Objective. Blood alcohol concentration (BAC) was digitally determined for transport operators, passengers, and pedestrians in a southern Nigeria city.
Methods. The subjects were screened with a digital breathalyzer, Alco Scan CA 2000, for BAC along major accident-prone highways, resting spots, and hospitals. The mouthpieces were complemented with disposable straws for rapid and hygienic screening of the subjects.
Results. Based on convenience sampling, a significant proportion of Nigerians has a BAC level above 0.06 on accident-prone highways (44.60%), at resting spots (54.50%), and in hospitals (47.80%).
Conclusion. This research confirms that digital breathalyzer BAC levels are reliable and empirical means for determining incidents of alcohol-impaired driving.
