This study examines carbon monoxide (CO) exposure and its associated health risks among commercial drivers and passengers. Carbon monoxide is a colourless, odourless, and highly toxic gas produced through the incomplete combustion of carbon-containing fuels such as gasoline, natural gas, and wood. Exposure to elevated concentrations of CO interferes with oxygen transport in the bloodstream by binding strongly to hemoglobin, thereby causing hypoxia and a range of adverse health effects, including headache, dizziness, nausea, confusion, breathing difficulties, and in severe cases, death. Commercial drivers are particularly vulnerable due to prolonged hours spent in traffic-congested environments and exposure to vehicle exhaust emissions, especially from poorly maintained vehicles. This study highlights the occupational and environmental risks associated with CO exposure among drivers and passengers, emphasizing the importance of awareness, preventive measures, and proper vehicle maintenance. It further discusses the role of employers and transport authorities in promoting safety through education, regular vehicle inspections, installation of carbon monoxide detectors, and enforcement of preventive policies. The study concludes that increasing knowledge and awareness of carbon monoxide poisoning among commercial drivers and the general public is essential for reducing exposure risks and improving public health outcomes.
