What role does alcohol and drug use play in tractor trailer wrecks?
Intoxicated Drivers. Over a period of one year, a study of truck driver fatalities was conducted by The National Transportation Safety Board and The National Institute on Drug Abuse in eight states. Comprehensive drug screenings were performed on blood specimens taken from 168 fatally injured drivers. One or more drugs was detected in 67% of these fatally injured drivers and 33% of these drivers had detectable blood concentrations of psychoactive drugs or alcohol.
