The CSA Point System is based on an overall performance assessment called BASICs, which stands for Behavior Analysis and Safety Improvement Categories. The measure of each BASIC is determined by combining the time and severity of your violations. The BASICs cover more than 900 different violations within 7 categories: Unsafe Driving, Crash Indicator, Hours of Service (HOS) Compliance, Vehicle Maintenance, Controlled Substance/Alcohol, Hazardous Materials Compliance, and Driver Fitness. CSA scores do not include size and weight violations.
The severity of the alleged violation will affect your CSA score based on the 1-10 ranking. The timing of your violation will also affect it, with points being multiplied depending on the length of time since your last violation. Violations within six months of a previous violation result in 3x the points; violations within six to 12 months result in 2x the points; and those within 12 to 24 months remain at 1x the points. If a violation results in an Out-Of-Service Order (OOSO), 2 additional points are added to your score.
