What sign could help motorist services find you on the expressway if you needed help?

Mile markers are critical for helping motorist services locate you on the expressway in case you need assistance. These markers are placed at regular intervals along the highway, typically every mile, and provide a numeric indication of your exact position on that road. When you contact emergency services or roadside assistance and give them the number of the mile marker you are located at, they can quickly pinpoint where you are, ensuring a more efficient response.

Exit signs, while useful for navigation, indicate the nearest exits rather than providing a specific location on the highway. Speed limit signs inform drivers of the legal speed but do not convey any location information relevant to emergency services. Warning signs are designed to alert drivers about upcoming hazards or changes in road conditions, but they too do not assist in identifying an exact location on the expressway. Therefore, mile markers are the best choice for helping motorist services find you.
