What's behind the spike in fatal traffic accidents?

Traffic Deaths Rise 2015

The U.S. is on a pace for what could be the deadliest year on the roads since 2007. According to the National Safety Council, between January and June, about 18,630 people died in traffic accidents across the country -- that's up 14 percent from the same period in 2014 -- and more than 2.2 million were seriously injured.

"We see spikes in distracted driving, in speeding, and in impaired driving. Lots of weekend parties, long holidays, a lot of alcohol is consumed and so unfortunately we see an uptick in those impaired driving crashes," NTSB said.

Drinking, speeding and using your phone while driving is a "triple threat of danger" on highways, but there's more to danger than just texting and driving.

"It's all distractions. People have got to stay focused on the road," NTSB said. "It just takes a split second, but that's why we see those fatality and injury numbers going up."
