Safety Violations
The below safety violations are the Safety Measurement System's (SMS) BASIC violations released monthly by the FMCSA. Hey Bubba! updates these statistics as they are released by the FMCSA.

	Total	Severe	Measure For each BASIC violation category, the SMS calculates a quantifiable measure of a motor carrier's performance. These scores are provided by the FMCSA, and Hey Bubba! updates the measure each month as they are released by the FMCSA.	Percentile The percentile scores provide context for the BASIC measurements of the carrier when compared against the measurements of other active carriers, assigning them a percentile from 0 - 100 (the higher percentile, the worse the percentile score). These scores may differ slightly to other carrier databases (including percentile scores assigned by the FMCSA but not available to the public). The percentiles assigned by this system are not an endorsement by Hey Bubba! of who is or is not a safe motor carrier, it is simply to provide context for the BASIC measures. Readers are encouraged to review Sections 5221 and 5223 of the FAST Act related to the FMCSA CSA program and the use of this data.

Safety Rating
This is a measure of the carrier's compliance with the Federal Motor Carrier Safety Regulations (FMCSR). A Compliance Review is a statistical sampling or audit of required records to determine a motor carrier's compliance with the FMCSR. An in-depth review of the motor carrier's records is made to check different categories of drivers, vehicles and trips. This review may be limited to specific problems and may include a detailed investigation of a problem area. The compliance status determination is based on FMCSR violations discovered during the review. The below safety rating information is based on SAFER Web data.
