New York Practice Traffic Lights

A flashing yellow X is lit on a lane-use control light above your lane. Under the manual, what does it mean?

  1. A.
    You may use this lane normally.
  2. B.
    Do not drive in this lane.
  3. C.
    This lane is for left turns only. Correct
  4. D.
    Move out of this lane.
The Why

The answer is "This lane is for left turns only."

Lane-use control lights hang above the pavement and tell you which lanes are open right now. A flashing yellow X keeps the lane open, but only as a left-turn lane. Drivers who pick option D are reading the flashing yellow X as a softer form of the steady yellow X (move out of this lane), the way a flashing yellow traffic light softens a steady one; the flashing X changes what the lane is for, not whether you should leave it.

Why the others miss

The traps in the wrong answers

A. You may use this lane normally.

That is the green arrow. A flashing yellow X restricts the lane to one movement rather than opening it. This answer carries over the regular flashing yellow traffic light meaning (drive with caution) to the lane-use control light and reads it as general permission.

B. Do not drive in this lane.

That is the steady red X, not the flashing yellow one. A flashing yellow X still keeps the lane open. This answer applies the steady red X's meaning to any X on a lane-use light, treating flashing yellow as an intensified prohibition rather than a permitted movement.

D. Move out of this lane.

That is the steady yellow X. A flashing yellow X does not order you out of the lane. This answer reads the flashing yellow X as a softer form of the steady yellow X, the way a flashing yellow traffic light softens a steady one.
