Final answer:
Persons can indicate their intent to become an organ donor when obtaining, renewing, or updating their driver's license or ID card. This process is typically handled by the Department of Licensing or its equivalent in the state.
Step-by-step explanation:
A person can inform the Department of Licensing (DOL) of their wish to become an organ donor at any time they are interacting with the department, particularly when obtaining, renewing, or updating their driver's license or state identification card. While Oregon's automatic voter registration system, referenced in the context provided, updates voter rolls when a citizen moves and updates their license, the process for registering as an organ donor can also occur during these regular DOL interactions. However, specific rules regarding when and how one can opt in to be an organ donor can vary by state, so it's advised to check with the local DOL for the most accurate information.
