UPDATE: One person seriously injured in multi-vehicle crash on DNT in Plano

At around 6:45AM this morning, Plano Fire-Rescue and DPS Troopers were called to the scene of a major accident along southbound Dallas North Tollway near Park Blvd.

Truck 5, Engine 5, and Medic 7 advised one person was trapped in one of the vehicles. The person was reported to be unconscious and seriously injured. Firefighters extricated the occupant and transported to the hospital with serious, potentially critical, injuries.

DPS troopers say a smart car was southbound on the Dallas North Tollway when it entered slowing or stopped traffic. For an undetermined reason, the driver of the smart car took evasive action and swerved out of its lane, hitting another vehicle in the process. The smart car struck the center median and was then impacted by a pickup truck.

The driver of the smart car was the one who was trapped and seriously injured. No other drivers were injured in the crash.

The crash is under investigation at this time. All southbound lanes of the Dallas North Tollway are closed.
