Texas Practice Adverse Conditions

According to the manual, two feet of rushing water is enough to carry away which types of vehicles?

  1. A.
    Only motorcycles and small compact cars.
  2. B.
    Pick-up trucks, SUVs, and most other vehicles. Correct
  3. C.
    All vehicles including tractor-trailers.
  4. D.
    Passenger sedans, but not trucks or SUVs.
The Why

The answer is "Pick-up trucks, SUVs, and most other vehicles."

The manual states two feet of rushing water will carry away pick-up trucks, SUVs, and most other vehicles. Option D reflects the assumption that a truck's weight anchors it, but the manual lists trucks and SUVs by name at this depth.

Why the others miss

The traps in the wrong answers

A. Only motorcycles and small compact cars.

The manual's two-foot line reaches well beyond motorcycles and compacts; it includes trucks and SUVs. This answer assumes only the smallest vehicles float, drawing on the intuition that heavier means anchored.

C. All vehicles including tractor-trailers.

The manual says two feet carries away pick-up trucks, SUVs, and "most other vehicles," not every vehicle. Choice C stretches that phrase to include tractor-trailers, which the manual does not name at this depth. This answer rounds "most other vehicles" up to "all vehicles" on the reasoning that if two feet floats a pick-up, it must also carry a fully loaded rig.

D. Passenger sedans, but not trucks or SUVs.

The manual specifically names pick-up trucks and SUVs as vehicles two feet of rushing water carries away. This answer trusts a truck's weight to hold the ground, an assumption the manual contradicts by naming trucks first.
