Roadway fatalities dropped slightly year over year, but are still up significantly over the last five years.

According to the National Safety Counsel, about 40,000 fatalities occurred in 2018. That’s down about 1% from 2017 but 14% higher than the fatality figure in 2014. The report estimates that more than 4 million people were seriously injured in roadway collisions in 2018. That’s also a 1% decrease from 2017.

The report also found that driver behavior is a key factor in the number of fatalities remaining high. About 8% of fatal crashes were the result of distracted driving, while 2% involved drowsy driving. Motor vehicle crashes are the second most common accidental cause of death in the United States. Accidental opioid overdoses surpassed them for the first time last year.
