DICKSON (AP) — The Tennessee Highway Patrol says alcohol was involved in the wreck of a fire truck that overturned on its way to a house fire.

The Tennessean reports (http://tnne.ws/2c6Gb5t) that the tanker truck carrying three Vanleer volunteer firefighters missed a turn Saturday morning and ran off of the road.

Driver David Boutcher told investigators the air brakes didn't work at the time of the crash.

The THP says Boutcher and another firefighter had been drinking alcohol before the wreck. Both were suspended and the THP said charges are pending.

The tanker had been on the way to a fire caused by a lightning strike. Another volunteer fire crew was already on the scene but the house was a total loss.

Vanleer is about 40 miles west of Nashville.
