he Department of Public Safety is in the middle of a four-week enforcement action targeting trucks with safety problems in the counties that make up the Eagle Ford shale.

Trooper Jason Reyes, a spokesman for the department, said small towns in the Eagle Ford asked the state for help, after realizing they couldn’t handle the flood of truck traffic created by the oil boom. The heavy trucks are being blamed for crumbling roads in DeWitt County.

Reyes said the area’s infrastructure wasn’t ready for the dramatic increase in traffic, and that roads are quickly deteriorating, and fatal accidents involving commercial vehicles spiked significantly.

Reyes said Troopers are currently focusing their attention on state roads in Atascosa County. Troopers stop trucks they believe may be violating traffic or vehicle safety laws and order them to be inspected if they see anything out of the ordinary.

In three days of enforcement last week, nearly 400 trucks were inspected, with 40 of them placed out of service.

Reyes said the enforcement action has already cut down on accidents involving commercial vehicles.
