Even when not driving under the influence, everyone should know your limit, even on the straights. And practice predictive driving. Most of the time accidents are not occured by the driver, but drivers around them. And sometimes those drivers can be any one of us as well. Signal before turning, check your mirrors before over taking, look a few cars ahead on the road, etc. All these little steps can help prevent the loss of lives and our beloved vehicles.
And my deepest condolences to all involved in the accident. I just pray they all left us without pain or suffering.
