• Relevant violations recorded during roadside inspections are used in the HOS Compliance BASIC (Behavior Analysis and Safety Improvement Category) Methodology.

The Hours-of-Service (HOS) Compliance BASIC addresses the operation of commercial motor vehicles (CMVs) by drivers who are ill, fatigued, or in non-compliance with the HOS regulations. This BASIC includes violations of regulations surrounding the complete and accurate recording of log books as they relate to HOS requirements and the management of CMV driver fatigue.

The HOS Compliance BASIC does not include incidents where unconsciousness or an inability to react is brought about by the use of alcohol, drugs, or other controlled substances. Violations under this BASIC include HOS, logbook, and operating a CMV while ill or fatigued.

HOS Compliance BASIC data sources

The HOS Compliance BASIC uses relevant violations of the safety regulations recorded by enforcement personnel during roadside inspections and entered into SAFETYNET and channeled into the Motor Carrier Management Information System (MCMIS) .

Roadside inspections are examinations conducted by a Motor Carrier Safety Assistance Program (MCSAP) inspector on individual commercial motor vehicles and drivers to determine if they are in compliance with the Federal Motor Carrier Safety Regulations (FMCSRs) . Inspection data are taken from MCMIS.

Violations are recorded during inspections and entered into the MCMIS database. (Note: If a driver is cited and convicted of a violation related to an HOS Compliance BASIC safety regulation, but it does not appear on the roadside inspection report, it will not be entered into MCMIS. It will appear on the driver’s motor vehicle report (MVR), but it will not be factored into the carrier’s BASIC Score.)
