"Be careful not to confuse "street" and "road"!"
I honestly don't know the difference, and use the words interchangeably.
I actually feel like we wouldn't use street in a rural setting...streets are more for cities and roads are for the countryside.
Me either, but if I had to guess it is based on relative traffic. Highway > road > street.
Road and street are pretty much the same and used interchangeably.
I'm going to report this as a mistake as I agree with all comments. Maybe Duo will correct it.
