Abruptly turning into a corner to prevent a pass.
Flag requiring action on the part of the driver.

The first phase in handling a slide (CPR) is the "Correction." The driver looks where he would like to go and turns the steering wheel toward the direction that rear of the car is sliding.
driver`s Safety Rating is derived from their Corners Per incident (CPI) average. Each track has a set number of corners. For example Lime Rock Park has seven corners. If you get one incident point every lap, your CPI would be seven. If you drove 100 laps, with only one incident, your CPI would be 700.
A skid-control technique involving the Correction, the Pause, and the Recovery.
Gradually drifting toward the inside of the road and sacrificing radius on the approach to a corner. Crabbing is a symptom of low eyes and slow hand speed, and results in an early apex.
