SMS BASIC Scores Explained for Trucking Accident Attorneys

The Safety Measurement System (SMS) is the federal government's ongoing carrier safety scorecard. Every commercial carrier is scored on seven BASICs — Behavior Analysis and Safety Improvement Categories — based on roadside inspection and crash data from the past 24 months.

The Seven BASICs

Unsafe Driving (ALERT at 65th percentile) — Speeding, reckless driving, improper lane changes, and seatbelt violations. This BASIC directly measures driver behavior behind the wheel.

Hours of Service Compliance (ALERT at 65th percentile) — Violations of federal HOS regulations, including log falsification. HOS violations are the most potent liability indicator in trucking cases because they establish driver fatigue.

Driver Fitness (ALERT at 80th percentile) — Invalid CDL, missing or expired medical certificates, failure to maintain required qualifications.

Controlled Substances/Alcohol (ALERT at 50th percentile) — Drug and alcohol violations. The alert threshold is lower because even moderate rates indicate a serious carrier culture problem.

Vehicle Maintenance (ALERT at 80th percentile) — Out-of-service defects, brake violations, lighting failures. Brake violations combined with a Crash Indicator ALERT is a particularly strong pattern.

Hazardous Materials (ALERT at 80th percentile) — HazMat packaging, marking, and placarding violations. Only relevant for HazMat carriers.

Crash Indicator (ALERT at 65th percentile) — Crash frequency and severity compared to peer carriers. This is the most direct predictor of future crashes and the strongest liability indicator in the SMS system.
