Many accidents that are caused when a vehicle veers out of its lane and hits another car are believed to be the result of motorists being sleep deprived, driving under the influence alcohol or drugs, or suffering a serious medical condition. A new study confirms this.
According to a new study by the Insurance Institute for Highway Safety, incapacitation was the key factor in approximately 34% of lane-drift accidents studied as part of the research. Incapacitation here refers to a motorist dozing off while sleeping, blacking out in a medical emergency, or passing out under the influence of alcohol or drugs.
The research focused on approximately 630 lane-drift accidents that occurred between 2005 and 2007, and found that in approximately 17% of the accidents, the driver fell asleep at the wheel just before the accident. In another 17% of the crashes, the driver either blacked out at the wheel due to drug or alcohol use, or suffered a medical emergency like diabetic shock, seizure or heart attack.
