Csa Basic Threshold Differences

Use this skill to understand why CSA BASIC alert thresholds differ across carrier types. Covers general freight (65th percentile), passenger/hazmat (60th), and the regulatory rationale.

BASIC Threshold Differences: General Freight vs Hazmat vs Passenger

The CSA Safety Measurement System (SMS) sets different intervention thresholds depending on what the carrier hauls. Same BASIC score can be alert-level for one carrier and clean for another.

Threshold table

Carrier type	Unsafe Driving	HOS Compliance	Driver Fitness	Controlled Substances	Vehicle Maintenance	Hazmat Compliance	Crash Indicator
General freight	65th	65th	80th	80th	80th	N/A	65th
Hazmat carrier	60th	60th	75th	75th	75th	60th	60th
Passenger carrier	50th	50th	65th	65th	65th	N/A	50th

Why the difference

Hazmat carriers handle materials that can harm public — tighter safety expected
Passenger carriers carry humans — tighter safety expected
General freight is property-only — wider tolerance

What "alert threshold" means

BASIC at or above the threshold percentile = alert
Triggers FMCSA intervention prioritization
Combined with crash history can trigger Compliance Review

How peer groups work

FMCSA assigns each carrier to a peer group based on:

Number of power units (vehicles)
Inspection volume
Time in operation

Peer group = pool of similar carriers. Your BASIC percentile is relative to your peer group.

Implications for owner-operator vs fleet

1-truck owner-operator: smaller peer group, more volatile percentile
50-truck fleet: larger peer group, more stable percentile
100+ truck fleet: largest peer group, most stable

Compass dashboard view

Compass CSA module shows your BASIC scores and the relevant threshold for your carrier type. Alert flags trigger when within 5 percentile points of threshold.

CFR citations

49 CFR § 385.4
FMCSA SMS Methodology

How Compass surfaces this

Searchable in Compass Ask. Runs against the carrier's actual fleet data when invoked from the relevant tracker. Read-only; no actions without explicit user approval.
