1. What speed are Arizona roundabouts designed for?

Why: Arizona's Driver License Manual states roundabouts are designed for speeds of 15-20 mph — vehicles already circulating inside have the right-of-way, and an entering driver must yield to a large vehicle entering at the same time.

2. What is the purpose of a Diverging Diamond Interchange (DDI), used at some Arizona freeway interchanges?

Why: A Diverging Diamond Interchange briefly moves cross-street traffic to the left side of the road, guided by signals and pavement markings, so left turns onto the freeway on-ramps can flow freely without needing their own dedicated green-light phase.

3. Where can a driver legally cross the tracks of the Phoenix-area METRO light rail system?

Why: METRO light rail traffic in the Phoenix area only crosses at controlled, signal-equipped intersections — and U-turns are permitted at almost all of those intersections across the 20-mile system specifically to let vehicles cross the tracks safely.
