Highway Trivia Mile Markers

Ever wondered what those little green signs with numbers along the highway meant? Those are called mile markers and we’ll explain the significance of them along with some fun highway trivia questions in this week’s blog post.

Mile Markers are usually green with white numbers and the word Mile. These mile markers reflect how many miles from where the Interstate route entered the state you are traveling in. The numbers start at the state line in the south for North and South routes and in the west for East and West routes. They increase as you travel east or north and decrease as you travel west or south.

What do mile markers tell us?

• Exactly where we are.
• How far away your destination is.
• Your location if you have to call for roadside assistance.
