Question 1770 in the bank

A cement mixer is:

  1. There is no proper definition for cement mixers.
  2. An off-road vehicle.
  3. Correct answer: a commercial truck.
  4. A special-purpose vehicle.

Why this is the answer

The correct answer in the official bank: a commercial truck.

A cement mixer is built to carry a load, fresh concrete, from the plant to the building site, so it counts as a commercial truck, a goods vehicle. The rotating drum is just equipment that keeps the load usable during the trip. Calling it a special-purpose vehicle is tempting, but any vehicle whose main job is carrying cargo is a goods vehicle, even with special equipment.
