In clear daylight, lumber on a pickup extends five feet beyond the rear of its bed. It is not a commercial load of unprocessed logs or pulpwood. How must the projection be marked?

Correct answer: Red flags at least 18 inches square at the load's end.

Why

For this five-foot rear projection in clear daylight, display red flags at least 18 inches square at the load extremities where lamps would otherwise be required. From sunset to sunrise and during rain, smoke or fog, a rear projection of four feet or more needs two rear red lamps, two rear red reflectors showing the width, and one red lamp on each side showing the overhang. The lamps must be visible at least 500 feet in their required directions; the reflectors must be visible from 100 to 600 feet in lawful low beams. The special commercial unprocessed-log or pulpwood rule requires amber strobe lighting and a red flag. Secure the load as well as marking it.
