Police say charges still pending in school bus crash near Liberty High; driver’s blood test results expected in a few weeks

Maryland State Police said Wednesday that results from blood tests performed on a driver who crashed a school bus near Liberty High School Sept. 15 would take between 30 and 60 days to be returned to Westminster from a state lab.

Once blood test results are received, police will confer with the Maryland State’s Attorney’s Office to determine if charges should be filed against Tammy J. Frock, 54, of Westminster, a driver for Johnson Bus Service, LLC, of Westminster, which contracts with CCPS.


Frock was arrested Sept. 15 at the scene of the bus crash after state troopers said they observed signs of intoxication. She was released from custody that day, according to police.

A representative with Johnson Bus Service said Wednesday that Frock’s arrest is still under investigation. Carey Gaddis, communications officer for CCPS, stated in an email Wednesday that Frock is not driving for the school system and a spare bus is being used for the route.


Police said Frock was driving a 2016 school bus at about 2 p.m., Sept. 15 when she went off the right side of the road and hit power poles on Route 32 north of Bartholow Road in Eldersburg. Damage to the poles and lines was severe and police shut down the road that afternoon. Crews from Baltimore Gas and Electric and the Maryland State Highway Administration also responded to the scene and the road was reopened at 11 p.m., after BGE repaired the electric lines.

No students were on the bus at the time of the crash, according to state police.

CCPS bus drivers are employees of independent bus contractors and are certified to drive a school bus by the school system based on Maryland Department of Transportation regulations. All CCPS-certified drivers must complete background checks, including a preemployment physical with drug and alcohol screening. Drivers must submit to random drug and alcohol testing by Carroll Occupational Health, according to Gaddis.
