• Drivers and carriers must comply with HOS regulations.
• A fatigued driver is at risk of causing a crash.

An overly tired driver can be a danger to the public. That’s why the Federal Motor Carrier Safety Administration (FMCSA) takes fatigued driving and the hours-of-service rules seriously under the Compliance, Safety, Accountability (CSA) program.

The Hours of Service (HOS) Compliance Behavior Analysis and Safety Improvement Category (BASIC) is used to measure driver and carrier performance related to driving while ill, fatigued, or in violation of the hours-of-service regulations. Among the violations under this BASIC:

• Failing to complete or retain logs or use a required electronic logging device (ELD);
• Violating the HOS limits;
• Failing to include all required items on the log; and
• Violating an HOS-related out-of-service order.

Performance is measured using violations of certain Federal Motor Carrier Safety Regulations and state traffic control laws recorded on roadside inspection reports.
