Pennsylvania bus driver Kelly Weber was over the legal driving limit four times with 54 students on the bus

A Pennsylvania school bus driver is accused of driving 54 elementary school students while drinking more than four times the legal alcohol limit, authorities said, after reports she swerved through traffic and nearly collided with vehicles before the bus ended up in a snowbank.

On Tuesday, Montgomery County Prosecutor Kevin R. Steele and Douglas Township Police Chief Robert B. Evans announced an arrest warrant for Kelly Weber, 46, of Boyertown.

Weber is charged with driving under the influence, 54 counts each of endangering the welfare of children, reckless endangerment and related offenses.

Police were alerted at about 4 p.m. on February 6 that a school bus was driving erratically and had missed other vehicles, authorities said.

An officer later found the bus parked on a snow bank.

Investigators said officers found an open 750ml bottle of Tito’s vodka, two empty 50ml bottles and a receipt showing the purchase of alcohol earlier that morning.

According to authorities, a blood test showed Weber’s blood alcohol concentration was 0.331%, more than four times the legal limit of 0.08%, and detected Delta-9 Carboxy THC.

Investigators said 54 children were on board the bus, including five under the age of 6.

Authorities said several children called or texted their parents during the trip because they were afraid to drive, and one child got out at an earlier stop and was picked up by his parents.

“More than 50 young children were in a dangerous situation created by this defendant, who chose to consume a large amount of alcohol and then get behind the wheel of a school bus and drive miles while intoxicated,” Steele said. “We are all grateful that this defendant did not crash into the bus and cause further harm to these children.”

Authorities said Weber checked into a rehabilitation facility after the accident.

She is expected to turn herself in for trial, at which time bail will be set.
