Aside from regular traffic safety laws established by each state, truck drivers and trucking companies must also comply with many federal safety rules and regulations. Truck drivers must maintain logbooks to record the hours they spend behind the wheel, comply with driving time restrictions, perform routine vehicle inspections and comply with load weight limits. Furthermore, trucking companies must maintain their vehicles on a regular schedule in order to ensure the safety of their drivers, as well as other people on the roadway. Both federal and Ohio trucking regulations may apply in your case.
