Illinois Practice Road Markings

Yellow or white diagonal stripes painted on the pavement are used to mark:

  1. A.
    School crossings.
  2. B.
    Bicycle lanes.
  3. C.
    Fixed obstructions. Correct
  4. D.
    Passing zones.
The Why

The answer is "Fixed obstructions."

Diagonal stripes flag fixed obstructions such as barriers or medians. Choice A reaches for the yellow-green association with school signs and transfers it to pavement paint, where the color has a different job.

Why the others miss

The traps in the wrong answers

A. School crossings.

School crossings are indicated by a five-sided yellow or yellow-green sign, not pavement stripes. This answer transfers the school-zone sign color to pavement paint.

B. Bicycle lanes.

Bike lanes are marked by solid boundary lines, not diagonal stripes. This answer mixes obstruction markings with the bike-lane paint scheme.

D. Passing zones.

Passing zones are shown by broken yellow center lines, not by diagonal stripes. This answer reads yellow stripes as a passing signal, borrowing the meaning from the center-line color.
