have minimal impact on travel durations but can dramatically reduce fatalities. Additionally, lower speeds can improve air quality and enhance public health and neighborhood livability.
Challenges in Traffic Enforcement
Experts acknowledged that traffic enforcement faces several structural challenges, including manpower shortages, unpaid fines, and diminishing deterrence. While speed cameras and technology can aid enforcement, they cannot compensate for unsafe road designs. Instead, roads should be designed to be “self-explaining,” utilizing lane narrowing, traffic calming measures, and safer junction designs to naturally slow down drivers.
Proposed Speed Framework
A three-tier urban speed framework received broad support during the discussions:
- 30 km/h for neighborhoods and school zones
- 40 km/h for mixed-use corridors
- 50 km/h for limited-access arterials with pedestrian segregation
Experts warned that frequent changes in speed limits can lead to confusion and non-compliance among drivers.
Recommendations for Speed Management
Participants advocated for area-specific speed limits, the reclassification of urban highway stretches that pass through dense settlements, and the establishment of institutional responsibility for setting and reviewing these limits. They emphasized that speed management should be integrated with public health, air quality, and noise policies, supported by better crash data, capacity-building, and public engagement.
Conclusion
Professor Geetam Tiwari of IIT Delhi’s TRIPP Centre highlighted the gap that often exists between road design, speed limit implementation, and public compliance. He stated, “Global evidence is clear that 50 km/h is the absolute maximum safe speed in urban areas.” As Delhi grapples with rising fatal crashes, the call for a uniform speed limit of 30 km/h in red zones is more pressing than ever.
