Please refer to section 3.7 of the Sporting Code, but in a nutshell:

3.7. SAFETY RATING 

• 3.7.1. Safety Rating (SR) is a value assigned to all racers as a measure of the driver’s overall safety record. It is calculated using a formula that takes into account the number of corners a driver completes and the number and severity of incidents that the driver accumulated in the process. These factors are averaged over a set number of laps and updated as each new Ranked session is finished. 
  • 3.7.1.1. Only Ranked Qualifying, Ranked Time Trial, Ranked Warm Up, Practice within a Ranked Race event, and Ranked Race events adjust competitors’ Safety Rating. All events not in this list do not adjust competitors’ Safety Rating. [See Sessions and Driver Ratings]. 
• 3.7.2. Each driver has their own Safety Rating for each License Class (ie: Rookie, D, C, etc.) and in each racing category (ie: Oval, Formula, etc.) ranging from 0.00 - 4.99. The higher the value, the safer the driver is for that class and racing category combination. 
• 3.7.3. Overlapping Values 
  • 3.7.3.1. License Classes: The values of Safety Rating for each License Class (ie: Rookie, D, C, B, A, and Pro) partially overlap with some of the values in the adjacent License Classes. For example, the lower portion of a B License Class overlaps with the upper portion of a C License Class. The amount of overlap is defined at a non-linear rate between each License Class. 
  • 3.7.3.2. Whole Number Ranges: The values of the measure of a driver’s overall safety record within each whole number range of a License Class (ie: 2.00 to 2.99) partially overlap with some of the values in the adjacent whole number ranges. For example, a lower portion of values within the 3.xx Safety Rating range overlap with an upper portion of values within the 2.xx Safety Rating range. The amount of overlap is defined at a non-linear rate between each whole number. 03 LICENSE CLASS - CONTINUED OFFICIAL SPORTING CODE // V.2025.09.09 10 
• 3.7.4. Any time SR increases or decreases across a whole number threshold, the value of the measure of a driver’s overall safety record is mapped into the new whole number range, with the fractional portion of SR being computed from where the value sits within that new range. For example, when your SR increases just beyond the 2.xx whole number range, it is mapped into the 3.xx whole number range, with the fractional portion of the new SR being computed from where it sits within the 3.xx range. Having this overlap helps to keep Safety Rating from bouncing up and down between whole number designations due to small changes to the measure of a driver’s overall safety record. 
• 3.7.5. Whenever you receive a License Class Promotion or Demotion (such as moving from D to C), the overall measure of your safety record is mapped into the overlapping whole number range within the new License Class. This can result in your Safety Rating number changing by a large or small amount, depending on where that measure sits within those ranges. Regardless of whether the visible change in your SR appears to be large or small, the measure of your safety record is not adjusted. This remapping allows the Safety Rating value to appear to remain on a simple 0.00 to 4.99 scale at all License Classes. 

3.8. MINIMUM SAFETY REQUIREMENTS

• 3.8.1. A driver must achieve and maintain a Safety Rating within a certain range to advance to the next License Class. A driver can track his or her safety record by the Safety Rating number on each racing category license. 
• 3.8.2. Drivers start with a Rookie License with a Safety Rating of 2.50 in all racing categories. As the driver completes Ranked race sessions safely, his or her Safety Rating will rise. Conversely, multiple incidents in Ranked race sessions will cause his or her Safety Rating to fall.
