Oregon Practice Lane Changes & Merging

You're using an on-ramp to enter an Oregon freeway. What's the correct merging procedure?

  1. A.
    Stop at the end of the ramp and wait for a gap to merge.
  2. B.
    Speed up to match freeway traffic and yield to vehicles already on the freeway. Correct
  3. C.
    Merge at your current speed; traffic already on the freeway must slow or change lanes to let you in.
  4. D.
    Drive on the shoulder until you find a gap.
The Why

The answer is "Speed up to match freeway traffic and yield to vehicles already on the freeway."

Use the on-ramp to speed up and match freeway traffic. You must yield to vehicles already on the freeway; they don't yield to you. Check your mirrors and blind spots, signal, and merge during a gap. Keep moving if possible: drivers behind you on the ramp expect you to speed up, not slow down. Stopping on a freeway on-ramp is dangerous unless a ramp meter requires it. The manual does tell freeway drivers to adjust their speed to permit a safe, smooth merge, but that instruction does not transfer the right of way; the legal duty to yield stays with the entering driver.

Why the others miss

The traps in the wrong answers

A. Stop at the end of the ramp and wait for a gap to merge.

Stopping at the end of an on-ramp is dangerous; the manual says to keep moving if at all possible and use the ramp to speed up to match freeway traffic. Drivers behind you on the ramp expect you to speed up, not slow down. Misreading: Treats the on-ramp like a yield or stop entrance instead of a merge ramp; ignores the manual's instruction to keep moving if at all possible and use the on-ramp to speed up.

C. Merge at your current speed; traffic already on the freeway must slow or change lanes to let you in.

The manual tells freeway drivers to adjust their speed to permit a safe, smooth merge, but that instruction does not transfer the right of way. You must yield to traffic already on the freeway, and you should speed up on the ramp rather than hold your ramp speed. Misreading: Turns the manual's instruction that freeway drivers adjust speed to permit a safe, smooth merge into a legal duty to yield, reversing the rule that the entering driver must yield to traffic already on the freeway.

D. Drive on the shoulder until you find a gap.

The shoulder is not a travel lane; the manual says it should only be used in an emergency. Misreading: Treats the shoulder as an extra merge lane; the manual reserves the freeway shoulder for emergency use only.
