Unlike paper logbooks, which can be falsified or simply forgotten, truck hour-of-service monitoring records driving time, on-duty periods, and rest breaks automatically and tamper-proof – in many jurisdictions via a legally mandated ELD (Electronic Logging Device) or digital tachograph. The system continuously compares recorded hours against regulatory limits and alerts drivers and dispatchers before a violation occurs. This protects carriers from fines and liability at roadside inspections while directly supporting road safety by preventing fatigued driving. In the EU, drivers' hours are governed by road transport social regulations; in the United States, the FMCSA's Hours of Service rules set the applicable framework.
