Green sign with a white border and the white words EXIT 42

An exit number on a freeway sign is based on what?

  1. How many exits you have passed
  2. The speed limit on the ramp
  3. The size of the town at the exit
  4. The mile marker location of the exit
Show answer

Correct answer: The mile marker location of the exit

An exit number matches the mile marker where the exit is. It is not a count of the exits you pass.
