Is your Truck Putting You to Sleep?

A ground-breaking bit of research from Australia has shown that low-frequency vibrations can make drivers drowsy. If this is true and the research is proven conclusive, it will call into question just about all we assume about truck crashes where the driver apparently fell asleep at the wheel. Those drivers may in fact have been very drowsy but may not have been "fatigued" in an hours-of-service (HOS) context, the way that term is typically applied to "tired drivers."
