What is carbon monoxide, and how may it be harmful to drivers?

Carbon monoxide is a colorless, odorless gas that poses significant health risks, particularly in enclosed or poorly ventilated spaces. When inhaled, it binds with hemoglobin in the blood more effectively than oxygen does, leading to a decrease in the amount of oxygen transported throughout the body. This can result in symptoms ranging from headaches and dizziness to life-threatening conditions like carbon monoxide poisoning.

For drivers, exposure to carbon monoxide, which is often a byproduct of combustion engines, can impair their ability to operate a vehicle safely. This impairment can manifest through reduced alertness, vision problems, and even loss of consciousness, making driving extremely hazardous not only for the affected driver but also for other road users. Protecting oneself from this gas, especially in settings where vehicles are idling, is crucial for maintaining safety on the road.
