ZACHARY - Police arrested a school bus driver in Zachary after they said she was driving erratically Friday morning and admitted to taking drugs.

Zachary Police arrested 52-year-old Darlene Crain on charges of driving while intoxicated and improper lane usage. The school system said Crain is employed by First Student, who handles busing duties for Zachary.

Police said they received a call around 7 a.m. of Crain's bus weaving around while it was between Highway 64 and Highway 964. Officers stopped the bus in the parking lot of Zachary High School and said Cain's speech was slurred and she performed poorly on a field sobriety test, swaying from side to side. Officers said after she was arrested Crain admitted she had taken Percocet, Xanax and Ativan before getting behind the wheel of the bus.

Police said 12 children were on board when Crain was driving. Zachary Superintendent Scott Devillier told News 2 all the children were safe, and that First Student is handling disciplinary action appropriately.

Investigators said drug tests were performed on Crain and samples were sent to the Louisiana State Police Crime Lab for analysis.

Crain was booked into the East Baton Rouge Parish jail and given a $7,200 bond.

Corporate Public Relations for First Student said they take student safety seriously and that Crain is removed from service until the completion of an internal investigation.
