According to the authors, sleepiness has been shown to account for between 31 to 41 percent of major crashes of commercial vehicles. In 2001, large trucks were involved in 429,000 crashes. Nearly 5,000 of these crashes were fatal, which amounted to 12 percent of all U.S. traffic deaths. An additional 130,000 victims suffered nonfatal injuries. These accidents cost $76,637 per crash, but rose to $3.54 million after a fatal accident.
from the paper itself, OSA can be predicted reasonably well with a questionnaire and oximetry
Considering the risks I think mandatory screening of some sort is inevitable.
A recommendation has been made by a task force
Some progressive companies will probably start ahead of government requirements
A study sponsored by the FMCSA and the American Trucking Associations estimated that nearly one in three commercial truck drivers suffers from mild to severe OSA1. The study found that the risk of having sleep apnea depended on two major factors - age and degree of obesity - with prevalence increasing with both. Population projections by FMCSA indicate the number of older drivers will increase by 50% over the next twenty years. Other research demonstrates that drivers with undiagnosed OSA have an increased risk (2 to 7 times) for falling asleep at the wheel. It also increases the possibility of an individual developing significant health problems, such as hypertension, stroke, and ischemic heart disease.
