A lunchtime collision in a parking lot Thursday left a portion of Princeton without power.

The incident occurred just before 12:30 p.m.

Princeton Police Chief Chris King said an Estes Express Lines tractor-trailer driven by Casey L. Riggs, 35, of Benton was attempting to leave the parking lot behind the law office of Vance Cook at 120 E. Main St. when it struck low-hanging utility lines. The tension on the wires snapped a utility pole supporting the lines and a transformer, causing it to fall onto a parked Phelps Electric service truck.

The owner, Austin L. Phelps, 27, of Princeton was inside the vehicle at the time, but was able to escape before the transformer burst into flames. The pickup sustained heavy damage to the front end from the impact and fire.

Another parked vehicle and buildings suffered damage as well.

King reports the power was out to portions of downtown Princeton for about an hour.

City police officers were assisted at the scene by Princeton Fire Department.
