Traffic Deaths Down So Far In 2018

There is good news on the highways lately, namely that preliminary data for the first half of 2018 show a 3.1% decrease in traffic deaths, and 2017 saw a 1.8% decrease as well following two straight years of significant increases.  This is true despite the fact that the economy is still improving and there is thus more driving going on now than a few years ago.

So what happened in 2017-2018?  Well, gas prices began rising again, after plummenting in 2014-2015 and reaching a low in the spring of 2016.  And we know that there is an inverse correlation between gas prices and traffic fatalities.  gas prices still remain well below their 2011-2014 average levels, even as some states raised their gas taxes.  So that only explains part of the picture.  And alcohol taxes, already historically low, have actually dropped since the Republican tax bill.  So what else could it be?

The general secular trend in traffic deaths per vehicle miles traveled has been downward for decades, so this recent decrease could simply be reversion to the mean following the 2015-2016 spike in fatalities, at least in part.  But the fact that so many states recently legalized cannabis from 2016-2018, and the proverbial dust has settled in the few states that had done so earlier, at the very least casts serious doubt that the previous spike in fatalities was caused by legalization, and supports the idea that legalization may have even reduced such deaths by displacing alcohol use and thus drunk driving as well.

Thus, as we have noted time and again, cannabis legalization was not a disaster after all, and seems to have been a net benefit to public health and safety overall.  Next step is to legalize it at the federal level and in all 50 states and all territories as well, and also to lower the age limit to 18 like Canada now has.

So what are we waiting for?
