17 Del. C. § 524

(a) Legislative findings. — The General Assembly finds that persons and firms post nonofficial signs on utility poles without prior authorization from the pole owner. Placing such signs on these poles is unsafe, both for the person attaching the sign and those in the vicinity of such activity when it occurs, including passersby. Therefore, it is appropriate to authorize the Department of Transportation to treat such signs as subject to immediate removal and other enforcement action under §§ 525 through 527 of this title, without regard to the clear zone distance limitations of those sections.

(b) The Department of Transportation may treat any nonofficial signs placed on utility poles at any location within the State’s rights-of-way as artificial obstructions within the clear zone, subject to immediate removal and other enforcement action under §§ 525 through 527 of this title, upon confirmation that the utility company had not previously authorized the placement of such signs.
