In the Only in California department in a State that has banned texting and talking on cell phones, the California Department of Motor Vehicles has an iPhone app with GPS that finds a DMV office and also tells you how long you are going to wait in-line!
With the CA DMV iPhone app, you can watch educational driving videos with captions. You can also get important DMV alerts (hopefully not while you are driving.) Users can study and take written drivers tests.
The California Department of Motor Vehicles iPhone app is free and available via iTunes. This app can definitely be handy because many DMV offices are closed on the first three Fridays of every month due to t budget cuts. Unfortunately, the app won't wait in line for you. According to specs it will work on the iPad too.
