INSPECTION: Pennsylvania State Police Trooper Paul Gaspich conducts a commercial motor carrier inspection by checking a trucker's log book along Interstate 81 in Grantville. Despite a half decade of tougher enforcement measures, authorities say too many truckers regularly break rules limiting how long they can be behind the wheel before they must pull over and rest.
LOG BOOKS: Some truckers run two log books -- one to show to state troopers if they get pulled over and one to keep for themselves that lists their real hours.
