Outdoor Advertising Program

DOTD's Outdoor Advertising department is responsible for the regulation and control of outdoor advertising and junkyards. In 1965 President Lyndon B. Johnson signed into law the Highway Beautification Act, also called the Lady Byrd Johnson Act. The objectives of the Act are to regulate the placement of outdoor advertising signs, displays and devices in areas adjacent to designated highways in order to protect public investment, to promote the safety and recreational value of public travel and to preserve natural beauty.

It is the policy of the State of Louisiana that the erection and maintenance of outdoor advertising and junkyards, in areas adjacent to the interstate and primary highway system, be regulated by rules and regulations promulgated by Louisiana's Administrative Code Title 70.



Campaign Signs

During campaign season, the landscape blooms with a special kind of flower - the political sign. Unlike wildflowers that are welcome anywhere, putting campaign signs on public lands is illegal. So before you plant that sign, learn the law and keep Louisiana beautiful.

What You Need to Know:

    • It is illegal to place any signs on or within the right of way. This includes posting signs on trees, telephone poles, traffic signs and other objects on the right of way.
    • Campaign signs along Louisiana roads can be placed on private property with the owner's permission
    • Signs must be made of lightweight material and be no larger than 50 square feet.
    • Campaign signs may be posted as early as 90 days before an election (no earlier) and must be removed within 10 days after the election.
    • Before placing a sign inside of incorporated city limits, check with the city for applicable ordinances.

Sign Removal

If you've placed your sign in the right of way or it's posing a traffic hazard, we will remove it without prior notice. All costs associated with sign removal will be paid by the sign owner.
