Suspected drugged trucker arrested for manslaughter after parking on highway “for no apparent reason”

Witnesses say the truck driver was incoherent.

Just around 2:30 a.m. on Tuesday morning, a truck driver stopped his truck in the middle lane of U.S. 75; moments later, a carr driver crashed into the back of the truck and was killed.

The truck driver, Dwayne Simon, 37, did not put his flashers on or properly indicate whatsoever that his truck was stopped in the middle of the interstate.

The other driver was driving a Chevy Silverado when it smashed into the back of the immobile truck.

The killed Chevy driver has not yet been identified, according to local police.

Police closed U.S. 75 for approximately 4 hours in order to thoroughly investigate the scene of the accident.

Witnesses of the accident told police that Simon got out of the cab and began pacing around the truck, apparently incoherent.

Simon told Dallas Police Department officers that he had to stop the truck because it was experiencing mechanical problems that made it impossible to continue driving the truck.

At the scene, police conducted a sobriety test. Simon was under the influence of drugs at the time of the crash, according to the Dallas Observer. 

Police also later discovered that there were no mechanical issues with the truck at all.

Simon was charged with intoxication manslaughter and booked him into Dallas County Jail at 6:45 a.m. No bail has been set.
