HOS Compliance BASIC
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
Hours-of-Service Compliance is the CSA BASIC that aggregates HOS-related violations recorded at roadside inspections - most commonly false log entries, ELD malfunction or non-use, exceeded 11/14/70-hour limits, and inadequate sleeper-berth records. It is the highest-frequency violation category at roadside (about 30% of all citations). Severity weights run 1 to 10. Carriers with elevated HOS percentiles should focus on three remediation areas: ELD compliance verification, driver retraining on the 14-hour clock, and dispatcher training on load planning that respects available driving hours.
