Authorities say dozens of travelers have been injured—but no one killed—in a chain reaction of collisions on Interstate 75 along Florida's Gulf Coast. The Florida Highway Patrol said 52 people were hurt in 12 separate crashes involving 47 vehicles near the border of Sarasota and Manatee counties yesterday. Twenty-two people were taken to area hospitals, including two who were critically injured, though their injuries weren't life-threatening. Authorities attributed the collisions to heavy rain and driver error—essentially, people driving too fast for conditions. (More car accident stories.)
