A Florida bus driver taking kids to their graduation party was grilled by cops after a nightmare ride. Several dozen people were on the bus, which was taking graduating seniors to an amusement park, when they realized something was wrong. Someone called 911, alerting authorities. When cops got there, they gave the driver a sobriety test, which they say he failed. One mom says she took a photo of a booze can in the vehicle’s garbage. The driver was charged with DUI and child abuse.
