At 3:27 AM, CHP and San Jose FD responded to reports of a vegetation fire off the side of the Southbound 280, near McLaughlin. Initial responding units arrived to find approximately 1/4 acre of brush on fire along the side of the freeway. It took firefighters a few minutes to put the fire out. There have been numerous vegetation fires in the brush along both sides of 280 in this area over the last 2 months.
