In California, instead of taking the test at the DMV, you can take an easy tutorial type class online. Last year, DMV did not send me a renewal notice (they acknowledged it, but didn't know why.) So my license actually expired, before I noticed it, and I had to take a test and bring in several documents proving who I am, to renew. I did the online class in-lieu of the test at DMV. I thought it was super easy, but the clerk told me that some seniors can't pass the online class - it's a tutorial, so I can't imagine why not, but maybe it's related to computer proficiency.
Need to take a driver's license knowledge test? You can now take it online!
