I will speculate these are requirements for an “Enhanced Drivers License.”
Here in Washington state, I have an “EDL” that allows me to travel to and from Canada, Mexico, Bermuda, and the Caribbean.
The requirements to obtain it were very strict.
It has not expired yet, so I don’t know anything about the Washington state renewal policy.
And, I think seniors, after a certain age, need an eye exam and must be able to hear and understand the clerk every 5 years, and there is also a long open space walk to the clerk's counter so they visually check your leg strength and mobility, too.
