Truck drivers who have obstructive sleep apnea and who do not attempt to adhere to a mandated treatment program have a fivefold increase in the risk of a severe crash, according to a new study co-authored by Virginia Tech Transportation Institute researchers and featured in the March 21, 2016 online edition of the journal Sleep . Drivers who did not follow the sleep apnea treatment administered by the study fleet were discharged or quit, having been retained only one-third as long as drivers who did adhere to the treatment program.
