What is the rating for a car that swerves 12 inches or less due to driver error during a brake test?

The rating of Fair is indicative of a situation where a vehicle exhibits some level of control during a brake test despite some driver error. In this context, swerving 12 inches or less suggests that while there was a loss of precision in driving, the vehicle remained largely manageable and did not veer significantly off course. This degree of swerving implies that the brakes are functioning well enough to keep the car mostly within safe parameters, but the driver's error prevented it from achieving a higher rating.

In contrast, a rating of Good or Excellent would suggest minimal or no swerving, indicating strong driver control and excellent braking performance. A Bad rating would indicate significant swerving beyond the 12 inches threshold, reflecting poor handling and potential issues with vehicle stability during braking. Therefore, the Fair rating appropriately reflects a moderate level of performance under the given conditions.
