Driver's License Test Prep
Illinois Practice Turning

You entered an intersection on a green light to make a left turn, and the light turns red before you can complete the turn. What should you do?

  1. A.
    Continue straight and turn at the next block
  2. B.
    Back up out of the intersection
  3. C.
    Wait in place until the light turns green again
  4. D.
    Yield to oncoming traffic and complete the turn Correct
The Why

The answer is "Yield to oncoming traffic and complete the turn"

Once you enter the intersection on a green light, you may finish the turn after the light turns red, yielding first to oncoming traffic. Backing out of the intersection feels safer to some drivers, but the manual treats the movement you have already started as one you may complete.

Why the others miss

The traps in the wrong answers

A. Continue straight and turn at the next block

Abandoning a turn in progress is not one of the allowed responses. This answer turns the situation into a fresh choice at the next block rather than completing the movement already begun.

B. Back up out of the intersection

The manual allows you to finish the turn once you have entered on green. This answer reaches for a reversal as the safer option, unaware that finishing the turn is what the rule allows.

C. Wait in place until the light turns green again

The red light does not trap a car that has already entered the intersection. This answer reads the red signal as a hard stop even after entry, missing the finish-the-turn exception.
