Final answer:
Mile Marker signs on highways indicate the distance from a reference point, helping drivers navigate long distances and estimate travel time.
Step-by-step explanation:
Mile Markers signs are commonly found on highways and roads to provide information about the distance from a specific location. They typically indicate the number of miles from a starting or reference point, such as the beginning of the road or a major intersection. For example, a mile marker sign with the number '50' means that you are 50 miles away from the reference point.
These signs are helpful for navigation, especially during long-distance travels. They allow drivers to estimate the distance they have traveled or the distance remaining to their destination. By keeping track of the mile markers, drivers can plan rest stops, estimate travel time, and measure progress along their route.
