A loaded hopper barge with independent tanks has a placard, with alternating red and white quadrants, on each side and end. Which statement concerning this barge is TRUE?

Correct Answer: Option C — The barge must be in a protected position within the tow.

Under 46 CFR 151.45-4, barges displaying the alternating red and white quadrant placard carry highly hazardous cargoes, such as chlorine or anhydrous ammonia. Regulations mandate that these barges must be placed in a protected position within the tow to minimize collision damage.
