Is it a Bus or a Garbage Truck?

I have never had trouble distinguishing a bus from a garbage truck until I walking between bus stops at twilight looking back down the street for about 3 blocks and had to determine if the large greenish vehicle at the stop light with the running lights above the windshield was a bus a little ahead of schedule (so run to the next bus stop) or a garbage truck making its rounds (so continue sauntering to the next bus stop). Because I could not see the bus route number, I decided it was a garbage truck only to watch the garbage truck drive by followed immediately by my bus.

It was a good day for a walk.
