Texas is taking part in Roadcheck 2011 to make sure commercial truckers are driving safely and passenger buses are being operated properly.
The Department of Public Safety says the safety checks begin Tuesday and run through Thursday.
DPS during Roadcheck 2010 inspected 6,906 commercial vehicles, taking 25 percent out of service due to serious safety violations.
Troopers placed 160 of the drivers out of service for violations such as improper log books or having suspended, expired or canceled licenses.
The Roadcheck 2011 program also involves Mexico and Canada.
