Understanding This Report
Safety Rating is assigned after an FMCSA compliance review. “Satisfactory” means adequate safety controls are in place. “Conditional” means corrective action is needed. “Unsatisfactory” indicates a risk to public safety. Many carriers are “Not Rated” simply because they haven't been reviewed yet.
OOS violations are the most serious outcomes of a roadside inspection — the vehicle or driver is immediately taken off the road. A high OOS rate is a strong indicator of systemic maintenance or compliance issues.
