Two drivers escaped injury in a vehicle accident on I-40 in Roane County yesterday. A 2013 Ford F-150 driven by 30-year-old Joshua Helton of Oakdale lost control and struck a cable barrier at the 359 mile marker, came back onto the road and collided with a 2018 Volvo tractor-trailer operated by Simran Singh of California. The impact sent the Ford back into the cable barriers. Singh drove off the interstate and the tractor-trailer turned over on its side. Both drivers were restrained at the time of impact. The accident caused traffic delays for a couple of hours.
