We here at the Advocate are starting to think it’s best not to get on a Dallas highway after midnight. After a drunk driver smashed into a broken down vehicle in the early hours of Saturday, Central Expressway saw another fatal accident at 2 a.m. this morning.

According to police, Dwyane Simon, 37, was under the influence of drugs as he drove his tractor truck up the highway. Without warning, he stopped in the middle lane of traffic under the I-635 interchange. Witnesses say Simons was wandering around the truck, seemingly incoherent. He left his massive vehicle sitting without emergency flashers, making it difficult for approaching motorists to see.

A Chevy Silverado pick-up truck traveling north did not expect the stopped vehicle, and plowed into the back of it, killing the unidentified driver.

Simon told authorities that his vehicle broke down, but police found that was not the case. After failing a field sobriety test, Simon was arrested on charges of intoxication manslaughter.
