Dive Insight:

It's yet another reminder of the dangers of road crew work: The two workers "were removing the final arrow board" when the accident occurred, Indiana Department of Transportation spokesman Nathan Riggs told the Indianapolis Star. That arrow board -- a directional sign board for traffic -- was struck by a passing pickup truck, whose driver also was injured.
