The commissioner may enter into agreements for public or private sponsorship of highway safety rest areas by transportation and tourism-related entities. The commissioner may publicly acknowledge sponsors and may erect signs adjacent to the main travel lanes of a highway acknowledging the sponsors. Acknowledgment on the main line may consist of placement of up to one sign for each direction of traffic served. The placement of signs shall only be allowed (1) as approved through the Manual on Uniform Traffic Control Devices process for experimentation, (2) in accordance with federal standards and policies, and (3) so that no sign exceeds 100 square feet. No more than three acknowledgment signs or displays may be placed at any one rest area, in addition to the main-line signs.
The commissioner shall deposit revenue from the sponsorship program to the safety rest area account established in section 160.2745.
The commissioner shall take no action under this section that would result in the loss of federal highway funds or require the payment of highway funds to the federal government.
