California DMV Permit Test (Class C)Traffic Signs and SignalsHard

You are driving on a road and see a traffic signal that is a steady yellow 'X' above your lane. What does this signal mean?

  1. AThe lane is closed to all traffic in your direction.
  2. BThe lane is open for traffic, but proceed with caution.
  3. CYou must exit this lane as soon as it is safe to do so.
  4. DYou may proceed in this lane only if you are turning left.
Show answer & explanation

Correct answer: C. You must exit this lane as soon as it is safe to do so.

A steady yellow 'X' indicates that the use of the lane is changing, and you must safely move out of the lane as soon as possible. It is a warning that the lane will soon be closed or its direction reversed.

Why the other options are wrong

  • A. A steady red 'X' indicates the lane is closed. The yellow 'X' is a transition signal, warning of an impending closure.
  • B. A steady green arrow or a simple green light indicates an open lane; a yellow 'X' indicates a change is imminent.
  • D. Lane use signals are general for the lane, not specific to a turn unless accompanied by an arrow.

Steady Yellow 'X' Lane Use Signal

A traffic signal displaying a steady yellow 'X' above a lane, indicating that the lane is about to be closed or its direction reversed, and drivers must prepare to safely vacate the lane.

  • Warning signal of an impending change in lane availability.
  • Requires immediate action to move to an open lane.
  • Precedes a steady red 'X' or a change in lane direction.

Memory trick: Green is go, yellow is change, red is stop, flashing means caution.
