Effectiveness of road safety education in Nigeria using a quasi-experimental trial: Findings from the Road Safety Intervention Project

Road traffic injuries pose a serious public health problem worldwide, especially in low-income countries. The aim of this study was to determine the effectiveness of a post-license road safety education intervention programme in terms of increased knowledge and self-reported behaviour among commercial minibus drivers in Lagos, Nigeria. This was a quasi-experimental study conducted in three phases. Participating motor parks (selected by simple random sampling) were assigned to either the intervention or control group. All eligible minibus drivers were included with no matching. Data analysis was done with Epi-info version 3.5.1. Comparison was done in terms of group driver education versus no education, and pre- versus post-intervention. Out of an estimated 500 male drivers, 407 participated in the study. Most had some form of formal education. For both groups, pre-intervention knowledge scores were poor but improved significantly post-intervention in the intervention group. None of the drivers in the intervention group had good scores but this increased to 66,1% post-intervention. Their mean score increased from 34,4 ± 9,1 to 72,3 ± 10,2. Adherence to speed limits did not improve. The control group showed no significant changes. Post-license road safety education significantly improved knowledge but not self-reported adherence to speed limits. Similar, sustainable programmes should be offered to improve commercial drivers’ poor knowledge. Further studies are needed to determine deterrent factors to behaviour change.Keywords: road safety, intervention, commercial drivers, Nigeri
