Traffic control devices at railroad-highway grade crossings.

Every railroad company operating or leasing any track intersecting a public road at grade and upon which railroad trains are operated shall erect traffic control devices that are necessary to conform with the requirements of the uniform system of traffic control devices adopted pursuant to s. 316.0745. This section does not require the railroad company to erect those devices, such as pavement markings and advance warning signs, which are the responsibility of the governmental entity having jurisdiction over or maintenance responsibility for the public road. Any change in the design of a traffic control device in the uniform system of traffic control devices applies only at new installations and at locations where replacements of existing devices are being made.
