Car Wreck Deaths Up 13% in 2012

As reported by CNN, the first quarter of 2012 saw what could be characterized as an unusual increase in the number of fatal car wrecks on the nation's roadways. Among the cited factors is distracted driving, which has gained prominence, so to speak, as mobile technology has improved in recent years. Other possible factors playing a role in the 13.5% increase include the warmer winter (meaning that more people were out on the roads) and driving under the influence of alcohol or drugs.

In short, what the Automobile Association of America would like to see is a stronger "culture of safety" among drivers, who decide not to text while driving, get behind the wheel after drinking, or engage in other risky behavior like speeding. What makes this increase particularly troubling is we were at a 60-year low in traffic deaths across the nation, based on data compiled by the National Highway Traffic Safety Administration, until the first quarter of 2012. In other words, more than 7,600 people lost their lives in motor vehicle accidents in the first quarter of 2012, or roughly 1,000 more than in first-quarter 2011, reversing what Barnett characterizes as a "downward trend" that had stretched back for years.
