Highway Administration Humor Allowance Act

This bill removes a provision from the Federal Highway Administration's traffic control manual that permitted humor in safety messages. It specifically invalidates Provision 04 of Section 2L.07 in the Manual on Uniform Traffic Control Devices, which had allowed for lighthearted wording on road signs. The change affects how the Federal Highway Administration enforces traffic control standards nationwide. The bill does not create new rules but eliminates an existing allowance for humor in official safety messaging.
