Firefighters were kept busy early Friday morning, first responding to a fire in an empty house in Talent and then to a fire on Interstate 5 that destroyed several vehicles being transported on a car-hauler truck.

Investigators were working to determine the cause of a two-alarm blaze that destroyed the empty house in the 900 block of Suncrest Road. A driver on I-5 spotted the flames and made the first 9-1-1 call reporting the fire at about 3 a.m., Jackson County Fire District No. 5 Capt. Jim Campbell said.

The first firefighters to arrive found the unoccupied house engulfed in flames, he said. The Phoenix Fire Department and Ashland Fire and Rescue assisted District 5 crews, and the Medford Fire Department brought a water tanker to the scene of the fire, officials said. Fire departments around the Rogue Valley also were activated to move up and protect other districts.

Crews remained at the house fire when they got another call at 4:38 a.m. Friday reporting a truck fire at milepost 5 on I-5 south of Ashland. A car-hauler carrying nine vehicles caught fire and "burned rather well," Campbell said.

District 5 firefighters were joined by crews from the Colestin Valley Fire Department, and the Oregon and California departments of forestry. They saved five of the nine vehicles on the trailer, Campbell said.
