CSA weights each of the BASICs safety violations for drivers and carriers based on severity. These severity weight “points” range from 1 to 10 with least serious violations rated a 1. Points get closer to 10 as they get more severe. Note that individual drivers do not receive any kind of “rating”, but their points contribute to their carrier’s CSA score. The same inspection and crash data that make up driver points on the carrier’s rating also show up as part of drivers’ PSP reports.
For the full listing of points, see the FMCSA’s document on SMS methodology, available at SMSMethodology.pdf.
