Average PU × Utilization Factor (as of 12/26/2025, updated monthly)

The SMS normalizes the Unsafe Driving and Crash Indicator BASICs measure by carrier size (i.e., a hybrid power unit and vehicle miles travelled measure) to account for exposure. Carrier size is defined as average power units multiplied by the utilization factor.

23.3 Average PU × Utilization Factor = 23.3 Average Power Units × 1 Utilization Factor

Average Power Units
Utilization Factor

In order to account for changes in a carrier's fleet size during the previous 24 months an average power unit value is used in the calculation to determine a carrier's Unsafe Driving BASIC and Crash Indicator measures.

23.3 Average Power Units = 22 Current Power Units + 24 Power Units 6 Months Ago + 24 Power Units 18 Months Ago
3

The Utilization Factor is a multiplier that adjusted the average PU values based on the utilization in terms of VMT per average PU.

Determine Carrier Segment: Combo
Combination trucks/motor coach buses constituting 70% or more of the total PU
U.S. DOT# 40205 = 100% Combination trucks/motor coach buses
Determine VMT per Average Power Unit
54,507 VMT per Average Power Unit = 1,271,668 VMT From Investigation (MCS-151) ÷ 23.3 Average Power Units

Based on Step 1 and 2 calculate the Utilization Factor

Combo Segment
Meets Criteria	VMT per Avgerage PU	Utilization Factor
	< 80,000	1
	80,000 – 160,000	1 + (VMT per PU − 80,000) ÷ 133,333
	160,000 – 200,000	1.6
	> 200,000	1
	No Recent VMT Information	1

Use of SMS Data/Information

FAST Act of 2015:

Readers should not draw conclusions about a carrier's overall safety condition simply based on the data displayed in this system. Unless a motor carrier has received an UNSATISFACTORY safety rating under part 385 of title 49, Code of Federal Regulations, or has otherwise been ordered to discontinue operations by the Federal Motor Carrier Safety Administration, it is authorized to operate on the Nation's roadways.

Safety Measurement System:

The data in the Safety Measurement System (SMS) is performance data used by the Agency and Enforcement Community. A symbol, based on that data, indicates that FMCSA may prioritize a motor carrier for further monitoring.

The symbol is not intended to imply any federal safety rating of the carrier pursuant to 49 USC 31144. Readers should not draw conclusions about a carrier's overall safety condition simply based on the data displayed in this system. Unless a motor carrier in the SMS has received an UNSATISFACTORY safety rating pursuant to 49 CFR Part 385, or has otherwise been ordered to discontinue operations by the FMCSA, it is authorized to operate on the nation's roadways.

Motor carrier safety ratings are available at http://safer.fmcsa.dot.gov and motor carrier licensing and insurance status are available at http://li-public.fmcsa.dot.gov/.
