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.
