A police escort rolled along with the cars to help with traffic management as drivers get used to seeing the streetcars rumble along.
Workers had to briefly shut down some roadways as they conducted tests on the streetcars and their power lines.
The crews also conducted short-circuit tests at each of the four power substations the day before.
Vehicles can drive in the same lane as the streetcar and it also has to obey all stoplights and traffic laws. Also, drivers shouldn’t turn in front of it from the center lanes – just like any other vehicle.
Each car is required to log 300 hours of on-track testing before its deemed safe. The streetcar is expected to begin service in September 2016.
