Anyone who drives the highways has seen milepost markers, those little green signs with white numbers. Perhaps you have used them to check your odometer's accuracy or to give someone directions.

You can find the answers to questions you might have about these information signs in an article called "What Do Those Milepost Markers Tell You?" from our Road Travel Getaways journal.
