Background: A driver’s vision is an important human factor necessary for safe driving.

Aim: The aim of this study was to determine the functional vision status of drivers in Nigeria and to establish its relationship with road traffic accidents (RTAs).

Setting: Designated road lay-bys and motor parks in Nigeria.

Methods: A cross-sectional study design was used for this study, with a sample size of 3521 vehicle drivers. Twenty-seven states and the Federal Capital Territory Abuja participated in the study. Participating drivers were interviewed, and clinical eye examinations were conducted by a team of optometrists at designated Federal Road Safety Commission road checkpoints and motor parks in the country.

Results: The mean age of the drivers was 46.3 ± 10.9 years. Of the 3500 participants, 3080 (88%) were men and 2780 (79.4%) had a driving licence. The percentage of drivers who underwent an eye test before being issued a licence was generally low (median, 43.5%). A history of RTA was reported by 8.3% of the drivers. The prevalence of visual impairment was observed amongst 7.5% of drivers (95% confidence interval [CI], 6.6% – 8.5%), whilst the prevalence amongst private drivers was 6.1% (95% CI, 4.6% – 7.9%). Drivers with visual impairment were nearly two times (adjusted odds ratio, 1.7; 95% CI, 1.06–2.77) more likely to be involved in RTA compared to those without impairment.

Conclusion: This survey has demonstrated the relationship between poor vision and the occurrence of RTA. All stakeholders must work together to ensure the safety of lives and property on our roads.
