Here's a photo that reminds us why we are happy working in these mechanized times.

It might be a sign of the times or it might just be a busy area! Join or weekly "Where in AZ??" challenge.

Our fourth Safety Message Contest has wrapped up, so we are looking back at the start of the annual contest and past winners.

The latest annual Arizona vehicle crash data tells us about the most common type of collision - and how some simply changes to driving behavior can help change that.

Though ADOT cannot reduce the number of crashes that happen on Arizona roads by itself, our director talks about what we are doing to make sure everyone gets Safely Home.

National Cleanup Day happens in one month, so now is the time to tell us you'll be there!
