Oregon Practice Traffic Signals

You have a steady green light at an Oregon intersection, but the traffic ahead has stopped and there isn't room for your vehicle on the far side. What should you do?

  1. A.
    Enter the intersection: your green light gives you the right of way.
  2. B.
    Enter slowly so you can clear the intersection as soon as the traffic ahead moves up.
  3. C.
    Wait behind the stop line until you can clear the intersection completely. Correct
  4. D.
    Enter and stop just past the crosswalk so you hold your place in line.
The Why

The answer is "Wait behind the stop line until you can clear the intersection completely."

Oregon's intersection rule is that even with a green light, you must not enter an intersection unless there is room for your vehicle on the other side. Entering and then stopping mid-intersection ("blocking the box") forces cross-traffic to wait when the light changes, creating gridlock and crash risk. Wait behind the stop line until you can clear the intersection in one continuous movement.

Why the others miss

The traps in the wrong answers

A. Enter the intersection: your green light gives you the right of way.

The manual's rule is explicit: even if you have a green light, do not enter an intersection unless there is room for your vehicle on the other side. Misreading: Treats a green light as unconditional permission to enter, ignoring the explicit "even if you have a green light" condition that requires room on the far side.

B. Enter slowly so you can clear the intersection as soon as the traffic ahead moves up.

Creeping in without room on the far side still leaves you stopped inside the intersection, blocking cross-traffic when the light changes. The rule requires room to exist before you enter, not after. Misreading: Reads the rule as satisfied by anticipated room: assumes traffic ahead will move up in time, when the manual requires room on the other side before you enter.

D. Enter and stop just past the crosswalk so you hold your place in line.

The rule prohibits entering the intersection itself without room on the far side, not merely blocking the crosswalk. Stopping just past the crosswalk still leaves your vehicle inside the intersection when the light changes. Misreading: Narrows the rule to the crosswalk: treats "do not enter an intersection" as if it only barred blocking the crosswalk, so a stop inside the intersection seems allowed.
