We are asked to produce an identification document in so many places in our daily lives as proof of identity. These include, among others, airports, department stores, doctors office, hospitals, liquor stores, etc. etc.
In USA and most other countries, a driving license is accepted as a de facto proof of identity. Some people, especially while traveling in a foreign country, show their passports for identification purpose.
Sample California Driver's License
Something interesting happened about 2 years ago when we were traveling to Puerto Vallarta, Mexico, to attend a marriage. At the San Francisco Airport, we were asked to produce our identification card by the airport security. My wife showed her driver’s license. The security guy returned that and said “this is an expired license and I cannot accept it”. (My wife renewed her license a few weeks ago and kept both the old and new licenses in her purse. She should have discarded the old expired license. But did not.)
She said she is sorry and showed her renewed new license. The airport security accepted that and we were on our way to Puerto Vallarta.
I was pissed off at the airport security. But did not say anything or argue. There are some places it is better to keep quiet and grin f**k them and not invite any trouble. Airport security is one of them.
My point is why they would not accept an expired driving license as proof of identification. The valid authorization to drive a car may have expired but the information on that license (Name, Date of Birth, Address, Height, Weight, Color of Eyes, Color of Hair) do not expire, unless you were a Clark Kent then and now a Spiderman.
The airport security is supposed to verify your identity for the purpose of matching it to the ticket, i.e. name match. Where does it say it has to be a non expired license?
I am thinking of writing a letter to my Senator to change the law if there is such a law. Most of the times these “authorities” will not accept an expired license for identification purpose.
