Illinois Practice Road Markings

What do broken white lines between two lanes indicate?

  1. A.
    Opposite-direction lanes where passing is allowed.
  2. B.
    Same-direction lanes where lane changes are allowed. Correct
  3. C.
    A shoulder line at the road's right edge.
  4. D.
    A no-passing zone ahead.
The Why

The answer is "Same-direction lanes where lane changes are allowed."

Broken white lines separate same-direction lanes, and they may be crossed for a lane change or a turn. Choice A describes broken yellow; drivers who remember 'broken means passing allowed' mix up which color signals which direction of traffic.

Why the others miss

The traps in the wrong answers

A. Opposite-direction lanes where passing is allowed.

That describes broken yellow lines, which separate opposite-direction traffic. This answer confuses the color and pulls the passing rule from the yellow-line section.

C. A shoulder line at the road's right edge.

Shoulder lines are solid white on the right edge, not broken. This answer reads any white paint on the road as the pavement edge line.

D. A no-passing zone ahead.

No-passing zones are marked with solid yellow, not broken white. This answer pulls the no-passing meaning from the wrong side of the pavement-marking section.
