Accidents involving transportation of petroleum products by road are of high frequency in Nigeria, mainly because of overdependence on the tanker-truck system due to pipeline vandalism. We analyzed over 92 accidents involving tankers-trucks from 2014 to 2019. In this study, the analysis is done to examine the factors that caused the accident using accident records and petroleum distribution data from the Federal Road Safety Commission (FRSC). Petroleum tanker-truck accident reports from the FRSC office in Abuja were used to examine the root causes of the petroleum truck accident. The operation time (OT), mean time between accident MTBA, accident rate, reliability, and unreliability (distribution) of the petroleum tanker-truck could be determined using Monte Carlo’s reliability analysis model. Thus, the data regarding the petroleum tanker-truck accident was collected from the safety and administrative department of FRSC for a six-year period and the PTD (Petroleum Tanker Drivers) arm of NUPENG (Nigeria Union of Petroleum and Natural Gas Workers) before they were further analyzed. Based on the explanatory results, the accident probability and relative accident consequence are identified. The elements that contributed to the accident were assessed for dependability and unreliability. The research showed that there is an increase in accident rate for the period of six years, and the reliability of some of the accident causal factors, such as human factor (HF), was at 4.286% in the first year and then decreased to 0.202% after the sixth year. This research work recommends safety personnels and regulatory bodies should properly monitor the accident rates of the petroleum tanker-trucks by adopting proper maintenance policies and proper sensitization of drivers. Since the majority of the accidents are cause by mostly humans, it surely improves the efficiency of the trucks and their working hours and will mitigate the rate of fuel tanker-truck accidents on Nigerian roads.
