USA

Bright yellow school buses are distinctive and appear only in the United States and Canada.

Interstate highways have green mile marker posts every 0.1 miles. Format: a number on a plain green sign.

American fire hydrants are squat, painted red or yellow, and placed on street corners.

Residential mail boxes are standardised: rectangular metal box on a post at the road edge.

Large single-story retail buildings with vast parking lots in front are a hallmark of American suburban landscapes.

The red-white-and-blue federal shield appears on all US interstate signs. Very distinctive.

American utility poles are typically wooden with multiple crossbars and bundled cables, more complex than European equivalents.

Each US state has its own distinctive road shield shape — California has a bear, Texas a cowboy hat, etc.
