Oregon Practice Warning Signs

You see the Two-Way Traffic Ahead warning sign. What does it specifically tell you?

Yellow diamond with two straight black arrows side by side, left arrow pointing down and right arrow pointing up
  1. A.
    A two-way left turn lane begins ahead
  2. B.
    Cross-traffic may enter the road from a side road
  3. C.
    A divided highway with separated lanes begins ahead
  4. D.
    A one-way road is ending, and you will face oncoming traffic ahead Correct
The Why

The answer is "A one-way road is ending, and you will face oncoming traffic ahead"

The Two-Way Traffic Ahead sign appears where a one-way road ends and joins a two-way road, meaning you will face oncoming traffic ahead. Its job is to warn drivers leaving a one-way segment that the directional flow is changing, not to announce two-way traffic in general. Answer C swaps in the neighboring Divided Highway Begins warning, blurring two adjacent yellow figures about lane configuration into a single message.

Why the others miss

The traps in the wrong answers

A. A two-way left turn lane begins ahead

A two-way left turn lane is signed with regulatory, not warning, signs. This answer confuses a yellow warning sign with the white regulatory Center Lane Turn Only sign for a two-way left turn lane.

B. Cross-traffic may enter the road from a side road

Cross-traffic from a side road is shown by the Side Road or Crossroad sign. This answer confuses the Two-Way Traffic Ahead sign with the Crossroad or Side Road warning signs that flag entering cross-traffic.

C. A divided highway with separated lanes begins ahead

A divided highway beginning is shown by the Divided Highway Begins sign. This answer confuses the Two-Way Traffic Ahead sign with the separate Divided Highway Begins or Ends warning sign.
