(Reuters Health) - Drivers who hit the road on less than four hours of sleep are at least as likely to be involved in a crash as drivers who had too much to drink, a U.S. study suggests.
Brian Tefft, senior researcher at the AAA Foundation for Traffic Safety in Washington, D.C., reviewed data on more than 6,800 road accidents to study the effects of sleep deprivation on driving.
His findings showed that people who drove after getting less than seven hours of sleep were at higher risk for being culpable for the crash. That risk was greatest for drivers who slept less than four hours.
Recently, many road accidents here in Singapore were blamed on fatigue or sleepy driver. A police van driver crashed his van after falling asleep at the wheel. He was jailed for 3 weeks and disqualified for driving for three years.
Last year, a trailer crashed into three e-bikers and killed two of them in West Coast Highway. The driver who was at the end of his long working shift of more than 12 hours made no attempt to stop upon the collision.
According to report, heavy vehicles are claiming a disproportionate number of lives. They make up five per cent of the vehicle population but have been involved in three in 10 fatal road accidents in the last two years. Are heavy vehicles drivers more reckless? Or they are more fatigue as they spent longer hours at the wheel?
