CSA BASICs - Hours of Service Compliance

Driving CMVs when ill, fatigued, or in violation of the hours-of-service (HOS) rules. This is distinguished from incidents where unconsciousness or an inability to react is brought about by the use of alcohol, drugs, or other controlled substances. Data includes HOS violations discovered during an off-site investigation, on-site investigation, roadside inspection, or post-crash inspection and crash reports with driver fatigue as a contributing factor.
