Police said the delay in charging Ramona Jennings, 47, with drunken driving, reckless endangerment and risk of injury to a minor charges after the Nov. 26 incident was the result of M&J Bus Co., the private company that runs the school buses, waiting four hours to inform police of the situation, the Hartford (Conn.) Courant reported Thursday.
"We had to do everything in reverse," said police spokesman Sgt. Jeremiah Dunn.
The bus company said the delay was due to the time it took to get the bus driver to a health clinic to determine the cause of her impaired driving.
"We called the police as soon as we knew it was alcohol," said Michael Collins, vice president of M&J.
Police said a breath test at the clinic showed a blood alcohol content of 0.34 percent, several times the maximum 0.08 percent allowed by state law.
