Final answer:
Generally, it is true that indicating donation wishes on a driver's license adds a person's name to an organ and tissue donor registry, but details can vary by region.
Step-by-step explanation:
The statement that all people who indicate their donation wishes on their driver's license will have their name added to the legacy organ and tissue donor registry can be generally considered true. However, the process of registration and eventual donation may vary by region and country. In the United States, for example, when a person opts to be an organ donor through their driver's license, they are typically registered with a state donor registry. Still, it is advisable for individuals to check with their local Department of Motor Vehicles (DMV) or a similar authority and the organ donation registry in their area for specific policies and procedures.
