A local man was killed in a fiery crash Friday morning on Interstate 40 in Knoxville when his vehicle slammed head-on into an oncoming tractor trailer.The victim, Scott Lakeland (Lake) Hankdal, 24, apparently entered the interstate going the wrong way during the pre-dawn hours Friday morning, a mistake which had been made by others before in what some locals there call a confusing on-ramp. Hankal had recently moved to Knoxville.According to preliminary reports on the crash, the accident happened around 2 a.m. Friday when Hankal entered the westbound lanes of I-40 near the Cherry Street exit in his Dodge pick up. The driver of the tractor trailer, who suffered non-lifethreatening injuries, said he saw the vehicle coming toward him and tried to swerve to the right.
