📘 Key Compliance Areas

What Every Carrier Must Know

📋

Hours of Service (HOS)

Federal HOS rules limit how long a commercial driver can operate a vehicle before taking a required rest break. Property-carrying drivers are limited to 11 hours of driving within a 14-hour window after 10 consecutive off-duty hours. Violating HOS rules is one of the most common enforcement actions and can result in out-of-service orders and fines.

🛑

Electronic Logging Devices (ELD)

ELDs became mandatory for most commercial motor vehicle drivers in December 2019 under FMCSA regulations. An ELD automatically records driving time and hours of service data by synchronizing with the vehicle engine. Carriers must use FMCSA-registered ELDs from the approved device list. Drivers must carry ELD instruction sheets and malfunction reporting requirements.

🏷️

CSA Safety Scores & SMS

The Compliance, Safety, Accountability (CSA) program uses the Safety Measurement System (SMS) to identify high-risk carriers. Scores are calculated across 7 BASIC categories: Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials, and Crash Indicator. High scores can trigger FMCSA interventions and affect shipper relationships.

📝

Operating Authority (MC Number)

For-hire carriers must have operating authority from FMCSA before hauling regulated freight. You apply for a Motor Carrier (MC) number through the Unified Registration System (URS). New entrants must also complete a safety audit within the first 12 months of operations. Operating without proper authority is a federal violation.

⚖️

Drug & Alcohol Testing

FMCSA-regulated carriers must participate in a DOT-compliant drug and alcohol testing program. This includes pre-employment, random, post-accident, reasonable suspicion, and return-to-duty testing. Owner-operators must join a consortium. The FMCSA Drug and Alcohol Clearinghouse is a database that tracks drug and alcohol violations.

🔍

DOT Roadside Inspections

Commercial vehicles are subject to inspection at weigh stations, ports of entry, and roadside checkpoints. Inspections range from Level I (full driver and vehicle inspection) to Level VI (enhanced NAS inspection for radioactive cargo). Out-of-service violations require the vehicle or driver to stop operating immediately until the violation is corrected.
