The incident occurred at approximately 12:55 a.m. when the red 2014 Freightliner fire truck experienced a mechanical failure while making a right-hand turn, causing the vehicle to lose control and overturn. The truck came to rest upside down in the northbound ditch.

No other vehicles or individuals were involved. Drugs or alcohol were not factors in the crash. The vehicle was totaled. The cause of the incident remains under investigation.
