ODOT's "Roadcheck 2011" is underway. Sally Ridenour with the agency says inspectors are mainly focused on driver logbook violations.  Because drivers are only allowed to spend so much time driving each day; they sometimes won't keep records the way they're supposed to. Drivers are being checked at weigh stations throughout the state through Thursday.  Typically, if they're found in violation they are placed in out of service until they take a proper break or fix another safety violation.
