Who enforces HOS rules?

HOS regulations are primarily enforced by:

• Federal Motor Carrier Safety Administration (FMCSA): Sets and monitors compliance standards for interstate carriers.

• State Enforcement Agencies: Inspect HOS compliance during roadside checks and at weigh stations.

• Law Enforcement Officers: Issue citations for HOS violations during inspections or after traffic stops.

Enforcement methods include:

• Roadside Inspections: Officers review logbooks or ELD records to ensure compliance.

• Carrier Audits: FMCSA conducts audits to evaluate company adherence to HOS regulations.

• Data Analysis: Compliance and Safety Accountability (CSA) scores identify carriers with frequent violations.

Penalties for non-compliance range from fines to out-of-service orders for drivers and carriers.
