Death Rate Due To Speeding Drops Sharply In U.S. - Down To One-Third of Rate From 1980s

The rate of deaths caused by speeding in America per mile driven has declined to one-third of the rate from the 1980s when NHTSA first began to track auto-related deaths caused by speeding. In 1986, the peak for speed-related deaths recorded in America, the rate was 9.2 deaths per billion vehicle miles traveled. That rate had dropped to just 3.2 deaths per billion vehicle miles by the year 2016.

And it isn't just the rate of deaths that has fallen. The total number of Americans killed in speed-related incidents has dropped from a high in 1986 of 16,937 to a low of 9,283 in 2014. Speed-related deaths have dropped to under 10,000 per year in the past four of five years (with 2017 being the latest year for which data is available). This despite Americans doubling their driven miles from the '80s to the present day.

Another fact makes the drop in speeding-related deaths even more significant. Many states raised their top speed limits from 55 MPH to as high as 80 MPH during the past few decades. Yet, despite the higher speed limits, speeding deaths overall continue to drop. On reason for this is that more than half of speed-related deaths occur on roadways that have a speed limit below 55 MPH. Speed itself is not the problem. Excessive speed for a given situation is.
