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.
The measurement for each BASIC depends on
Number. How many violations (or crashes) were there?
Severity. How bad were they?
Recency. How long ago did they happen?
Measures are time weighted, meaning the more recent the violation, the more points the driver and carrier get. Here’s how it works:
Points Example: At an inspection, Driver Dan is found to he driving a truck using a suspended CDL and is placed out of service. For this violation, both Dan and his employer receive 10 points, which are then time-welghted. For 12 months after the inspection, Dan has 30 points assigned to his score (10 points multiplied by 3). Dan’s employer has 30 points assigned to its score for six months as well. Eighteen months later, Dan would have 20 points assigned to his score (10 points multiplied by 2) and his employer would have 10 (no multiplier).
