I was driving today and stopped at a stop sign waiting for a garbage truck to pass, but then it turned on its blinker and turned right. I noticed that both the passenger AND driver side had steering wheels and both were turning their steering wheels. How does that work???

My son is a garbage man and has worked for many years driving a variety of trash related vehicles.
For safety reasons, they use the left side when driving into main streets etc, while in urban neighborhoods they use the right side drive. This gives better visibility to objects on the right side of the vehicle.
What you saw was a helper and a driver both in the vehicle. If it was a major street the person on the left was driving the vehicle and the helper was driving along.
