VIDEO: Why AZ freeways close after fatal wrecks

When someone's killed in a highway crash, DPS closes that stretch of road to investigate. It can take hours. Is it necessary?

With unfortunate accidents happening on a daily basis there is always a reason why freeways are closed off for hours at a time because of the tragic and unfortunate events that sometimes do take place. The video gives a little insight on to why exactly these closures last for so long, and why they should be respected as well. Sure many commuters will face crowding on the freeways, but in the big picture waiting in line to get through on your commute is nothing compared to what unfortunate situation took place to force the freeway to close down in the first place.
