Medical amnesty policy is a rule that says people who get help for someone who is very sick or injured won't get in trouble for breaking certain rules. For example, the rule might say that if someone is drinking alcohol and gets very sick or hurt, they can call for medical help without worrying about getting in trouble for drinking alcohol. It's like if you accidentally spilled milk on the floor and your mom told you not to worry about it, because you were trying to help clean it up.
The idea of medical amnesty is to encourage people to get help for others who need it without being afraid of getting into trouble themselves. This way, people can focus on getting help for someone who needs it, instead of worrying about getting in trouble. It's important to remember that medical emergencies can be very serious, so it's always better to ask for help if someone is hurt or sick, even if it means breaking a rule.
