In addition to the scores for each maneuver, a large variety of penalties may be assessed for specific infractions. Penalties may range from a half-point (1/2) to five (5) points for each infraction, and in some cases a significant error may result in a zero score (0) for the run. Certain misbehaviors may incur penalty points beyond a poor score for a given maneuver. Significant errors, such as going off pattern or using illegal equipment, will result in a "zero score". Under NRHA rules, horses with a zero score cannot earn a placing or advance in a multi-go event, though they may be eligible for a payout if there is a small number of horses in the entire competition. Some sanctioning organizations other than NRHA may allow a horse in a small class to earn an award for last place. Major mistakes, such as failure to present the horse for an equipment check, a rider with illegal equipment or one who abuses the animal in specified ways, result in a "no score," which prevents the horse from earning any award or payout, even if it is the only horse in the class.
