During a calendar year, how many classes of competition can a driver compete in?

The reason a driver can compete in only one class of competition during a calendar year is rooted in the regulations designed to maintain fairness and consistency within the competition. Each class may have specific requirements, vehicle standards, and performance metrics that need to be adhered to. Limiting drivers to a single class ensures that they can focus on mastering the skills and techniques required for that particular class, enhancing the level of competition and allowing for a more standardized evaluation of performance among drivers.

Participating in multiple classes could potentially give some drivers an unfair advantage due to varied experience and skill levels required for different classes. Therefore, the regulation prioritizes fair play and allows for a clearer path to determine the best driver in each individual class without the complication of cross-class performance comparisons.
