Rules of the roadQuestion 287 of 566

Why is it dangerous to cross a tug's tow line?

  1. The line is always very short.
  2. The line is always lit.
  3. The tug cannot move.
  4. The line may hang under the water and be nearly invisible.
Show answer

Correct answer: The line may hang under the water and be nearly invisible.

A small boat that hits the hidden line can flip, and the tow may then run it over.
