Driver's License Test Prep
Florida Practice Guide Signs

A two-digit Florida interstate route shield carries an odd number. What does the number tell you about the route?

  1. A.
    It is a toll route
  2. B.
    It runs North-South Correct
  3. C.
    It is a loop route
  4. D.
    It runs East-West
The Why

The answer is "It runs North-South"

Two-digit odd numbers mark North-South interstate routes; even numbers mark East-West. Reversing that pairing after locking only one side of it into memory leads to choice D.

Why the others miss

The traps in the wrong answers

A. It is a toll route

Route numbers do not encode toll status. This answer treats route numbering as a code for road type rather than for compass direction.

C. It is a loop route

Loop and spur routes use three-digit auxiliary interstate numbers; the two-digit shield in this question carries compass direction instead. This answer guesses loop as the only non-directional interstate label the reader can name without knowing what odd digits actually signal.

D. It runs East-West

East-West routes carry even numbers, not odd ones. This answer reverses the even/odd pair after locking only one side of it into memory.
