What is the highest breath-alcohol limit that you can have and still compete?

To compete in motorsport events under the regulations set by MotorSport New Zealand, the legal blood alcohol limit for drivers is zero. This means that a competitor must not have any measurable blood alcohol content while participating in events. The rationale behind this strict limit is to ensure the safety of the driver, co-drivers, spectators, and fellow competitors, as alcohol can significantly impair motor skills, reaction times, and overall judgment.

In competitive motorsport, maintaining a completely sober state is crucial, as even minimal levels of alcohol can negatively impact performance and increase the risk of accidents. Therefore, adhering to a zero-tolerance policy regarding alcohol is essential for upholding high standards of safety and fairness in racing environments.
