A farm tractor ahead of you signals a left turn. What should you conclude?

  1. A.
    The tractor is waving you through to pass on the left
  2. B.
    The tractor has stopped and needs assistance
  3. C.
    The tractor is preparing to turn left, so do not pass Correct
  4. D.
    The tractor is moving right so you can pass on the left
The Why

The answer is "The tractor is preparing to turn left, so do not pass"

A left-turn signal on farm equipment means the operator is preparing to turn left, and passing at that moment sends you into a sideswipe or angle crash with the machine as it swings across your lane. The 'waving you through' trap is the exact mistake the manual names, and readers who pick it are borrowing from the two-lane rural custom where a slow driver flashes a left signal to invite the car behind to come around.

Why the others miss

The traps in the wrong answers

A. The tractor is waving you through to pass on the left

A turn signal announces a turn; it is not a wave-through gesture from the operator. This answer reads a mechanical turn signal as the informal wave-to-pass slow drivers sometimes use on two-lane roads, the exact mistake the manual singles out.

B. The tractor has stopped and needs assistance

A left-turn signal is directional; it tells you the equipment is preparing to turn left, not that the operator needs assistance. This answer treats a directional turn signal as an emergency signal, applying a habit built from watching hazard flashers on stalled cars.

D. The tractor is moving right so you can pass on the left

Nothing in a left-turn signal tells the driver behind to expect the tractor to pull right; the operator is turning left. This answer inverts what a left signal means, borrowing from courtesy-pull-over customs where slow drivers drift onto the shoulder without any signal at all.
