Digital enforcement strategies such as electronic challan (E‑Challan) systems are increasingly adopted to improve compliance with road safety regulations. However, their impact on public health outcomes, including injury incidence and mortality, remains largely unquantified. Framing digital enforcement within the World Health Organization’s Safe System Approach emphasizes systemic responsibility integrating technology with policy, infrastructure, and outcome monitoring. This letter advocates for interoperable data systems linking enforcement and health outcome data, regular reporting of key indicators, and evidence‑based evaluation to ensure that digital enforcement contributes meaningfully to preventable RTIs and supports broader road safety governance.

The recent implementation of an automated E-Challan system represents a shift toward technology-driven enforcement; however, its public health impact remains unquantified. This commentary advocates for integrating digital enforcement into a Safe System Approach, framing it as a tool for injury prevention rather than mere revenue collection. We highlight the critical need for data transparency and a structured evaluation framework to monitor RTI mortality and compliance trends. Establishing evidence-based oversight is essential to ensure that Karachi’s digital governance effectively reduces preventable road mortality. To The Editor, Road traffic injuries (RTIs) remain a significant public health challenge in Pakistan, contributing substantially to mortality, long-term disability, and economic burden [1,2]. National surveillance indicates that young working men are disproportionately affected due to higher road exposure and risky driving behaviors [2]. In Karachi, dense populations and mixed traffic patterns amplify this risk, resulting in increased healthcare demand and decreased workforce productivity. To address limitations of manual traffic monitoring, Karachi recently introduced an electronic challan (E-Challan) system, an automated camera-based enforcement mechanism. This system employs Automatic Number Plate Recognition to detect violations, including helmet non-compliance, seatbelt infractions, and overspeeding, leveraging deterrence principles to encourage safer driving behavior [3,4]. However, the system’s impact on public health outcomes remains unassessed. Enforcement alone is insufficient. Integrating E-Challan within a Safe System Approach, which combines technology, policy, and infrastructure to prevent fatal errors, is essential. Effective implementation also requires data transparency, continuous monitoring, and standardized enforcement supported by independent oversight [5]. Systematic reporting of RTI data would allow identification of high-risk locations, analysis of behavioral trends, and tracking of outcomes over time. We recommend establishing a structured evaluation framework incorporating key indicators such as RTI incidence, injury severity, and mortality trends [6]. Transparent sharing of enforcement and outcome data with public health researchers would enable evidence-based policy adjustments and strengthen Karachi’s urban road safety strategy. Positioning E-Challan as a public health intervention rather than merely a punitive tool underscores the city’s systemic responsibility, aligns with global road safety frameworks, and maximizes the technology’s life-saving potential. Karachi’s experience offers actionable lessons for other LMIC urban centers considering digital enforcement as part of comprehensive road safety programs. References 1. World Health Organization.
