Oregon Practice Lane Changes & Merging

How far in advance must you signal before a lane change in Oregon?

  1. A.
    At least 100 feet. Correct
  2. B.
    Whenever it's convenient, no minimum distance.
  3. C.
    At least 50 feet.
  4. D.
    At least 200 feet.
The Why

The answer is "At least 100 feet."

If your vehicle is moving in traffic, you must use your turn signal at least 100 feet before a turn or lane change. The 100-foot rule applies whether you're turning at an intersection, changing lanes on a freeway, or changing lanes on a city street. When pulling away from a curb after parking, signal long enough to alert traffic; no specific distance is set for that case. Cutting the required distance in half is what pulls a driver toward C rather than the 100-foot minimum the manual actually sets.

Why the others miss

The traps in the wrong answers

B. Whenever it's convenient, no minimum distance.

The manual is explicit about a 100-foot minimum. This answer ignores the manual's explicit 100-foot rule by treating signal timing as discretionary.

C. At least 50 feet.

Oregon requires at least 100 feet, not 50. This answer halves the required signal distance; the manual sets the minimum at 100 feet, not 50.

D. At least 200 feet.

200 feet exceeds the requirement. This answer doubles the required distance; the manual specifies a 100-foot minimum, not 200.
