The Utah Department of Transportation is reminding candidates for political office that it is unlawful to put campaign signs on highway rights of way.

"Under the National Highway Beautification Act and the Utah Beautification Act, it is illegal to place signs along state highways without permits," said department spokesman Kim Morris.Morris said that means political signs of any type are not allowed on telephone or utility poles, fences, trees or existing official signs located in the rights of way.

Highway crews have been instructed to remove all political signs that violate the law - a costly endeavor.

"The department is requesting the cooperation of all candidates in helping keep campaign advertising off highway rights of way," Morris said.
