Final answer:
AQHA may allow exceptions to attire for medical or religious reasons by filing a request. This ensures inclusivity and allows participants to honor their health needs or religious practices while competing.
Step-by-step explanation:
The American Quarter Horse Association (AQHA) may make special exceptions to attire for two reasons: medical or religious. If a participant has a medical condition that necessitates attire adjustments or if their religious beliefs require specific clothing, they can file a request through AQHA to seek an exemption from the standard dress code regulations. This process is in place to ensure all participants feel included and can compete while honoring their health needs or religious practices.
