Lighted triangular craft seen north of waco tx.While driving south on hwy 35 from Dallas To Waco at 0030 in the morning on wednesday, in the area approx. three miles north of elm mott or about twelve miles north of Waco I saw a single triangular shaped craft cross the hwy approx. 1\4 of a mile in front of my truck. The craft was traveling from the west over the hwy towards the east at about three hundred feet in altitude. It then decended to approx. two hundred feet and made a ninety degree turn to the south.When it made this turn it did so abruptly yet only apeared to roll about three degrees from the horisontal while doing so. The craft had a width that I estimate at 70ft it was traveling at aprox. 150 kts. And was in view for about 1.5 minutes. In addition the whole unerside was lit up with lights. There also apeared to be two dim lights that resemble anti collision lights seen on military aircraft. Even tho I had the window down I could hear no sound above the road noise.
