What does the abbreviation MM refer to in a traffic or location context?

The abbreviation MM in a traffic or location context typically stands for Mile Marker. This designation is commonly used on highways and interstates to indicate specific distances along the route. Mile markers help drivers understand their location relative to the entire stretch of road, making it easier to provide directions, assess travel times, and report incidents or emergencies to authorities.

Recognizing mile markers is essential for efficient navigation and maintaining safety on roadways.
