Transport maintenance depots in Tanzania are critical for ensuring vehicles operate efficiently within a challenging operational environment characterized by frequent breakdowns and limited resources. A mixed-method approach was employed, including surveys, interviews, and data analysis. A regression discontinuity design (RDD) model was used to estimate treatment effects. There is a significant positive correlation (eta = 0. 53; 95% CI: 0. 32, 0. 74) between the number of technicians and maintenance efficiency scores, indicating that an increase in technician numbers leads to improved performance. The quasi-experimental design provided robust evidence for the effectiveness of transport maintenance depots in enhancing vehicle reliability and reducing operational costs. Investment should be prioritised in expanding technical capacity to further improve depot efficiency, particularly by increasing the number of trained technicians.
