Driver's License Test Prep
Oregon Practice Lane Changes & Merging

You're driving on an Oregon multi-lane freeway in the right lane and another vehicle is signaling to enter from an on-ramp. What does the handbook recommend?

  1. A.
    Hold your speed and lane; the merging driver must yield.
  2. B.
    Brake hard to create a gap.
  3. C.
    Accelerate to close the gap and block the merging vehicle from entering ahead of you.
  4. D.
    Move over a lane, or adjust your speed a little. Correct
The Why

The answer is "Move over a lane, or adjust your speed a little."

The Side Space Cushion section tells freeway drivers to make room for vehicles entering freeways: if there is no one next to you, move over a lane; otherwise, help the merging driver by slowing down or speeding up a little. Drivers who remember only that the entering vehicle carries the legal yield obligation fall back on choice A, treating that yield duty as the end of the freeway driver's role and skipping the merge-assist step the manual still puts on the driver already in the lane.

Why the others miss

The traps in the wrong answers

A. Hold your speed and lane; the merging driver must yield.

The entering vehicle does carry the legal yield obligation, but the manual still puts merge-assist on the freeway driver: move over a lane, or adjust your speed a little to help open a gap. This answer falls back on the driver-already-in-the-lane instinct that the merging vehicle's yield duty ends the freeway driver's role.

B. Brake hard to create a gap.

The manual asks for slowing down a little, not slamming the brakes; hard braking on a freeway invites a rear-end hit from the driver behind you. This answer confuses the small speed adjustment the manual describes with the panic-brake reflex drivers reach for when a merger appears close.

C. Accelerate to close the gap and block the merging vehicle from entering ahead of you.

The manual's 'speeding up a little' is a small adjustment that opens a gap for the merger; closing the gap forces the merging driver to brake or stop on the ramp, the exact hazard the merge-assist rule is meant to prevent. This answer treats the freeway lane as territory to defend and reads any on-ramp merger as a queue-jumper, the 'don't let them in' reflex drivers pick up in heavy commute traffic.
