Driver location sign

Have you ever been on a big highway and seen a big green sign with lots of numbers and letters on it? That sign is called a "driver location sign". It's like a map that tells drivers exactly where they are on the highway.

So, if you're driving and you see a sign that says "Mile 10", it means you have traveled 10 miles on that highway. The signs also show you which direction you are heading, like "North" or "South".

But that's not all! The signs can also help you in case you need to call for help. For example, if your car breaks down, you can use the numbers and letters on the sign to tell the tow truck company exactly where you are. They can use that information to find you quickly and easily.

In summary, a driver location sign is a big green sign on the highway that tells drivers where they are, which direction they are heading, and can be used to give their location in case of an emergency.
