The authors of research looked at fatal car crash data from a U.S. national database of more than 570,000 collisions between 1994 and 2011 and found there appears to be no safe level of alcohol in the bloodstream when it comes to driving, Fox News reports.

The data they analyzed included blood alcohol content (BAC) measurements for the drivers as well as clear indicators of blame for the accident, such as which driver ran a red light or drove in the wrong lane.

Drivers with a BAC of .01 percent, the lowest level recorded in the dataset, were 46 percent more likely to be solely blamed for the crash than a sober driver, according to the results published in the journal Injury Prevention.

For men and women, as blood alcohol level increased, so did the possibility of blame for the accident.

Although the study builds on 50 years of similar research, this one is unique and exciting because of its scale, said James C. Fell, senior research scientist at the Pacific Institute for Research and Evaluation in Calverton, Maryland.
