Micki Nolan, 3, and Glendora Holmes, 49, killed in wrong-way crash on US 521 in Georgetown County, South Carolina

  It looks like the most probable explanation for the crash is that Taran Nolan's car drifted into the wrong lane on the 521 Business Route about a mile south of Andrews, S.C.    The sign that designated two way traffic was very small, and among several other signs.   She had come off a divided highway and into the business route where the two lanes are in opposite directions.   Glendora Holmes could have come from a junction that would have required her to turn left onto the Andrews business route in the same direction as Taran.   But if she had missed the original exit to the South 521, back a half mile from the west, then she could have figured she could turn sharply right onto the southbound lane of the 521 business route.  That would have put both cars onto the same lane in opposite directions.   California would have had many cement barriers to prevent this.

It looks like the most, was Mrs. Nolan was on the phone and wasn't paying atention. Phones should be outlawed in any vehicle unless it is hands free. That is the bottom line, she was to busy talking with her husband. All of the other cars that day and many days before and after have not had a head on with one car in the wrong lane.

This accident was extremely tragic on so many levels. Sounds like signage could be better. But agree that Mrs. Nolan shouldn't have been on the phone.  ESPECIALLY if it was early morning/dark  she was from out of state and unfamiliar with the roads, and weather was foggy. At that point,  it is the responsibility of a safe driver to pull over until conditions are safe. NOT add further distractions by talking on the phone. As another poster stated, cars travel that road all the time. Likely in all sorts of condition. And they don't have head-on collisions. Prayers to both families for this accident.
