What do lane signals with a yellow X indicate?

  1. The signal is about to change to a green arrow.
  2. The signal is about to change to a red X. ✓
  3. Drivers may drive normally in this lane.
  4. Drivers may drive slowly in this lane.

Answer: B. The signal is about to change to a red X.

A yellow X means the lane signal is about to change to a red X.

Why this is the answer

The handbook's lane signal section lists three lane-signal meanings. A red X means you must never drive in that lane. A yellow X warns that the lane's signal is getting ready to go red. A green arrow means you may use the lane and must still obey other signs and signals. Since the yellow X is tied directly to the coming red X, the correct choice is the one saying the signal is about to change to a red X, not one that treats the lane as open.

Why the other answers are wrong

Remember it

Treat a yellow X as a warning, not a permission slip: red X comes next.
