Similar to the way drinking and driving emerged as a road safety issue, impairment by fatigue, or drowsy driving is fast becoming a major concern worldwide. It can be just as deadly as drinking and driving, or unsafe speed.
According to the Transportation Safety Board of Canada (TSB), sleep and fatigue often leave no clues for investigators to trace. Unlike alcohol-related crashes, no blood, breath, or other test is currently available to determine levels of sleepiness at the time of a crash. This leaves investigators with little hard data on which to base a conclusion of fatigue or sleep as a cause or contributing factor.
Despite the data limitations, the TSB estimates about 5% of fatal crashes are firmly established as being caused by drowsy driving. Experts suggest the actual number may be as high as 20% to 40%. And that makes drowsy driving as dangerous as drinking and driving, which accounts for approximately 24% of all victims in vehicle fatalities.
Malignant transformation is a slow process. Children's ability to detoxify environmental chemicals is not fully developed. They lack certain mechanisms possessed by adults that enhance the removal of toxic chemicals from the body.
Thus children's exposures to environmental carcinogens must be minimised.
