Fog-Shrouded Highway Pileup in Bulgaria Kills 12, Injures Dozens

At least 12 people were killed and dozens injured in a series of crashes caused by thick fog on a highway in Bulgaria, the country's prime minister said.

Police, firefighters and paramedics were sent to the scene for the rescue.

Breaking Now's reminder as winter driving season begins: when fog rolls in, slow down, turn on low-beam headlights and leave plenty of room. Most chain-reaction crashes start with one driver going too fast to stop.
