WASHINGTON (DC News Now) — A D.C. school bus driver was charged with commercial DWI with child endangerment after police said the driver drove off the road during a field trip.

Police said that there were 44 kids and four adults on the bus at the time of the crash. The students were from Ben Murch Elementary School in D.C. and were visiting Cox Farms in Centreville.

Police arrested Troy Reynolds in Fairfax County during the field trip. They said his blood alcohol level was .20 — two times over the legal limit in Virginia.

Reynolds hit a rock after driving the bus off the road. School staff convinced him to pull over in a parking lot when police arrived. Officers said they could smell alcohol on his breath when they got there.

Police said that this was his second DWI in over two years. Two other bus drivers were also cited for not having a valid commercial license.

“The officers are looking at placing additional charges on the bus driver that was arrested for DWI, Reynolds,” Captain Rachel Levy with Sully District Station said during a conference Thursday evening.

DCPS Chancellor Lewis Ferebee released a statement on social media and said, “DCPS takes this incident very seriously, and our teams will do a thorough review of our transportation vendors to ensure that student safety is always prioritized.”

Another bus was called to take the students back home. That driver did not have the correct license to be driving the bus.
