Mile markers are signs placed along roads and highways that indicate the distance traveled from a specific starting point, usually a city or a state line. They help drivers gauge how far they have traveled and how far they have left to go. Each marker typically shows the number of miles from the starting point, making it easier for travelers to plan their journeys. In addition to providing distance information, mile markers can also assist emergency services. If a driver needs help, they can report their location by referencing the nearest mile marker, allowing responders to find them more quickly. This system enhances safety on the roads.
