Why must you continue obeying orange signs, cones, and barriers even when workers are not immediately visible?
A travels between two rows of cones inside a work zone. The marked channel continues ahead; no flagger is shown.
Correct answer: They can mark a lane shift or hazard beyond your view.
Why
Scan the entire work zone and follow its signs, channelizing devices, signals, and lawful directions. Workers may be absent while a closed lane, uneven surface or other temporary hazard remains. Cones and barriers continue to define a usable route until the controls are removed or changed.
