(WHDH) — Drowsy driving is reportedly a bigger problem on the roads than originally thought.
According to a study by the AAA Foundation for Traffic Safety, drowsy driving plays a role in eight times as many crashes as federal estimates suggest.
AAA found that in the crashes it analyzed, drowsiness was a factor in almost 10 percent of them.
They say it was a greater percentage in accidents that caused serious property damage.
The National Highway Traffic Safety Administration estimates that drowsiness was involved in just over one percent of crashes.
