The driveway leads to US 17 but not before intersecting part of a frontage road along the southbound lane whose right-of-way originates along the overlap with Interstate 95 south of the northern terminus of that overlap at Exit 33, The sign is reads "SLOW" in a yellow diamond behind a yellow field with lettering underneath reading "Proceed With Caution." Signs like this do not meet the standards of the Manual on Uniform Traffic Control Devices in the United States, but since it's on private property, it's considered acceptable. On the other hand, signs like this can be found in other parts of the United States, because they're manufactured by various sign-making companies.
