Abstract

Truck-related accidents have become a pressing public safety and economic issue across Tanzania, especially along major transport corridors like the Dar es Salaam–Tunduma Road. This highway, a crucial part of the Central and Southern African Development Community (SADC) transport network, experiences a disproportionately high number of heavy vehicle crashes. This study aims to assess the major factors contributing to truck accidents along the Dar es Salaam–Tunduma Road and to provide evidence-based recommendations for mitigation. Using a structured questionnaire distributed through Google Forms, this research collected data from drivers, transport officers, logistics professionals, and other road users with firsthand knowledge of the corridor. The study employed a mixed-methods approach. Quantitative responses were analyzed using descriptive statistics, while open-ended responses were categorized thematically to capture insights into perceptions and lived experiences. The findings reveal that driver-related factors, such as fatigue, long working hours, and limited rest periods, play a significant role in accident causation. More than 70% of respondents identified these factors as “highly influential.” Road infrastructure was another major concern, with 64% of participants pointing to potholes, poor road design, lack of signage, and absence of designated lanes for heavy trucks. Additionally, 53% cited mechanical issues—especially brake and tire failures—as common causes of accidents. The study also revealed perceived weaknesses in the enforcement of traffic regulations, including insufficient inspection protocols, corruption among enforcement officers, and a lack of consistent penalties for violations. Respondents proposed practical interventions such as the establishment of truck-only lanes, installation of fatigue-monitoring systems, stricter licensing procedures, and improved inspection routines. Several participants also suggested regular refresher courses for truck drivers and investment in smart transport technologies to monitor vehicle health and driver behavior in real time. The paper concludes by proposing a set of policy and operational recommendations tailored to the Tanzanian context. These include establishing rest areas at strategic intervals, implementing mandatory driver fatigue management policies, investing in road redesign in high-risk zones, and strengthening institutional oversight of road transport regulation.
